How Calf Birth Weight Influences Dairy Cow Performance: Insights from a Large-Scale Study

Discover how calf birth weight impacts dairy cow performance. Can lighter calves boost milk yield and efficiency? Dive into insights from a large-scale study.

Consider the birth of a calf, a routine event on a dairy farm. Yet, the weight of a newborn calf can significantly impact its mother’s future performance. Recent research sheds light on the relationship between calf birth weight and dairy cow productivity, providing farmers with valuable insights. 

This association is crucial for dairy farmers aiming to optimize their herd’s performance. Key findings from a study analyzing over 11,000 lactation records include: 

  • For primiparous cows (first-time mothers), lower calf birth weight was linked to higher milk yield in the first 60 days and shorter intervals to the first service.
  • In multiparous cows (experienced mothers), higher calf birth weight correlated with increased total milk, fat, and protein yield.
  • The sire breed also influenced 60-day milk yield in multiparous cows when calf birth weight wasn’t considered.

These findings have direct implications for dairy farmers, underscoring the importance of calf birth weight as a predictor of dairy dam performance. By incorporating these insights into their practices, farmers can potentially enhance their herd’s productivity and overall efficiency.

Factors Influencing Calf Birth Weight

Understanding the role of genetic factors in calf birth weight is crucial for dairy farm management . The genetic makeup of the sire and dam significantly influences calf birth weight, making strategic breeding choices and maintaining genetic diversity within the herd key factors in optimizing calf birth weight. 

Maternal nutrition during pregnancy profoundly impacts calf birth weight. Balanced nutrition is vital for the pregnant dam’s health and fetal growth. Nutritional deficiencies or excesses can lead to variations in birth weight, affecting subsequent calf performance

Environmental factors, such as stress and climate, also induce variability in birth weights. Extreme temperatures, poor housing conditions, and other stressors can affect the dam’s pregnancy and, thus, the calf’s birth weight. Mitigating these stressors can promote consistent and favorable birth weights, enhancing overall well-being

These insights highlight the need for a holistic dairy herd management approach, harmonizing genetic selection, nutritional planning, and environmental control to optimize outcomes for both calves and dams.

Impacts of Calf Birth Weight on Dairy Cow Performance

The association between calf birth weight and dairy dam performance extends beyond immediate post-calving metrics, impacting long-term productivity and health. Higher birth weight calves generally exhibit better growth rates, which enhance overall herd health and operational efficiency. This growth is often coupled with improved immune function, reducing early-life diseases and calf mortality, leading to a healthier adult herd and lower veterinary costs. 

Calf birth weight significantly influences future milk production and reproductive performance. Heavier birth-weight calves tend to transition to adulthood with fewer health issues, reaching peak milk production more efficiently. For dairy dams, calving heavier calves can improve milk yield and reproductive metrics. In primiparous cows, this includes shorter intervals to first service and higher body condition scores. In multiparous cows, there’s a notable association with total milk, fat, and protein yield and a reduced drop in body condition score from calving to nadir. 

By managing calf birth weight, dairy farmers cannot only optimize immediate lactation outcomes but also enhance the long-term efficiency of their farms. This underscores the importance of strategic breeding and nutrition in achieving optimal birth weights, which can lead to a more productive and sustainable dairy farming environment.

Recommendations for Dairy Farmers

Given the intricate ties between calf birth weight and the dairy dam’s post-calving performance, dairy farmers play a crucial role in proactively managing their herds. Here are detailed recommendations: 

  • Monitor and Record Calf Birth Weights: Keeping meticulous records of calf birth weights allows for identifying patterns and anomalies within the herd. This data can be invaluable for making informed management decisions and refining breeding strategies that align with the farm’s productivity goals.
  • Improve Maternal Nutrition and Reduce Stress: Ensuring cows receive optimal nutrition and experience minimal stress during pregnancy can positively affect calf birth weight. Farmers should focus on balanced diets that cater to the specific needs of pregnant cows and adopt management practices that reduce stress factors such as overcrowded housing or abrupt environmental changes.
  • Genetic Selection for Optimal Birth Weights: Implementing breeding programs prioritizing genetic traits associated with favorable birth weights can enhance calf and dam health. Selecting sires with a proven track record of producing calves with optimal birth weights can improve overall herd performance in milk yield, fertility, and body condition scores.

