Friday, December 6th, 2024

Who gets to decide the future of dairy breeding? Understand the challenges and opportunities in shaping tomorrow’s selection programs.

Envision a future where dairy farming is revolutionized by precision and efficiency, with every cow’s genetic makeup optimized for maximum yield and health. This future, driven by the powerful genetic selection tool, has already begun to transform dairy breeding. It has doubled the rate of genetic improvements and refined valuable livestock traits. As we step into this scientific era, we must ponder: ‘What are we breeding for, and who truly makes these decisions?’ The answers to these questions hold the key to the future of dairy farming, influencing economic viability and ethical responsibility.

From Cows to Code: The Genetic Revolution in Dairy Breeding 

Significant scientific breakthroughs and practical advancements have marked the evolution of dairy breeding programs, each contributing to the enhanced genetic potential of livestock populations. Initially, genetic selection laid the groundwork for these developments. Farmers and breeders relied heavily on observable traits such as milk production, fat content, and pedigree records to make informed breeding decisions. This form of traditional selective breeding focused on optimizing certain economic traits, primarily targeting yield improvements. 

However, as scientific understanding evolved, so did the techniques used in breeding programs. The mid-to-late 20th century witnessed a pivotal shift with the introduction of computed selection indices. These indices allowed for a more refined approach by integrating multiple traits into a singular measure of breeding value. Yet, progress during this period was still relatively slow, constrained by the time-intensive nature of gathering and interpreting phenotypic data. 

The transition to genomic selection marked a revolutionary phase in dairy breeding. By focusing on an animal’s DNA, breeders began to predict breeding values with greater precision and much faster. This leap was facilitated by advancements in genomic technologies, which allowed for the high-throughput sequencing of cattle genomes. Genomic selection bypassed many limitations of the traditional methods, significantly shortening the generation interval and doubling the rate of genetic gain in some livestock populations. As a result, dairy herds saw improvements not only in productivity but also in traits related to health, fertility, and longevity. 

These advancements underscore the significant role that genetic and genomic selections have played in enhancing the quality and efficiency of dairy livestock. They have transformed breeding programs from artful practice to sophisticated science, propelling the industry forward and setting the stage for future innovations that promise even more significant gains. 

The Power Players Behind Dairy Genetics: Steering the Future of American Dairy Farming

The intricate world of dairy farming in the United States is guided by several key participants who influence selection decisions and breeding objectives. At the forefront is the United States Department of Agriculture (USDA), with its Animal Genomics and Improvement Laboratory playing a pivotal role in crafting the indices that shape the future of dairy breeding. This laboratory collaborates with the Council on Dairy Cattle Breeding (CDCB), an essential body that operates the national genetic evaluation system and maintains a comprehensive cooperator database. 

The CDCB’s board is a coalition of representatives from pivotal industry organizations, including the National Dairy Herd Information Association (NDHIA), Dairy Records Processing Centers, the National Association of Animal Breeders, and the Purebred Dairy Cattle Associations (PDCA). These institutions act as conduits for innovation and development in dairy cattle breeding through their valuable input in developing selection criteria and objectives. 

Breeding companies, notably ST, GENEX, and Zoetis, bring a competitive spirit. They publish their indices incorporating standard CDCB evaluations and proprietary traits. Their role extends beyond mere evaluation to actively shaping market demand with innovative selection tools that sometimes lack transparent review, raising questions about their added value or potential marketing motives. 

Dairy farmers, the end-users of these breeding advancements, wield significant influence over these indices through their adoption—or rejection—of the tools. Their perception of the indices’ value, informed by their unique economic and operational environments, can drive the evolution of these tools. While some may adhere to national indices like the net merit dollars (NM$), others might opt for customized solutions that align with their specific production goals, reflecting the diversity within the dairy farming community and their crucial role in shaping the future of dairy breeding. 

Together, these stakeholders form a dynamic network that drives the continual advancement of breeding programs, adapting them to meet modern demands and improving the genetic quality of dairy herds nationwide. Their collaboration ensures that long-standing traditions and innovative advancements shape the future of dairy genetics, making each stakeholder an integral part of this dynamic process. 

The Tug of War in Dairy Genetic Selection: Balancing Economics, Environment, and Innovation

Updating selection indices, like the Net Merit Dollars (NM$) index, involves complexities beyond simple calculations. Each trait within an index holds a specific weight, reflecting its importance based on economic returns and genetic potential. Deciding which traits to include or exclude is a hotbed of debate. Stakeholders ranging from geneticists to dairy farmers must reach a consensus, a task that is far from straightforward. This process involves diverse objectives and perspectives, leading to a challenging consensus-building exercise. 

The economic environment, which can shift abruptly due to fluctuations in market demand or feed costs, directly influences these decisions. Such economic changes can alter the perceived value of traits overnight. For instance, a sudden rise in feed costs might elevate the importance of feed efficiency traits, prompting a reevaluation of their weights in the index. Similarly, environmental factors, including climate-related challenges, dictate the emergence of traits like heat stress tolerance, pressing stakeholders to reconsider their traditional standings in the selection hierarchy. 

The dynamism of genetic advancement and external pressures necessitates frequent reevaluation of indices. Yet, every update involves complex predictions about future conditions and requires balancing between immediate industry needs and long-term genetic improvement goals. As these factors interplay, the task remains a deliberate dance of negotiation, scientific inquiry, and prediction that continuously tests the resilience and adaptability of dairy breeding programs.

Tech-Driven Transformation: From Traditional Farms to Smart Dairies

In the ever-evolving landscape of dairy farming, integrating new technologies holds immense potential to revolutionize data collection and utilization in selection decisions. Sensor-based systems and high-throughput phenotyping are two frontrunners in this technological race. They promise enhanced accuracy and real-time insights that could significantly improve breeding programs, sparking excitement about the future of dairy farming. 

Sensor-based systems are beginning to permeate dairy operations, continuously monitoring farm environments and individual animal health metrics. These technologies enable farmers to gather rich datasets on parameters such as feed intake, movement patterns, and milk composition without constant human supervision. Such detailed information provides a clearer picture of each cow’s performance, which is invaluable for making informed selection and breeding decisions. Real-time data collection means potential issues can be identified and addressed swiftly, potentially reducing health costs and improving overall herd productivity. 

