Why Dairy Farmers Should Care About Their Cows’ Lying Time

Is your dairy farm’s productivity at risk? Learn why lying time matters for your cows’ health and welfare. Find out if your cows are getting enough rest.

Summary: Imagine, for a moment, that you are a dairy cow. Sounds strange, right? But think about it: your days revolve around eating, milking, and lying down. It’s not just about comfort; it’s about survival and productivity. Are you aware that the time cows spend lying down is a major indicator of their overall well-being, impacting everything from milk production to their risk of developing lameness? If cows don’t get enough time on soft, dry surfaces, they can become stressed, unhealthy, and less productive. The science is clear: cows need to lie down for about 10 to 12 hours a day. Yet, achieving this requires careful attention to their environment and daily routines. Factors like housing type, stall design, bedding quality, and even weather play crucial roles in determining how much time cows can rest. Farmers, understanding your cows’ lying behavior can be the key to unlocking better health and productivity on your farm. From understanding cow motivation to lie down to the spaces they are provided, and even their reproductive status, each detail affects a cow’s comfort and welfare. Dairy cow welfare is crucial for the dairy farming industry, as it directly impacts their health and productivity. Inadequate lying time can lead to health problems such as lameness and decreased milk supply. Cows are highly motivated to lie down, often foregoing other vital tasks to obtain rest. Environmental elements like housing systems, bedding quality, stall design, and weather conditions directly affect their lying time. Farmers can improve cow welfare by implementing practical recommendations such as ensuring room and comfort in stalls, using soft and dry bedding materials, streamlining milking procedures, avoiding heat during hotter months, providing shade, and ensuring adequate air movement.

  • Cows require 10 to 12 hours of lying down each day for optimal well-being.
  • Lying time affects milk production, risk of lameness, and overall cow health.
  • Environmental factors such as housing type, stall design, and bedding quality significantly influence lying time.
  • Cows are highly motivated to lie down, often at the expense of other activities like feeding.
  • Long standing periods and uncomfortable lying surfaces contribute to stress and health issues.
  • Milking routines, weather conditions, and cow standing surfaces also impact lying behavior.
  • Farmers can enhance cow comfort by ensuring spacious, clean, and well-designed resting areas.
  • Effective heat management, including shade and adequate air movement, is crucial during warmer months.

What if I told you that something as simple as lying down could significantly improve the comfort of your dairy cows? It’s an unexpected concept that underscores the importance of your role in dairy cow welfare. More than just animal care, it directly impacts your business. The time cows spend lying down profoundly affects their health and production. How can such a basic behavior be so transformative? Cows that lie down for an appropriate period experience fewer health issues, such as a lower incidence of lameness and increased milk supply. This post will explore why cows must lie down, the consequences of limited lying time, and the various factors influencing this behavior. Your understanding and actions can revolutionize your approach to dairy farming. Are you ready to make a difference?

Imagine You are a Dairy Cow on a Hot Summer Day… 

Imagine you are a dairy cow on a hot summer day… You’ve been on your feet for hours, grazing, milking, and waiting in line for your turn. Now, all you want to do is lie down and relax. Can you feel the urge? This urge to lie down is more than a preference; it’s a fundamental need for a dairy cow’s health. Understanding and empathizing with this need is crucial for effective dairy cow management.

Dairy cows are highly driven to lie down, so they may forego other vital tasks, such as eating, to obtain some rest. When laying down becomes difficult, cows show what scientists call ‘rebound lying behavior.’ This is essentially a compensatory behavior where they attempt to ‘make up’ for missed time by laying down more when they finally get the opportunity. They will make considerable efforts to locate a comfy area, even working hard to trigger machinery such as levers or gates to secure a space to lay down.

The risks are significant when cows are unable to lay down properly. Less time spent lying down may cause considerable health problems, the most noticeable of which is lameness. It is simply physics: standing exerts pressure on their hooves, which causes discomfort. Furthermore, inadequate laying time might exacerbate other stress-related issues, impacting general biological function, including milk production and sleep.

Moreover, the frustration of being unable to lie down has visible behavioral consequences. Cows may alter their weight, stride erratically, or exhibit symptoms of agitation and discomfort. This tension is more than a temporary inconvenience; it could have long-term consequences for their health and productivity. Recognizing these potential issues should motivate you to ensure your cows have adequate and comfortable lying time.

So, for dairy cows, laying time is more than simply their having some rest. It is an essential part of their health and well-being. Ensuring that cows have enough pleasant laying time is critical for their well-being and production on the farm. The next time you see a dairy cow relaxing, remember that it is not laziness; it is a necessary part of their daily routine.

What If I Told You A Cow’s Comfort Could Be Assessed By Simply Observing Lying Time? 

However, as with people, certain environmental elements directly impact how much sleep we receive, and these subtleties may make all the difference.

First, let us discuss housing systems. Cows in free-stall and tie-stall systems sleep 10 to 12 hours daily (Charlton et al., 2014; Solano et al., 2016). Freestalls provide separate resting areas for cows; overstocking may significantly diminish this time. When there are more cows than stalls, the rivalry for laying space causes many cows to spend less time resting. Fregonesi et al. (2007) discovered that cows enjoyed shorter laying periods when stocking numbers exceeded 1.2 cows per stall.

