This episode of the Real Science Exchange podcast was recorded during a webinar from Balchem’s Real Science Lecture Series. Dr. Goff sees three main challenges for transition cows: negative energy and protein balance, immune suppression, and hypocalcemia. About half of all older cows experience hypocalcemia, and around 3% will experience milk fever. Cows develop hypocalcemia if they are unable to...

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...

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 respon...

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...

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 i...

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. T...

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 nitr...

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 Disti...

Dr. Penner describes two primary factors of gut health to be absorption and barrier function or permeability. His lab’s work on permeability is suggesting that intestinal regions really drive total gut permeability to a much greater extent than ruminal permeability in dairy cows. (7:06) Ms. Bertens is Dr. Penner’s Ph. D. student and explains some new methodologies she developed for measuring gut p...

Guests: Dr. Bill Weiss, The Ohio State University; Dr. Marcia Endres, University of Minnesota Dr. Endres begins with a description of a dataset she collected containing individual body weights from 34 robotic milking herds. Weights were collected for every cow; every time that she came into the robotic milking station. Dr. Endres’ team was interested in the relationship between the amount of body...

Dr. Räisänen completed this research during her Ph. D. at Penn State. The meta-analysis included 17 different studies published between 1999 and 2022 investigating supplemental histidine for lactating dairy cows. They divided the type of supplemental histidine between infused histidine and rumen-protected histidine and the basal diets between corn silage-based and grass silage-based. (4:34) Primar...

Dr. Hristov started working with canola meal after he commissioned a review paper comparing canola and soybean meal when he was editor of the Canadian Journal of Animal Science. In that review, most of the studies used solvent-extracted soybean meal. Because canola has a higher oil content, it is always mechanically extruded to remove oil before solvent extraction. This paper is a more fair compar...

Dr. Godden opens this episode with a 30,000-foot view of colostrum management. Colostrum management has been a hot topic for decades, and herds still have opportunities to improve. Researchers continue to learn how to advance colostrum management. The basics include the three Qs: quality, quantity, and quickness. Other critical factors are cleanliness and feeding clean colostrum. Dr. Godden also b...

Kirby begins with a description of the mechanism of amylase-enhanced corn. The amylase is located in the kernel and, once activated by temperature change, works to increase the digestibility of the starch. A small amount of activation is thought to occur during silage fermentation, with further activation once it reaches the rumen. This paper evaluated digestibility and milk production in cows fed...

Guests: Dr. Paul Fricke and PhD Candidate Megan Lauber, the University of Wisconsin-Madison Dr. Fricke starts this episode by describing the long-term negative trend for reproductive performance in dairy cows that took place from the mid-1950s to around 2000.  The reversal of this trend is due to the use of genomics to select for fertility and the use of synchronization and fertility programs in d...
