Days 1-4: Colostrum[edit | edit source]

For the first 4 days the calf must be fed colostrum from its mother. This is essential in developing the immune system and boosting growth.

Days 5-14: Milk[edit | edit source]

After the colostrum, the calves will be fed milk formula. We want to be feeding 15% of the calf's body weight daily. Slowly begin to provide access to a small amount of starter feed and forage, it has been shown to help early rumen development and makes the transition to hard feed more gradual.

Days 14-28: Milk and starter feed[edit | edit source]

After 2 weeks we will start to feed more starters. We will continue feeding milk twice a day, but we now want to start to transition the cow onto hard feed.

Days 28-42+: Weaning[edit | edit source]

Before we start wean our calf we want it to be consuming at least 1kg of good quality starter meal for at least 3-4 days consecutively. If it isn't eating enough, or is in some way sickly it is better to delay weaning until they are in better condition.

Once our calf is ready to wean, we will gradually reduce the amount of milk it is given in each feed. As we reduce the amount of milk you are giving we should see a corresponding increase in the amount of hard feed consumed. The process should take between 7-14 days and at the end they should be entirely dependent on hard feed.

A calf's immune system can be affected for up to two weeks after weaning, putting them at risk of infection. So during and after weaning it is important to provide a consistent, hygienic environment and not stress the calf.

Days 56+[edit | edit source]

The calf is now fully weaned and living off hard feed and forage. She is ready to leave the calf unit and go into a rearing shed.