Next, the quality of the bedding must be considered. Cows prefer soft places to rest on, avoiding hard, unpleasant ones. Studies consistently demonstrate that laying times are substantially shorter on bare concrete. Cows on softer rubber mats or mattresses rested longer than bare concrete (12.3 vs. 10.4 hours/day) (Haley et al., 2001). The amount and quality of bedding are other vital considerations. Inadequate and moist bedding materials significantly diminish laying time. Cows raised in dry environments lay down more, with substantial differences shown in research when bedding included 86% dry matter vs 27% (Fregonesi et al., 2007).

Stall design also plays an important function. Sizes that do not suit cows’ normal behavior may reduce laying times. Tucker et al. (2004) found that narrow stalls had considerably shorter laying times than suitably sized ones. Cows on farms with more oversized stalls were healthier and could lie down for extended periods.

Weather conditions are another critical consideration. In warmer summer months, cows spend less time resting down. Their laying time may drop by up to 22 minutes for every one °C rise in ambient temperature (Chen et al., 2016; Tresoldi et al., 2019). Cows under great, moist circumstances also have shorter resting hours. Beef cows tend to lay down less in rain than in dry circumstances (Schütz et al., 2010). This means that cows may need additional measures during hot or rainy weather to ensure they have enough comfortable resting time.

Observing these environmental factors—housing systems, bedding quality, stall design, and weather conditions—provides cows with a pleasant resting habitat, directly influencing their well-being and productivity.

When a One-Size-Fits-All Approach Will not Do: The Nuances of Dairy Cow Lying Behavior 

When investigating dairy cows’ lying behavior, it is critical to remember that not all cows are made equal. Individual variables influence how long a cow spends lying down each day. Let us investigate some of these characteristics and comprehend the intricacies and differences among cows.

Age and Parity

You may expect aged cows to have a constant pattern while lying down, but the truth is far from obvious. The research yielded mixed findings. According to several research studies, cows with more parity (more lactations) lay down for extended periods, with variations ranging from 0.5 to 1 hour. Other studies, however, show no significant changes or slightly shorter laying durations for cows in their third or higher parities.

Changes in lactation phases complicate matters further. Recent longitudinal studies, for example, show that. In contrast, first-parity cows have shorter laying durations in early lactation; these differences fade as lactation develops. This raises crucial questions: Are these variations attributable to physical recuperation following calving, physiological adjustments during the transition phase, or even changes in milk production?

Reproductive Status.

Reproductive status has a significant influence on lying behavior. When a cow is in estrus, she spends less time laying and more time walking. Some studies reveal a 37% decrease in laying time on estrus days. This increase in activity, although significant, confuses our understanding of lying as a well-being measure. It’s important to consider the cow’s reproductive status when evaluating their lying behavior, as it can significantly affect their activity levels and resting time.

Cows also undergo significant changes around parturition. Just hours before calving, there is a substantial increase in episodes of lying; however, the overall duration of lying decreases by roughly an hour. Following parturition, attention turns to licking and feeding the calf, temporarily lowering laying time. Over time, lying time tends to rise as cows go through the early lactation period. However, this may vary greatly depending on individual and environmental circumstances.

Health Issues: Lameness and Mastitis

Health issues like lameness and mastitis are essential predictors of lying. Lame cows spend more time lying down than their healthy counterparts, and the discrepancies have been extensively established in various studies. This increase in lying time in lame cows presumably reduces pain and discomfort. However, it also complicates the interpretation of lying time as a straightforward wellness metric.

Mastitis-infected cows, on the other hand, lay down less often. This might be due to the discomfort caused by an irritated udder, which makes lying down difficult. It emphasizes that although more excellent laying time usually indicates comfort, it may also indicate a health issue that requires rapid treatment.

Interpreting variations

Given these difficulties, using laying time to measure dairy cow well-being requires a careful approach. Factors such as parity, reproductive state, and health condition substantially impact lying behavior, emphasizing the need for a comprehensive examination. For example, although a cow laying down less during estrus is regular and anticipated, decreased lying time owing to insufficient bedding or excessive milking frequency may signal welfare difficulties.

Individual cows have distinct needs and reactions, underscoring the need for individualized welfare evaluations. Understanding why and in what context these differences occur is essential; it is not simply how many hours people lay down that matters. By considering these individual-specific aspects, dairy producers may better attend to each cow’s welfare, assuring production and quality of life.

The Hidden Cost of Your Dairy Cow’s Rest: How Inadequate Lying Time Threatens Health and Productivity 

Inadequate lying time has a substantial influence on the health and production of dairy cows. The increased likelihood of lameness is one of the most pressing concerns. According to research, cows confined in unpleasant laying conditions are more prone to acquire lameness. Leonard et al. (1994) found that “lower lying times in heifers preceded the onset of claw lesions,” suggesting a clear link between insufficient lying time and foot health problems. Furthermore, Cook et al. (2004) discovered that “housing conditions that differ in the prevalence of lameness do not always differ in the time that the cows spend lying down,” indicating that numerous variables, including lying time, contribute to the beginning of lameness.

Aside from physical health, stress reactions are a crucial consequence. Studies have demonstrated that suboptimal sleeping circumstances and forced standing might cause physiological stress reactions. For example, Fisher et al. (2003) found that calves forced to stand on hard surfaces had “higher fecal glucocorticoid metabolite concentrations,” suggesting increased stress. Variations in HPA (Hypothalamo-Pituitary-Adrenal) axis activity owing to insufficient laying time were also noted, with Munksgaard et al. (1999) discovering altered cortisol responses in bulls exposed to extended standing.

