For many dairy nutritionists and farmers, the next step to higher milk protein content is balancing amino acid levels in the herd’s rations.
When the ration’s amino acid levels are matched to the cow’s biological needs, the cow’s nutritional status improves. To achieve this goal, the ration fed typically includes a rumen-protected, metabolizable methionine. The most common result is an increase in milk protein, the best known benefit of amino acid balancing, according to Dan Luchini, Ph.D., Manager – Ruminant Products Technical Services at Adisseo.
Other benefits exist, though, he notes, such as increases in both milk volume and milk fat and a decrease in nitrogen excretion. To quantify the response to amino acid balancing in a single number, the figure for energy corrected milk (ECM) is often used.
Balancing amino acids supports more efficient nitrogen so less crude protein (CP) can be fed. Reducing crude protein helps reduce feed costs and makes room for more high-quality forage while decreasing nitrogen excretion.
In recent research, one group of cows was fed a 16.8% crude protein diet that provided an estimated 2,590 grams of metabolizable protein with a lysine to methionine ratio (Lys: Met) of 3.33. Another group of cows was fed a 15.7% crude protein diet that delivered 2,450 grams of metabolizable protein for a Lys: Met ratio of 2.98. The ration with higher crude protein contained 140 more grams of metabolizable protein, yet its amino acid levels were out of balance. Both rations delivered similar grams of metabolizable lysine. The ration with lower crude protein, however, provided six extra grams of metabolizable methionine from its 40 grams of dry MetaSmart, a rumen-protected methionine.
The cows fed the diet with the lower nitrogen load (15.7% CP) produced two extra pounds of milk with better fat and protein percent. They had a significant 3.5 lbs of extra ECM. They also had lower plasma urea nitrogen (PUN) and milk urea nitrogen (MUN) which confirm better efficiency of nitrogen utilization.

Earlier this year, Novus International kicked off a brand new program for dairy producers called C.O.W.S. – an acronym for Comfort, Oxidative Balance, Well-Being and Sustainability.
At World Dairy Expo, I caught up with Robin Rastini at the Novus exhibit to get an update on how that program is going. “So far we’ve done about 30 additional assessments on top of the initial benchmark, some of those are re-assessments off of the initial benchmarks,” she said. “We’ve seen huge improvements on those that have gotten re-assessed.”
In one case, Robin says a producer switched to Jersey cows because his stalls were too big for the breed he was using and instead of changing the barn, he changed the breed. “In other cases, it was as simple as taking out some brisket boards or changing the neck rail placement or bedding material. It’s definitely had an impact on improving cow comfort and lameness,” she said.
Robin also talked about Novus’ new BioOptimizedSM Trace Minerals Program. “That encompasses our MINTREX® minerals as well as our MAAC® line,” she explained. “These chelated trace minerals really perform better than many of the other classes of minerals.” The new program was just introduced last month so World Dairy Expo was the first opportunity for Novus to unveil it to producers.

The oxidative balance of a dairy cow is one of the many factors that can limit milk production and a producer’s bottom line. That’s why Novus International places a lot of emphasis on helping dairy producers control or eliminate oxidative stress in their animals.
Diet plays a key role in oxidative balance since vitamin and mineral imbalances can be linked to oxidative stress. There is a natural balance between free-radical formation and the defense system and for a dairy cow to stay healthy, the systems should stay in balance. But when the body is under stress, free radicals can get out of balance. When this system is out of balance, the body initiates an oxidative chain reaction, resulting in oxidative stress. The nutrition program can benefit from the proper balance of antioxidants, minerals and amino acids.
At World Dairy Expo, I sat down with Dr. Dennis Nuzback, Technical Services Manager for Novus, and got a lesson in oxidative balance. “Novus’ oxidative balance program is basically designed around three products,” Dennis explains. “First is the anti-oxidant package called Agrado-Plus, and the minute that gets mixed with the TMR that product can begin to scavenge free radicals in the diet, decreasing the free radical load to the cow.”
Next is an amino acid product like Alimet or MFP, “that has both a ruminal effect and a metobolizable or bypass methionine effect.” The methionine can be converted into the amino acid cysteine, which is used extensively by the immune system. Finally, trace mineral supplements such as Mintrex and Zorien SeY provide key components of antioxidant enzymes.
It’s all pretty technical stuff, but a dairy producer doesn’t need a degree in chemistry or biology to understand the bottom line. “Through a variety of field trials we try to present the results of our products in something the dairyman can understand,” he said. “If for a 15 cent investment in those different products, you can get three more pounds of milk, which hit 16 bucks in Iowa last month – 48 cents for a 15 cent investment, that’s a very reasonable return on investment.”

