What a cow needs from her diet
This module is part of the DairyNZ FeedRight program. It is also for anyone interested in understanding what a cow needs from her diet.
In this module, we look closely at the key nutrients a cow needs for production and reproduction, and why she needs each one. By the end of this module, you'll be able to:
- Explain why a cow needs protein, energy, water, fibre, vitamins and minerals in her diet.
- Recall the main factors that affect a cow's requirements for each of the components.
The module should take 15-20 minutes to complete.
