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.