The effects extend to milk production as well. Although the direct impacts of laying time on milk supply are not always visible, cow welfare and feeding behavior affect milk output. Munksgaard et al. (2005) observed that when cows had less time to lie down and eat, it resulted in “decreased feed intake and weight loss,” reducing their milk production capacity. Krawczel et al. (2012) found no significant changes in milk output when lying time was adjusted using characteristics such as stall width, suggesting that the link between lying time and milk production is complicated and mediated by other welfare factors.

The research shows that enough laying time is crucial for dairy cows’ physical health and productivity. As Cook (2020) puts it: “A direct and simple effect of altered lying time on milk yield seems unlikely; however, the average lying times were above ten h/d in these experiments.”

Farmers, Are You Wondering How You Can Make Your Cows More Comfortable and Improve Their Overall Welfare? 

Farmers, do you want to know how to make your cows more comfortable and increase their general welfare? Let us start with some practical recommendations you can implement right now to improve the laying conditions in your herd.

  1. Improve Housing: Comfortable and Spacious Design. When it comes to housing, consider both room and comfort. Dairy cows thrive in situations with plenty of room to move and lie down. In tie-stall and free-stall systems, making sure stalls are the right size—both in width and length—can significantly impact. Consider your cows’ measurements and make sure the stalls are not too tight or loose.
  2. Bedding: Soft and dry is critical. Not all bedding materials are made equally. Straw, wood shavings, sand, and rubber matting provide more comfort than bare concrete. Furthermore, it is essential to consider the kind and quantity of bedding. Ensure that the bedding is deep enough for the cows to rest comfortably. To keep bedding dry, check it regularly and refill it as needed. Wet and uneven bedding may hinder cows from resting down.
  3. Time Management: Smart Feeding and MilkingFeeding and milking are non-negotiable duties, but they do not have to reduce your cows’ laying time significantly. Streamline your milking procedure by limiting milking and waiting periods to three hours per day. When feeding, spread meals so your cows don’t have to eat too long. The idea is to divide their time between eating, milking, and resting.
  4. Climate Control: Avoid the heat during the hotter months; cows stand more to cool off. Combat this by improving barn ventilation and utilizing fans or misting systems to keep your cows cool. Provide shade and ensure there is enough air movement. Heat stress not only shortens sleep but also impacts health and productivity.
  5. Regular assessments: Monitor and adjust. Finally, make it a practice to check your cows’ laying habits. Technical methods, such as automatic loggers, can be used to monitor how much time they spend lying down. This information may help you make educated judgments and modifications to enhance circumstances continuously.

These methods will improve your cows’ well-being and increase production and agricultural efficiency. Remember that a comfortable cow is a productive cow.

The Bottom Line

The amount of time your dairy cows spend lying down dramatically impacts their health. As we have seen, laying time is more than simply a sign of comfort; it is also necessary to avoid serious health problems like lameness and ensure cows can execute essential biological tasks like rumination and sleep. The contrast between cows in free-stall and tie-stall systems, which lay down for 10-12 hours per day, and those in bedded packs, dry lots, and pastures, which rest for around 9 hours, demonstrates how housing and management influence this behavior.

The motive for cows to lay down is essential. Studies reveal that if forced to stand for an extended time, they would lower their feeding time and participate in rebound lying. When you do not get enough sleep, you will feel more frustrated and have worse health. These findings remind us that comfort does not come from laying surfaces alone and general management techniques like milking and feeding schedules.

So what should you do? Begin by frequently checking your cows to ensure they have enough rest time. Determine how long they lay down and identify any environmental or managerial elements that may shorten this time. If your cows rest for fewer than 10-12 hours daily, it is time for a checkup. Consider adding softer bedding, changing feeding and milking timings, or enhancing the overall stall arrangement.

Reflect on your existing practices: Do your cows spend lengthy amounts of time standing on unpleasant surfaces? Are they spending too much time in headlocks or when milking? Remember that their comfort directly affects their productivity and health. Prioritizing appropriate laying time improves their well-being and may increase your farm’s output. Are you prepared to make the required modifications to guarantee that your cows enjoy their best lives?

Why ALL Dairy Farmers Should Get Excited About Proof Day!

For the 1% of breeders who deal in seed stock Proof Days are like Christmas 3x times a year.  But for the remaining 99% of dairy breeders proof days, the days when the latest Genetic Evaluations are released, are not that big a deal.  But they should be.

The following are three reasons all dairy producers should be checking out the latest genetic evaluations.

All producers should be using the best genetics possible

Analysis conducted as a cooperative effort between Canadian Dairy Network (CDN) and the milk-recording agency in Québec, Valacta, examined the association between the average profit per cow at the herd level and the genetic potential of the herd for various traits.

dairyprofit

Figure 1 shows the relationship between the average LPI and the average profit per cow per day in each herd studied. While there are some exceptions to the rule, the dark line in the graph reflects the average relationship across the LPI scale, which indicates that herds with higher average LPI levels of their cows also have higher profit values. This positive correlation between LPI and profit clearly shows that genetics is a significant contributing factor but that management also plays a major role. On average, for every 100-point difference in LPI at the herd level there is an increase in profit per cow per year of $50, which accumulates from year to year. From a sire selection perspective, this equivalence translates to a difference of $50 more profit per daughter per year for every 200-point difference in the sire’s LPI value.  Based on a 50% conception rate, that would indicate that the semen from a sire who is 400 LPI points higher than the average sire, should cost $50 more.  Applying this to the current sires available, by using a sire such as AltaRazor who has an LPI of +3038 you will generate and extra $187.50 compared to a sire with an LPI of 1500.  This is from direct daughter profitably and does not even factor in the increased performance of any progeny this cow would produce.  So then investing $50 to $100 more for semen that will deliver over $180 in return is certainly a profitable decision even for commercial milk producers.

