Guests: Dr. Billy Brown, Kansas State University; Dr. Heather White, University of Wisconsin-Madison; Kelli Brost, University of Illinois; Dr. Jim Drackley, University of Illinois; Dr. Sergio Martinez Monteagudo, New Mexico State University; Jair Parales Giron, Michigan State University; Tess Stahl, University of New Hampshire; Dr. Pete Erickson, University of New Hampshire; Dr. Vinicius Machado, Texas Tech University
Today’s podcast is the second podcast filmed at the American Dairy Science Association Annual Meeting in Ottawa, Ontario, Canada. Joining us are researchers with abstracts of interest chosen by the Balchem technical team.
Our first guests are Dr. Billy Brown, Kansas State University, and Dr. Heather White, University of Wisconsin-Madison. Dr. Brown said results from feeding choline in utero showed no differences in the weight of the animal or ribeye areas, but they did have greater marbling, which is exciting. (4:19)
Dr. Brown’s poster title is: Effect of in utero choline exposure on Angus × Holstein carcass characteristics
Our second guest is Dr. Sergio Martinez Monteagudo from New Mexico State University. Dr. Martinez Monteagudo mentioned that while upcycling is not new and is used in other industries, it is more difficult to do in the food industry. Dr. Martinez Monteagudo turned lactose into something more used, sweeteners.
Dr. Martinez Monteagudo’s presentation title: Upcycling strategies of dairy byproducts and waste for value-added applications.
Next up is Kelli Brost and Dr. Jim Drackley, both from the University of Illinois. Kelli found in her research that there is an effect on cow’s milk protein and fat percentages when looking at summer versus non-summer seasons. When you look at winter versus non-winter or winter versus summer, she saw the exact opposite. (27:50)
Kelli’s Poster title is: Relationships between birth and calving season on first lactation performance of Holstein dairy cows in the Midwestern USA
Now, we’re hearing from Jair Parales Giron from Michigan State University. Jair’s research showed that fat has different effects from a low or high-starch diet. He also recommended that if you can’t have a high-energy or low-starch diet, fatty-acid supplementation could work.
Jair’s presentation title is: Fatty acid supplementation interacts with starch content to alter production responses during the immediate postpartum in dairy cows
Joining us next are Tess Stahl and Dr. Pete Erickson from the University of New Hampshire. Tess studied the effects of a DCAD diet on Jersey cows. she found that minus 40 cals without and with nicotinic acid or niacin were equally feed efficient. And then there was a decrease with the minus 80. So she assumes that minus 80 is too harsh of a DCAD. (54:24)
Tess’ poster title is: Evaluation of colostrum quantity, quality, and bioactive compounds from Jersey cows fed two concentrations of dietary cation-anion difference with or without nicotinic acid and its effect on calf performance
Lastly, we have Dr. Vinicius Machado from Texas Tech University. Dr. Vinicius didn’t have any solid conclusions in his research but did notice that raising beef-on-dairy calves takes a different focus and approach than dairy cows or traditional beef cows. Throughout his portion, he hypothesizes what some options are. (1:38)
Dr. Vinicius Machado’s presentation title is: Management of beef-on-dairy calves: Should we raise them differently?
