Dr. Andre Pereira: Amino acids in Dairy Nutrition | Ep. 03

Thu, 09 Nov 2023 16:00:00 +0000

Today, I hosted Dr. Andre Pereira in a riveting discussion on the critical role of essential amino acids in the diets of dairy cows. We talked about extensive research on methionine, viewing it not just as an additive but as a fundamental nutrient, and its impact on cows from pre-fresh to fresh stages. Dr. Pereira also explored the precision required in balancing amino acids like lysine and the emerging significance of branched-chain amino acids in dairy nutrition. Discover the strategies behind successful diet formulations that leverage the energy-methionine relationship, pioneered by Cornell's research.

Dr. Luiz Ferraretto: Dairy Cattle Nutrition Puzzle | Ep. 02

Wed, 01 Nov 2023 19:55:00 +0000

Ruminants exhibit intricate feeding behaviors that can significantly impact their overall health and production. A pivotal factor affecting their feeding behavior is the quality of forage and associated feed management techniques. Increasingly, experts believe that the particle size of forages can influence the duration cows spend at the feed bunk and, consequently, their food consumption. In this episode, I welcomed Dr. Luiz Ferraretto, Assistant Professor and Ruminant Nutrition Extension Specialist at the University of Wisconsin-Madison, for the second time. We delved into the debate on the particle size of forages and its notable effect on the duration cows linger at the feed bunk. Additionally, this episode highlights the impact of varying forage sources on shaping a cow's diet and, ultimately, its feeding patterns.

Dr. Luiz Ferraretto: Forage Impact on Dairy Behavior | Ep. 01

Thu, 26 Oct 2023 17:03:34 +0000

Welcome to The Dairy Nutrition Blackbelt! I am Bill Weiss, and this marks our inaugural episode. Please make yourself comfortable. Today, I had the privilege of hosting Dr. Luiz Ferraretto, an Assistant Professor and Ruminant Nutrition Extension Specialist at the University of Wisconsin-Madison. Our conversation centered on feeding behavior — a critical determinant of an animal's overall productivity and well-being. In our discussion, we explored the relationship between forage quality and feeding behavior, variations in resting and rumination periods relative to feed consumption, and the distinct behaviors elicited by corn silage versus sorghum silage.