High-throughput phenotyping, on the other hand, expands on traditional methods by allowing the measurement of multiple traits via automated systems. This technology can swiftly and efficiently capture phenotypic data, offering scientists and breeders a broader set of traits to evaluate genetic merit. The scale at which data can be collected through high-throughput phenotyping allows for a more comprehensive understanding of genetic influences on various performance traits, supporting the development of more robust selection indices. 

However, these technologies’ promise comes with challenges. A significant hurdle is the need for more standardization. With numerous proprietary data systems, standardized protocols are urgently needed to ensure data consistency across different systems and farms. Without standardization, data reliability for genetic evaluations remains questionable, potentially undermining the precision of selection decisions. 

Validation is another critical challenge that must be addressed. As innovations continue to emerge, the assumptions upon which they operate need rigorous scientific validation. This ensures that the data collected genuinely reflects biological realities and provides a solid foundation for decision-making. The risk of basing selections on inaccurate or misleading data remains high without validation. 

Furthermore, seamless data integration into existing genetic evaluation systems is not enough. The current infrastructure must evolve to accommodate new data streams effectively. This might involve developing new software tools or altering existing frameworks to handle data’s increased volume and complexity. Ensuring seamless integration requires collaboration across sectors, from tech developers to dairy farmers. It fosters an environment where data can flow unimpeded and be put to its best use. 

Embracing these technologies with careful attention to their associated challenges can lead to significant advancements in dairy breeding programs. By harnessing the power of cutting-edge technology while addressing standardization, validation, and integration issues, the industry can move towards more precise, efficient, and sustainable selection decisions.

Preserving Genetic Diversity: The Unsung Hero in Sustainable Dairy Breeding

One of the critical concerns surrounding dairy cattle breeding today is the potential reduction in genetic diversity that can arise from intense selection pressures and the widespread use of selection indices. The drive to optimize specific traits, such as milk production efficiency or disease resistance, through these indices can inadvertently narrow the genetic pool. This is mainly due to the focus on a limited number of high-performing genotypes, often resulting in the overuse of popular sires with optimal index scores. 

The genetic narrowing risks compromising the long-term resilience and adaptability of cattle populations. When selection is heavily concentrated on specific traits, it may inadvertently cause a decline in genetic variability, reducing the breed’s ability to adapt to changing environments or emerging health threats. Such a focus can lead to inbreeding, where genetic diversity diminishes, leading to potential increases in health issues or reduced fertility, further complicating breeding programs. 

Despite these concerns, strategies can be employed to maintain genetic diversity while still achieving genetic gains. These strategies involve a balanced approach to selection: 

  • Diverse Breeding Strategies: Breeders can implement selection methods emphasizing a broader set of traits rather than just a few high-value characteristics, thus ensuring a diverse gene pool.
  • Use of Genetic Tools: Tools such as genomic selection can be optimized to assess the genetic diversity of potential breeding candidates, discouraging over-reliance on a narrow genetic group.
  • Rotational Breeding Programs: Introducing rotational or cross-breeding programs can enhance genetic diversity by utilizing diverse genetic lines in the breeding process.
  • Conservation Initiatives: Establishing gene banks and conducting regular assessments of genetic diversity within breeding populations can help conserve genetic material that may be useful in the future.
  • Regulatory Oversight: National breeding programs could enforce guidelines that limit the genetic concentration from a few sires, promoting a more even distribution of genetic material.

By implementing these strategies, dairy breeders can work towards a robust genetic framework that supports the immediate economic needs and future adaptability of dairy cattle. This careful management ensures the industry’s sustainability and resilience, safeguarding against the risks posed by genetic uniformity.

The New Frontiers of Dairy Genetics: Embracing Complexity for a Sustainable Future

The landscape of genetic selection in the U.S. dairy sector is poised for significant transformation, steered by technological advancements and evolving farm needs. The future promises an expanded repertoire of traits in selection indices, acknowledging both the economic and environmental challenges of modern dairy farming. The potential inclusion of traits like feed efficiency, resilience to environmental stresses, and even novel health traits will cater to the increasing need for sustainable production practices. While these additions enhance the genetic toolbox, they complicate decision-making due to potential trade-offs between trait reliability and economic impact. 

Moreover, the possibility of breed-specific indices looms large on the horizon. A one-size-fits-all approach becomes increasingly untenable, with varying traits prioritized differently across breeds. Breed-specific indices could provide a more refined picture, allowing for optimized selection that respects each breed’s unique strengths and production environments. While technically challenging, this shift could catalyze more precise breeding strategies, maximizing genetic gains across diverse farming operations. 

Concurrently, the emergence of customized indices tailored to individual farm demands offers a promising avenue for personalized breeding decisions. As farms vary in size, management style, and market focus, a bespoke approach to selection indices would allow producers to align genetic goals with their specific operational and economic contexts. This customization empowers farmers by integrating their unique priorities—whether enhanced milk production, improved animal health, or efficiency gains—within a genetic framework that reflects their singular needs. 

In sum, the future of U.S. selection indices in the dairy industry will likely include a blend of broader trait inclusion, breed-specific customization, and farm-tailored solutions. These adaptations promise to enhance genetic selection’s precision, relevance, and impact, supporting a robust and sustainable dairy sector that meets tomorrow’s dynamic challenges.

Melding Milk and Mother Nature: The Crucial Role of Environment in Dairy Genetics

The landscape of dairy breeding is shifting as the need to incorporate environmental effects into genetic evaluations becomes increasingly apparent. In a rapidly evolving agricultural world, factors affecting performance are not solely genetic. The environment is crucial in shaping breeding programs’ potential and outcomes. This understanding opens new avenues for enhancing selection accuracy and ensuring sustainable dairy farming. 

