Before we start thinking about formulating the most precise diet for our cows, we have to make sure that the feed is properly prepared and delivered to cows. In order to do that the right way, we have to understand the feeding behavior of cows. In this episode, Dr. Trevor DeVries discusses what drives cows to feel hungry, what the feeding frequency is, how we can identify the individual behavior of the animals at the feed bunk, the benefits of automatic systems, and the challenges of research on nutrition with automated milking systems.

“We don't want a cow to eat because they’ve been out of feed for so long that they’re hungry and need to do it right now – we want cows to be internally hungry.’’ – Dr. Trevor DeVries ‬