The Grass Is Always Greener on the Other Side of the Fence

I often hear many producers quote the minimum levels for certain traits that they are willing to use.  The challenge with that is while this approach is great for setting basic criteria, it fails to look at how these sires compare to other sires.  By using “any” sire that meets their criteria they are missing out on maximizing the genetics gain, and therefore the profitability of their herd.  As demonstrated above setting a minimum threshold, instead of going for maximum return, is leaving dollars on the table, and not in the milk check.  Then there is the case where some milk producers prefer to deal with only one semen sales representative or A.I. company.  No A.I. company has all the best sires (Read more: Stud Wars: Episode II – April 2014), so by employing this practices any savings or efficiencies you gain from negations, are negated by the amount you are costing yourself in loss of genetic potential.  (Read more: Rumors, Lies, and other stuff Salesmen will tell you and Are There Too Many Semen Salesmen Coming In The Lane?)

Are You Sure You Are Getting What You Pay For?

With the latest reports indicating that genomic young sire use is approaching 60% in North America, many producers have embraced genomics in a significant way (Read more: Why 84% of Dairy Breeders Will Soon Be Using Genomic Sires!).  I have even come across herds that have gone to 100% genomic young sire use.  With such a heavy usage of sires that are 60-70% reliable, are you sure that the sires that you are using are delivering on the other end?  A great way to check this is to see how the sires you are investing in, are doing when they receive their official daughter proof.  Sure that may not mean that you go back and use these sires once they are proven, but it does help you get a better understanding of the reliability of the genetics that you have invested in.

The Bullvine Bottom Line

I am not saying that all dairy producers should be waiting with baited breath at 8 am on proof day.  However, there is certainly value in taking the time to check out the latest sire evaluations, to see how the sires you have been using are performing and what other sires are out there that could help you increase the profitability of your herd.  No matter what your management style, there are certainly enough reasons for you to get excited on proof day.

Don’t Blame Your Cows for Lack of Production…

Maybe you’ve seen this happen.  You’re so confident in yourself and your milking team that you consciously or unconsciously have started skipping a few steps.  Or, you have gradually taken on new staff – perhaps a family member or someone selected from the wider community — and you assumed that you didn’t need to review or test their understanding of milking basics because, after all, they know all about it. Then suddenly you’re presented with proof of low milk production and you don’t know how it happened. It just sneaks up on you. Fortunately there’s always a reason.  In this case, it’s up to you to find both the cause and the solution to declining milk production.

Are Your Records Measuring Up?

You have to start with your records.  If you cannot clearly identify the problem, you will find it doubly hard to come up with a way to solve it. Ideally, your milking team is well aware of the benchmarks you are targeting.  Check your records and see if gaps have developed in the achieving the following goals:

  • SCC UNDER 200,000. Evaluate the herd for a high incidence of subclinical or clinical mastitis.
  • CMT: 70% of the herd with linear score of 1 and 2
  • TEAT HEATH: 80% of the herd with no teat end problems. Erosion, eversion, cuts or sores dealt with on a scheduled basis.
  • AVERAGE DAILY PRODUCTION: minimum of 70-75 pounds of 4% fat corrected milk.
  • PEAK PRODUCTION: Set parameters so that you know if heifers and second lactation or older animals are reaching peak production.
  • LACTATION LENGTH: 290 to 310 days with an average length of 296. Anything less than 270 days is considered a short lactation.
  • DRY PERIOD:  Check to see if dry cows have had a dry period of not more than 6 weeks.

Testing. Testing.

  1. Re-check milking procedures. Double check for efficient milk practices.
  2. Take milk samples and run culture and sensitivity tests.
  3. Screen rations or individual feeds for molds and mycotoxins.
  4. Test milking equipment. Poor letdown can be caused by extremes in vacuum.
  5. Test rations and forages to identify deficiencies or imbalances.
  6. Test to find toxicities from chemicals, fluoride and other chemicals.
  7. Test water for impurities or anything that might lower intake.
  8. Stray voltage should be examined when other obvious factors appear normal.

There are obviously other tests that can be performed based on your individual goals and strategies.  The point is not the number of tests. It is about the quality of the data that you have for informed decision making.

Don’t Assume You Always “Know” Best of “Do” Best.

Faulty milking practices always contribute to lower milk peaks and shorter lactations.

  1. Let-down: Poor milk letdown obviously has a negative effect on milk production.  There are many causes that can be determined and managed.  Some cows need a second stimulation to fully let down their milk.  This needs to be recognized, recorded and allowed-for in the milking routine SOP.
  2. Timing:
  3. Too soon or Too Late. When the milking machine is attached is very important.  After proper prepping, milking should be within 0.5 to 2 minutes. Being put on too soon or too late after preparation causes problems.
  4. Too long. When the milking system requires more than six minutes of machine time per cow, problems can arise.
  5. Sanitation:

In the dairy business, you must keep constant vigilance to avoid bacteria.  You don’t want it to infect the milking cows.  You don’t want it in the milk. It’s false economy to save time or money by skipping cleaning procedures.  In the end, you could be facing a problem that is not only hard to eradicate once it has set it, but in some cases could mean the loss of cows.