By considering environmental effects, farmers can gain a more holistic view of how their cows might perform under specific farm conditions. These effects, divided into permanent aspects like geographic location and variable ones such as seasonal changes in feed, help build a comprehensive picture of dairy cow potential. Recognizing that genotype-by-environment interactions can influence traits as much as genetic merit alone allows farmers to tailor breeding strategies to their unique settings. 

The quest to decode these interactions holds promise. As sensors and data collection technologies develop, capturing detailed environmental data becomes feasible. Feeding regimens, housing conditions, and health interventions can be factored into genetic predictions. Such precision in understanding the cow’s interactions with its environment enhances selection accuracy. It can lead to meaningful improvements in health, productivity, and efficiency. 

Moreover, acknowledging these interactions fosters a breeding philosophy sensitive to productivity and sustainability. It supports resilience against climate challenges and encourages practices that align with environmental goals. Ultimately, incorporating this dual focus of genetics and environment in dairy breeding could be the key to a future where dairy farming meets both economic demands and ecological responsibilities.

Data: The Lifeblood of Dairy Genetic Progress 

The flow and integrity of data play a pivotal role in shaping the future of genetic evaluations in the intricate tapestry of dairy breeding. Managing and integrating diverse data sources to create a unified, reliable system offers immense opportunities. 

Firstly, with the advent of sensor-based and innovative farming technologies, data influx has increased exponentially. These technologies promise to harness real-time data, providing an unprecedented view of animal genetics and farm operations. The potential to improve breeding precision, optimize feed efficiency, and enhance animal health through this data is vast. By tapping into this reservoir of information, farmers and researchers can develop more effective breeding strategies that account for genetic potential and environmental variables. 

However, with these opportunities come significant challenges. Key among these is data ownership. Many modern systems store data in proprietary formats, creating data silos and raising questions about who truly owns the data generated on farms. This lack of clarity can lead to data access and use restrictions, which inhibits collaborative research and development efforts. Ensuring farmers have autonomy over their data while respecting the proprietary technologies in use is a delicate balancing act. 

Quality certification also poses a substantial challenge. Unlike traditional data sources with established protocols, many newer technologies operate without standardized validation. This lack of certification can lead to consistency in data quality, making it difficult to ensure accuracy across large, integrated datasets. Organizations like the NDHIA in the United States serve as gatekeepers, ensuring lab measurements are precise and calculations correct, but expanding such oversight to new technologies remains a hurdle. 

National databases are indispensable in supporting genetic evaluations. They act as centralized repositories of validated data, facilitating comprehensive analyses that underpin genetic improvement programs. These databases must be continually updated to incorporate new data types and technologies. They also need robust governance structures to manage data contributions from multiple sources while ensuring privacy and security. 

In conclusion, while considerable opportunities exist to leverage diverse data sources for dairy breeding advancements, addressing ownership dilemmas, achieving data certification, and reinforcing national databases are crucial. These efforts will ensure that genetic evaluations remain reliable, actionable, and beneficial to all stakeholders in the dairy industry.

The Bottom Line

The future of dairy breeding hinges on integrating complex genetic advancements with traditional agricultural wisdom while balancing the economic, environmental, and technological facets that define modern farming. Throughout this examination, we have delved into the mechanisms and challenges underscoring today’s breeding programs—from the evolving role of selection indices to the adoption of technology-driven phenotyping and the delicate dance of maintaining genetic diversity. At the core of these endeavors lies a critical need for a cohesive strategy—one where dairy farmers, scientists, commercial entities, and regulatory bodies work hand in hand to forge paths that benefit the entire industry. 

As we reflect on the pressing themes of accountability, innovation, and sustainability, it becomes evident that genetic evaluations should support individual farms and act as a shared resource, accessible and beneficial to all. Readers are encouraged to ponder the far-reaching consequences of breeding choices, recognizing that while genetics offers unprecedented tools for enhancement, it also demands responsible stewardship. Ultimately, our collective success will be determined by our ability to harmonize data, technology, and practical farming experience, ensuring a prosperous and sustainable future for dairy farming worldwide.

The Evolution of Dairy Cattle Breeding: From Famous Herds to Genomic Giants

Monday, October 14th, 2024

Dive into the history of dairy cattle breeding. How have renowned herds influenced today’s genetics? Uncover their role in modern dairy operations.

Have you ever considered how dairy cow breeding has evolved over the years? It has been an enthralling voyage from the renowned arenas of famous registered herds to the current ‘Genomic Index Age, a pivotal era where genetic giants now rule supreme. In the first part of the twentieth century, renowned herds supported by investor money supplied bulls from high-yielding dams, making them a desirable asset to small dairy producers seeking genetic improvement. Fast forward to today, when genetic evaluations (G.E.) and DNA-based indexing have redefined what it means to have excellent breeding stock. The days of commanding high prices only based on the name of the herd are over. Today, it is all about the science behind genetics for over fifty heritable traits.

Pre-WWII: The Golden Age of Elite Dairy Herds

This was a pivotal period that laid the foundation for the modern dairy breeding industry during this pivotal period. Before World War II, widely recognized dairy herds dominated the dairy breeding business. A herd’s prefix often defines its popularity, not the animals’ genetic merit. Significant investor funds often supported these herds, allowing them to retain high-quality buildings, personnel, and resources. Consequently, they became the preferred supplier for smaller dairy producers looking for high-quality herd bulls.

While these herds were lauded for individual cow’s exceptional milk and butterfat outputs, it is essential to note that their success was not simply due to any genetic improvement. Rigorous management procedures and enhanced nutritional strategies were critical in setting high production records. As a result, these herds made a relatively small genetic contribution to the larger dairy farming community. Their true advantage resided in their operational competence, which smaller farms aspired to replicate by purchasing bulls from these well-known herds. 

Not all animals in these herds were evaluated for performance during this era, and animal marketing trumped genetic improvement. However, the number of purebred registered animals grew in the market share of all dairy cattle.

1945-1960: The Era of Aesthetic Excellence Over Performance 

Between 1945 and 1960, many well-known dairy farms strongly emphasized ‘type’ over productivity. In this context, ‘Type’ refers to the physical appearance of dairy cattle, including body parts, stature/size, and show appeal. The objective was to improve these physical qualities, which often led to cows from these herds receiving showring rewards for their remarkable conformation.