At World Dairy Expo this year, Arm & Hammer Animal Nutrition was talking with producers about income over feed costs and how they can improve that number.
“Income over feed costs is a very simple measure,” explains Senior Manager, Technology, Arm & Hammer Animal Nutrition, Dr. Elliot Block. “It’s how much money you’ve made for your milk, total revenue, minus what the feed cost was to make that milk.”
Increasing the amount of income for milk might be best accomplished by raising the components, such as milk fat, by adding a few cents to the diet. “Today, where milk fat is almost equal to milk protein in price, which we’ve never seen before, you get a .1 change in milk fat without changing volume, that’s a fairly large increase in income per hundredweight of milk.”
One way for dairy producers to boost milk fat production by increasing dietary cation-anion difference (DCAD) with a high-quality potassium source. To learn more about balancing diets for optimal DCAD levels, Arm & Hammer has developed a new DCAD calculator, which can help determine ration DCAD and provide guidelines for appropriate DCAD levels based on stage of lactation. The DCAD calculator is available at www.AHDairy.com.

Less crude protein in the diet of dairy cattle can actually improve nitrogen efficiency and ultimately result in both economic and environmental benefits.
That was the message at a seminar sponsored by Novus International today at the Sheraton next to World Dairy Expo. Dr. Larry Chase with Cornell University presented some compelling findings that indicate the traditional 18% crude protein dairy diet could be lowered with very positive results.
“At the tissue level, what you really need are amino acids as the building blocks for maintenance, growth, lactation, reproduction,” said Dr. Chase. “So we really need amino acids, not protein per se.” His work shows that there is a point where more crude protein in the diet is literally wasted in the animal, resulting in more manure and urine output, not more milk output – and protein is expensive. “We don’t want to spend a lot of money to make better quality manure,” he said.
Dr. Chase believes that producers could ultimately reduce CP in their rations by two percent or more with no drop in milk production. “Practically, I think a lot of herds can get down towards 16 percent or slightly under,” he says. It does mean that produces need to strike a delicate balance in their rations, stressing metabolizable protein rather than crude protein with amino acids and energy sources, but the payoff can be significant. “What we found in field trials is if we reduce the protein being fed in excess of requirement, we save the farmer money and lower excretion in the environment without hurting milk production.”
When Dr. Bob Stoltzfus with Lancaster Veterinary Associates in Lancaster, Pennsylvania heard about Dr. Chase’s research a few years ago, he was intrigued enough to try it himself on a real operation, resulting in what he calls a “transformation” from a conventional diet to a lower CP diet. “I went from an 18.3% crude protein diet in 2007 to a 16.2% crude protein diet in 2010,” he said. “Production was not affected by it, components were not affected by it, there are changes in the diet that you do, but the bottom line is that you excrete less nitrogen into the environment and in a 200 cow herd we made them about $22,000 per year.”
The financial incentive should be enough for producers to at least give it a try now, before they are forced to by environmental regulations. “Certainly in my area, in the Chesapeake Bay watershed, it’s going to be mandated and probably enforced by the EPA in the very near future, that farms have feed management plans which involve the inputs into the cows that ultimately result in waste in the manure in the form of nitrogen and phosphorus,” he said.
He recommends that producers who are interested in trying a lower crude protein diet work with their nutritionist to find the right balance in the diet to make it work.

