Sixty percent of a dairy cow’s diet is forage. With so much of the diet dependent on the nutrients a cow receives from forage, it is important to make sure the crop reaches its nutrient and energy potential. Nitrogen, phosphorus and potassium, the major components of fertilizer, are essential for soil nutrient content and are controlled by pH. We test and fertilize for these nutrients regularly, and they are often the first place we look for a solution if a problem arises in crop health.

However, critical elements — like calcium, magnesium, and sulfur — are often seen as secondary in importance in terms of soil content, and, in turn, plant health. For example, with current industry practices, recent findings show that sulfur deficiency of 10 to 20 pounds per acre is common in much of the United States. Of these elements, sulfur in particular might be the missing piece in your forage puzzle as it increases nutrient quality and aids in balancing the microflora in the rumen.

What is sulfur?  

Sulfur is one of the 17 elements essential to crop production. This is because, according to the International Plant Nutrition Institute, plants almost exclusively use sulfate as their primary source of nutrition. It can be found in high levels in salt domes and volcanic deposits, typically in its elemental form. But it is also present in almost all soil types in smaller quantities.

Plants receive sulfur through two primary mediums:

• Soil: The sulfur found in soil is typically organic sulfate that has been converted from elemental sulfur by soil bacteria. Ninety-five percent of plant sulfur uptake is in the organic form of sulfate.

• Air: Inorganic sulfur dioxide is often absorbed through the leaves and stoma.  

What role does sulfur play in forage plant and dairy cow processes?

Required by both plants and animals, sulfur appears in every living cell and is essential for the synthesis of certain amino acids and proteins.

A deficiency of sulfur in the soil can lead to deficiencies in the cow. Nutritionists recommend 0.2 percent of sulfur or sulfate in the diet of cattle, and ensuring your forage has enough sulfur is the easiest and most cost-effective way to manage sulfur requirements for the ration. Most of the dietary sulfur required by the cow is actually utilized by the rumen microbes for amino acid production. By feeding the microbes, the cow can produce amino acids, enzymes and proteins that then contribute to cow health, milk production and quality.

Not only will the sulfate aid the cow, but plants use sulfate for chlorophyll formation, which contributes to higher sugar content and nutrients, resulting in greener, fuller foliage.

What does our current sulfur landscape look like?

In recent years, there has been a decrease in soil sulfur content as well as an increased demand on the soil for higher crop yields, and the fact that many fertilizers contain little to no sulfur is the primary reason for our current depletion of sulfur in the top soil. Secondary causes include erosion and mineralization.

How to recognize a sulfur deficiency

Since high-yielding crops often don’t receive adequate amounts of sulfur or receive it at inopportune times, it is important to be able to recognize a sulfur deficiency. Thankfully, if presented in its organic form, sulfate can quickly be absorbed in two to three days, which helps avoid leaching as you fertilize. If you notice some of the following signs of sulfate deficiency, it is recommended to provide a sulfur treatment two to four days before cutting forage to increase chlorophyll, resulting in a fuller, energy-rich harvest.  This short-term solution can be done by applying biostimulant products, as a sulfur application would need to take place much earlier in order to keep the plant healthy and growing well. Signs of sulfur deficiency include:

• Yellowing of young growth; yellowing of old growth indicates a nitrogen shortage.

• Curling of young leaves.

• Diminished foliage.

Although sulfur is present in the soil, it is often below recommended standards. Furthermore, in its inorganic sulfur state, it cannot be properly taken up by the plant until it has been converted to organic sulfate. By checking your forage crop for sulfur deficiency and treating as needed, you can increase the sugar and nutrient quality of your forage and provide sulfur to your herd to support rumen microflora health.

Big data is ready for the farm. But is the farm ready for big data?

84 percent of U.S. farmers who responded to a recent Stratus Ag Research survey said they have high-tech equipment that captures reams of data from livestock, planting, harvesting or crop protection operations. Yet, only 42 percent of them are transferring this information to a field data management software program for further analysis. 