Back to Basics to Turn Around Low Milk Production

Now that you have some numbers to work with, it’s time to go back to the beginning. It’s like baseball, which I love.  Batters (especially the good ones) are known for stripping down their swing and rebuilding it. However, the rebuild has to have a foundation.  It’s not enough to continuously tweak something here, and something else there just because your stats are “suddenly” showing that you are striking out more often. When you do that, you get so far from the foundation that it becomes all miss and no hits!  Batters (and their coaches) start at the beginning, rebuilding piece by piece, doing the hard work of getting back to the basics. They do the hard work of rebuilding by grinding through what was once simple, all over again.

Here’s the Secret

Make sure you have your Standard Operating Procedures in place, and that everyone knows what is expected. The secret to success isn’t about making your own rules.  It’s all about rules that are effective and that everyone completes properly – every single day – exactly the same way.  On dairy operations, there is a risk of slippage (or suddenly being faced with low production) the moment we think we no longer need the foundational elements that made us successful milk producers in the first place.

Nine Basic Steps that should be Part of Your Standard Milking Procedures

  1. Dry-wipe dirt and debris from the first cow’s udder.
  2. Pre-dip all four teats with the green dip cup.
  3. Strip two squirts of milk from each teat and observe for abnormal milk. (*You should have a SOP in place for dealing with abnormal milk.)
  4. Return to the first cow and thoroughly wipe with a clean towel.
  5. Attach the unit to the first cow and adjust.
  6. Repeat steps 5 and 6 with the second and third cows in the side.
  7. Begin at step 1 with the fourth cow on the side and repeat procedure with each group of 3 cows until all 12 units are attached.
  8. When all units have detached, post dip all cows and release.

Once again the perfect SOP is not necessarily these exact eight steps.  The best SOP for milking procedures at your dairy is the one that is developed by your milking team, practiced, revised and performed daily, and that gets the best production from the milking herd.  No surprises!

Eat Well! Live Long! Milk Often!

As discussed so far, there are many little things that can add up to the significant problem of declining milk production. If none of the preceding scenarios are contributing to your situation, maybe it is time to look at the age of your cattle, the nutrition provided for your herd and finally, milking frequency.  Consider this three-point proposition: 1. Cows who live longer milk more. 2. Cows who eat more give more milk. 3. Cows who are milked more often give more milk.  After all, cows need optimum health and energy to produce to optimum levels. With the right nutrition in place, then check your system to reduce the stress and strain.  More frequent milking can be another way to enhance udder health, increase production and extend the milking life of your cows.

Time to Test Again!

Perhaps you have come full circle in your strategic review, with all of your staff involved, and you are certain that all the SOP procedures are being followed by all milking staff.  At this point, any problems in milking performance that are discovered must be a result of a more severe deficiency either in the design of your SOPs or with the health of your herd.  Call in your consultants: nutritionist, veterinarians, feed suppliers or other dairy peers whose opinion and objective viewpoint can give you a different perspective. It’s never too late and getting the best data is the place to start. Information is the key.  So once again in addition to the testing previously outlined, the following information should be tracked and posted:

  • Somatic cell counts
  • Standard plate counts
  • Preliminary incubation counts

The Bullvine Bottom Line

Don’t blame your cows. Consistently good milk production is all about doing the simple things. It is built on the foundation elements that we know we should do, over and over, day after day. Success means following a few of the most simple rules and following them correctly and consistently.  It isn’t glamorous but perfecting the basics works whether you’re goal is hitting home runs or milking a high producing dairy herd. Remember don’t blame your cows for lack of production…you’re the problem, and you can be fixed!

The Lost Art of Dairy Cow Stockmanship. When Push Comes to Nudge.

The expression “until the cows come home” can mean one of two things.  Either the cows are expected to come home for milking and will be there or else it can mean waiting a very, very long time.  Getting aligned with the routine of these creatures of habit is a daily activity on dairy farms and when it moves along smoothly it`s great but too often the opposite is true and it becomes a daily frustration. When cows refuse to move easily from one location to another or one activity to another, it costs time and money.  Both bovine and human stress levels can skyrocket with a corresponding rise in injuries.

It`s Time to Get A Handle on Handling

When day to day interaction between cows and handlers results in injuries to either party there are lost workdays and decreased milk production. It’s easy to point the finger of blame at human handlers. However, for this interaction to work successfully both sides have to be calm.  Handlers need to calm plus reassuring.  As a result, cows will be calm plus comfortable.

Is Your Cattle Comfort Checklist as Ticked Off as Your Cows?

  • Cows behave unnaturally and stand or lie down uneasily.
  • Patches of rubbed-off hair and injuries to hocks and knees indicate that, when rising or lying down, cows are repeatedly rubbing on stall partitions or neck rails.
  • When cows are moving, they have an unsteady gait.  If they are walking slowly, or timidly, with rear feet spread wide, this is a sign of poor traction and that something is negatively affecting their confidence in their footing.
  • Mastitis, sore feet and swollen hocks are also signs that handling needs attention.
  • If more than 20 percent of the cows defecate in the parlor, the cause needs to be determined.
  • All concrete should be grooved to make it less slippery.
  • Check stray voltage
  • Confirm that milkers are calm and reassuring as they handle and milk cows.
  • Maintain routine contact with animals to retain familiarity

Quick Changes … Get Cow Comfort Corrected

Cow Kindness not Over-Rated!

