Final answer:
Calves are usually weaned from the cow at around 6 to 8 months of age at the DRU. The weaning process involves gradually introducing solid food and transitioning away from milk. This is important for the calves' development and the cow's recovery after lactation.
Step-by-step explanation:
Calves are typically weaned from the cow at around 6 to 8 months of age at the DRU (Dairy Research Unit).
During the weaning process, the calves are gradually introduced to solid food and transitioned away from milk. This allows the calves to develop their rumen, a specialized organ in their digestive system that allows them to digest solid food.
The weaning process is important for both the calves and the cow. It helps the calves transition from a liquid diet to a solid diet, and it also allows the cow to regain her body condition after lactation.