The question is: How can producers harness all of this information to drive efficiency and profitability once it has been collected?

KEENAN, a technological entrepreneur of diet feeders, stepped up to this challenge by expanding into farm data analysis with InTouch technology, which delivers solutions on-farm in real time.

“We've been involved with the internet of things (IoT) since about 2011,” said Conan Condon, director of KEENAN’s InTouch system. “At that stage, there wasn't much connectivity. There were about 12 million connected devices. Today, there are about 6.4 billion connected devices.” 

At present, more than 2,000 livestock operations, ranging in size from tens to thousands of cows, use the InTouch system, a live review and support service that helps producers apply actionable intelligence to their operations, giving them the benefit of KEENAN’s access to data on more than 1.3 million monitored cows.

InTouch technology: Acting on data today

KEENAN InTouch is a simple, cloud-based communications platform that offers real-time performance monitoring. The system allows for all feed ingredients to be added to the diet feeder in consistent orders and ratios, thereby promoting feeding consistency and improving livestock performance and profitability.  

​

Producers are looking for easy alternatives to interpreting and actioning data. InTouch supports that process, as data is automatically transferred and received after completion of every load. Not only are paperwork and time delays eliminated, but the InTouch platform also allows for instant feedback. This means that producers can make informed decisions on maintaining and/or improving ration accuracy, consistency and presentation, thereby maximizing livestock performance. InTouch can also incorporate data from other herd management software programs and services such as the Dairy Herd Improvement Association, resulting in better quality analysis. 

Convenience is also a key feature of InTouch. Ration changes can be made from a computer or smartphone, through the InTouch customer service center or programmed directly to the KEENAN diet feeder. Nutritionists can also send ration changes directly to the weigh scale on the diet feeder.

The pre-self-loading order and mixing time takes the guesswork out of loading accuracy, suggesting a mixing order based on type, length of cut and moisture levels of the ingredients. It also calculates the required number of mixing revolutions needed to maximize effective fiber and delivers a consistent, uniform mix, based on 17 years of data gathered from farms all around the world.

To maximize profits for producers, InTouch’s support services help them monitor everything from feed costs and diet feeder performance to proper inclusion rate accuracy in order to maximize profits. Daily, monthly and annual performance reports for feed efficiency, the cost to produce 100 pounds of milk, profit margin per cow and production trends are automatically produced. This means no more combing through data or handwritten notes to find patterns that might unlock efficiency — using InTouch, farm consultants can generate benchmark summary reports that can reveal management practices to improve livestock performance and profitability.

The MechFiber difference

Based on years of data from more than 1 million cows, KEENAN has developed a range of products tailored to the needs of farmers, including reel, self-propelled, vertical and static machines for small- to medium-sized farms and pro-mixers for high-volume feed manufacturing and larger farms. These machines are designed to improve rumen health, resulting in improved feed efficiency and livestock production.

They are durable and easy to maintain, with a low daily operating cost and stationary blades for controlled chopping. They have a simple drive system, with no gearbox required and they empty completely, so no ration ingredients intended for one group of animals are fed to another.

Each diet feeder has two chambers (mixing and dispensing) and, together with a six-paddle reel and patented fixed-knives system, is engineered to produce a consistent, uniform, fluffy mix called MechFiber, which is unique to KEENAN machines.

Independent trials have consistently shown that MechFiber retains the fiber structure needed to stimulate rumination, allowing greater absorption of energy and maximizing feed conversion efficiency.

​

KEENAN diet feeders produce consistent rations from as little as five percent capacity up to 22,000 pounds. They easily handle and deliver a consistent, uniform mix for smaller dry cows, post-fresh cows and heifer groups. KEENAN customers can purchase separate ingredients to prepare their own premixes.  

Additionally, the low-power requirement design saves up to 50 percent in fuel consumption and reduces tractor and KEENAN diet feeder maintenance costs. Larger, more expensive tractors are not required compared to equivalent capacity vertical mixers, as a 120-horsepower tractor will operate a 1,000-cubic-foot diet feeder at recommended speeds of 1,200–1,500 revolutions per minute.