Temple Grandin, remarkable advocate of animal caretaking, Karen Lancaster, from England, and other experts who consult and provide cow handling seminars are agreed on one basic premise. “When the cows are happy, we know they eat more, when they eat more they make more milk.” Results report that cow comfort can mean the difference of several thousand pounds of rolling herd average milk production between two herds of similar genetics and rations.  Simply upgrading a cow’s surroundings to light, clean and airy can radically move the following five performance parameters in the right direction.

  • Production
  • Performance
  • Efficiency
  • Safety
  • Animal Welfare
  • Quality of life

It shouldn’t be a surprise to learn that light, clean and airy can improve the same five criteria for the human dairy staff as well: production; performance; efficiency; safety; personal welfare and quality of work-life.

Put Yourself in the Cow’s Position

When we are consulting in business or trying to improve our personal working conditions, we often advise peers and clients to walk a mile in each other’s shoes. It isn’t bad advice when considering the best ways to handle our bovine workforce. Imagine yourself in the milking set up, the stall or the alleyways and pastures in between.  Consider the logistics of size and ask yourself if this would be an area you would want to walk, sleep or work hard in? Cold, dark and damp are probably NOT the three top features you would be seeking out.

If you are eager to remind me that some cows are just “difficult,” perhaps it’s time to consider the same label can be applied to complaining cow handlers.  I continue to be amazed that people who wouldn’t think of yelling at each other, or pushing or shoving, find that style an easy one to adopt when moving calves, heifers or cows.

One Video is Worth a 1000 Words

You can find a lot of enlightening advice from online videos on cattle handling.


No man or animal likes surprises or walking (or being pushed) into dangerous situations and it is important to give consideration to the actual sightlines of the animals.  When calves and cows learn to trust that you have their interests at heart, they will be ready and responsive to your commands.

Cattle are creatures of habit and they have long memories.  It’s a good idea to “start the way you want to end.”  From first contact as calves … to final turnout to greener pastures… your interaction with herd and individuals should be calm, consistent and kind.

Talk Softly and DON’T Carry a Big Stick!

Dr. Joep Driessen, Director/Owner of CowSignals Training Company, says research shows that women get 10 percent more milk out of cows.” He suggests that farmers modulate their barn voices to more soothing tones. “Women are more gentle and cows like the soft voice of the women more.”  All cow handling consultants insist that shouting at cows won’t help, because loud human voices stress cows even more than being physically slapped.
Curt Pate, well known for low stress cattle handling, has a list of tips which include the following:

  1. Make sure the cattle can see you.
  2. Don’t make sharp, loud noises.
  3. Don’t rush the animals.
  4. Use cattle prods and other equipment as little as possible.

“Farmers who don’t follow these guidelines and rush their animals harass them with noise or prod them unnecessarily risk raising their stress, increasing sickness and lowering production,” says Pate.

When trying to move cows, the handler needs be aware of his/her timing, angle, speed and direction of approach.

Obviously, the handler has to plan ahead where he/she wants to move the cows so that clear signals for the direction can be given.

If the handler can’t see a cow’s eye, the cow can’t see the handler and so the cow won’t be able to respond to the handler’s signals.

Part of the timing during cattle handling is to give cows time to react to the handler’s signals and to release the pressure once cows are starting to do what you asked of them.

Who Needs the Training First? Cows? Handlers?

Many times a situation on the dairy farm has become so repetitive that the only interaction certain individuals have with the cows is negative. It is necessary to see yourself as part of a team that involves the cows.  Good behavior should be rewarded and repeated.

An interesting finding of one survey was that herds that had previous stockmanship training tended to have about 1,760 pounds higher rolling herd average than herds that did not – even after accounting for the herd size.

Studies have shown that if cows are stressed, adrenalin will diminish the oxytocin response and their milk let down will be impaired. As a result, cows will not milk out and producers will lose milk.  In addition, stressed cows are more likely to defecate or urinate as well as kick in the parlor – none of which are particularly pleasant for the people working in the parlor and will likely affect their attitude towards work, as well.

Regularly revisit animal handling protocols to determine if updates are needed.

DIY or Experts … Who do You Turn to?

Training is traditionally done by herd owners or managers who have learned cattle handling predominantly from family members or by trial-and-error. However, today, in particular producers of larger farms (>200 milking cows), managers seek out low-stress handling training seminars to learn more about best cattle handling practices.  There is an abundance of resources to take your herd handling to the next level.  Online articles and videos are available from world renowned experts such as Temple Grandin and Dr. Joep Driessen.   Several well-respected animal handlers are available for onsite farm demonstrations or seminars for groups. Of course, you can send out a call for help and your Facebook, Twitter and LinkedIn connections may be ready to give you help.

Bullvine Bottom Line

There are many good reasons to improve, modify and make over your cattle handling techniques.  With daily opportunities for improvement, it’s safe to say that, although the practice may not make perfect, it can forge a willing and productive partnership between cows and farm staff.

Now everyone can handle that!

There`s Rumen for Improvement. Happy Bugs=Happy Cows!