There have been some concerns lately in the dairy industry about low milk fat levels, something that has left many dairy nutritionists scratching their heads.
Dr. Scott Bascom, a nutritionist with Cooperative Plus in Wisconsin, says 2009 was one of the worst years he has seen for milk fat tests, which had a significant financial impact on some of his clients on top of the already poor price situation. “It was very frustrating. I have a PhD so I’m supposed to have all the answers,” Scott told me during an interview at World Dairy Expo in the Arm & Hammer Animal Nutrition booth. The animals appeared healthy with no signs of acidosis and he had no luck finding issues with starch or oils in the diet. Then he started looking at the DCAD (dietary cation-anion difference) balance and struck pay dirt when he started adjusting the diet using DCAD Plus.
“The results we saw were pretty impressive,” said Scott, who brought the actual results to show people because they’re so amazing. “In one farm, in mid-May to early June, we were struggling to get to a 3.5 fat test, with lows of 3.39. It was about the fifth of June when we put a new diet in place balanced for DCAD. Between the 5th and the 19th, we averaged 3.68 in this herd with some days a little bit over 3.7.” That resulted in 40 cents more per hundredweight of milk. Another herd had similar results and Scott says he had happy clients. “With the quick response we saw to the DCAD Plus, it was almost an immediate increase in their milk check, just from the added fat.”
Scott says his experience with Arm & Hammer has been a positive one, ever since he was a little kid on the farm and his grandfather was feeding sodium bicarb. “Not only is it the value of the products at Arm & Hammer, it’s the value of the people and their concern and compassion for the dairy industry,” he said.
A&H developed a new web-based DCAD calculator to help producers more effectively balance their rations. More information can be found on the home page for AH Dairy.
Dr. Juan Tricarico brought the history of yeast research to the audience at the Dairy Solutions Symposium. He is Research Manager for Ruminant Nutrition for Alltech. He says there is a lot of information about yeast and its mode of action. He hopes that participants in the symposium will leave with a better understanding of how yeast affects rumen function and improves the ruminal environment as a whole so that it can be used more effectively. This will give the dairy farmer a bigger bang for their buck when they invest in yeast products.
“Modifying the rumen to reduce the risk of acidosis” was the title of Prof. Sergio Calsamiglia’s presentation at the Dairy Solutions Symposium. He works in the veterinary school at Universitat AutÒnoma de Barcelona.
He says research shows that acidosis is not just a pH problem but related to the type of feed you’re using. There is evidence that although using bicarbonate helps, it doesn’t solve the problem. Conversely, there are feed additives that don’t impact pH but help the problem. He says he thinks the term acidosis may mislead people since there are products like yeast that can help the problem even though it is not a buffer. The bottom line is that good nutrition and animal care is the most important thing to work on.
We’re leaving beef month behind to enter into dairy month. Midwest Dairy Association invites you to celebrate and learn how dairy can make sense for you. Check out their blog.
June Dairy Month started out as a promotion to help distribute extra milk when cows started on pasture in the warm summer months. Today, its rich history continues, with communities, companies and people from all over the country observing June Dairy Month in a variety of ways. In the Midwest, dairy farms and families often open their gates to visitors at breakfasts and tours, while stores and other business feature dairy products. We’re excited to share facts and information about June Dairy Month, ones we hope you can use for your own recognition of the observance.
Products from the acquisition will align with Novus’s MINTREX® chelated trace mineral products and further expand its mineral technology. When complete, this acquisition will enable Novus to offer its customers and the animal agriculture market an expanded chelated trace mineral product portfolio to support their livestock operations.

A new study recently released by Nutrition Today suggests that the prevalence of lactose intolerance may be far lower than previously estimated.
The study, which uses data from a national sample of three ethnic groups, reveals that the overall prevalence rate of self-reported lactose intolerance is 12 percent – with 7.72 percent of European Americans, 10.05 percent of Hispanic Americans and 19.5 percent of African Americans who consider themselves lactose intolerant.
These new findings indicate that previous estimates of lactose intolerance incidence – based on the incidence of lactose maldigestion – may be overestimated by wide margins. Previous studies have found lactose maldigestion, or low lactase activity in the gut, to occur in approximately 15 percent of European Americans, 50 percent of Mexican Americans and 80 percent of African Americans.(2,3,4) The new study shows that lactose intolerance, based on self-reported data, may actually occur far less frequently than presumed.
“There’s so much confusion surrounding lactose intolerance,” said Theresa Nicklas, DrPH, of the USDA/ARS Children’s Nutrition Research Center at Baylor College of Medicine and lead study author. “By getting a better handle on the true number of people who deal with this condition every day, the nutrition community can be better equipped to educate and provide dietary guidance for Americans, including strategies to help meet dairy food recommendations for those who self-report lactose intolerance.”

This is positive news for school kids and dairy producers alike. Reuters recently published an article about the praise International Dairy Foods Association has been giving President Obama and USDA Secretary Vilsack for their push for more dairy products in school lunch and breakfast programs. Kudos to these government officials for understanding the importance of dairy in growing children! Here is an excerpt from that article…
“Kids are eating far too few low fat dairy products,” said Vilsack. This is particularly important because the U.S. Department of Agriculture’s school meal programs are often the only source of dairy products in many children’s
diet.”
USDA data shows that per capita milk consumption has been falling for decades, and that this decline corresponds to the dramatic increase in per capita consumption of competing beverages among school children. The USDA also reports that the vast majority of children do not get the recommended amount of calcium. Only 5 percent of girls and 25 percent of boys aged 9 to 13 get the calcium they need.
To tell dairy farmers attending the Global Dairy 500 Conference what to “leave in and what to take out” was Mike Hutjens, University of Illinois. Mike is very passionate about the diary business and so enthusiastic that our translators had to get him to slow down so they could translate for our international audience.
Hutjens addressed feed questions and says he boiled the answers down to a few main points or suggestions. To start with he suggests looking at forages and forage quality. Then he suggests maintaining milk production and not giving up milk production. He says to look at feed additives since many are very cheap right now. He says the price of milk may come back short term and it’s important to have the right team on the field using a football analogy. When it comes to nutrition he says that when you go with the premise that you can’t give up milk, then you have to look at substitute feed choices that may be more economical.
When it comes to questions from the attendees here he says he gets asked a lot about new corn varieties and chopping the silage and how long to store it. He says producers are asking how to make things work more efficiently for them where they are. Looking ahead he still sees some tough times but with some bright spots like reasonable feed costs.
World Dairy Diary coverage of World Dairy Expo is sponsored by:
Novus International treated some of the top dairy nutrition consultants from the upper Midwest to lunch and a seminar today at the Sheraton next to the World Dairy Expo. One of the presenters was Dr. Tom Overton of Cornell University who talked about the biology behind a couple different ration software programs for dairy nutrition modeling.
“The dairy nutrition modeling effort has been going now at Cornell for more than 30 years and that has led to the development of these programs,” Tom says. “Cornell Penn Miner (CPM Dairy) is a partnership of Cornell with the University of Pennsylvania, Miner Institute, and then a sister program, the Cornell Net Carbohydrate and Protein System (CNCPS).”
Tom says both programs are the result of an on-going effort to “better define the biology of cows and how we might be able to put diets together in order to make them more productive and efficient and help our producers be more profitable.”