While the emphasis on type resulted in cosmetically improved cows, it did not translate into any significant genetic advancement in milk output. Small dairy producers who depended on bulls from these prominent herds may have produced more attractive cows, but milk yield progress was flat. The need for beauty trumped the necessity for improved functional and yield traits.

New standards were set for ideal type (pictures and models) and yield (M.E.’s and BCA’s) traits during this era. For herds on official milk recording, it was required that all cows in the herd be recorded – a very positive step for genetic comparison procedures and accuracy.  Animal genetic merit started to gain on animal marketing as the primary focus in owning purebreds. Milk producers increased their participation in breed and milk recording programs.

Mid-1960s to 1980: The Great Divide Between Type and Production 

The mid-1960s to 1980 marked a watershed moment in dairy cow breeding, as genetic evaluation information (G.E. became available, especially for productivity traits such as milk output and fat content.

The refusal by the previously dominant display herds to include G.E.’s in their breeding efforts had implications. Their steadfast commitment to type while ensuring animals looked great in the showring resulted in these herds losing significance in genetic progress. And they also lost influence with breed organizations.

Meanwhile, some farmer-breeders saw the promise of accurate young sire sampling programs and accurate genetic indexes and experienced significant increases in herd production. These progressive farmer-breeders’ herds outperformed their type-focused competitors because they utilized production genetic information extensively.

As the breeding business shifted to a more science-driven approach, the gap between show-type herds and those focused on production efficiency grew. Farmer-breeders began to see the importance of using daughter-proven A.I. sires with robust genetic indexes, leaving conventional display herds needing help to retain their prior leadership role. This transition from type to production efficiency marked a significant shift in the industry’s approach to breeding.

During this time, extensive industry-supported research into genetic evaluation procedures and breeding strategies revolutionized the dairy cattle breeding industry. Leadership in genetic improvement started to shift from breeds and prominent herds to artificial insemination organizations. Purebred registered herds on milk recording and type classification programs made moderate genetic progress during this period.

Post-1980: The Revolutionary Impact of Genetic Evaluations

Post-1980, the dairy industry witnessed a revolutionary impact of genetic evaluations. Dairy farmers saw significant advances in the genetic merit of their herds by using assessment tools, including milk recording, type classification, young sire sampling, and elite proven sires. These tools transformed dairy cattle breeding on a monumental scale, leading to profound changes and advancements in the industry, especially for yield traits and mammary systems.

With the advent of genetic research, an expansion in data for new heritable traits, and enhanced genomic evaluation procedures, the dairy cattle breeding industry entered a new era. By the 1990s, the accuracy of genetic assessments had significantly improved, and total merit indexing (TPI, NM$. LPI, JPI, …) became widely used. A.I. sire selectors began to rely heavily on data-driven criteria to find bulls with significant genetic potential. These developments significantly departed from the earlier twentieth-century emphasis on phenotypic features, including type and showring characteristics. The gap in cow productivity widened between show-type herds and production-oriented farms, highlighting the importance of these new tools in driving genetic progress.

The disparity in breeding practices became even more pronounced when farmer-breeders using (post-2008) genomic assessments for total animal merit outperformed those depending on the 1970s breeding philosophy of 50% type and 50% milk yield. This shift in the industry landscape was a wake-up call, as it demonstrated the competitive advantage of genetic indexes in predicting future production performance. The mold had been broken, and this new approach gave farmer-breeders a clear edge in production efficiency and total genetic quality.

Have you seen a change in your breeding practices?

Focusing on genetic indexes rather than pedigrees from well-known prefixes has dramatically changed the breeding business. Many of today’s top-performing herds were among the first to use genomic testing. In today’s competitive dairy breeding market, it is apparent that post-1980 innovations considerably changed dairy animal breeding techniques.

The Era of Genomic Giants: The Modern Landscape of Dairy Cattle Breeding 

Fast-forward to the present time. DNA indexes have become the starting point in animal selection decisions for breeders regardless of their trait priority: type, production, fertility, health, or functionality. For many traits, the age of genomic giants has firmly established itself. Seventy percent of dairy breed pregnancies are the result of using high total merit index genomic indexed bulls. This change demonstrates the decreased value farmer-breeders place on established superior daughter-proven sires 30-40 years ago. Acceptance and wide use of DNA information have replaced the questioning and skepticism of 2008 regarding genomic indexing. Breeding decisions today balance traits of most importance, as well as the accuracy of indexes and plans for future farm viability and sustainability.

The commercial paradigm for flourishing breeding herds has shifted dramatically. The days of high-income returns based only on a renowned prefix in a pedigree are over. Also, there is a selection for just one or two traits and long generation intervals. It is now all about high DNA-determined genetic merit for both males and females. Herd breeding strategies aim to produce high-indexing heifers. Dairy-sexed semen is increasingly utilized to control the size of the heifer herd, and there is a new revenue source from crossbred, half-beef calves. Lower-indexing cows and heifers are often implanted with elite embryos, guaranteeing maximum genetic improvement. The business of dairy cattle breeding is increasingly dynamic and financially based.

Lessons from Sheffield Farms: When Show Wins Don’t Translate to Genetic Legacy 

In May 1960, my family bought my grandfather’s dairy farm, a watershed point in our lives. At the same time, Sheffield Farms from St George Ontario, a well-known display herd, held their dispersal auction. Despite my developing interest in Holstein breeding, I did not attend the sale 50 miles away due to our pressing need to complete a new milk house. Sheffield Farms, known for its multiple show victories, sold cows for an average of CA$3,152 (equivalent to CA$33,506 in 2024) and one for an astonishing $22,000. At the time, the typical milk cow sold for just $325.

Twenty years later, curiosity prompted me to investigate the progeny of Sheffield Farms’ show-winning herd. To my astonishment, none of the top sellers at that auction had significantly affected the Canadian Holstein breed. The sole exception was a heifer calf sold for $4,500, which produced several show-winning daughters before fading into oblivion.