KEENAN started manufacturing quality diet feeders with cutting-edge designs and technology in 1978. In 2016, Alltech acquired KEENAN and is re-establishing the diet feeder in the U.S. market with a fresh approach to innovation that builds on KEENAN’s strong reputation for quality and performance.

Manufactured in Borris, County Carlow in Ireland, KEENAN products are available for purchase in the U.S. For more information about KEENAN, visit www.keenansystem.com.

[GREEN BAY, Wis.] – More than 220 dairy farmers, nutritionists and industry professionals gathered at Lambeau Field, home of the Green Bay Packers, on Nov. 30 to discuss preparing for the next generation of dairy farming. The theme of the event was “Traditions That Last: Finding Your Team’s Competitive Advantage.”

The day kicked off with a pre-conference breakfast, during which three dairy producers and one industry professional from the Midwest shared how they use technology within their operations:

• Zoey Brooks of Brooks Farms presented on the advantages of the operation’s automatic calf feeder barn. This automated system has resulted in healthier calves and provides opportunities for public education and a youth apprenticeship program. 
• Craig Fietzer of Fietzer Farms discussed the collar-mounted cow identification, rumination and activity tracking sensors used on his dairy. The data from these sensors is used to determine the best times to breed each cow, resulting in improved labor efficiency on the farm.
• Craig Finke of Finke Farm spoke on his farm’s automated feeding system, which delivers fresh feed six times a day. Feeding and milking automation systems allow him to spend more time with his cows in a herd management capacity.
• Jack Hippen, North American and European Sales Director of STgenetics, shared how sexing technology and genomic testing allow for production of higher-value products and services.

Dr. Bob James, owner of Down Home Heifer Solutions and professor emeritus in the dairy science department at Virginia Tech, opened the main conference, speaking on strategies to care for calves and heifers. He encouraged the audience to adopt new technologies that can improve calf care, calf health and labor management.

Dr. Roger Hagevoort of New Mexico State University’s Agriculture Science Center focused on how best to train the next generation of farm workers. He encouraged producers to work with third-party resources such as extension and industry organizations to provide the necessary training. Hagevoort stressed the importance of hands-on training and having managers spend time with their on-farm employees.

Robert Walker, CEO of KEENAN, closed out the morning session with a discussion on how technology is disrupting agriculture worldwide. Walker explained that agriculture is in the midst of a technological revolution that will disrupt current business models.

The afternoon continued with Dr. Roger Scaletti, who supports the Alltech^® Mineral Management team, addressing the crowd on mineral use in the diet to capture more profits. Scaletti provided research results indicating that the inclusion of organic trace minerals such as those in Bioplex^® and Sel-Plex^® improves milk production and the transfer of immunity from cow to calf as well as increasing heifer performance.

Carl Babler concluded the main conference with a market update. He shared his insights on the future of the dairy market in the Midwest, the United States and the world. According to Babler, the United States is positioned to be the animal protein provider of the world, and dairy products will play a factor in this position. There is a need for dairy producers who produce milk as a product and milk as a commodity, but it is important for operations to determine to which group they belong.

Larry McCarren, former Green Bay Packer and current host of “The Mike McCarthy Show,” then shared insight into past and current Packers team members, and how the team’s veteran players take it upon themselves to guide rookie players on how to be successful in Green Bay both on and off the field.  

Held each year in Green Bay, Wisconsin, the Alltech Wisconsin Dairy School is a long-standing tradition within the Wisconsin dairy industry. More than 2,700 dairy industry professionals have attended since it was first held in 2003. 

With the Veterinary Feed Directive (VFD) on the horizon and going into full effect Jan. 1, 2017, producers from all livestock sectors will be required to conform to these new regulations. For some, this will only require a little more paperwork; for others, a whole new business plan will be required.

A healthy start for calves begins with colostrum

With producers looking for ways to operate within the new law, the answer may be found in a fresh look at their management practices, beginning with calving. The first day of a calf’s life, especially the first few hours, is critical to its health and survival, setting the stage for lifetime performance.