The National Dairy Council (NDC) is excited to announce the launch of its new blog, “The Dairy Report: News, analysis and opinion on nutrition and health research.” This new blog offers expertise, opinions and dialogue related to current trends and events in dairy foods, nutrition and science.
A new post on The Dairy Report highlights a study that provides further evidence that milk consumption, including flavored milk, is not associated with body fatness in children and adolescents. The study, published in the American Journal of Clinical Nutrition, found that only sweetened beverage intake (such as sweetened fruit flavored drinks or sodas) at five years of age, but not milk, flavored milk or 100 percent fruit juice, was a significant predictor of girls’ body fatness from 5 years to 15 years.
Readers are encouraged to add The Dairy Report to their RSS feeds, join the e-mail distribution list, share feedback, express opinions regarding posts, and call attention to upcoming research or topics of interest.

Another interesting article by Charlotte Johnston with TheCattleSite. Titled, “Practical Aspects of Feeding Grass to Dairy Cows,” this article details the use of grass based systems in a low cost feeding method for dairy producers. Check it out below…
Research that has been carried out by Teagasc at Moorepark Farm, Ireland have shown that fresh grass is one of most productive and viable feeds. Complete grass systems are operated in New Zealand and Australia – should other countries be adapting these grass management techniques to increase milk yields. From the 43rd University of Nottingham Feed Conference, TheCattleSite junior editor Charlotte Johnston.
Why use a grass based system?
Grass based systems are known to:
-Lower the cost per unit of milk production
-Have superior milk composition, such as greater fatty acids
-Have more sustainability with regard to economic, social and environmental effects
-Compared to other feed options, Pat Dillon, head of Moorepark Dairy Production Research Centre believes that good grassland management is not only the most viable but also the most productive. The table below shows the relative cost of grass compared to silage and concentrates. As can be seen from the research, feeding concentrates is 3.5 times more costly than applying good grass management.
This week, Agriculture Secretary Tom Vilsack met with NFL Commissioner Roger Goodell and Thomas Gallagher, chief executive of Dairy Management, Inc., which runs the National Dairy Research and Promotion Program. The NFL and DMI are launching Fuel Up to Play 60, an innovative nutrition and fitness program based on the Dietary Guidelines for Americans, in some 60,000 schools this fall. The social marketing program empowers students to assume leadership in being more active and eating more healthy foods.
“National Dairy Council is honored to work together with USDA and the NFL on Fuel Up to Play 60,” said Gallagher. “Child nutrition, particularly in schools, has been a cornerstone of National Dairy Council for nearly a century. This program centers on youth taking the lead in changing the school environment through increasing opportunities for eating healthier and getting more physical activity.”
The campaign will inspire kids to “fuel up” with the nutrient-rich foods they often lack—fruits, vegetables, whole grains, and low- or no-fat dairy products—and “get up and play” with 60 minutes of daily physical activity. Student teams will evaluate their school’s “wellness” and choose the healthy eating and physical activity programs on which the school will focus.
The first presenter this morning at the Novus International Media Day was Stephanie Gable, Marketing Manager, Ruminants. Stephanie gave us the lowdown on how Novus is helping dairy producers achieve “oxidative balance” in their herd. They’ve found that just like with human beings, when dairy cows come under stress from oxidation they become less productive. So to prevent it and maintain a healthy balance they recommend the use of antioxidants like AGRADO Plus feed ingredient.
They feel so strongly about the importance of dairy nutrition that they’ve created a new website on the subject where you can learn a lot more about this oxidative balance issue.
You can listen to my interview with Stephanie here:
