Calves & Heifers

Raising dairy heifers off-site increases the possibility of disease introduction, especially if animals are reared in a facility where they commingle with cattle from other dairies.

When discussing calf barn ventilation, invariably the topic of using four air exchanges per hour for cold-weather ventilation will come up. After all, we wouldn’t want “too much” of that cold air in the barn. Or would we?

Protecting the investment in your heifer herd has never been more important. We tend to put a lot of emphasis on genetic progress with our breeding programs, but we fail to partner that with a quality heifer management program to allow our heifers to express their full genetic potential.

While bovine viral diarrhea virus (BVDV) persistently infected (PI) calves may look normal on the outside, they are comparable to a Trojan horse in your dairy herd. This is due to the level of virus each calf continues to shed throughout their lifetime.

“We have way too many calves with acidosis.”

“Rumen pHs are low, must be acidosis.”

“I need to switch calf starters; this one is causing acidosis.”

Have any of these thoughts crossed your mind? If so, you’re not alone. But, you might be missing the real question – do your calves actually have acidosis?

Winter always seems to sneak up on us before we know it. The amount of daylight gets shorter and shorter and the temperature gets colder and colder. We have a million things on our mind and prepping the calf facility might have fallen to the bottom of the to-do list.
