CALVES & HEIFERS

Dairy producers are working to raise both the optimal number and the highest-quality heifers for their operations.

Nutrition is important at all stages of life for the dairy cow, but it is critical for young calves as they grow and mature.

It’s hot enough these days to fry an egg on the hood of a tractor. Heat stress is a major issue, even in Canada. Yet not much is said about the negative effects of heat stress in calves.