This analysis was eye-opening. It proved that the perceived value of a well-known display herd only sometimes converts into long-term genetic influence. What was genuinely important was not the herd’s show success but the herdsman’s skill to offer animals for competition. This insight highlighted a fundamental point – genetic examinations are significantly more critical than showring awards when planning for long-term genetic advancement.

The Sheffield Farms’ Sale significantly impacted my views. As the dairy cattle industry entered the age of comprehensive genetic studies, it became evident that young bulls with high-performance indexes had a much more significant influence on the breed than older, established bulls bred for show success.

Have prominent registered Holstein herds made a meaningful contribution to genetic improvement? This issue is worth considering, particularly recent advances in dairy cow breeding. Historically, renowned herds enjoyed status, were shown in glossy ads, won contests, and sold for high prices. However, their contribution to genetic improvement becomes less evident as we look deeper. Genetic evaluations (G.E.) and genomic testing have transformed the sector in recent decades. Young bulls with high-performance trait indexes have significantly influenced genetic progress and will result in enhanced milk output, improved efficiencies, increased overall herd health, improved female reproduction, and improved functionality of animals. While traditionally bred registered herds still exist, their leadership role has been replaced by high-merit genomic bulls, now the trend leaders.

Comparative Analysis: Canada, USA, and the World 

In Canada today, the method of breeding dairy cows has heavily embraced genomic studies, with most breed advancements based on DNA indexes. Canadian breeders have swiftly embraced high LPI genomic bulls, resulting in a contemporary marketplace dominated by performance-based selection measures. This forward-thinking mindset guarantees that the genetic merit in Canadian herds continues to flourish, with a growing split from once famous show-type herds.

Across the border in the United States, the scenario is quite similar, with minor regional variances. American dairy producers depend heavily on genetics, with many solely favoring productivity attributes. The presence of proven cow families and high-performance genomic sires in marketing reflects a delicate balance of history and modernity. Nonetheless, using modern genetic data is critical for making considerable genetic advancements. Individual breeders have a significant impact, especially those who can capitalize on high-index progeny and cutting-edge genetic research. Breeding herds often have groups of females with high genetic merit for milk solids yield, ideal breed type, or animal functionality to serve the industry’s evolving goals.

Looking at the worldwide scene, the trend toward genetic-based selection is consistent, while the amount of acceptance differs. Countries like Denmark and the Netherlands have pioneered genomics, quickly incorporating it into breeding efforts. This shift has yielded herds with excellent genetic value and impressive performance measures. In contrast, despite increased interest in genomics due to its promising results, conventional breeding procedures continue to be used in some regions worldwide.

So, how does this impact your personal breeding decisions? The evident message is the importance of genomic assessments and the high total genetic merit genomic bulls are rapidly advancing genetic improvement. If your breeding program continues to emphasize single or two-trait-focused selection, you should reconsider your approach. Consider how incorporating genomic information can improve your herd’s output, health, and overall performance. By matching your strategy with global trends, you can keep your herd competitive and profitable in a constantly changing dairy cattle breeding business. Setting your breeding goals is paramount to your dairy enterprise’s future.

The Bottom Line

The evolution of dairy cow breeding has moved to the tools of herd performance recording, data analysis, benchmarking, genetic research, identification of top females, and extensive use of elite genomic sires from the prior dominance of renowned registered herds. Historical patterns reveal that, although show-winning herds historically dominated, their genetic contributions fell short of their aesthetic attractiveness.

Genetic progress has always depended on progressive breeders capturing increasing data and providing it for industry analysis and use.

With the introduction of genomic assessments and the rising precision of genomic data, dairy producers today have unrivaled tools for driving genetic innovation and improving profit. As DNA indexing grows, breeders will make improved breeding decisions, resulting in calves with higher genetic values. However, this is about more than just cutting-edge technology. It is about incorporating these improvements into practical breeding tactics.

So, where are we going from here? Every dairy farmer and breeder must carefully evaluate their breeding practices. Are you using the most recent genetic data? Do you prioritize traits that will sustain your herd in the long term? The answers to these issues will influence individual enterprises’ success and the future of dairy farming.

As the industry continues to evolve, one thing is sure – a combination of careful research and practical breeding will drive the next age of dairy cow greatness. Preserving profit-focused traditions and embracing developments that provide actual, long-term advantages is essential. Dairy cow breeding’s future depends on all dairy industry stakeholders’ capacity to adapt, develop, and strive for genetic perfection.

Key Takeaways:

  • Pre-WWII, elite herds dominated with investor-backed ventures that set the standard for breeding quality.
  • In the mid-20th century, aesthetics often precede genetic productivity in herd priorities.
  • The advancement of genetic evaluations (GEs) marked a turning point, particularly from the mid-1960s to 1980.
  • Post-1980, the focus shifted decisively towards production enhancement using sophisticated GE methodologies.
  • Today’s breeding practices are dominated by genomic giants, with 70% of pregnancies resulting from high TMI genomic bulls.
  • “Famous” herds now rely less on legacy and more on proven performance metrics and DNA indexes.
  • The story of Sheffield Farms illustrates how historical show successes may not ensure lasting genetic impact.
  • The comparative landscape of dairy cattle breeding reflects differing influences between geography and breeder philosophy.

Summary:

This article tracks the transformation of Dairy cattle breeding from the pre-WWII era to contemporary practices, highlighting the changing influence of famous registered herds. Initially, elite herds were valued for breeding stock provision, yet post-WWII, they prioritized aesthetic traits at the expense of production improvements. As genetic insights solidified by the 1980s, the prominence of show herds waned, paving the way for genomic evaluations that reshaped modern breeding strategies. Presently, high-index genomic bulls surpass the historical impact of these herds. The article critiques the actual genetic influence of these renowned herds, drawing comparisons between practices in Canada, the USA, and globally. Examples like Sheffield Farms demonstrate that achieving show success does not necessarily correlate with long-term genetic legacy, critically examining past and present breeding paradigms.

