Picture a thriving dairy farm where every Holstein cow is at its peak, producing the highest quality milk, and culling rates are at their lowest. The secret to this success? It’s the transformative power of rumen-protected methionine, a simple yet potent treatment. You can significantly increase milk fat content and reduce culling rates by feeding rumen-protected methionine at the critical peripartum phase. This crucial vitamin can unlock your herd’s full potential, ushering in a new era of production and profitability.

Understanding Rumen-Protected Methionine

Methionine is not just any amino acid; it’s an essential one that dairy cows cannot produce independently. It plays a unique and crucial role in protein synthesis, metabolic function, and the creation of keratin, which is vital for hoof health. In nursing cows, methionine is also required for optimum milk protein production.

Rumen-protected methionine is a dietary supplement used in dairy cow nutrition to guarantee that methionine, an essential amino acid, is efficiently transported to the small intestine for absorption rather than being destroyed in the rumen. This technique improves dairy cows’ nutritional efficiency and health, producing higher milk output and quality.

Rumen-protected methionine is intended to circumvent the rumen fermentation process. This is often accomplished by encapsulating or coating methionine with compounds that can withstand degradation by rumen microorganisms while dissolving in the small intestine’s lower pH.  Here’s the step-by-step process:

  1. Encapsulation: Methionine is coated with a protective layer, often made from fats or pH-sensitive polymers.
  2. Rumen Bypass: The encapsulated methionine passes through the rumen without being degraded by the microbial population.
  3. Release in the Small Intestine: Once in the small intestine, where the environment is less acidic than in the rumen, the protective coating dissolves, releasing the intact methionine for absorption into the bloodstream.

A Game Changer for Holsteins

As you may already know, rumen-protected methionine (RPM) is essential to dairy cow diets. Researchers have been working to guarantee that it provides the most advantages, particularly for high-productivity dairy cows such as Holsteins. New research suggests that including RPM in a cow’s diet significantly improves lactation performance under demanding situations such as heat. Pate et al. found that RPM dramatically increases milk’s protein and fat contents during these stressful times. The results represent a significant milestone in the dairy farming business.

A targeted meta-analysis between 2010 and 2022 extensively analyzed RPM’s influence on dairy cows’ nutritional intake, milk output, accurate milk protein synthesis, and milk fat yield. The research shed light on RPM’s functional duties and offered valuable advice on using it most effectively. Increasing milk fat and protein content increases the value of dairy products, including milk, cheese, and yogurt. As a result, RPM not only improves Holstein cow health and nutrition, but it also benefits the commercial dairy industry.

Interestingly, feeding RPM during the peripartum period was more effective than giving choline. Dairy cows’ postnatal performance increased when RPM was added to their diet before and after birth. This method increased lactation performance and optimal plasma amino acid concentrations, providing nutritional benefits to the cows. This may boost milk output and enhance herd health, benefiting dairy producers financially. The goal is to achieve the ideal RPM feeding ratio while ensuring cow well-being and increased milk output. This study examines the impact of rumen-protected methionine in the total mixed diet before and after the calf’s birth on dairy cow lactation performance and plasma amino acid levels.

Unlocking the Potential: Benefits of Feeding Rumen-Protected Methionine

You’re on the right track if you’ve incorporated rumen-protected methionine (RPM) into your feed regimen. Multiple studies from 2010 to 2022, conducted with rigorous scientific methods, have consistently shown that this supplement improves dairy cattle’s health and output capability. These are anecdotal outcomes and solid evidence of RPM’s efficacy, giving you confidence in its benefits. Cows given rumen-protected methionine saw a significant increase in milk output by 1.5 kg/day.

Indeed, the value of RPM stems from its fantastic persistence. Its changed shape guarantees that it can endure the rumen’s harsh environment. By avoiding the danger of deterioration, high-yielding dairy cows may thoroughly enjoy the beneficial properties of this vitamin. Incorporating RPM into your dairy cows’ diet considerably boosts milk fat and protein content, solving issues about low-quality milk production. Recent research found that methionine supplementation throughout the peripartum period raised milk fat content by 0.2%, thereby improving milk quality.

The advantages extend beyond improved milk quality. Methionine, in its rumen-safe form, has shown to be an ally throughout the searing summer months, assisting cows in dealing with heat stress and enhancing their overall performance. This supplementation has also resulted in a 10% drop in culling rates and the occurrence of metabolic diseases, ensuring optimum animal care while reducing long-term expenses. Using RPM improves both your herd’s health and your financial line, demonstrating your dedication to both.

The direct delivery of methionine to the small intestine offers several benefits:

  • Enhanced Milk Production: By maintaining proper methionine levels, dairy cows may produce milk with a higher protein content, which is critical for dairy profitability.
  • Improved Milk Quality: Methionine raises milk’s casein content, improving its nutritional value and processing properties.
  • Better Animal Health: Adequate methionine promotes improved hoof health and general physiological processes, lowering the likelihood of conditions such as laminitis.
  • Efficient Feed Utilization: Protecting methionine from rumen breakdown enables more effective utilization of feed proteins, potentially lowering feed costs.

Feeding RPM before and after calving (during the peripartum period) leads to significant lactation performance gains, as seen by high amino acid concentrations in dairy cow plasma. This precedent-setting decision is supported by other investigations, including the 2020 deep-dive research done by Pate, Luchini, Murphy, and Cardoso. Science has never spoken louder. Adding rumen-protected methionine to your Holstein cows’ diet promotes fat-filled milk output and improves farm stability. Pivot to RPM now and put your herd up for unrivaled success.

The Power of Peripartum Nutrition: A Strategy to Curb Culling Rates

You may wonder how this extraordinary rumen-protected methionine (RPM) contributes to lower culling rates. Buckle up because we’re about to discover some incredible details. Culling rates in Holstein cows fell by 5% with the introduction of rumen-protected methionine. It is vital to note that the peripartum interval, which lasts three weeks before and after parturition, is a critical time of metabolic shift for dairy cows. Dietary shortages in this crucial period might cause health problems, increasing culling rates. This is when RPM comes into play.

Researchers discovered that RPM had a much more significant influence on postpartum performance in cows given with it than choline during periportal intervals. This supplement may help increase energy-corrected milk output, protein content, and nitrogen efficiency. RPM was also shown to improve embryo size and fertility in multiparous cows—a significant result given that a more extensive, healthier calf has a greater chance of survival and production. A recent study of 470 multiparous Holstein cows found that RPM improved lactation performance even under heat stress, indicating that its effects do not decline under less-than-ideal settings.

RPM is more than a nutrition supplement; it is a game changer focusing on dairy cows’ long-term health and production, reducing culling rates. Implementing a comprehensive peripartum feeding strategy that includes RPM may significantly boost a commercial herd’s performance.

The Bottom Line

As we conclude, consider how rumen-protected methionine transforms the dairy industry’s future. This innovative supplement has changed the game by drastically increasing milk fat content and lowering culling rates in Holsteins. These significant results have raised expectations for high-quality dairy products and long-term profitability in large-scale enterprises. While critical details, such as the mechanics of methionine supply, remain unknown, ongoing research supported by business collaborations promises a better future. The complicated interaction of nutrition and energy is critical. With rumen-protected methionine, Holsteins are positioned for more excellent health, increased output, and less culling—a fantastic outcome for the industry.

Have you ever wondered why some cows produce more milk than others? Surprisingly, the solution often rests in events before the milking process starts. Calving ease and age are crucial but usually ignored elements influencing dairy farm output. Understanding these critical variables may mean the difference between standard and exceptional milk output.

In this post, we’ll look at the subtleties of calving ease and age at first calving, using data from an extensive survey of 687 dairy farms in the United States. We’ll look at how these variables affect your cows’ milk output, energy-corrected milk, and the fat and protein composition of the milk. What’s the goal? To provide you with practical information that will help you maximize your herd’s performance and, eventually, your bottom line.

The Importance of Calving Ease 

Have you ever considered how calving ease (CE) impacts the success of your dairy operation? As stated, CE describes how cleanly a cow gives delivery. Higher ratings suggest more complex deliveries, which may lead to issues for the cow and the calves.

CE scores vary from 1 to 5, with one indicating ease and 5 indicating great difficulty. These values are essential because difficult calvings may influence overall herd health and production. For example, calvings with a CE score of more than two considerably impact milk production (MP) and the fat and protein composition of the milk. Cows earning a 4 in CE showed a significant drop in milk production, with the lowest lactation peaks among the tested breeds: Holstein (43.1 kg/d), Jersey (35.8 kg/d), and dairy hybrids.

But it isn’t just about the milk. Complications associated with difficult deliveries can affect calf growth. Poor CE scores may slow calf development, making the first few days of life especially more essential. The research, which comprised over 1 million CE observations from 687 dairy farms in the United States, offers critical insights into these effects.[[Source

Understanding and increasing CE may help your dairy farm achieve increased productivity and healthier animals. So, the next time you analyze herd performance, consider how CE ratings may impact your bottom line.

Understanding Age at First Calving (AFC)

The age at first calving (AFC) is when a young female cow (a heifer) gives birth for the first time. This milestone is essential in dairy production for a variety of reasons. Proper AFC may significantly improve milk output, herd health, and farm profitability.

Why AFC Matters 

Your cows’ AFC has an impact on their long-term production and health. For example, optimum AFC may result in higher milk production and more efficient reproductive function. Conversely, premature or severely delayed calving might have unfavorable consequences. So, what is the ideal AFC for various breeds?

