The first priority in grouping milk cows should be the 2-year-olds,” Weiss said in reinforcing his message. There are five key reasons to separating this group. Once separated, these young cows will:1. Lie down more often.
2. Eat more feed.
3. Eat more frequent meals, improving rumen health.
4. Be exposed to fewer aggressive interactions.
5. And because of the previous four reasons, these 2-year-old cows will give more milk.
“There are other grouping strategies, including separating fresh cows or late-lactation cows,” said The Ohio State University nutritionist. “However, the first priority should be separating 2-year-olds.”
“Overall, I recommend dairy farmers put their energy in two, or at most three, production groups,” concluded Weiss.