The Seven Deadly Sins of the Dairy Breeding Industry

· Comments (0)
Friday, July 18th, 2014

No matter what industry you look at there are always going to be those people who are immoral, shiftless, self-gratifying and good-for-nothing.  Throughout the Middle Ages, the Catholic Church hierarchy emphasized teaching all lay people the Deadly Sins.  We here at the Bullvine decided to take a look at the Seven Deadly Sins in the context of the dairy breeding industry.  The following is what we found:

Lust

Who hasn’t lusted for money, food, fame, power or sex? Come on. We are not monks.  So we are all guilty of this at some point or another.  In the dairy breeding industry there are those who lust for money, fame and power.  Lust for these three desires has led many dairy breeders to their downfall.  Instead of just making their breeding and farm decisions based on sound judgment, they let the desire for money, fame or power influence them and, in the end, make investments or decisions that make no rational sense.  Funny that the animal associated with lust is the dairy cow.

Gluttony

Gluttony is an inordinate desire to consume more than that which one requires. This is often interpreted as selfishness. Essentially it is placing concern with one’s own interests above the well-being or interests of others.  This is one area that I can say very confidently that most members of the dairy community are actually not as guilty of.  (Read more:  Why the Dairy Community is the Greatest in the World….).  However, there are those that have a tendency to overindulge in show ring results.  While I am as big a fan as anyone of the tanbark trail, I often have to remind myself that it is just a passion and remember where it fits relative to the rest of the dairy industry.

Greed

Greed is the desire for material wealth or gain, ignoring the realm of the spiritual. It is, like lust and gluttony, a sin of excess. However, greed (as seen by the church) is applied to a very excessive or rapacious desire and pursuit of material possessions.   “Greed is a sin directly against one’s neighbor, since one man cannot over-abound in external riches, without another man lacking them.”  Lately, I see the dairy breeding industry getting “greedy” with their genetics.  Empire building A.I. companies are not sharing their early release semen, and breeders are now not willing to sell embryos from their top females.  Greed has undoubtedly infected the dairy breeding industry.

Sloth

Sloth is the avoidance of physical or spiritual work.  It certainly would be really hard to accuse most dairy farmers of avoiding physical work. However, there are definitely some areas where sloth is starting to creep in.  No, I am not talking about the skyrocketing number of breeders who are switching to robotic milking systems. These breeders are changing the type of work they are doing as opposed to the amount of work they do.  What I am talking about here are the breeders who are looking to take the easy way out.  On the tanbark trail, it is the breeders who expect to win at the big shows, but don’t realize how much work it takes and fail to do the work 365 days a year that it takes to achieve success.  For the average dairy breeder, I notice sloth tendencies when they make their breeding decisions.  Instead of taking the time to carefully do effective research on the best mate for their cows (Programs like GPS) they look for a quick and easy answer for their breeding programs. (Read more: gPs– Genetic Profile Systems – Dairy Cattle Breeding Made Simple).  Another example of sloth in the dairy breeding industry, is livestock photography.  Many professional photographers have gotten lazy and have let their ethics slide to a point where it is now downright sinful.  (Read more: Dairy Marketing Code of Conduct)

Wrath

Wrath, also known as “rage,” may be described as inordinate and uncontrolled feelings of hatred and anger.  Feelings of anger can manifest in different ways including impatience, revenge, and self-destructive behavior. In the dairy breeding industry, I notice this vice in many breeders choice of which A.I. unit to purchase their semen from.   Instead of purchasing semen from the A.I. company that has the best sire for their animal, some breeders let their anger for a certain organization cloud their judgment and lead to diminished returns in their breeding program.  There are also those who have turned their wrath on us here at the Bullvine (Read more: The Bullvine: Wanted Dead or Alive and  Why I Don’t Care If You Like Me)

Envy

Envy is the desire for others’ traits, status, abilities, or situation. There are many (yes I say many) dairy breeders that are guilty of this.  From those whose envy is relatively mild, such as case of envy over ownership of a certain animal, or breeding success to those that turn almost green with envy over the success of their fellow breeders.

Pride

In almost every list, pride is considered the original and most serious of the seven deadly sins and the source of the others. It is identified as believing that one is fundamentally better than others, failing to acknowledge the accomplishments of others and excessive admiration of the personal self.  In the dairy breeding industry, I notice this in many old school breeders who fail to recognize new tools such as genomics.  They believe that their “breeding strategy” is far superior to that of others and let pride get in the way of achieving even greater success.

The Bullvine Bottom Line

Remember – no one is perfect. Sin, like death, is an unassailable fact of life. It is also one of the last great taboos for public debate. We here at the Bullvine feel that it is possible and necessary to talk about sin in ways that enrich our industry, as well as our personal lives.     These sins have been the downfall of some. However, others find success through overcoming them. It is important to recognize the vices you’re susceptible to and to manage them. Otherwise, these seven deadly sins will be the downfall of your dairy breeding program.

Forget Genomics – Epigenomics & Nutrigenomics are the Future

· Comments (1)
Tuesday, January 14th, 2014

Two months ago I had one of those conversations. A friend said to me “you know Murray I am moving on from just simple genomics”. That perked my ears up and I listened more intently. “Yep I am now thinking about epigenomics”, he said. Well that was enough to set me off investigating what is out there that is beyond what our industry is currently considering and using when it comes to genomic.  Relax a little, this may seem like rocket science today, but it is in tune with what our industry has always done in the past.  We look to find more accurate ways of indentifying the elite animals. Then we figure out how knowing that information gives us ways to make dairy breeders and dairy farming more profitable.

Already Many Steps Too Far?

So now ‘epigenomics’ was pinned to my clipboard. But I didn’t get any further before I had a Master Breeder husband and wife corner me for half an hour and ‘inform’ me that “The Bullvine was leading the industry astray”. They stated to me that “they were from Missouri” and perhaps we should “still only be using the actually officially authenticated information – DHIR records and breed classification results – when it comes to selecting bulls and marketing females.  They asked how can we know that the hair pulled and submitted for DNA testing actually came from said animal.” I have known this couple for almost forty years so I took the discussion on to a review great cows of the past and how they would not compare to the great show and brood cows of today. As we started to conclude our conversation the lady, who had been somewhat quiet during our sharing, commented “You (Murray) have a good point about how the genetic evaluation results over our lifetimes have resulted in the fact that we have far superior cows for both conformation and production, but our herd’s current biggest genetic problem is cows not getting back in calf. We just do not now get to have very many ten year old and older cows in our herd, liked we used to.” That gave me the opportunity to talk to them about genomics and having fairly reliable information, early in an animal’s life, on its genetic merit for reproductive traits.