Optimal AFC for Different Breeds 

According to research, the ideal AFC differs by breed. For Holsteins, the optimal AFC is about 27 months, whereas for Jerseys, it is around 22 months. This is based on thorough research that included 794,870 calving ease (CE) observations from many breeds.

The AFC-Milk Production Connection 

Your cows’ milk output is strongly linked to their AFC. Cows who calve at the appropriate age produce more milk, peak sooner, and have superior overall health. Cows having a CE score of more than 2 demonstrated a decrease in milk output and components. A CE score of 4 indicated the lowest milk output, with Holsteins, Jerseys, and crossbreeds producing 43.1, 35.8, and 39.2 kg/d of milk at peak lactation, respectively.

AFC and Herd Health 

In addition to milk production, AFC influences overall herd health. Cows who calve at the right age have fewer difficulties and higher fertility and survival rates. Breeding at the correct time helps avoid the hazards of early or late births, lowering veterinary expenditures and boosting the herd’s overall health.

Connecting Calving Ease (CE) and Age at First Calving (AFC): Impacts on Milk Production 

Connecting calving ease (CE) with age at first calving (AFC) provides insights for dairy producers. The research demonstrates that both variables have a considerable impact on milk output. Let’s see how.

First, calving ease is critical. When the CE score exceeds 2, the milk supply diminishes. Cows with a CE score of 4 produce much less milk, with Holsteins averaging 43.1 kg/d, Jerseys 35.8 kg/d, and dairy crosses 39.2 kg/d. Difficult calvings might reduce a cow’s capacity to produce milk efficiently. These limitations apply to raw milk output, energy-corrected milk (ECM), and fat and protein content.

Age at first calving (AFC) is equally important. According to the research, AFC has a quadratic effect on CE. Holsteins calving at 27 months and Jerseys at 22 months had the lowest CE values. Younger cows—those calving for the first time—tended to have smoother calvings, maximizing milk yield and composition.

The age at first calving also impacts CE’s effect. When AFC is included as a covariate, previously observed CE interactions with covariates, such as calf sex and breed, become less significant. The ideal AFC mitigates the negative consequences of high CE scores, resulting in increased milk output and healthier cows.

So, what is the takeaway? Careful management of both CE and AFC may dramatically increase your herd’s output. Ensure your cows calve easily and at the appropriate age to optimize their milk production potential. Your efforts may increase milk production, better energy-corrected milk, and more significant fat and protein content, providing more value and efficiency in your dairy business.

Boosting Milk Production: The Impact of Calving Ease and Age at First Calving

According to a survey of 687 dairy farms, cows with a calving ease score of more than 2 had lower milk output and components, with the lowest values recorded in cows with CE = 4 (source). For example, Holstein, Jersey, and dairy crosses (XD) with CE = 4 showed the lowest milk lactation peak (MLP), averaging 43.1, 35.8, and 39.2 kg/d, respectively. The study found that the linear and quadratic components of Age at First Calving (AFC) were significant, emphasizing the need to regulate CE and AFC to achieve optimum output results.

The research found that cows birthing males had higher CE scores, with Holsteins having the lowest CE at 27 months and Jerseys at 22 months AFC. Addressing these factors may increase production and improve overall dairy farm performance (source).

Intrigued? Let’s dig in and see what these changes imply for you and your farm.

The August 2024 CDCB Evaluations Brought Several Noteworthy Updates. Let’s Break Them Down: 

The August 2024 CDCB evaluations brought several noteworthy updates. Let’s break them down: 

  • 305-AA Standardized Yield Measurement: This revision establishes a new standard for yield records, moving from 305-ME mature equivalent to a 36-month average age. It also revises age, parity, and season adjustment factors. This standardization is more precise in capturing environmental variables and is breed-specific.
  • Heifer Livability: The revised Heifer Livability ratings incorporate two years’ worth of lost data and additional editing criteria tailored to herd circumstances. This increases dependability and influences linked qualities such as Productive Life (PL) and Cow Livability (LIV).
  • SNP List and BBR Reference Population Updates: These changes include a new SNP list and a BBR reference population update, affecting purebred and crossbred animals’ status and genetic assessments. This modification has raised assessment variability, particularly in hybrid animals genotyped at low density or with incomplete pedigrees.

Why the 305-AA Change Matters for Your Dairy Farm’s Future 

The launch of 305-AA has sparked interest among dairy producers. This is a gradual change but a substantial shift in how yield data are standardized. So, what precisely is 305-AA? Essentially, it is a technique of standardizing yield data that uses a 36-month average age rather than the older 305-ME (mature equivalent). This implies that the new approach considers the average age, parity, and seasonal modifications for five climatic areas in the United States. These improvements are intended to provide a more realistic picture of environmental variances. It is also breed-specific; therefore, the influence varies according to the breed.

Why does this matter? Accurate yield data is critical for making educated breeding and herd management choices. The new changes consider more specific environmental characteristics, providing a more precise evaluation customized to each breed.

Let’s get specific. For Holsteins, the 305-AA modification improved the Predicted Transmitting Ability (PTA) for Milk, Fat, and Protein. This has resulted in a minor increase in the Lifetime Net Merit $ (NM$) index, which typically ranges from +10 to +15 NM$, depending on whether we’re talking genetic or proven bull groupings. This is a welcome improvement for anyone interested in Holsteins.

On the other hand, the Jerseys have not fared well. Their PTAs for milk, fat, and protein decreased significantly—by around 100, -6, and -6 pounds, respectively. As a result, their NM$ index declined by an average of -70 to -50 NM$. Jersey breeders may be concerned about the long-term economic worth of their herds. Understanding the reasons for these changes in the Jersey breed is essential, as they can influence future breeding decisions.

You may ask why these adjustments were made. The fundamental goal is to improve the precision and accuracy of genetic tests, allowing you to make more informed choices about the future of your herd. While the change may be difficult for certain breeds, notably Jerseys, the ultimate objective is to use more accurate data to increase productivity and profitability. This reassurance should give you the confidence to make the best decisions for your herd.

Spotlight on Heifer Livability: Unpacking the CDCB Updates 

The most recent CDCB revisions concentrate on heifer longevity values. Incorporating two years’ worth of previously overlooked data has resulted in larger-than-usual adjustments. Consider this: all of those missed records are suddenly coming into play! This change contributes to a better picture of heifer longevity, boosting animal dependability.

But that is not all. New editing criteria also focus more on herd circumstances. Although this is a modest change, it has a significant effect. Dairy producers like you can make better choices with more thorough and accurate data.

These Heifer Livability alterations also affect linked attributes. Productive Life (PL) indicates a minor average reduction of roughly -0.2. Cow Livability (LIV) is also indirectly impacted. How does this affect your day-to-day operations? Reliable data allows you to trust these assessments, knowing that the figures you’re looking at are more realistic representations of your herds.

SNP List and BBR Updates: What’s the Impact on Your Crossbred Animals? 

The newest upgrades to the SNP list and BBR reference population have resulted in significant modifications. What’s fascinating is how these updates affect crossbred animals and the variation in their judgments. The reduced SNP list provides a more focused view of genetic markers, resulting in more accurate statistics.

However, increased accuracy leads to more considerable variability in crossbred assessments. Animals genotyped at low density or with inadequate pedigrees are especially vulnerable. In these circumstances, variations in BBR levels may substantially impact whether they are purebred or mixed. This directly affects the final Predicted Transmitting Abilities (PTAs) for crossbred animals, resulting in a wider variety of assessment outcomes.

The haplotype status has also changed due to the SNP list update. Specifically, changes to HH6 (the sixth Holstein haplotype regulating fertility) and JNS (Jersey Neuropathy with Splayed Forelimbs) have been improved to integrate more direct data. This implies that your herd’s genetic assessments are more accurate than ever. Be prepared for unexpected changes in particular animal ranks, but rest assured that you are now equipped with the most precise information to adapt to these changes.

Picture This: You’re Making Breeding Decisions and Planning for the Future of Your Herd 

The most recent revisions to the CDCB assessments might be game-changers. How, you ask? Let’s dig in.

First, the new standardized yield measurement, 305-AA, significantly impacts yield attributes. An increase in Predicted Transmitting Ability (PTA) for Milk, Fat, and Protein may lead you to consider breeding Holsteins. “The slight upward trend of about +10 to +15 NM$ depending on the bull group can improve your herd’s overall productivity,” says industry expert Paul VanRaden [source]. In contrast, the significant fall in PTAs may cause you to rethink utilizing Jerseys for yield-based objectives for Jersey cattle.

The latest revisions to Heifer Livability include larger-than-usual modifications due to incorporating two years’ worth of missing information. This may influence your judgment on which heifers to keep or cull. Since Productive Life (PL) declined by an average of -0.2, you may choose heifers with higher livability ratings to maintain a more productive and long-living herd.

These modifications may have a financial impact on your income sources. For example, the new SNP list and BBR reference population updates may induce heterogeneity in crossbred animal assessments, particularly for those genotyped at low density or with incomplete pedigrees. If your farm uses mixed animals, you should reconsider the economic sustainability of retaining or growing this segment of your herd.

Consider the implications of HH6 and JNS haplotype status updates. With these new genetic insights, choosing animals that test negative for certain illnesses may become a priority, affecting your financial plans. Jay Megonigal emphasizes the need for rigorous herd management, citing recent studies that show high relationships between changes.