The most crucial time is shortly after birth when the calf receives colostrum, which is naturally high in the nutrients necessary to increase the calf’s metabolism and stimulate the digestive system. Most importantly, it is the only source of immunoglobulins (IgG), or antibodies, which provide the passive immune protection essential for keeping the calf healthy.

Antibodies are absorbed in the gastrointestinal tract during the first 24 hours of life and provide the basis of the calf’s immune system for the first three to six months of age. Not only does colostrum provide the necessary antibodies needed for survival, but it provides a source of fats, proteins, vitamins and minerals.

Ensuring passive transfer of antibodies in colostrum feeding 

Colostrum feeding is the most important practice for getting the calf off to the right start. However, just because a calf receives the amount needed at the desired time does not guarantee the calf will remain healthy. A study by the United States Department of Agriculture (USDA) National Animal Health Monitoring System (NAHMS) showed that almost 20 percent of dairy calf heifers had failure of passive transfer, or a concentration of IgG in the serum less than 10 grams per liter (2007).

When the topic of colostrum quality comes up in conversation, one can hear “No, I do not test my colostrum, I can tell by physical appearance” or “I do not have issues with my calves, so the quality must be good.” However, there are many factors that affect colostrum quality that cannot be seen by observation only. It is recommended that a calf receive at least 100 grams of IgG, ideally 150 grams, from a minimum of 4 quarts of colostrum to help ensure passive transfer (USDA, NAHMS, 2007).

Factors affecting colostrum quality

What defines “good” quality colostrum? Research suggests that the concentration of IgG in the colostrum should be at least 50 grams per liter, with many factors affecting that level (USDA, NAHMS, 2007). There are other factors that contribute to and affect colostrum quality that are imperative to consider in your calves’ first feedings:

• Breed plays a big role in affecting the concentration level of IgG. Jerseys average 66 grams per liter of IgG compared to Holsteins at 48 grams per liter (BAMN, 2001). As a cow produces more colostrum, we tend to see dilution affecting the concentration level of IgG.

• Production of more than 18 pounds of colostrum at first milking (BAMN, 2001). Again, the tendency is to see a reduction in quality due to dilution of antibodies.

• The age of the cow. Typically, the younger the cow, the less quality colostrum she produces. Younger animals have not been exposed to pathogens as the older animals have. Therefore, the concentration of antibodies in the colostrum is much lower compared to older animals.

• The exposure a cow has to pathogens, whether young or old, varies from operation to operation. Each operation deals with its own issues when it comes to diseases. This is why a sound vaccination protocol needs to be in place not only to help promote animal health, but also to aide in producing good quality colostrum that has the needed antibodies for the calf to fight disease.

• The management of the cow during the dry period. A minimum of a three- to four-week dry period is needed to help ensure antibodies in the blood stream eventually concentrate in the colostrum.

• Along with length of dry period, nutrition can have an effect. If a dry cow is deficient in protein and energy, there will be a decrease in quality compared to cows with adequate nutrition.

• Cows that have colostrum removed by milking or leaking before calving will produce poor quality colostrum due to the removal of antibodies and the dilution of what colostrum is left.

• Colostrum that has a low concentration of bacterial contaminants (<100,000 cfu/ml total bacteria count, <10,000 cfu/ml coliform count) (Godden, 2008). To keep counts low, be sure proper handling of colostrum after milking is practiced to ensure a clean product.

• Seasons that impact the cow, causing cold stress or heat stress and affecting forage quality. Stress from environmental temperature not only has a direct effect on the cow, but also affects the quality of forages that are fed.

Tools for quality colostrum

To help ensure a good quality colostrum, it is beneficial to get into the habit of using either a colostrometer or Brix refractometer. The colostrometer measures specific gravity using a color coded scale that converts the measurement to determine the concentration of IgG. Lately, the use of a Brix refractometer has shown to be useful in testing colostrum. Normally used to measure the amount of sucrose in a solution, the Brix refractometer can use the values to determine IgG levels in colostrum.