The husband’s concluding comment warmed my heart. “Our grandson plans to come home to our family farm and he tells us that at university his professors are saying the information we have today on genomics is just the start. So don’t give up on us old guys. You folks at The Bullvine just keep giving us the facts and helping the industry do an even better job of breeding dairy cattle. We don’t own a computer but our family keep us quite up-to-date on what The Bullvine is writing about.”  Obviously this couple are not as set in their ways as they led me to understand at the start of the conversation.

So if we have just scratched the surface, let’s delve a little deeper.

Epigenomics – What’s That?

By definition, epigenomics is the study of modification of the expression of the genetic material in a cell. Sounds rather out of the norm. Something can alter what the DNA says is the genetic merit of an animal? Let’s think that through a bit more.

As cattle breeders we can all think of times when three full sisters all had very similar performance. And I expect many of us can also remember situations where two of the sisters were very similar but the third sister just did not measure up to the other two.  The question that breeders always ask is did the third one not get the good genes, or did she get the good genes but something inhibited her from being able to express them.  I have even heard very knowledgeable breeders say that the third one will breed just a good as the other two.  How they arrived at that conclusion I am not really certain. But I have seen it happen as they predicted.

Research in mice has shown that the diet of a sire can influence the gene expression of their progeny. So that fits under the definition of epigenomics. Dr. Jacques Chesnais of Semex feels that “there is a definite possibility that epigenomics plays as important role in adaption to the environment. In particular, in our industry, the way we feed and treat a cow in the early stage of pregnancy could affect the calf for a lifetime and therefore affect the future productivity of the herd.” Hearing that made me wonder if the recipient dams of ET calves may have an influence on how those calves pass on their genetics.

Leaders in the study of epigenomics in livestock Dr Marc-Andre Sirard and Dr Claude Robert, Laval University, are currently  investigating how epigenomics applies to the bovine and in particular to female reproduction and embryo development. It will be interesting to follow their reports.

There is obviously much to be studied and learned about epigenomics in the bovine. Definitely traits like reproduction, health and immunity are ones that dairy breeders wish to know more about as they relates to inheritance.

So then – What is Nutrigenomics?

The second new kid-on-the-block, so to speak, is nutrigenomics. The study of the effects of foods and food constituents on gene expression. By definition “Nutrigenomics can be described as the influence of genetic variation on nutrition, by correlating gene expression or SNPs with a nutrient’s absorption, metabolism, elimination or biological effects.” Think about it. If we know the genetic make-up of our dairy cows we would be able to design their diets accordingly. Are there cows out there that can make better use of lower quality forages? Wouldn’t that be a boon for the economics of dairy farming. Especially given that feed costs are 52-58% of total dairy enterprise costs and low quality forages are less costly.

I asked two nutritional consultants about this. I got two very different responses. The first one said – “don’t bring that on too quickly I still have another ten to fifteen years in my working career”. The other consultant said “Well it would change my job but if it means dairy farming can be profitable and sustainable and if we can feed the hungry world – well bring it on”.

Expect Genetics to Play an Even Bigger Role in the Future

Investigation by Canadian Dairy Network (CDN) has predicted that, in stable milk pricing times and on milk production focused farms, half of the increased on-farm profits comes from increasing the genetic merit of sires and cows used to produce the next generation of females.  With a better understanding and more definitive knowledge of epigenomics and nutrigenomics it could possibly be that 60+% of on-farm profits could be as a result of the genetics used.

From the DNA analysis using hair follicles, breeders now know with 50-70% accuracy the genetic merit of their animals for a host of important traits. Think what might be possible if by including epigenomics and nutrigenomics information. The accuracy levels could rise to 70-80%.

The Bullvine Bottom Line

The research phase of studying how epigenomics and nutrigenomics relate to the dairy cow is well underway. We can expect refinements to our genetic evaluation procedures based on what the research tells us.  And in time breeders will have information so they can better breed, feed and manage their herds. Stay tuned to the Bullvine for more great insight into these two future changing technologies.

CATTLE BREEDING: If we don’t change we don’t grow

The Art of Livestock Breeding: It starts with a need

The breeding of domesticated livestock has long been considered to be an art practiced by food producers of the world. It is has definitely not been static. It started with observant farmers seeing an opportunity to improve the attributes of their stock. Initially this meant fixing the characteristics of their stock and establishing breeds. Breed purity was the primary focus which often meant coat colour in cattle or ability to pull heavy loads in horses; reproduction rates in pigs’, egg production volume in chickens; ability to find their way home in carrier pigeons and so on as the need or goal was established.

Dairy Cattle Breeding: The cream rises to the top

Over the centuries species and breeds have evolved. In cattle it meant animals that were developed for draught, meat and milk production. Milk has achieved special designation and has been recognized as nature’s most perfect food. Over time, there have been hundreds of attempts at developing breeds of cattle for their milk producing ability. That progressed to the point where there were only a few. Today Holstein and Jersey are the major survivors. These breeds were developed in temperate regions of Europe each with their own characteristics.

