Dr. Cannas presented a Real Science Lecture webinar on October 17, 2023, titled “Diets of Productive Sheep & Goats: Performance & Health.” You can find the webinar recording at balchem.com/realscience.   Dr. Cannas outlines the topics he covered in his webinar, including nutritional requirement differences between small and large ruminants, particularly in late gestation. Small ruminants have a shorter gestation and are more prolific than cattle, for example, and this means they have more nutritional challenges in late gestation. Dr. Cannas covered supplementation, basal diet ..read more

Dr. Zimmerman presented a Real Science Lecture webinar on December 12th, 2023, titled “Not All Rumen-Protected Products Are Created Equal.” You can find the webinar recording at balchem.com/realscience.   Clay outlines four attributes of a good rumen-encapsulated product. They are feed and TMR stable, ruminal stable, nutrient bioavailability, and good efficacy biologically in the animal.  (6:21) Kari describes a TMR stability test that Balchem has been perfecting based on a paper published in 2016. One to two grams of a rumen-protected product (based on the nutrient composition ..read more

This episode comes to you from the “New Developments in Transition Cow Nutrition” seminar in Stoke-on-Trent, England. Dr. Santos, Dr. Reynolds and Dr. Zimmerman spoke at the seminar. Each speaker gives a brief overview of their seminar presentation, and then the panel takes questions from the audience. In his presentation, Dr. Santos discussed some of the latest research using rumen-protected choline in transition cows. There is substantial evidence that choline plays an important role in transition cow nutrition, particularly because of its consistent positive effect on the yield of energy-co ..read more

Dr. Harvatine gave a presentation on the Real Science Lecture series on April 2nd titled “High Oleic Soybeans, Where Do They Fit Into Dairy Diets?” Access the recording at balchem.com/real science. As Dr. Harvatine thinks back over his 15 years at Penn State, he didn’t think he’d do much fat supplement work. But we keep getting new questions, new products, and new challenges. One of these is high oleic soybeans, which could be an opportunity to grow some of our own fat on the farm. (6:35) High oleic soybeans have been around for about seven years or a little longer. They were developed for fry ..read more

This journal club episode comes to you from the 2024 Tri-State Dairy Nutrition Conference. The paper is “Assessing Transition Cow Health: Integrating Traditional and Novel Biomarkers” from the conference proceedings with Dr. Andres Contreras of Michigan State University. What is a biomarker, and what makes a good biomarker? Dr. Contreras defines anything that can help assess a physiological response or pathological state. Two examples would be BHBA (beta-hydroxybutyrate) and NEFA (non-esterified fatty acids), both fat mobilization measures. (2:56) Dr. Contreras structured the paper in three se ..read more

This journal club episode comes to you from the 2024 Tri-State Dairy Nutrition Conference. The paper is “Major Accomplishments in Calf Nutrition and Growth” from the conference proceedings. Accelerated milk feeding of calves results in about a thousand-pound first lactation production increase. The mechanism is unclear: it could be isolated to the mammary gland or related to the functional ability of the digestive tract and liver to support lactation. Economic analyses have shown an advantage of $205 per calf. (6:04) Regarding amino acid requirements of dairy calves, whey-based milk replacers ..read more

This journal club episode comes to you from the 2024 Tri-State Dairy Nutrition Conference. The paper is “Practical Aspects of Reducing Carbon Footprint by Dairy Farms Through Feeding” from the conference proceedings. In the U.S., livestock competes with oil and gas for the top source of methane emissions. While “carbon-neutral” agriculture may be easy for modelers to show, Dr. Hristov feels this is misleading and probably impossible in practical dairy farming. However, mitigation can be addressed in several directions, and nutrition can have perhaps the largest impact. Management practices, ge ..read more

This journal club episode comes to you from the 2024 Tri-State Dairy Nutrition Conference. The paper is “Methane in the context of circular dairy farming” from the conference proceedings. What is circular dairy farming? The concept is that instead of extracting or using natural resources and then discarding the wastes in a linear kind of fashion, economies should try to be increasingly circular. This would include the concepts of reusing, recycling, upgrading, upcycling, etc. Traditionally, the focus on methane was about the inefficiency and leakage of energy and finding a way to minimize that ..read more

This episode comes to you from the 2024 Tri-State Dairy Nutrition Conference, where Balchem sponsored a Real Science symposium titled “New Discussions in Amino Acid Nutrition.” Each of our guests presented at the symposium, and their presentations can be found at balchem.com/realsciencemedia Dr. Van Amburgh presented “Amino Acid Nutrition for Maximizing Milk Component Yield.” When considering nitrogen efficiency, we generally compare intake nitrogen, which includes non-protein nitrogen, against milk nitrogen. In high producing cows, aggregate amino acid values are running about 70 to 73% effic ..read more

While Dr. Jardon only had milk in his glass for this pubcast, he did share about his bottle of “wheyskey” (whiskey made from whey) from Wheyward Spirit Distillery in California (https://www.wheywardspirit.com/). Iowa State Dairy Extension is offering a webinar, “Fermentation and Distillation of Whey to Produce Spirits at Copper Crow,” on May 15 at noon Central. Curtis Basina of Copper Crow Distillery in Bayfield, WI, will be the speaker. You can sign up for the webinar at https://go.iastate.edu/WHEY (4:13) Dr. Dhuyvetter presented a March 5 webinar on dairy economics, which can be found at bal ..read more