There are many ways to help improve the quality of colostrum that is fed to newborn calves. Ensuring that colostrum quality is high improves calf mortality and morbidity rates and provides additional insurance when producers are faced with reduced use of antibiotics.

With temperatures exceeding 80⁰ Fahrenheit (F), cows can produce 4,500 to 6,000 British thermal units (BTU) per hour, an amount similar to the output of a 1,500-watt hair dryer. Heat can have serious manifestations in the dairy cow, resulting in effects such as (but not limited to):

• Lower production

• Rumen acidosis

• Milk fat depression  

• Poor reproduction

• Laminitis/lameness

• Weakened immune system

• Mastitis

• Transition disease (retained placenta, displaced abomasum, etc.)

• Lower body condition  score

It is only natural when cows are moved to a small space, such as the holding pen, that body temperatures rise. Research shows that a cow’s body temperature will increase by 3⁰ F in 20 minutes in a holding pen where there’s no cooling. By contrast, a cow’s body temperature will drop by 3.5⁰ F in that same 20 minutes when fans and a soaker system are used. Research by the University of Arizona showed that simply cooling cows in the holding pen increased milk production by 1.7 pounds per day in the summer.

There are can be adverse effects when developing a cooling system for holding pens if incorrectly applied. Water without fans will lead to increased humidity and heat stress in the holding pen, creating a “sauna” effect. Heat stress is a result of both temperature and humidity. The temperature-humidity index (THI) threshold for reproduction is 65,which is lower than the THI of 68 for milk production

Holding pen cooling tips:             

• Mount fans in rows, with airflow toward the back of the holding pen.
• Place 36-inch fans every 20 to 24 feet, or place 48-inch fans every 24 to 36 feet.
• Put 3 feet between fans (for example, between 36-inch fans mounted on 6-inch centers).
• Fan height should be a minimum of 8 feet, as low as possible but out of reach of cows and machinery.
• Mount fans higher if drop hose soakers like i-Wobs are used.
• For narrow holding pens (less than 24 feet) or pens with low ceilings, fans can be alongside the pen.
• Move air across and toward the back of the holding pen.
• Take advantage of prevailing winds.*

*Prevailing winds may be blocked by cattle, freestall dividers or headlocks. Wind speed is typically variable and is not dependable for adequate cooling of cattle.

Many in the U.S. Midwest have had the luxury of increasing their forage inventory over the last couple of years, and this year continues to be on pace.

Dairy cows have the ability to transform fibrous plant materials and byproducts into high-quality milk, but the rumen microbes require available protein to perform these fiber digestion functions. Protein prices in the last month have continued to rise, and many dairy producers are now looking at ways to reduce their out-of-pocket costs and feed more of their housed forage, which typically represents 50 to 70 percent of the total mixed ration.

The rumen bacteria need ammonia-nitrogen

In order to keep the rumen bacteria working more efficiently, an effective source of ammonia-nitrogen (NH3-N) is needed to enhance fiber-digesting bacteria. Research has shown that the bacteria in the rumen primarily use NH3-N in the ruminal fluid, which is derived from a non-protein nitrogen (NPN) source in the feed.

Possible nitrogen sources in the dairy ration

Feed-grade urea is a common form of NPN used in dairy rations, but because of rapid ammonia release, it leads to nitrogen inefficiency and wasted energy in the dairy cow. Vegetable protein sources, such as soybean meal and canola meal, can also be a source of slow-release nitrogen, but these ingredients can have variability in nutrient composition and take up valuable space in the ration. Many producers are trying to find ways to make the ration more energy dense, especially during periods of heat stress, and feeding less bulky ingredients may help to achieve this goal. 

Optigen^® is a unique protein alternative that is 256 percent equivalent crude protein from NPN and provides a sustained release of NH3-N in the rumen. This slow release allows for better synchronization with microbial protein needs while dramatically increasing nitrogen efficiency in the dairy cow. The key is to synchronize the ruminal carbohydrate and crude protein degradability in the rumen to increase microbial protein production and energy derived from rumen microbes. A combination of effective protein sources available in the rumen and post-ruminally — matching essential amino acids in the small intestine — has the potential to increase the cow’s efficiency. 

How does Optigen work?

Many rations can implement up to 6 ounces of Optigen and allow for some removal of protein from vegetable protein sources, such as soybean meal. For example, 6 ounces of Optigen provides 0.9 pounds of protein, which will replace 1.9 pounds of soybean meal, with space for 1.5 pounds of dry matter of corn silage. This will create space in the ration, which will allow the dairy producer to utilize more forage in the ration and to lower out-of-pocket costs.

In a recent trial done at the University of Wisconsin (Journal of Dairy Science 02, Suppl. 1, 290), 16 commercial dairy farms in Wisconsin incorporated Optigen into the ration and removed soybean meal. The space that it created was filled with corn or corn silage. The results show a 1-pound milk production response. You can find the full article on this research here.

Income over feed cost (IOFC) can be a critical metric when evaluating a farm’s profitability and the sustainability of a current or proposed feeding program. During times of low milk prices, understanding your costs can be crucial to a farm, effectively riding the wave to the next high or low in the milk price storm.

Understanding IOFC

IOFC is defined as the portion of income from milk sold that remains after paying for purchased and farm-raised feed used to produce the milk.  

Information you need to calculate IOFC:

1. Milk price average per month
2. Total milk produced per day over the period of a month
3. Number of cows as it relates to production during that month
4. Inputs (amount of feed used)
5. Cost per ton of feed input (to purchase or produce)

To illustrate with an example, we will use a 142-cow milking Holstein herd in Kentucky.

• Income
  • Milk price:  $15.50
  • Number of cows: 142
  • Average pounds produced per cow per day: 78 pounds
    • Income per cow per day: $15.50 * .78 = $12.09
• Feed costs:

IOFC = $12.09 (income) - $5.53 (feed costs) = $6.56 per cow per day

Feed to succeed

When evaluating your ration to maximize IOFC, there are potential changes that carry minimal to no cost but can have an impact on your bottom line.

1. Slow release non-protein nitrogen provides a concentrated source of ruminally-degradable protein. Due to the concentrated nature of the protein, a small amount provides the same nutrients as a larger amount of vegetable protein, allowing for reformulation potential to reduce feed costs. Optigen®, a product from Alltech, was utilized by Penn State in an example of IOFC calculation. You can read more here: http://www.dairyherd.com/news/industry/production-financials-cash-flow-mechanics.
2. Yeast: Feeding yeast has been widely researched and has shown to improve dry matter intake, stabilize rumen pH, maximize nutrient release and reduce overall feed costs.
3. Enzymes: Looking at the use of enzyme technology can be another avenue to maximize IOFC.  When feeding high-forage or high-corn diets, adding an enzyme that helps break down the key components in these diets, such as starch or plant fiber, can increase feed efficiency and improve milk production.

Using tools such as IOFC can lead to opportunities to gain a better understanding of your ration, to improve profitability of your herd and to understand your spending power when it comes to other on-farm purchases.  

As the distance between farmer and consumer closes around the world, we must continually adapt our methods to meet the ever-growing demand for high-quality, safe food. In the webinar, “The Path of Least Resistance,” we took a dive into the world of antibiotics, specifically how they have impacted and will continue to impact the agriculture industry. The key speaker, Dr. Richard Murphy, explained why we should worry about antibiotic resistance, where we are now with restrictions on antibiotics in livestock health and what opportunities exist for your operations.

Our three key takeaways were:

1. Worldwide, scientific evidence indicates an overall decline in the total stock of antibiotic effectiveness; resistance to all first-line and last-resort antibiotics is rising.
2. The livestock and poultry industries are not only facing increasing scrutiny from regulatory bodies such as the FDA and EFSA, but, worldwide, meat processors are starting to demand change.
3. Alternative growth promotion strategies are available that utilize strategic nutritional management practices as part of an antibiotic-free strategy for animal production.