“A nutritionist and a dairy farmer walk up to a feedbunk.” It sounds like the start of a lame joke, but with shrinking margins and rising input costs feeding dairy cattle is no laughing matter.  It would be really nice if the pastoral idyll of rows of cows contentedly chewing their cud was achievable simply by filling a feedbunk.  However, not only is this picture not the simple equation of feed in equaling milk out, but in actual fact depends more on what you feed the bugs in your cows’ stomachs than it does on what you think you’re feeding the cows.  Ruminants are hosts to numerous microbes and the microbes need to survive and multiply in order for milk to be produced.  So to put it simply, “If you want better rumen health, you need better rumen bugs!”

From Tongue to Dung – Travelling the Fermentation Road

The whole process is one of digestion. Digestion begins when cows draw feed into their mouths with their tongues.  Each mouthful passes into the rumen, flows to the abomasums and then through the small intestine, the large intestine and then out!

For the most part, this entire process is unseen to the human eye.  Except if there’s a problem (such as a twisted abomasums that can be felt by touching the cow’s side) or, when it is finished and the manure gives visual clues to issues.  Of course, out of sight out of mind isn’t the best management tool when you’re trying to effectively monitor or set up dairy cattle diets.  Nutritionists and veterinarians use scientific methods to study the feed and the bugs.  Fortunately the tools being used are continually evolving, as specialist can make the rumen mystery more manageable.  Using lab analysis, ingredient evaluation and computer programs they measure, calculate, forecast and establish precise diets, customized for the dairy cow and the particular operation.

Set Goals and Test, Test, Test

The primary goal of a sound, profitable dairy feeding program is to convert forages into milk.  With feed costs representing 50 to 60 percent of the cost of producing milk, knowing the nutrient content is very important from an economic perspective.  All forages which will be fed to milking cows, heifers and dry cows need to be tested.  All lots of hay should be sampled using a hay probe on 10 or more bales of hay.  Sampling one or two bales is not an accurate way to sample a lot.  A `lot ‘of hay is defined as those bales which were harvested from the same field and cutting.  Your local feed company or extension agent can help you get your forages tested.  Testing forages and balancing rations for heifers and dry cows is critical in order to get heifers to grow efficiently and to prevent dry cows from losing or gaining too much weight.

Every Body Works Better on a Schedule

As we turn our attention to focus on fermentation we have to consider the effect of timing.  Cows and rumen bugs are both creatures of habit.  We all know how dairy cows get into a routine and expect to be milked at the same time every day.  A variation of much more than 10 minutes causes stress.  If feed is expected every day at 10 am, 10:45 will further upset the routine.  The goal is that every day is exactly like the day before and the day after.  Consistency is good not only for the cows but for the rumen bugs too.

Don’t Upset Your Cows or Their Rumens

Rather than upset the rumen vat with constant changes, subpar feed or feed that is presented erratically, it is important for rumen health to make diet changes gradually.  If daily handling is calm, routine and without overcrowding in feed and resting areas, the daily digestion process will be stress free and more likely to be effective. Rumen fermentation can be altered by stresses.  Spoiled silage has a dramatic impact on rumen fermentation and dry matter intake.  Optimum rumen fermentation requires consistent nutrient supply.  If excess spoiled feed is consumed, there is a distinct likelihood that desirable rumen bugs are being killed off.  Even minor changes can have a dramatic effect on the numbers of microbes and even cause a particular bug to become more dominant.  This becomes a domino effect that could result in poor digestion and other problems.

If She is Not Making Milk Targets, You haven’t fed Her Rumen

Too often dairy managers confuse feeding the cow and feeding the rumen. Farmers should work closely with their nutritionist in designing a feeding program so that the nutrient needs of the rumen microbes are met in order for the cow to produce milk.  Once the feeding program has been designed, implementing the feeding program becomes the next critical step.  The final measure of the diet is determined when milk is produced. If the goal was to produce 80 pounds of milk and you only get 70 pounds, there is a discrepancy somewhere and it must be found.

As rumen modeling becomes a more and more exact science, it is important to remember that no model will correct for poor management.

New Ways to Monitor Microbes

As in other areas of dairy cattle management, the rumen is benefitting from new technologies. Gene sequencing and measurement of the expression of genes (genomics), proteins (proteomics) and metabolites (metabolomics) can now be used to better differentiate microbe species in the rumen.  Using these tools it is reported that the rumen contains over 7,000 bacterial and 1,500 archael (single-celled but distinct from bacteria) species.  There are also numerous protozoa, fungi and bacteriophages.  Studying these organisms by use of new approaches is making it easier to understand the physical structure of different ingredients in the rumen and how they impact rumen function.  The payoff is better health and more efficient use of dietary nutrients.  All in all the process is complicated and speedy and analysis needs to provide the best information before the fermentable ingredients escape the rumen.

Happy Bugs Happy Cows

Maximizing rumen function means we work to maximize microbial activity.  It takes energy to produce milk.  Extracting as much energy as possible from the fiber components (NDF digestibility) is the goal. It is necessary to maximize microbial protein production through microbial growth (high quality amino acid supply). For milk production and profitability the goal is to formulate diets that utilize the rumen to the fullest extent.  Supplying the right nutrients, calmly and consistently is the formula for contented milk-producing cows.  Cud chewing is the external sign but it takes good planning, delivery, monitoring and testing to confirm that the “healthy bugs, healthy cows” two step is at work in your herd.