By integrating these recommendations, dairy farmers can foster a more robust and productive herd, ultimately enhancing farm sustainability and efficiency. This not only promises improved milk yield and cow health but also sets the stage for a more prosperous and sustainable dairy farming environment.

The Bottom Line

The study reveals a subtle yet notable link between calf birth weight and the performance of dairy dams. These findings, while the effects are generally small, provide valuable insights for dairy farmers. Primiparous cows showed associations with calf birth weight across performance metrics like milk yield and body condition scores. The calf’s weight influenced total milk, fat, and protein yields for multiparous cows. Interestingly, multiparous cows with traditional beef breed calves produced more milk than those with Holstein-Friesian calves. 

These results emphasize the importance of more research. Understanding how calf birth weight impacts dairy cow performance could drive new strategies for optimizing dairy farming efficiency, which is pivotal for productivity and animal welfare

Dairy farmers should consider calf birth weight in herd management. This focus can lead to better decisions on milk yield, cow health, and overall performance, promoting a productive and sustainable dairy farming environment.

Key Takeaways:

  • Calf birth weight is linked to critical dairy performance metrics, influencing both immediate and long-term productivity.
  • Primiparous cows (first-time mothers) show a direct correlation between lower calf birth weight and higher milk yield within the first 60 days of lactation.
  • Multiparous cows (experienced mothers) with lower birth-weight calves demonstrate decreased milk, fat, and protein yields over the first 305 days of lactation.
  • The sire breed of the calf plays a crucial role, with traditional beef breeds leading to higher milk production than those sired by Holstein-Friesians in multiparous cows.
  • The biological impact of these associations, though statistically significant, is relatively small, underscoring the complexity of dairy cow performance factors.

Summary: Research indicates a significant correlation between calf birth weight and dairy cow productivity, particularly in primiparous cows. Primiparous cows have lower calf birth weight, while multiparous cows have higher total milk, fat, and protein yield. The sire breed also influences milk yield in multiparous cows. Factors influencing calf birth weight include genetic factors, maternal nutrition during pregnancy, environmental factors, and environmental control. The genetic makeup of the sire and dam significantly influences calf birth weight, making strategic breeding choices and maintaining genetic diversity crucial. Maternal nutrition during pregnancy is vital for fetal growth, while environmental factors like stress and climate can induce variability in birth weights. The association extends beyond immediate post-calving metrics, impacting long-term productivity and health. Higher birth-weight calves generally show better growth rates and operational efficiency.

Strategies for Dairy Farmers: Managing Feed Variation to Minimize Economic Stress

Find out how to handle feed variation and reduce stress on your dairy farm. See how you can cut losses and increase profits with better feed management.

Are you a dairy farmer trying to increase profitability without sacrificing your cows’ health or stress-free condition? Your daily operations depend on feed management, which frequently makes up 45% of your expenses. A well-controlled feed saves money and reduces stress for your staff and herd. Adjusting feed methods may mitigate financial losses and improve cattle health.

Read more for advice on reducing feed variability and stress. From bunkers to total mixed rations (TMR), these pointers will assist in simplifying processes and improving output. All set for some practical, financially wise guidance? Let’s go right in.

Overcoming Feed Variations: Ensuring Herd Health and Economic Stability 

Your herd’s health and the financial stability of your dairy farm may be much influenced by control of feed changes. At the bunker silo, silage packing and sealing are very vital. Here, poor methods cause oxygen intrusion and feed spoiling, compromising nutrients and generating financial waste.