What’s the bottom line? These updates need dynamic changes to breeding techniques, herd management, and financial estimates. As a dairy farmer, remaining knowledgeable and adaptable is critical for adjusting to changing requirements and maintaining a healthy enterprise.

The Bottom Line

To wrap it up, the August 2024 CDCB evaluations have introduced significant changes essential for your farm’s sustainability and profitability. These adjustments can impact your herd’s genetic evaluations and overall performance, from the 305-AA standardized yield measurement to Heifer Livability, SNP lists, and BBR values updates. Staying informed about these updates can help you navigate the changes and plan effective breeding decisions. So, how will you adapt to these new evaluations to ensure your herd’s success? Keeping a close eye on these evaluations and understanding their implications can give you a competitive edge. Remember, your proactive approach could mean the difference between thriving and just getting by.

August 2024 Genetic Evaluations: Key Updates and Innovations from CDCB and USDA AGIL

Discover the latest updates in genetic evaluations from CDCB and USDA AGIL. How will the new 305-AA yield measurement and Constructed IDs impact your herd?

CDCB and USDA Animal Genomics and Improvement Laboratory (AGIL) implemented essential changes to improve genetic assessment accuracy on August 13, 2024. This paper underlines these critical developments and their advantages for the dairy sector. Supported by USDA AGIL’s innovative genomics research, CDCB is well-known for its exact genetic assessments. Among other improvements, the adoption of Constructed IDs and 305-AA standardized yield measurement highlights their dedication to precision and innovation, increasing the dairy industry’s output and sustainability.

CDCB and USDA AGIL Introduce the New Standardized Yield Measurement Known as 305-AA 

In a step meant to transform dairy genetics, the USDA AGIL and CDCB have unveiled the new standardized yield measurement known as 305-AA. This much-awaited change departs significantly from the mature equivalent (ME) standard, effective since 1935. Standardized yield records now benchmark the average age of 36 months or 305-AA. Inspired by current studies, this adjustment marks a methodological turn to reflect a more contemporary dairy environment.

The new 305-AA yield assessment replaces changes relied upon over the last 30 years and incorporates updated age, parity, and season parameters. The recalibrated changes seek to permit fair phenotypic comparisons among cows of various ages, sexes, and calving seasons. The main objective is to evaluate dairy performance under many settings and management strategies.

One significant modification is adjusting herd averages to approach real yields. Under the former ME method, breed-specific yield projections varied by around 10 percent higher than actual yields. Effective June 12, 2024, the estimates of the 305-AA yield become available via CDCB’s WebConnect for animal and data searches. Moreover, the officially adopted, on August 13, 2024, new 305-AA changes are entirely included in the CDCB genetic examinations.

Table 1. The ratio of mature equivalent to 36-month equivalent milk, fat, and protein yields from 1994 or recent data

Breed1994 FactorME / 36-month SD ratio in recent data
  MilkFatProtein
Ayrshire1.101.0921.0761.067
Brown Swiss1.151.1561.1501.142
Guernsey1.051.0431.0091.013
Holstein1.101.0821.0811.059
Jersey1.101.0791.0631.064
Milking Shorthorn1.151.1101.1001.090

This move from 305-ME to 305-AA offers a perceptive analogy. Recent data shows that standardized yields calculated from the 1994 ME factors are routinely more significant than those adjusted to the 36-month equivalent. This change marks a reassessment of yield projections to more closely reflect the contemporary dairy environment and current dairy animal performance.

A vital component of this shift is the modification in standard deviation (SD) “ME / 36-month” ratios, usually seen to be somewhat greater in earlier data than in recent changes. These little variations indicate calibrating output estimations to fit modern dairy production methods and genetic developments.

For predicted transmitting abilities (PTAs), these changes have significant ramifications. Updated ratios closer to 1.08 for Holsteins (HO) and Jerseys (JE) and generally more tiny numbers for fat and protein point to a minor scaling or base adjustment in PTA values. These changes assist representative assessments of dairy cow genetics, improving the validity and applicability of these measures according to contemporary industry requirements. Thus, a sophisticated, data-driven approach to genetic studies helps the dairy industry by promoting informed breeding and management choices.

Enhancing Precision: Modern Dairy Environments and Refined Seasonal Adjustments

Recent data analysis has improved seasonal adjustments to reflect the effect on lactation yields of the changing dairy environment. Modern architecture and construction methods have lessened the seasonal impact on yields, hence stressing improvements in dairy settings. The revised approach reveals minor variations by estimating seasonal impacts within five separate climatic zones defined by average state climate scores. This change emphasizes the advantages of better dairy conditions, lessening the need for significant seasonal changes and more accurate genetic tests. This method guarantees lactation yields are assessed in a framework that fairly represents current environmental and management circumstances using region-specific modifications, enabling more precise and fair comparisons of dairy output.

Robust Validation: Testing New Factors Across Decades of Lactation Records

The new parameters were tested rigorously using 101.5 million milk, 100.5 million fat, and 81.2 million protein lactation data from 1960 to 2022. The validation focused on the relationships of Predicted Transmitting Ability (PTAs) for proven bulls born after 2000. Results were rather good, with correlations of 0.999 for Holsteins, above 0.99 for Jerseys and Guernseys, and somewhat lower, ranging from 0.981 to 0.984, for Brown Swiss and Milking Shorthorns. These strong connections underscore the dependability of the new elements. The study also observed minor changes in genetic trends: a decline for Brown Swiss and Jerseys and a rise for Guernseys. These revelations help us better evaluate our genes, guaranteeing justice and ongoing development.

Revolutionizing Genetics: The Full Integration of Constructed IDs into the CDCB Database 

When fully adopted by August 2024, Constructed IDs represent a significant turning point for CDCB. Targeting partial pedigrees, particularly for animals without maternal ancestry information, this invention launched in mid-2023 and ends in July 2024. Constructed IDs link approximately 3.2 million animals in the National Cooperator Database to newly discovered relatives, developed by significant research by USDA AGIL using over a decade of genetic technology experience.

This improvement increases the dependability and accuracy of genetic tests. The worldwide influence is significant given these complex interactions across the closely linked U.S. dairy community. More precise breeding choices help directly impacted and related animals to improve their genetic quality and raise U.S. assessments. Designed IDs strengthen the genetic bases for further development by filling critical pedigree gaps.

Refined Criteria and Data Integration: Elevating Heifer Livability Evaluations for Improved Genetic Precision 

Recent improvements in heifer liability (HLV) show how committed the USDA AGIL and CDCB are to accuracy and dependability in genetic assessments. Fundamental changes exclude recent heifer fatalities from 2022–24 and rectify previously missed data resulting from changes in cow termination codes. These wholly integrated reports improve HLV assessments immediately. Improving the speed and depth of evaluations is a crucial modification that calls for a minimum of 1 percent mortality loss annually for the data of a herd to be legitimate. Faster adaptability to evolving reporting methods made possible by this change from cumulative to yearly criteria guarantees current herd health dynamics are faithfully captured. These improvements have generally resulted in a significant increase in the dependability of HLV assessments, particularly for bulls with daughters in the most recent data sets, generating more robust genetic predictions for offspring and informed breeding choices.

Pioneering Genetic Insights: Brown Swiss Rear Teat Placement (RTP) Evaluation

A significant turning point in dairy cow breeding is the introduction of the conventional and genomic assessment for Brown Swiss Rear Teat Placement (RTP). Using about 15,000 assessments from January 2024, CDCB and USDA AGIL accurately calculated the RTP parameters. On the 50-point linear scale, about 80 percent of the evaluations lie between 25 and 35 points. Heritability for RTP is 0.21, somewhat similar to front teat placement at 0.22; repeatability is 0.33.

Ranges for Rear Teat Placement in Brown Swiss

 Predicted Transmitting Abilities (PTA)Reliabilities
Males-2.4 to 3.10 to 98%
Females-3.7 to 2.90 to 79%

For bulls with reliabilities between 0 and 98% and for women between 0 and 79%, the PTA values for RTP in Brown Swiss are -2.4 to 3.1 and -3.7 to 2.9, respectively. This assessment uses exact measures and rigorous statistical techniques and emphasizes genetic heterogeneity within the breed.

Breeding choices depend on this thorough assessment, which helps farmers choose ideal RTP characteristics, enhancing herd quality and production. Driven by reliable, data-based conclusions, the August 2024 release of these assessments marks a new chapter in Brown Swiss genetics.

Refined Precision: Streamlining Genetic Markers for Enhanced Genomic Predictions 

Effective August 2024, the genetic marker update improved the SNPs used in genomic predictions, lowering the list from 78,964 to 69,200. This exact choosing approach removed low call rates, poor genotyping quality, minor allele frequencies, and markers with minimal effects. The X chromosome’s length allowed all SNPs to be maintained there. This update improved efficiency by helping to reduce processing time and storage usage by 12%. About 74% of the deleted SNPs originated from high-density chips.

Five other gene tests—HH7 and Slick, among others—were also included in the update. Confirming the low effect on trait averages and standard deviations, preliminary studies revealed a roughly 99.6% correlation between genomic predictions from the old and new SNP lists. For animals with less dense genotypes or partial pedigrees, this recalibration improves the accuracy of genetic assessments.

Incorporating Genomic Advancements: Annual Breed Base Representation (BBR) Updates

Accurate genetic evaluations depend on annual Breed Base Representation (BBR) revisions. This update, set for August, guarantees that the most relevant genetic markers are included in BBR calculations. Consistent with past upgrades, a test run based on February 2024 data confirmed the stability and strength of the new SNP set. The CDCB maintains BBR calculations at the forefront of genetic assessment by including this improved SNP set, giving dairy farmers the most reliable data for informed breeding choices.

Integrating Cutting-Edge Gene Test Data: Enhancing Haplotype Calculations for Holstein HH6 and Jersey JNS

A significant step forward in genetic assessments is combining Holstein Haplotypes 6 (HH6) and Jersey Neuropathy with Splayed Forelimbs (JNS) direct gene test data into haplotype calculations. By providing thorough gene test results to CDCB, Neogen and the American Jersey Cattle Association (AJCA) have been instrumental in this process. More exact haplotype estimations have come from including these direct gene tests in imputation procedures. Test runs greatly increase performance, Particularly for animals with gene test results and their offspring. This integration improves genetic prediction accuracy and emphasizes the need for cooperation in enhancing dairy cow genes.

The Bottom Line

Incorporating innovative modifications to maximize yield metrics, genetic evaluations, and pedigree correctness, the August 2024 genetic assessments signal a turning point in dairy herd management. These advances improve the dependability and accuracy of tests. While improved seasonal and parity corrections reflect current conditions, the new 305-AA standardizes yield measures for fair comparisons. We designed IDs to decrease pedigree gaps, improving assessments and criteria for Heifer Livability (HLV) and rear teat placement for Brown Swiss. Simplified genetic markers and combined genomic advances such as HH6 and JNS gene testing further improve assessment accuracy. These developments provide consistent data for farmers, enhancing the general health and output of dairy cows. Supported by a thorough study, the August 2024 assessments mark a significant breakthrough and inspire manufacturers to use these innovative approaches for more sustainability and efficiency.

Research has unearthed vital insights into a recessive haplotype linked to elevated calf mortality in Holsteins. This haplotype, which shows incomplete penetrance, means not all calves with the genotype display the syndrome, making detection tricky for breeders and geneticists. Tracing back to 1952, the notable ancestor Southwind (HOUSA1964484), born in 1984, was identified as crucial, being homozygous for the suspect haplotype. 

Scanning sequence data from Southwind and the sire of an affected calf revealed a missense mutation at 79,613,592 bp, likely having a harmful impact. The affected calf was homozygous, while the sire and Southwind were heterozygous. This comprehensive analysis covered 5.6 million Holsteins, showing the haplotype is widespread, complicating management and eradication efforts. 

Breeders face significant challenges with this haplotype’s link to higher calf mortality and incomplete penetrance, necessitating advanced tracking and management methods. Continuous advancements in genetic analysis and breeding strategies are essential to improve calf viability and overall herd health.

The Hidden Genetic Legacy in Holstein Herds: Tracing Calf Muscle Weakness to an Ancestral Haplotype

The genotype analysis of 5.6 million Holstein cattle has revealed crucial genetic insights, linking a specific haplotype to calf muscle weakness. The study focused on DNA variations on chromosome 16, identifying a recessive haplotype associated with increased calf mortality rates. Tracing lineage data back to 1952, researchers identified a bull named Southwind, born in 1984, as homozygous for this haplotype. 

The prevalence of this haplotype underscored the value of genetic monitoring in detecting long-standing patterns within the bovine genome. By combining genotypic data with phenotypic records, the study established the haplotype’s link to muscle weakness, marking a key step in genomic selection strategies aimed at addressing this issue. This breakthrough emphasized the necessity of genetic vigilance to foresee and curtail harmful traits in cattle herds.

Decoding the Genetic Blueprint: Sequencing Efforts Reveal Key Mutations in Holstein Muscle Weakness

The scanning process focused on aligning sequence data from Southwind, the affected calf, and the sire. High-throughput sequencing technologies were employed to pinpoint mutations, emphasizing regions previously linked to the phenotype. The search targeted single nucleotide variants (SNVs) that could affect protein function. 

This analysis revealed a crucial missense mutation at position 79,613,592 bp. This mutation modifies the resulting protein’s amino acid sequence, likely impairing its function. It was homozygous in the affected calf, indicating its probable role in muscle weakness. Conversely, Southwind and the sire were heterozygous, pointing to a recessive inheritance pattern. The concordance in these findings strengthens the link between this missense mutation and the observed calf muscle weakness, suggesting the need for further functional studies.

Harnessing Genetic Concordance: Insights from the Cooperative Dairy DNA Repository

These results highlight the importance of advanced tracking techniques in breeding programs to minimize the impact of such mutations. 

From identifying elevated calf mortality to pinpointing genetic causes, this journey underscores the power of modern pedigree tracking. These methodologies have not only revealed key genetic insights but also paved the way for enhanced herd management and health outcomes for Holsteins. The future of dairy cattle breeding stands to be revolutionized by these advancements, fostering a more precise and informed approach to genetic selection.

Quantifying the Genetic Toll: Heifer Livability Analysis in HMW Homozygous Calves

Analyzing heifer livability records for 558,000 calves revealed vital insights into genetic effects on viability. For the HMW haplotype, 46 homozygous heifers, all tracing back to the ancestor Southwind, were studied. A significant 52% died before 18 months, with an average age of 1.7 ± 1.6 months. In stark contrast, the mortality rate among non-carriers was just 2.4%. This death rate for homozygous heifers might be underestimated due to possible healthier calves being genotyped.

Incorporating Holstein Muscle Weakness (HMW) into Selection and Mating Strategies: Rethinking Reporting Methods and Dominance Effects 

Integrating Holstein Muscle Weakness (HMW) into selection and mating strategies requires rethinking current reporting methods and considering dominance effects. The incomplete penetrance of HMW may cause traditional methodologies to miss or underestimate its prevalence and impact. More accurate reporting is essential to reflect the genetic status concerning HMW. 

Dominance effects further complicate HMW inheritance. Unlike simple recessive traits, HMW’s variable penetrance creates a range of phenotypic expressions that must be considered in breeding decisions. Comprehensive genetic testing, including both genotypic and phenotypic data, will enable informed decisions and help manage partial lethality traits within the herd. 

Direct genetic tests for HMW mutations should be standard in selection protocols, especially for lines tracing back to carriers like Southwind. This approach helps maintain the herd’s genetic fitness without inadvertently continuing the risk of HMW-related calf mortality. By refining these methods, the dairy industry can better balance productivity with animal welfare, fostering a healthier Holstein population.

The Bottom Line

The discovery of a common haplotype linked to calf muscle weakness in Holsteins highlights the importance of genetic research in animal husbandry. Identifying a missense mutation at 79,613,592 bp in the CACNA1S gene, researchers have deepened our understanding of this condition. The analysis, showing a 97% concordance rate, underscores the mutation’s significance. Improved pedigree tracking methods have clarified the relationship between haplotypes and calf mortality, revealing a significant survival rate difference between homozygous calves with the mutation and noncarriers. Direct tests for new mutations within common haplotypes are crucial. These tests provide a precise framework for managing genetic defects, facilitating informed selection and mating strategies, and strengthening Holstein genetic resilience.

Key Takeaways:

  • A novel missense mutation at 79,613,592 bp within a common haplotype on chromosome 16 is associated with calf muscle weakness in Holsteins.
  • The identified haplotype is linked to elevated calf mortality and traces back to an ancestor born in 1984, indicating a long-standing genetic issue within the breed.
  • The mutation was found to be homozygous in affected calves, while the sires and the key ancestor Southwind were heterozygous carriers.
  • Genetic data from the Cooperative Dairy DNA Repository demonstrated a 97% concordance with the identified haplotype, reinforcing the reliability of genetic markers.
  • The CACNA1S gene, associated with muscle function, is highly conserved across species, hinting at parallel phenotypes in humans and mice.
  • Advanced genetic tracking and pedigree analysis methods are crucial for identifying new mutations within existing haplotypes, especially in high-frequency cases.
  • Heifer livability records showed a significant mortality rate among homozygous calves, underlining the condition’s impact on herd productivity and management.
  • Revised selection and mating strategies are necessary to address HMW, including potential direct testing and consideration of partially lethal genetic effects.

Summary: 

Calf muscle weakness, a growing concern in Holsteins, is a significant issue in dairy farming. A recessive haplotype at the end of chromosome 16, traced back to 1952, has been identified in 5.6 million Holsteins, complicating management and eradication efforts. This haplotype’s link to higher calf mortality and incomplete penetrance necessitates advanced tracking and management methods. The genotype analysis of 5.6 million Holstein cattle revealed crucial genetic insights, linking a specific haplotype to calf muscle weakness. The concordance study, leveraging the Cooperative Dairy DNA Repository, found a 97% concordance between sequence data and the haplotype and an 89% call rate, highlighting the reliability of genetic markers and the potential for enhanced genetic tracking and selective breeding to combat inherited conditions. The CACNA1S gene, a key component in muscle function, is highly conserved across different species and is important in various diseases. Modern methodologies have enhanced the precision in identifying new mutations within existing haplotype frameworks.

How Heat Stress Disrupts Milk Quality: Groundbreaking Study Reveals Differences in Holsteins and Brown Swiss

Uncover the influence of heat stress on milk quality in Holstein and Brown Swiss cows. Delve into the pioneering research that highlights the variations in milk microbiota between these breeds.

Have you ever considered the impact of heat stress on dairy cows and their milk? Our groundbreaking studies offer new insights, revealing distinct responses to heat stress between Holsteins and Brown Swiss cows. This research, the first of its kind, is crucial for both dairy producers and consumers, as it sheds light on how high temperatures can affect milk bacteria, thereby influencing milk quality.

The scientists behind this study underscore the practical implications of their findings. They reveal distinct responses to heat stress between Holstein and Brown Swiss cows, particularly in relation to the bacteria in their milk. They stress that improving animal welfare and milk quality in the face of climate change hinges on understanding these variations.

Linking these variations to the bacterial communities in milk, the research investigates how high temperatures impact milk output, fat, protein, and casein content. This paves the path for focused techniques for controlling heat stress and guaranteeing premium milk output.

Beyond Animal Welfare: The Economic and Quality Toll of Heat Stress on Dairy Farming

Dairy cow heat stress affects milk quality and farmers’ way of life. High temperatures decrease milk quality and lower feed intake and output, posing major financial problems. Its impact on milk bacteria is an often disregarded factor that might aggravate milk deterioration and mastitis, an expensive mammary gland illness.

Though it’s crucial, little study has been done on how heat stress changes the bacteria population in milk. Shelf life, safety, and nutritional quality depend on milk bacteria. Changes in these bacteria may cause mastitis and more spoiling, influencing animal health and farm economics.

Little was known historically about the variations in milk microbiota across dairy cow breeds in response to heat stress. This information vacuum has hampered efforts to create plans of action to counteract the negative consequences of heat stress.

The research findings have the potential to revolutionize dairy farming. By enabling farmers to use breed-specific techniques, they could maximize milk output during heat waves. Moreover, this research could guide breeding initiatives to enhance cows’ thermal stress tolerance, leading to more sustainable and profitable dairy production.

Controlled Thermal Trials: A Methodical Approach to Investigate Heat Stress Impact

The research strategy was meticulously designed to probe the complex impacts of heat stress on the milk microbiota of Holsteins and Brown Swiss cows. This innovative study was conducted in cooperation with the University of Milan, the University of Bari, and the Institute of Agricultural Biology and Biotechnology housed at the National Study Council of Italy in summer 2022.

Set in a Southern Italian commercial dairy farm, the experiment controlled heat conditions by turning off the barn’s cooling system for four days and then reactivating it. Data loggers placed at the cows’ head height correctly tracked temperature and humidity, thereby nearly replacing their natural surroundings.

Reared under the same conditions, forty cows—equally split between 20 Holsteins and 20 Brown Swiss—were Along with a thorough investigation of the milk bacteria under both heat stress and standard settings, researchers gathered milk samples during morning and afternoon milking sessions to examine the effect of heat stress on production metrics including milk output, fat, protein, and casein content.

Heat Stress Divergently Influences Milk Composition in Holsteins and Brown Swiss Cows 

However, heat stress affected milk composition in Holsteins and Brown Swiss cows in various ways. Protein, casein, milk output, fat-corrected milk, and energy-corrected milk all dropped more noticeably in Holsteins. While Holsteins’ lactose content was constant, brown Swiss cows showed a slight rise in lactose levels. During the heatwave, both breeds had lowered saturated fatty acids; monosaturated and unsaturated fatty acids were somewhat constant. These findings underline the different degrees of heat stress sensitivity across the breeds; changes in milk content more impact Holsteins.

The Intricate Interplay Between Heat Stress and Milk Microbiota 

The milk microbiota of dairy cows is substantially affected by heat stress; Brown Swiss milk shows more richness under heat than Holstein milk. In both types, bacterial species, including Streptococcus, Enterococcus, Chryseobacterium, and Lactococcus, flourish during heat waves. However, Brown Swiss cows show an increase, suggesting a more flexible microbiota; Holsteins show decreased OTU abundance, indicating less bacterial diversity.

Prevotella 9 also behaves differently; it reduces in Holsteins but increases in Brown Swiss, therefore underlining the different microbial resistance of the breeds to heat stress. Reflecting on their physiological and genetic responses to environmental stresses, this study emphasizes how Holsteins and Brown Swiss produce milk differently under heat stress and harbor distinct microbial communities. This innovative research clarifies the intricate biology behind dairy production and its sensitivity to environmental problems.

Heat Stress Alters Milk Microbiota with Far-reaching Consequences for Dairy Quality and Herd Health

The research shows that heat stress affects the milk microbiome of Holstein and Brown Swiss cows differently, elevating certain bacteria like Streptococcus and Lactococcus. For dairy farming, these developments are vital. While rising Lactococcus levels might cause greater milk fermentation and spoiling, therefore influencing milk quality and shelf-life, certain Streptococcus species are associated with a higher risk of mastitis.

The Bottom Line

The results of our innovative study underscore the urgent need for breed-specific heat stress research. The maintenance of milk quality and herd health is contingent on understanding how different cow breeds respond, particularly as climate change leads to more frequent heat waves. This study calls for management techniques tailored to each breed’s physiological and microbiological characteristics, emphasizing the need for immediate action.

The study also highlights fresh research prospects on how mammary glands respond to heat stress, influencing milk output and quality. Constant research might result in creative ideas to reduce heat stress effects and, hence, support the sustainability and production of the dairy sector.

Key Takeaways:

  • Heat stress affects Holsteins and Brown Swiss dairy cows differently, influencing their milk microbiota and production parameters.
  • Holstein cows show a more pronounced decline in protein, casein, milk yield, fat-corrected milk, and energy-corrected milk under heat stress compared to Brown Swiss cows.
  • Brown Swiss cows exhibit a richer milk microbiota during heat stress, while Holsteins have a richer microbiota under normal thermal conditions.
  • Heat stress alters the abundance of over 100 types of bacteria, including Enterococcus, Lactococcus, and Streptococcus, which can impact milk spoilage and mastitis risk.
  • The study underscores the better thermal regulation capabilities of Brown Swiss cows, with less degradation in milk quality metrics.
  • Future research aims to delve deeper into how mammary glands adapt to heat stress and the subsequent effects on milk production and quality.

Summary: 

A 2022 study in Italy found that heat stress significantly affects milk composition in Holsteins and Brown Swiss cows, affecting animal welfare, shelf life, and farm economics. The study revealed that heat stress changes the bacteria population in milk, potentially leading to mastitis and spoilage. The research could revolutionize dairy farming by enabling farmers to use breed-specific techniques to maximize milk output during heat waves and guide breeding initiatives to enhance cows’ thermal stress tolerance. The controlled thermal trials involved turning off the barn’s cooling system for four days and then reactivating it. The results showed that Brown Swiss milk showed more richness under heat, while Holsteins showed decreased OTU abundance, indicating less bacterial diversity. Prevotella 9 behaved differently in Holsteins but increased in Brown Swiss, underlining the different microbial resistance of the breeds to heat stress.

The Investor Era: How Section 46 Revolutionized Dairy Cattle Breeding

Discover how Section 46 transformed dairy investments and revitalized rural economies. Curious about the hidden gold rush that reshaped the dairy industry? Read on.

Few legislative actions have transformed agriculture as profoundly as Section 46 of the Internal Revenue Code. Enacted quietly in 1968, this amendment revolutionized the dairy cattle breeding industry, unlocking economic opportunities for savvy investors. Section 46 became a financial key to a realm of economic potential. 

Once-abandoned dairy farms sprang back to life. New barns emerged, and rural economies thrived with significant urban investment seeking tax shelters. This legislation ignited a fierce competition among breeding operations for affluent investors’ dollars. 

Investment elevated dairy breeding standards. Successful firms, marked by Grand Championships and superior breeds, attracted capital. The ripple effects revitalized local economies, spreading financial benefits across rural communities. The era of Section 46 stands as a dynamic period in dairy cattle breeding history.

Section 46: The Unintended Catalyst Transforming Dairy Breeding 

Section 46 of the Internal Revenue Code did not improve dairy cattle or change breeding patterns. It was a tax shelter for wealthy taxpayers but injected money into the rural economy. The legislation introduced the investment purchase credit, a tax write-off that let taxpayers offset the costs of investment in livestock against personal income. Participants could buy a beef or dairy animal with a nominal down payment and a promissory note to pay the balance over three years. 

Accountants and lawyers, mostly from New York City, quickly seized this opportunity. They bought and rehabilitated abandoned dairy farms, building barns, fences, and pastures. They then bought Holsteins and created breeding programs. The competition for investor dollars was intense, making investment firms’ track records critically important. Prices for top-tier Holsteins, especially those with show ring capabilities, skyrocketed. 

The activity stimulated by Section 46 was overwhelmingly positive. The substantial sums paid to farmers trickled down to farm equipment dealers, feed mills, car vendors, and appliance shops, creating new prosperity for rural communities. Every million dollars invested generated even more.  Section 46 catalyzed the most significant economic activity in Holstein’s history. 

From Humble Beginnings to Industry Leadership: The Remarkable Rise of John Sullivan and Ledgefield Associates 

By 1974, Ledgefield Associates had made a significant impact as major buyers in the dairy cattle market, purchasing top-tier cattle across the United States and Canada. Their headquarters was at Glenn Tripp’s Farm, a mile west of Batavia, New York. 

John Sullivan was a pivotal figure behind both Erinwood Farms and Ledgefield Associates. Based in Pavilion, New York, Sullivan owned Sullivan-owned Agri-Systems and Erinwood Holsteins and held a stake in Ledgefield Associates. 

Sullivan’s journey began on his family farm in Holcomb, New York. He pursued animal husbandry and agricultural economics at Cornell University, graduating in 1962. He excelled in intercollegiate judging contests, securing two wins in New York. After graduation, he worked at First Trust and Deposit Company in Syracuse, rising to assistant manager in the farm loan department. 1965, he left to establish Agri-Systems Inc., eventually becoming a national sales leader by 1974. 

His foray into Holsteins began in 1961; by 1968, he had purchased his first Holstein. He continued to build his Erinwood herd, culminating in the Erinwood-Trippacres sale in 1973, where 66 head averaged $2,074.00. Sullivan learned that showing cows without pedigrees was a poor investment, so he required each cow’s dam to be Excellent or have several generations of Very good. 

In 1972, Sullivan and Stuart Hutchins of Paris, Ontario, bought Wintercrest Sunlea for $20,000.00. By May 1973, Sullivan purchased Hutchins’ 40-head herd, averaging $6,000.00 per head. Erinwood/Leadfield relocated their herd to a new barn in LeRoy, New York, in 1974, making significant acquisitions, including the prestigious Craigo family from Skagvale Farms. 

The Erinwood team owned numerous notable Holsteins in the mid-1970s, including the high-priced Glamour cow, purchased for $74,000.00 and sold pregnant to Osborndale Ivanhoe. Her calf, Allendairy Glamourous Ivy, became a noteworthy addition to the herd. 

The Erinwood organization held two Royal Erinwood Sales, with the inaugural sale in 1975 setting a record average of $19,304.00 per head. The top animal, Erinwood Pre Eminent, sold for $110,000.00. With his Irish charm and promotional skills, John Sullivan expertly orchestrated these events. 

At the 1976 sale, Hillranch Fond Matt Jean fetched $48,000.00, purchased by George Morgan. One notable sale included a half-interest in Cass-Ridge Jewel Pat and 11 offspring for $275,000.00. 

Md-Maple Lawn Marquis Glamour and her famed daughter Ivy significantly impacted the breed. Ivy’s son, Leadfield Columbus, became the highest P.D.M. bull in 1983. Another prominent bull from Erinwood, Leadfield Prestar, sired multiple champions, including Hanson Prestar Monalisa, a Central National grand champion

Erinwood and Sullivan left an enduring legacy on the dairy cattle industry, driven by strategic investments and unparalleled expertise in Holstein breeding.

Dreamstreet Holsteins: Revolutionizing Dairy Breeding with Unmatched Quality and Vision 

The first investor program exploiting Section 46 was initiated by Arthur Pulitzer, an accountant from Suffern, New York, who stationed his cattle at a Cherry Valley farm. After a successful trial, Pulitzer shared his idea with fellow C.P.A.s Jerry Bernstein and Robert Friedman. 

Seeking expertise, Bernstein contacted Leonard Baird, then president of the New York State Holstein Association, who recommended Peter Heffering. Co-owning the renowned Hanover Hill herd in Amenia, New York, Heffering became a key figure. In August 1972, Bernstein and Friedman visited Heffering and proposed a joint venture. 

Though interested, Heffering had a herd dispersal sale imminent, so Bernstein and Friedman returned to New York City. Subsequently, Heffering learned that Jim Repard, a cautious Holstein trader, had declined Bernstein and Friedman’s offer. Heffering then approached Bernstein again. 

By 1974, Bernstein, Friedman, and Heffering launched a pilot project with twelve investor programs, each involving two Hanover Hill cows. Despite the success, the Black Watch Angus Farm scandal, with its fraudulent livestock investments, cast a shadow. Nevertheless, it did not hinder their growth. 

Dreamstreet Holsteins, Inc., founded by George Morgan, epitomized the investor era. Morgan, a savvy urbanite passionate about Holsteins, transformed the industry. Growing up in Scotch Plains, NJ, with a C.P.A. father and an uncle managing a dairy farm, Morgan spent his childhood surrounded by Holsteins. 

Morgan studied English at Rutgers University and worked on a dairy farm to support his family. Leaving school in 1960, he worked as a herdsman in Bel Air, MD. Soon, he struck out on his own with Osborndale Ivanhoe calves in Warwick, NY, forming a close bond with Albert Buckbee, an expert in dairy cattle. 

In 1965, Morgan bought a farm in Walton, NY. Despite heavy debts, he balanced dairy farming and raising five children, eventually entering the real estate industry in 1969. Within four years, he earned over a million dollars in commissions, selling rural properties to urbanites. 

Despite real estate success, Morgan’s love for Holsteins persisted. The 1973 oil crisis reduced his sales, giving him time to delve into U.S. tax laws like the livestock investment credit. He realized investors could buy cows, receive tax rebates, and benefit from depreciation. Morgan leveraged these insights, forming his first investor group in 1972. 

By 1975, Dreamstreet was a significant player, notably spending $104,800 at the Royal Erinwood Sale. Partnering with C.P.A. George Teichner, they attracted New York City businessmen as clients, forming Dreamstreet Holsteins, Inc. Morgan’s model grouped six farms into “satellites” managed by dedicated teams, expanding to manage 1,200 cows on 18 farms by 1979. 

Internal issues soon surfaced. Morgan and Teichner, both strong personalities, clashed over business direction, particularly non-farming ventures like an ultrasound rat repellent system and machinery dealership advocated by Frank Wood. To resolve these, Morgan and Wood secured a loan to buy out Teichner’s shares. Subsequently, George and Linda Morgan established the “Tyrbach” prefix, naming it after Morgan’s ancestral Welsh farm. Tyrbach comprised three adjoining farms in Walton, covering 500 acres, founded on Puget-Sound cattle bought in 1976.

Mr. and Mrs. George Morgan operated their Holstein herd continuously until March 2008, when they decided to disperse it. Unlike Hanover Hill Farm in Ontario, Dreamstreet often moved animals to maximize investor profits. 

George Morgan excelled with Round Oak Apple Elevation daughters, breeding over 40 Excellent-rated Elevations. Dreamstreet Rorae Pocohontis (EX-93) sold for $530,000 in the 1983 Designer Fashion Sale, establishing an exceptional lineage. 

At Trybach Farm, Morgan bred Trybach Elevation Twinkie (EX-97), the first cow to win grand championships at three National Shows and the Royal Winter Fair in 1986. Twinkie’s dam, Briggskill Hostess Twinkle (VG-87), came from the Briggskill herd, bought by Morgan for an average of $1,000 per cow. After selling Dreamstreet in 1979, Morgan retained Twinkle and bred her to Elevation, resulting in Twinkie in December 1981. 

Twinkie was nominated for All-American honors as a calf in 1982 and was sold for $10,000. Morgan saw Twinkie’s potential and, after securing a $60,000 loan, partnered with Peter Heffering to purchase her for $47,000. A year later, Twinkie achieved grand champion status at all three U.S. National Shows in the same year; Hanover Hill subsequently bought Morgan’s interest in 1983. 

Another notable cow was Mity-Fine Matt Misty (EX), part of two Reserve All-Americans gets by No-Na-Me Fond Matt. Morgan acquired Misty as a 4-year-old in 1975 for $25,000 and sold her two months later to Edwin R. Gould and Bryce Metcalf. Misty eventually produced G-Metcaif Valiant Mist (EX-2E-94), valued at around a million dollars. 

Morgan was always ready to sell a cow for $100,000, famously saying, “God makes cows every day.” 

John Lennon’s investment in Dreamstreet led to the purchase of Spring Farm Fond Rose for $56,000, later sold for $250,000 in the 1980 Summer Dreams by Dreamstreet Sale. 

In 1976, Frank Wood, an Albany tax attorney, joined Morgan and Teichner to plan a Holstein export business. By October 1979, Morgan sold his stake in Dreamstreet to Wood, who became the new president, with James Bell following in leadership. 

Under Wood, Dreamstreet thrived, purchasing top-tier show cows and entire herds with prices reaching the quarter-million-dollar range. In the early 1980s, Dreamstreet boasted one of North America’s premier show herds, which washighlighted in 1983 when they showcased grand and reserve grand champions at the Central National Show. 

Dreamstreet’s roster included champions like Milleroale Ultimate Rosalynn (EX), Campbell-Hollow Ultimate Kate (EX), and Howard-Home Valiant Eva (EX). Among their prized cows was Kriegeroue PB Cosima, a Bootmaker daughter whose son, Dreamstreet Commander, became Italy’s most used Holstein bull of 1989. 

A notable acquisition was the Agro Acres herd from Hamilton, Ontario. Frank Wood discussed the potential investment with Glenn Tripp, leading to a purchase just above $1 million, including the illustrious Sheffield Climax Pansy (EX) family. 

Dreamstreet’s headquarters was a modest white cottage in Walton, where influential figures like Frank Wood and Buddy Fleming conducted business. Fleming, originally a cattle clipper, had rapidly ascended to Vice-President of cattle operations.

Throughout this period, unsettling rumors about Dreamstreet’s financial instability and an I.R.S. investigation emerged. The artificial insemination industry exhibited scant interest in Dreamstreet’s bulls; they found it challenging to sell females and lacked a robust heifer-raising program—a critical issue since heifers represent the primary income source in this sector. Allegedly, calves were even dying in the hutches. 

Customers such as Sites, Brophy, and Sands, who had acquired cattle from Dreamstreet, chose to leave and initiate their operations, further underscoring the issues at Dreamstreet. 

Ultimately, while the I.R.S. exonerated Dreamstreet, public scrutiny precipitated tax code changes that abolished many tax shelters. Dreamstreet attempted a pivot by venturing into the foreign embryo market. Still, the 1987 stock market crash drove the enterprise into receivership. 

