Calf Rearing

Grow better calves with AgriVantage

Calf rearing is an investment in the future that starts with selecting a good calf milk replacer

Nutrition in the first 8 weeks, growth in the milk feeding phase, is what determines development of the udder cells which in turn are responsible for milk production.

After these 8 weeks, we can no longer activate the cells and other physical characteristics which influence future milk production. This is a once in a lifetime opportunity to grow better calves.