Inconsistent mixing periods and imbalanced ingredient loading at the feed mixer might produce a TMR lacking consistency. This encourages cows to sort the feed, therefore upsetting their balanced diet and raising their chance of stomach problems.

Uneven particle sizes in feed may impede digestion in the cow’s stomach. Too tiny particles increase the danger of acidosis, while coarse particles lower the microbial digesting efficiency. Both badly affect herd health and milk output.

Economically, feed spoilage and digestive problems may cause wasted feed investments, decreased milk output, more veterinary bills, and less profitability. Strict feed management techniques assist in guaranteeing that your feed investment optimizes herd health and production.

Mastering Bunker Management: The Cornerstone of Dairy Farm Success 

The success of a dairy farm depends on good bunker management, which affects feed quality and the economy. Concentrate silage face management, feed-out rates, sealing quality, and packing density to save feed and lower spoilage.

When cutting silage, silage face management involves maintaining a smooth, vertical face. This reduces rotting and air exposure. Sharp cutting tools can also protect the silage integrity and prevent jagged edges.

Remove around thirty centimeters of silage daily for feed-out rates to minimize aerobic deterioration. Timing and amount are critical to maintaining a fresh, constant-quality feed for your herd.

Sealing Quality is really crucial. Seal the bunker silo with premium plastic and oxygen-limiting barrier films; fasten them with tires or sandbags. This maintains an anaerobic condition, therefore conserving feed nutrients and avoiding spoiling.

Over 700 kg of dry stuff per cubic meter is a necessary packing density. Layer and crush silage completely with heavy equipment to remove oxygen pockets and preserve silage quality.

Using these techniques improves dairy profitability and helps reduce feed waste. Proper bunker management is critical to the financial viability of your farm.

Optimizing Silo Dimensions: A Key to Safe and Efficient Feed Management

Silo dimensions are crucial for safety, cost, and feed management. Ensure the maximum height is accessible by defacing equipment and the minimum width matches two packing trailers. 

Remove 30 centimeters of silage daily to limit oxygen infiltration and minimize spoilage. Pack and seal the pile carefully, using plastic and oxygen-limiting barrier films secured with tires or sandbags.

Adhering to these guidelines maintains a reasonable feedout rate, enhances safety, and boosts dairy farm profitability.

Effective Silo Packing and Covering: Your Key to Reducing Spoilage and Boosting Silage Quality 

Packing and covering your silo correctly is critical to keeping oxygen out and preserving silage quality. Spread the silage evenly during filling to ensure uniform density. Use heavy machinery for tight packing to minimize air pockets. 

Cover the silo immediately with high-quality plastic and oxygen-limiting films to create an airtight seal. Lay the plastic carefully, avoiding gaps or tears. 

Secure the cover with tires or sandbags placed closely side by side. This helps maintain the seal and adds pressure. Focusing on these steps can reduce dry matter loss and preserve nutritional value, boosting profitability.

The Art of Feedout: Safeguarding Your Silage and Your Bottom Line

Removing silage from the bunker is a vital part of feedout practices. Proper removal prevents spoilage and ensures quality feed for your cows. Aim to remove about 30 centimeters of silage daily to keep it fresh and maintain the silage face. Please ensure no leftovers are at the bottom, as they can spoil and lead to economic losses.

Total Mixed Ration (TMR): The Backbone of Effective Feed Management 

The Total Mixed Ration (TMR) is vital for effective feed management in dairy farming. It ensures each cow gets a balanced diet, providing a mix of forages, grains, proteins, vitamins, and minerals crucial for cow health and milk production. 

Fiber and forage in TMR are essential for chewing and saliva production, which help maintain ruminal pH and a healthy rumen. Proper pH levels prevent digestive issues like acidosis, which can harm cow health and milk yield. 