By 1989, a new entity, New Dreamstreet Corporation, had emerged. However, in May 1990, 4,000 heads of the former Dreamstreet herd were sold to Masstock Montezuma, Inc., signaling the definitive end of Dreamstreet. 

An era had indeed concluded; Dreamstreet indeed possessed some extraordinary cows.

The Evolution of Hilltop-Hanover Farm: From Guernseys to Elite Holsteins

The Hilltop-Hanover Farm at Yorktown Heights, N.Y., was once home to the Hanover Hill Guernsey herd, managed by Dave Younger and owned by Henry Christal, who also had a Holstein farm in Amenia, N.Y. In 1968, Peter Heffering and Ken Trevena rented the Amenia farm. They developed the first Hanover Hill Holstein herd, with Christal’s permission to use the Hanover Hill name. 

When a Wall Street group purchased the Yorktown Heights farm from the Christal estate, they named it Hilltop-Hanover and engaged Younger as manager in 1975. Younger, born on September 23, 1917, in Nebraska, had previously managed draft horses and worked for Mrs. Max Dreyfuss, who introduced him to dairy farming during WWII. In 1945, he helped Christal set up Hanover Hill Guernseys, quickly turning it into a recognized herd. 

1969, with Christal’s encouragement and financial assistance, Younger and Heffering started Hanover Hill Sales & Service. This influential sales management business succeeded significantly with its Designer Fashion Sales series. The first sale in 1975 introduced Younger to Wall Street stockbrokers, who later partnered to form Hilltop-Hanover Farm in 1977. Younger managed 40 selected cows from Dreamstreet Holsteins’ programs and additional purchases. 

Hilltop-Hanover’s classification in 1977 featured 41 heads averaging 88.7 points and a B.A.A. of 109.8%, including 20 Excellents. The herd included prestigious cows like Burley Bootmaker Valid (EX) and Hillranch Fond Matt Jean (EX). 

By the early 1990s, over 50 Excellent cows had been bred and developed at Hilltop-Hanover. Despite tax changes eliminating the investment credit, the farm continued to thrive. Younger emphasized that investor confidence was maintained by caring for cattle, particularly calves, promoting investor-owned animals, and generating occasional income. 

The Hilltop-Hanover partial dispersal on October 22, 1990, was the highest-grossing Holstein sale of the year, totaling $1,792,450.00 on 180 head. The highest-selling animal was Hilltop-Hanover-B Bellerina, which fetched $210,000.00. The final dispersal on December 9, 1991, in Amery, Wisconsin, totaled $579,925.00 on 77 head, with the high seller, Hilltop-Hanover-B LM Diedra, being sold for $57,000.00 to Larry Jerome of Jerland Holsteins.

The Troubled Legacy of Jack Stookey: Ambition, Success, and Downfall 

He had a lovely mom and dad, hardworking folks from dawn to dusk. Emra and Mary Stookey, their names were. Jack Stookey was the youngest of three sons. Dr. George Stookey, the oldest, graduated from Indiana University, received a master’s in preventive dentistry in 1962, and a doctorate in dental science in 1971. He joined the Indiana University School of Dentistry as an assistant professor in 1964. He was promoted to associate professor in 1973 and full professorship in 1978. As an avid researcher, his primary interests were fluoride pharmacology and the prevention of dental caries. He held at least twenty patents. Dr. Stookey discovered Fluoristan, the substance in toothpaste that prevents cavities. He sold his patent to Procter & Gamble, profiting from royalties. 

At the end of the day, when Jack screwed up, Dr. George stepped in. It had to happen well. In Mary Stookey’s eyes, Jack could do no wrong. He was her golden-haired boy and the candy kid. When his first wife didn’t meet Mary’s expectations, she promoted the dissolution of the marriage. Jack followed Mom, dumped their first wife, and then married Darla. He got it right that time. She straightened him out. When Darla entered the picture, Jack had started to drift. Until then, he had enjoyed a distinguished career. He graduated high school as a track and field star. He won a scholarship to Wayland Baptist University, setting state athletic records. Returning to Leesburg in 1968, he indulged his passion for automobile racing, designing and building his cars and driving them in races. It was a dangerous way to make a living. His mother protested, and Darla put her foot down, telling him to get into something safer and steadier. Jack quit car racing and returned to the home farm, a 1,500-acre showplace built by Emra and Mary, home to a herd of Holsteins, one of the best in the state. By 1980, there were 31 Excellent and 33 Very Good females. 

Emra and Jack sold the herd at its peak. A farm auction averaged $4,381.00 on 124 head, with a top price of $21,000.00 for VT-Pond-View Bootmaker Lassi (EX). Six heads sold for five-figure prices. The dispersal was prompted by Jack’s newfound vision to start an investor herd, assembling the best Holsteins North America had to offer. He quickly entered the investor business, receiving money by the wheelbarrow full. The investment purchase credit appealed to individuals earning $500,000.00 a year and upwards. Around Indianapolis, there were plenty in that category. The Stookey name spread beyond Indiana; soon, investors from California, Florida, and Georgia were sending money. 

The first cow Jack bought was Georgian Quality Pat, one of his best, a significant quality Ultimate daughter who could win at shows. Jack bought other remarkable cows besides Pat, incorporating them into investor packages and promoting them in the show ring. His best year was 1983 when he took home the premier exhibitor banner at the Central National Show and nearly the same at the Eastern and Western Nationals. Attracted to the red and white breed, he bought Continental Scarlet-Red (EX) after she won the grand championship at the Royal Winter Fair in 1982. Scarlet was the only cow to defeat Brookview Tony Charity at the Royal. 

Another special individual was Nandette TT Speckle-Red (EX), the Triple Threat daughter bought from David Brown. Jack could accurately state he owned two of the best red and whites of the 1980s. Other notable cows owned by Jack wore black and white coats, such as Raylore Citamatt Ali, All-American Junior 2-Year-Old, C Til-El Kim Second Sheik, Reserve All-American Senior 2-Year-Old, and C Clarene Citamatt Joan, Reserve All-American 3-Year-Old. 

Then the I.R.S. came calling. They disapproved of cattle investment tax shelters and were auditing many in the early 1980s. There was a target on Jack’s back. The I.R.S. disallowed many of his tax loss claims, demanding six-figure back taxes. This crisis hit as the flow of investor funds slowed, and his herd wasn’t generating much revenue. Incidents painted a dire picture: In winter 1985, unable to pay his help, Jack had his men load a trailer with bull calves—planned to be sold for breeding purposes—and take them to the slaughterhouse, including three sons of Continental Scarlet by Roybrook Telstar. When Jack broke, neighbors Mr. Van Forest and his son, who cared for 80 heifers, also lost their farm. 

A blizzard in 1985 buried 100 Stookey calf hutches in the snow; all the calves suffocated, including 18 by Enhancer out of Scarlet. Rumors surfaced: Jack bought high-priced cows in Canada, stopped at the border when checks bounced, and a disgruntled investor allegedly dynamited his porch. Such scuttlebutt turned Jack into a pariah; legitimate breeders shunned him, some calling him a shyster. An Indiana breeder recalled Jack as “a selling Jesse,” capable of selling anything. 

The I.R.S. filed a lien for back taxes, prompting Jack to file for bankruptcy. The bankruptcy trustee took possession of Jack’s assets, causing legal issues as Jack had only made the first payment on many cattle. Breeders claimed their animals still belonged to them, but the trustee claimed priority over unpaid vendors’ liens. The court upheld the trustee’s claim. 

Dr. G.W. Snider of Goshen, Indiana, settled a sizeable unpaid vet bill by taking Stookey Fagin Scarlet, Scarlet’s Coldsprings Elevation Fagin daughter, the first red and white cow to make 50,000 lbs. of milk and classify 93 points. Lamenting the waste of superior genetics, Louis Prange of Elm Park Farms made a deal with the trustee, taking some cows on a flush program and agreeing to split sale proceeds. One donor was Nandette TT Speckle. Flushed to Blackstar, she produced Stookey Elm PM-K Blackrose. 

Jack’s splash in the investor business lasted about four years, from 1980 to 1984, peaking in 1983-1984. The investment credit provision’s repeal in the Tax Reform Act of 1986 wasn’t Jack’s downfall; it was Jack himself. Convicted of fraud and embezzlement, he served his sentence on weekends. The convictions and bankruptcy ended his business. Jack relocated to Tulsa, Oklahoma, joining a firm that sold U.S. currency to foreign investors. 

Dr. George Stookey saved the family farm, taking their mother, Mary, to live with him. Jack maintained ownership of the Leesburg farm, attempting to sell it to Randy Frasier for his Elmvue herd. Frasier invested $85,000.00 in fixing the farm buildings but learned Jack didn’t have the right to sell it, leaving Indiana frustrated. 

In 2004, an Indiana farm paper reported Jack’s death by suicide. Rumors included involvement with Colombian drug traffickers. To verify, I contacted Glenn Tripp, Jack’s leading man during peak years, who attended the funeral. Tripp revealed that the I.R.S.’s persistent pursuit and a $1.5 million tax arrears claim led Jack to take his life, driving down a back road and shooting himself. 

In the beyond, Jack can take credit for breeding arguably the two best animals from the investor era: Stookey Elm Park Blackrose and Stookey Fagin Scarlet, names well-known in the Holstein community.