The Bullvine Bottom Line

Happy Bugs.  Healthy Cows.  More milk.  Fewer vet visits.   From the feedbunk to the bank, improved rumen performance putting more dollars on YOUR Bottom Line

Feed Efficiency: The Money Saver

Fed up? Losing money? Start Tracking Feed Efficiency. The current lack of forages for dairy cattle in North America and high grain prices globally has brought feed front and center on most dairymen’s radar screen. Since for most herds feed costs vary between 50% to 60 % of the dairy’s operational costs, the current higher costs are narrowing on-farm margins. In some cases it has resulted in farms downsizing their milking herd, selling off their heifer herd and for some farms an exit from the dairy business. To say the least dairy farmers are having to address something foreign to most of them – the amount and cost of the feed their herd is consuming.

New Territory for Dairy Farmers

Given that dairy cattle breeding, to a very large extent, has ignore any genetic aspects to a cow’s ability to convert feed into milk, the idea of culling cows that do not convert well is an unheard of practice. Seeing that this subject is new to most breeders, The Bullvine decided to delve a little deeper into what is known and what investigation is underway when it comes to the efficiency with which cows convert their feed to products humans can consume.

Feed In. Dollars Out. It’s Hard to Capture FIDO.

It is costly and time consuming to capture individual cow feed consumption, so producers and their feed advisors have taken the approach of feeding the herd or groups within the herd and monitoring the production, feeds costs and the returns over feed costs. Only in research herds has there been any attention paid to individual cows and their efficiency of conversion or return over feed cost.  And then only for cows on feed composition trials and nothing on a cow or sire’s daughters genetic merit for feed conversion. So to put it simply the industry has said – feed them more, balance the diet differently, add some micronutrients, have adequate fibre in the diet, etc. because we have not been able to address the cow’s genetic ability to convert feed to milk.

What We Know about What’s Eating You

Some facts about feeds, feeding animals and feed costs include:

  • The poultry and swine industries have paid considerable attention, for quite some time now, to feed conversion / feed efficiency. With much success especially in      poultry meat industries. In beef and sheep feed conversion for animals being finished in feedlots is an important profit factor.
  • In dairy cattle, feed conversion ability includes all aspects – feeding for growth, production and maintenance.  We do not always think about the extra cost to grow heifers larger or to maintain a large versus a medium sized cow. By the way the Net Merit index does include a 6% weighting on cow size. And it is a negative weighting so larger cows are penalized for their extra size. So if you have been using the Net Merit index you will already be indirectly breeding for feed efficiency.
  • Level of milk production very much depends on the amount of feed consumed by a cow (commonly known as Dry Matter Intake). But we do not know the degree of correlation between volume consumed and feed efficiency.
  • Recent cost studies show that milking cow feed costs on individual farms vary from 20 to 35% of milk revenue. That variation is significant! So the opportunity to make progress in returns over feed costs is out there.
  • Given the wide variety of feeds and feed practices on dairy operations, an average feed cost per milking cow per day on individual farms can be anywhere from $4.00 to $8.00.
  • Every day dairy farmers have happen but do not monitor or comprehend differences in their cows’ ability to convert their diet into milk revenue. Depending on lactation numbers and stage of lactation a cow consumes 1 kg of dry matter to producer between 0.8 kg and 1.8 kgs of fat or energy corrected milk. Differences in milk, fat and protein production are monitored on-farm however cow differences in feed conversion efficiency are not.

Measuring the Future: You are What THEY Eat

Farmers and their nutritional advisors will continue to fine-tune the diets of cows. That’s a given. Gains in the returns over feed costs will be made by fine tuning diets and by adjusting the management and environments for cow and heifers.

However if the swine and poultry industries have been able to genetically enhance their species’ ability to convert feeds to meat or eggs, then is there not an opportunity for dairy cattle to also be bred for feed conversion efficiency?

It should be possible to breed for heifers that grow more efficiently and cows that convert feeds more efficiently into the milk needed to produce the products consumers want and will buy. If through more efficient milk cows there could be $0.33 more profit per cow per day, which amounts to an extra net income of $25,550 per year for a 200 cow milking herd. Nothing to be sneezed at.

From a Pile of Feed to a Pail of Milk?  Where’s the Genetics DATA?

However the challenge remains how to the get data for use in on-farm decision making and for determining the genetic difference between animals and bloodlines for feed efficiency. Well in fact there are some keen researchers in the United States, the Netherlands, the United Kingdom and Australia in association with countries with national data bases used for genetic evaluation addressing this challenge. Currently they have studies underway to measure feed intake and cow outputs for cows on research trails. After obtaining the data they will correlate the efficiency results with the DNA (snips) makeup of the cows. In the USA alone there will be over 8,000 cows currently being studied.

Within a year the dairy industry can expect to see some preliminary results of this research work. But genomic indexes will only be the start. I expect that on-farm data capture software and systems will become available to measure a cow’s feed intake. The data from such systems will have value both at the farm level and at the genetic evaluation level.

The Bullvine Bottom Line

Stay tuned for what will be new genetic evaluations and animal genomic indexes for feed conversion efficiency. It could take up to a decade for there to be accurate indexes and wide use made of the indexes but it will come fast once the basics building blocks are in place. Even a 5% gain in feed conversion efficiency in dairy cattle will be worth billions of dollars annually to the global dairy industry. Once again opportunity knocks at our doors.