However, TMR benefits can be recovered if forage particles are shorter. Otherwise, cows will sort the feed and miss essential nutrients. Conversely, particles that are too short may not provide enough fiber. 

Accurate measurement and mixing of feed ingredients are crucial. Tools like Feed Supervisor can track TMR composition and allow real-time adjustments. By doing so, dairy farms can enhance herd nutrition and farm profitability.

Optimizing Forage Particle Size: A Catalyst for Higher DMI and Enhanced Milk Production

The physical characteristics of the ration are crucial for increasing dry matter intake (DMI) and meeting your cow’s energetic needs for milk production. When forage particles are sized correctly, cows can consume more feed efficiently. However, if particles are too long, they can cause rumen distention and potential health issues. 

Proper particle length helps maintain rumen health by preventing selective eating, where cows leave behind coarser feed. This can lead to an unbalanced diet and digestive disorders like acidosis. Addressing this ensures balanced intake, promotes cow health, and optimizes milk production.

The Meticulous Preparation of Total Mixed Ration (TMR): How to Optimize Productivity and Profitability 

The meticulous preparation of Total Mixed Ration (TMR) directly impacts your farm’s productivity and profitability. Here’s how to ace it: 

  • Ingredient Order: Load long forages first, then smaller forages, grains, and supplements. This ensures even mixing.
  • Scale Accuracy: Calibrate your scales regularly. Accurate weighing guarantees a balanced diet for every cow.
  • Mixing: Use moderate speed and recommended times. This ensures a uniform mix.
  • Ration Distribution: Distribute TMR evenly in the feed bunk to avoid nutrient imbalances.
  • Feeding Frequency: Feed and push up frequently to keep TMR fresh, boosting intake and preventing selective eating.

Following these TMR prep steps enhances feed investment returns. Balanced nutrition boosts rumen health, dry matter intake, and milk production, leading to higher profits.

The Bottom Line

Effective feed management is critical to your dairy farm’s success. By addressing feed variations—from silage prep and silo dimensions to TMR consistency—you can reduce waste and boost milk production. Proper bunker management and meticulous silo packing maintain silage quality while optimizing forage particle size in the TMR ensures a balanced diet and reduces digestive issues. 

Comprehensive feed management improves herd health and dry matter intake (DMI), driving milk production efficiency. Reporting tools help make informed decisions, reducing feed costs and boosting profitability. Consistent feeding practices enhance livestock health and productivity, proving that well-managed feed solutions are crucial for your dairy farm’s economic stability.

Key Takeaways:

  • Effective feed management is critical to reducing economic losses in dairy farming.
  • Proper bunker management techniques can minimize feed spoilage and maximize profits.
  • Well-optimized silo dimensions are essential for safety and efficient feed management.
  • Packing and covering silage properly can significantly reduce the risk of oxygen infiltration and spoilage.
  • The total mixed ration (TMR) must be balanced to avoid digestive disorders and improve cow health.
  • Ensuring the correct forage particle size can enhance dry matter intake (DMI) and milk production.
  • Precise TMR preparation, including correct ingredient loading and mixing instructions, can boost farm productivity and profitability.

Summary: Dairy farmers must prioritize feed management to increase profitability without compromising cow health. Feed management accounts for 45% of daily expenses and can save money, reduce stress, and improve cattle health. Poor bunker management methods can lead to oxygen intrusion, feed spoiling, nutrient compromise, and financial waste. Inconsistent mixing periods and imbalanced ingredient loading can cause a TMR lacking consistency, leading to cows sorting the feed and increasing the risk of stomach problems. Uneven particle sizes in feed can also hinder digestion, affecting herd health and milk output. Mastering bunker management is crucial for dairy farm success, as it affects feed quality and the economy.

Optimizing silo dimensions is essential for safety, cost, and feed management. Feedout practices are essential for dairy farming, ensuring quality feed and preventing spoilage. Accurate measurement and mixing of feed ingredients are crucial, and optimizing forage particle size is essential for higher dry matter intake and enhanced milk production. Preparing TMR directly impacts farm productivity and profitability, boosting rumen health, dry matter intake, and milk production, leading to higher profits.