The Bottom Line

Section 46 of the Internal Revenue Code revolutionized the dairy industry. Offering a tax shelter attracted wealthy investors and injected funds into rural economies. This led to revitalized farms, updated facilities, and quality livestock, especially Holsteins. The intense competition among investment firms marked this period with unparalleled prosperity and innovation in the dairy sector. Though meant as a financial incentive, the legislation’s secondary effects fostered economic growth and higher standards in dairy farming. The legacy of Section 46 highlights how legislative changes can transform an industry, inspiring contemporary Holstein breeders and dairy farmers.

Key Takeaways:

  • Quiet Introduction: Section 46 was enacted without fanfare or widespread attention, largely unacknowledged by the agricultural press and urban populations.
  • Targeted Benefits: The legislation primarily served as a tax shelter for wealthy taxpayers, offering significant tax credits for investments in livestock.
  • Economic Boost: Despite its primary intent, Section 46 indirectly injected substantial funds into the rural economy, benefiting various sectors including farm equipment dealers and feed mills.
  • Opportunity Seized: Financial professionals, particularly in New York City, quickly capitalized on the legislation, creating investment businesses and revitalizing abandoned dairy farms to accommodate investors.
  • Intense Competition: The fight for investor dollars led to fierce competition, skyrocketing the prices of elite Holstein cattle with show ring capabilities.


Summary: Section 46 of the Internal Revenue Code, enacted in 1968, revolutionized the dairy cattle breeding industry by providing economic opportunities for investors. The legislation introduced the investment purchase credit, allowing taxpayers to offset the costs of investment in livestock against personal income. This allowed accountants and lawyers from New York City to buy and rehabilitate abandoned dairy farms, build barns, fences, and pastures, and buy Holsteins and create breeding programs. The competition for investor dollars was intense, making investment firms’ track records crucial. The activity stimulated by Section 46 was overwhelmingly positive, with substantial sums paid to farmers trickling down to farm equipment dealers, feed mills, car vendors, and appliance shops, creating new prosperity for rural communities. John Sullivan, a pivotal figure behind Erinwood Farms and Ledgefield Associates, made a significant impact as major buyers in the dairy cattle market, purchasing top-tier cattle across the United States and Canada. Dreamstreet Holsteins, Inc., was founded by George Morgan in 1972, focusing on U.S. tax laws and the livestock investment credit. The Hilltop-Hanover Farm at Yorktown Heights, N.Y., was once home to the Hanover Hill Guernsey herd, managed by Dave Younger and owned by Henry Christal.

Discover the Unique Nutritional Needs of Jersey Cows

Discover how to maximize efficiency and health in Jersey cattle. Learn about their unique nutritional needs and how to address them effectively.

Holsteins are known for high milk volume, while Jerseys shine for quality and adaptability. Their smaller size and unique traits make them valuable assets. However, they have distinct nutritional needs that require careful attention to optimize health and efficiency.  Jerseys excel in producing nutrient-rich milk and are incredibly efficient in feed conversion and land use. Addressing their specific requirements can boost milk quality , which refers to the composition and characteristics of the milk, and herd health, making them essential for sustainable and profitable dairy farming.

Jersey Milk: Nutrient-rich, Flavorful, and Versatile for Health and Culinary Applications

When it comes to dairy, the nutritional quality of milk significantly impacts consumers. Jersey milk, boasting higher protein, milkfat, and calcium than Holstein milk, is a standout choice. Its increased protein levels aid muscle maintenance and repair, crucial for active and aging individuals. A higher milkfat percentage promotes the absorption of fat-soluble vitamins essential for overall health. Additionally, elevated calcium content strengthens bones and teeth, making Jersey milk ideal for boosting family nutrition. This superior quality of Jersey milk instills confidence in dairy professionals about the value they provide to consumers. 

“The nutrient density of Jersey milk provides essential nutrients in higher quantities and enhances its culinary versatility. Chefs and home cooks prefer Jersey milk for its rich texture and flavor, which can elevate both sweet and savory dishes.”

Jerseys: Small Stature, Significant Advantages for Dairy Operations 

Jerseys, with their smaller size than Holsteins, offer unique advantages to dairy operations. Their compact stature means they consume less feed and optimize barn space. Despite their smaller size, Jerseys excel in converting feed to milk with high protein, milkfat, and calcium levels. This unique trait empowers dairy farmers to maximize their resources and enhance their herd’s productivity. 

Jerseys also maintain a higher dry matter intake (DMI) after calving, which is crucial for meeting energy needs during lactation and reducing metabolic disease risks. Their increased chewing improves rumen stability and fiber digestibility, making them more efficient feed converters than other breeds.

Scientific Validation: Jerseys’ Superior Feed Conversion Efficiency 

Scientific research demonstrates that Jerseys are significantly more efficient than Holsteins at converting feed into milk components. Studies show that when producing the same amount of protein, milkfat, and other solids, Jerseys need 32% less water, use 11% less land, and consume 21% less fossil fuels. This efficiency highlights their minimal environmental impact

Moreover, Jerseys extract and utilize energy from their diets more effectively, leading to higher nutrient levels in their milk. A glass of Jersey milk contains 18% more protein, 29% more milkfat, and 20% more calcium than Holstein milk. This nutrient density underscores Jersey milk’s superior quality and enhances the breed’s value in the dairy industry.

Key Nutritional and Health Differentiations: Feed Intake, Energy Metabolism, and Overall Health 

When examining Jersey’s dietary and health needs, three areas stand out: feed intake and digestion, energy metabolism, and health. 

Regarding feed intake and digestion, Jerseys maintain a higher DMI post-calving relative to their body weight. This, alongside spending more time chewing, supports a stable rumen environment, enhancing fiber digestibility and feed conversion efficiency. 

In terms of energy metabolism, Jerseys extract more energy from their diet. Energy metabolism refers to the chemical reactions in the body that convert food into energy. Efficient energy metabolism is crucial for cow health and milk production, as it ensures that the cow’s energy needs are met. Jerseys’ ability to extract more energy from their diet means they require fewer resources than Holsteins, making them more environmentally sustainable. Their milk is richer in protein, milk fat, and calcium. 

Regarding health, Jerseys’ smaller size and robust hooves reduce lameness and disease risks. Their higher rumen pH offers better resilience against acidosis. However, fewer vitamin D receptors in their gut increase their risk for milk fever, necessitating careful DCAD management. 

Another critical difference is Jersey’s faster maturity rate, which increases their risk of becoming overweight. Effective strategies include housing them with older Holsteins to better match their nutritional needs and promote healthy growth.

Health Advantages: Why Jerseys Outshine Other Breeds in Dairy Farming 

Jerseys boast substantial health benefits, enhancing their appeal to dairy farmers. Their tiny, hard black hooves produce fewer lameness issues, like hairy heel warts, common among larger breeds. This durability ensures Jerseys are productive, reducing mobility issues and associated treatment costs. 

Additionally, Jerseys maintain a higher rumen pH, granting them better tolerance and quicker recovery from acidosis. This trait helps stabilize digestive health during stressful periods like calving, ensuring high feed efficiency and milk production without frequent digestive upsets. 

However, Jerseys are more susceptible to milk fever due to fewer vitamin D receptors in the gut, making them three times more likely to experience this condition than Holsteins. Milk fever, also known as hypocalcemia, is a metabolic disorder that occurs when the cow’s blood calcium levels drop rapidly after calving. It can lead to muscle weakness, reduced feed intake, and even death if not managed properly. 

Managing this requires proactive measures like monitoring dietary cation-anion difference (DCAD) and calcium mobilization strategies. Regular urine pH checks can help adjust prepartum rations. When current rations fall short, adding anionic salts can effectively prevent milk fever, safeguarding Jersey cow health and productivity.

Optimizing Health and Productivity through DCAD Monitoring and Glucose Enhancement in Jerseys 

To manage Jerseys effectively, it is crucial to monitor and adjust the dietary cation-anion difference (DCAD) and enhance glucose production. These strategies will help mitigate the risks of milk fever while supporting overall energy balance and immune function. 

  • Jerseys maintain higher dry matter intake (DMI) post-calving, aiding in rumen health and feed efficiency.
  • They are efficient feed converters, extracting more energy from smaller absolute feed intake.
  • Jersey milk is nutritionally superior, with higher protein, milkfat, and calcium than Holstein milk.
  • Jerseys mature faster, requiring careful feeding strategies to avoid overweight issues; housing with older Holsteins can help.
  • Jerseys have healthier hooves and higher rumen pH, reducing lameness and acidosis risks.
  • Monitor DCAD status closely to prevent milk fever, utilizing calcium mobilization strategies as needed.
  • Enhancing glucose production can mitigate negative energy balance and support immune function.
  • Breed-specific research is essential for optimizing Jerseys’ health and productivity.

First, consistently measure your cows’ urine pH, aiming for levels between 6.2 and 6.8. If current rations don’t achieve these levels, add anionic salts to the diet to improve calcium mobilization and prevent milk fever. Maintaining optimal DCAD is essential for Jersey’s health during its transition period. 

Enhancing glucose production is vital to counteract the negative energy balance seen postpartum. Increase the energy density of rations by using highly digestible forages and grains, and consider glucose precursors like propylene glycol or glycerol. These can be administered postpartum to address the energy gap, supporting energy reserves and immune function. 

Implementing these strategies requires careful observation and flexibility. Regular monitoring and timely dietary adjustments will help keep Jersey herds healthy and productive, meeting the demanding targets of modern dairy operations.

The Bottom Line