Advancement of North American Breeding: No decade stands still

Over the twentieth century dairy farmers in North America have molded their dairy cattle into what they are today by taking many steps. A brief and not all inclusive synopsis of some of those changes by decade are:

Early 1900’s Milk recording groups formed to authenticate volumes and milk quality
1920’s Type Classification programs started
1930’s With electricity came the start of machine milking, larger herds and the need for teats to point to ground and be close together
1940’s Artificial insemination, the painting of breed True Type pictures and the need for milk not to carry diseases humans could contact
1950’s Mechanization of field work resulted in farms specialization, improved forage quality, off farm processing of milk and sire daughter raw averages
1960’s Sire proving coops were formed, milk recording started to be used for more than just animal authentication purposes and farmer marketing coops were established
1970’s Greatly expanded numbers of young sires being sampled, BLUP analysis technique and genetic indexes for both bulls and cows
1980’s Significant changes in genetic indexing methodologies, breeds and breeding companies with specified breeding strategies, the practise of on-farm preventive medicine programs by veterinary practices and amalgamation of farmer coops for recording, breeding and milk marketing
1990’s Dairy cattle breeding adopted more finely tuned breeding formula’s (TPI, LPI and Net Merit), total mixed rations, on-farm least cost feeding, increased on-farm management practises including computer software programs, data analysis to better predict genetic merit, and in Canada governments , due to budgetary constraints removed themselves from the provision of milk recording and genetic indexing services
2000’s Greatly enhanced rates of genetic advancement, capture of data for auxiliary and functional traits, refinements in breeding strategies to consider more than milk and conformation, routine use computerized farm management for both production and economics, greatly expanded herd sizes,management took on greater importance on all farms and researchers started to consider if the DNA make-up of an animal could be used for genetic advancement

Finding a New Path: Adding Genomics

Very definitely the move about five years ago by a few AI companies and the USDA to compare the DNA snips results with the genetic evaluations for dairy bulls proven in the USA and Canada was significant. However the decision not only to study but to make the results openly available to breeders was a gigantic step. Breeders could know the genomic results for bulls and cows. This meant that breeders were central to the genetic future of their animals and their industry. Compare that to the swine and poultry industries where relatively few breeding companies own the genetics of the world. Now in 2012 all dairy cattle breeding regions of the world are using, or are about to use, genomics to evaluate their animals’ genetic composition.

The Bullvine Bottom Line

I have always noticed that people who make a difference are the ones who, not only don’t resist change, but welcome it. It is important that producers through their breed societies and breeding coops continue to have open minds and collectively research and develop the genetics of their dairy cattle. If breeders are to govern their destinies, they need to make sure that their elected and organization officials are objective and dynamic in how they approach changes to cattle breeding such as genomics. Many changes are yet to be thought of. We always need to remember that, “When you are through changing, you are through.”

The Genomic Advancement Race – The Battle for Genetic Supremacy

· Comments (4)
Tuesday, February 28th, 2012

In the race to have the next great sire, there comes a point where you have to ask have we taken it too far.  Analysis performed by Holstein International of the 33 popular genomics bulls of 2009 showed that only one has managed to maintain his breeding value: O-Style.  Even with those facts, why are so many A.I. companies now basing 70%, 80%, and 100% of their genetic programs on genomic sires?

Partly due to the “shortage” of new daughter proven sires of sons, and partly due to the increased confidence in genomics since it started in 2009 the percentage of breeding programs that are using genomic sires has increased from 40% to 50% on a global basis.  Moreover, just like a great outlier sire, the difference between the AI’s is substantial.  With Accelerated Genetics, Genex-CRI and Alta Genetics all sampling over 90% genomics sires.

So why are these studs putting so much weight in genomics?  Do they know something the rest of us don’t?  Have they just gone cuckoo?

In reality is actual goes back to the genetic advancement formula that has been around for many years.

Let’s take a close look at each piece of this equation and the effect genomics has.

Accuracy

The effect that genomics has on accuracy is very significant.  According to CDN the average gain in accuracy in LPI due to Genomics is as follows:

Selection Intensity

In the past AI companies would have sample multiple sires from the same cross, and try multiple crosses to find out which one was the genetically gifted.  That does not even take into account the need to sample from a larger portion of the top females to discover which ones where genetically gifted and which ones where “artificial” in their breeding values.  With genomics, they can pre-screen these sires and crosses to see which ones will have the highest chance of producing the next top-selling sire and which ones did not get the best their parents had to offer.

By eliminating the need to sample such a large number of sires, allows the AI companies to focus on a more intense core group of sires, and push the limits on genetics advancement

Genetic Variability

This is one area than many breeders do not pay enough attention to.  Certain traits, such as Milk Yield, Protein Yield, and stature are much more heritable than others (i.e. Rump and Feet & Legs).  What this means is, if you spent all your time breeding for feet and legs, you will see less overall genetic gain than say focusing on production traits.  That is why production sires will typically offer the greatest genetic gain, since most type traits have a much lower heritability.  It’s also why breeders always need to be conscious of production when building your breeding program and don’t mate for low heritability traits.

The following is Holstein heritability estimates used for genetic evaluations in Canada

  • Production Traits
    • Milk Yield 43%
    • Fat Yield  34%
    • Protein Yield 40%
    • Fat Percentage 50%
    • Protein Percentage  50%
  • Functional Traits
    • Somatic Cell Score  27%
    • Lactation Persistency 40%
    • Herd Life  10%
    • Calving Ability 6%
    • Daughter Calving Ability 6%
    • Milking Speed  21%
    • Milking Temperament 13%
    • Daughter Fertility 7%
  • Major Type Traits
    • Conformation 26%
    • Rump 15%
    • Mammary System 25%
    • Dairy Strength 36%

Time

In order to cut down the genetic intervals many AI companies are now using genomic sires themselves as sires of sons.  This means that there are sires of sons that don’t have any daughter information yet.  The company taking this to the extreme is Alta Genetics.  Their breeding program is made up by no less than 70% of genomic bulls that are sired by genomic bulls.  The greater you can cut down the interval from the birth of the parent to the birth of the progeny the greater the average genetic gain per year.Yes, you will run the risk of sires that drop, but overall on a large breeding program you will come out ahead.

The Bullvine Bottom Line

Many AI companies, especially in North America, are pushing the edge with genomics to maximize annual genetic gain.  While they will run the risk of a sire not turning out, or dropping significantly from his pre-proven prediction, when you look at the net result over the generations of their whole breeding program they will come out way ahead.  By leveraging the effect Genomics has on accuracy, selection intensity, focusing on highly heritable traits, and making the interval between generations as low as possible, these studs stand the greatest chance of consistently producing the best genetics available.