Manure Evaluation: Key to nutrition and herd health

Awareness is one of the best tools dairy managers can make use of.  A daily barn or pasture walk with boots that don`t hesitate to poke into manure piles behind the cattle, can be a valuable signal of what`s happening with herd health and nutrition.  No special equipment is required to make a speedy determination of the color, consistency and content of the manure being passed by a group of dairy cows.

The Three C’s: Consistency, Color and Content

If the cows share the same diet, their manure should share similar characteristics.  In a 200-cow dairy, a walk-through that checks the manure of 15 to 20 cows should be able to provide enough observations to draw conclusions. The expectation is that less than five per cent will stand out as significantly different from the general herd.  It is important to determine what is causing the difference.

Check Consistency First!

Feed drives production.  Knowing the digestion status of the working cows is an important tool for making management decisions. What you see in the manure output, should be porridge-like and produce the dome-shaped  1 or 2 inch thick ‘plop’ that is the sign of healthy digestion.   Feed type, the nutrient and fibre content, water quality and intake and passage rate all have an impact on the final product.  Restricted water or protein produces firmer feces.  Dehydration results in firm balls of manure. Seeing loose feces or diarrhea may indicate excessive protein intake or high levels of rumen degradable protein.  Manure may be loose during periods of stress.  Other cases of loose manure are far more serious and their actual causes seem to be harder to pinpoint. For example, sub-clinical acidosis (SARA) causes loose manure consistency to vary amongst herd members as well as other multiple changes over time for each suffering cow.

Color Paints a Management Checkpoint

Fecal color is influenced by feed type, bile concentration, and the passage rate of feedstuffs and digesta. Recognizing what is `normal` for the current type of diet being fed, sets up the opportunity to identify variations that could indicate a need for action. Typically, manure is dark green when cattle graze fresh forage and darkens to a brown-olive if animals receive a hay ration.  When cows consume a typical TMR, feces are usually a yellow-olive color. This color results from the combination of grain and forage and will vary by the amount of grain and processing of that grain. If an animal experiences diarrhea, feces may change to a gray color. Animals undergoing medical treatment may excrete abnormal colored feces as a result of drugs that are administered.  Dark or bloody manure may indicate hemorrhaging in the gastrointestinal tract from watery dysentery, mycotoxins, or coccidiosis.  Light-green or yellowish manure combined with watery diarrhea can result from bacterial infections such as salmonella. Of course, any rapid change in colors signals that something is not right and immediate corrective action needs to be taken.

Content is Last but Not Least!

The third “c” to inspect is content. The contents of manure can provide dairy managers with information about how the dairy diet is working. Manure that is produced from cows fed a well-balanced nutritious ration (with adequate effective fibre) is very uniform. It contains digested feed particles with the majority of processed forage fibre no greater than 1/2 inch, and with little escaped grain.

Long forage particles or undigested grains are a sign that rumination has been challenged and the cause needs to be determined.  It could be a problem with the animal or with the processing of the grain itself.  Obviously these large particles in the manure mean that the nutrition in them has not been made available to the animals or to rumen microbes.

Mucus is another indicator to use as an alert.  The presence of excessive amounts of mucus indicates chronic inflammation of or injury to gut tissue. Mucin casts also may be observed. These indicate damage to the large intestine, possibly caused by extensive hindgut fermentation and low pH. The mucin is produced by cells lining the intestine in an attempt to heal the affected area. As well manure that appears foamy or bubbly may indicate lactic acidosis or excessive hindgut fermentation resulting in gas production.

A Poop Picture Helps with Informed Decision Making

manure scoring

Manure scores 1 and 5 are not desirable and may reflect a health problem besides dietary limitations. Score 4 droppings may reflect a need to rebalance the ration. As cows progress through their lactation, manure score may also shift as outlined below.

  • Fresh cows (score 2 to 2 ½)
  • Early lactation cows (2 ½ to 3)
  • Late lactation cows (3 to 3 ½)
  • Far off dry cows (3 to 4)
  • Close up dry cows (2 ½ to 3 ½)

Increasing the amount of degradable, soluble, or total protein; deceasing the amount or physical form of the fiber; increasing starch level, decreasing grain particle size (such as fine grinding or steam flaking), and consuming excess minerals (especially potassium and sodium) can cause manure scores to decline (for example from 3 to 2).

The color of manure is influenced by feed, amount of bile, and passage rate. Cows on pasture are dark green while hay based rations are more brown. High grain-based diets are more gray-like. Slower rates of passage causes the color to darken and become more ball-shaped with a shine on the surface due to mucus coating. Score 1 may be more pale due to more water and less bile content. Hemorrhage in the small intestine causes black and tar-like manure while bleeding in the rectum results in red to brown discoloration or streaks of red.

Physical Analysis

When it comes right down to manure evaluation, you have to get right down to it.  After the 3 C’s inspection using eyes, boots and cow sense information, it’s time to look deeper. Collect at least five manure samples that appear to be representative of the group of animals. Mix the collected samples and place a pint-sized sample on a .05-.08- inch mesh sieve or in a strainer. Using a hose, wash a gentle, steady stream of water over the sieve, passing across the sample continuously until the water running from the bottom of the sieve is clear. Then gently use running water to roll or float the particles to one corner of the sieve and remove all material from the sieve.

Place the washed sample on a flat dark surface and examine it for the following:

  • Long fiber particles — It is inevitable that some long forage particles will appear, but if most are greater than 0.5 inch there may be cause for concern. Poor digestion of forages may be due to the makeup of the fiber component of the diet (low quality forages) or to the ability of the animal to digest the forage being fed (poorly balanced rations).
  • Grain particles — The small intestine is capable of digesting starch, allowing the cow to utilize this nutrient. However, the amount of starch digested is limited by the rate of digesta passage through the small intestine.

The Bullvine Bottom Line

It cannot be overemphasized how important it is to effectively manage herd health and nutrition.  Every tool that informs that decision making process is valuable and manure evaluation is a valuable link in that chain of understanding.  Don`t overlook the simplicity of a boots through the barn examination of your herd’s manure production.  It’s not science but it gives the start to analyzing how your dairy diet is being consumed, digested and left behind.

How Healthy Are Your Cows?

There are  some herds where the temperature is checked on fresh cows twice a day for the first couple of days after calving. But for the rest, how many of us know the temperatures and the borderline sicknesses of animals in our herds?  Should we?

Let’s look at this a little closer.

Lost Dollars

“The economics of animal disease are huge and often unrecognized.”

“A goal of every dairy producer is to have healthy cows that breed back quickly.”

“Early detection of disease reduces the cost of disease to the farm and increases the length of animals’ lives.” These are three quotes from Dr Jeffrey Bewley, a University of Kentucky Professor whose research focus is precision economics.

Consider your own farm. If you are not 100% aware of the health status of every animal on your farm, how can you know the dollars disease is costing you?

There are  numbers reported that say  each mastitis case costs us $350-$400 or that each extra day open for our milking herd costs us $4 – $5 in lost profit.  But do we know anything about our heifer herds?  What does a case of calf pneumonia or scours cost? How much of our labor costs are associated with treating sick animals? And then there are costs to subclinical disease that we do not even know exist (Read more: Dollars and Sense: Herd Health and Reproduction).

The Big Unknown

How many disease incidents get missed on our farms?  Let’s admit it, we do not know.  If we could have an army of herd persons, we might come close to knowing but then our bank balance would be a very large negative number.

So let’s step away from dairy farming for a minute.  Let’s go to our local hospital, where sick people are nursed back to health. The patient is hooked up to machines for constant monitoring so that the Doctors and Nurses can use the numbers to make decisions.  Continuous monitoring.

Wouldn’t it be great to make informed decisions by having numbers provided by continuous animal health monitors on dairy farms??

Enter Precision Dairy Farming

The Bullvine has discussed milking robots (Read more: Robotic Milking: More than just automation it’s a new style of herd management and FRANCISCO RODRIGUEZ: Passion with a Purpose) but they are just one of many devices that capture continuous observations on our dairy farms.  Besides milk yields robots have information on milking speed, milk temperature and electrical conductivity by each quarter.  Someday soon they may be able to capture fat % and protein%.

Is it any wonder that robot owners tell us that they have never known as much about their cows and managed them so well?

But robots exist beyond the milking herd.  Calves can now be fed robotically.  And other devices are arriving on the market every year to capture more animal performance information.

Another way to consider precision dairy farming is to think in terms of more data to manage with and  make more profit from.

Like to “Know”

However before going further into what equipment is out there to capture on-farm animal data. it is important to know where you’re starting from. What are the biggest health challenges on your farm?

How would you rank the following?

  • heat detection / timing of breeding / cows not showing heats until over seventy days in milk
  • heifers not detected in heat until after fifteen months of age / heifers not calving until 27 months
  • LDAs / milk fever / ketosis
  • lameness followed by loss in production, hoof trimming, medication and milk being discarded
  • difficult calvings followed by retained placentas, metritis,… resulting in cost and delayed conception
  • animals off feed and off on performance
  • calves or heifers with health challenges
  • not able to detect the onset of sickness prior to it becoming a major problem

We all have problems. First we need to identify our problems. Only after that can we plan to manage to not have them.

Systems Available

State-of-the art milking systems will measure drops in yield. Robots will do it by each quarter of the cow’s udder, and in particular, electrical conductivity of the milk at the quarter level during milking.  Parlor systems measure it at the cow level. There is a good association between electrical conductivity, somatic cell count and mastitis.

Tags will measure rumination, or cud chewing, providing an opportunity to react quickly to, say, the onset of illness or disadvantageous feeding changes, at the single-animal and herd level

Another system uses ear tags to take the surface temperature of the inside of the right ear of each transition and fresh cow every five minutes.

A passive rumen bolus system will monitor animal core temperature, which provides information for early disease detection, ovulation detection, heat stress and timing of parturition.

Another ear tag will monitor ear temperature and  head-ear movement to identify potential peripheral shock (cold extremities), which may be particularly useful for early identification of milk fever or for detecting cows moving their head or ears more when they are in heat.

Another technology will monitor lying behavior and activity. Activity monitoring is a comparatively new technology that is gaining in use for monitoring animal health including estruses.

Yes there are new systems continually becoming available but the question is how accurate are they and do their benefits out-weigh their cost? For example, $25 more profit per cows per year from using a device may not be worth it but $200 more profit per cow definitely requires serious consideration of the technology.

Plan for Profit

It is no longer good enough to not know or ignore health (that includes fertility) details on your cows. Past approaches of ‘not sweating the small health stuff’ are not appropriate as profit on today’s dairy farms depends on taking a total package approach. Remember: you need to continually looking for ways to improve; you need to decide on the limiting factors on your farm; you need to prioritize your technological enhancements; you need to capture the information accurately and economically; and you need to manage for profit.

The-Bullvine-Bottom-Line

None of this is new information to people who work with dairy cows. We all breathe a sigh of relief when a cow gets through the transition period disease free and we can look forward to a productive lactation and a confirmed pregnancy ahead. Or when a healthy calf in born that grows quickly and enters the milking herd at a young age. Obviously the first line of defence or attack is always a proactive plan to grow and have healthy, disease free, disease resistant profitable cattle. When it comes to profitable dairy cows, raising health is a good thing!
