Calves get priority access to the best quality grass which helps maintain their performance
With an adequate supply of quality grass, less meal is required giving a cost saving
Calves get used to grazing away from cows to reduce the maternal bond between cow and calf, leading to reduced stress at weaning time
It is relatively cheap to operate - it can be done by installing a creep gate or by raising an electric fence wire
It allows you to feed calves in open troughs rather than a creep feeder. This saves on the cost of buying a creep feeder and on the amount of concentrates fed
CONS
If using the methods or raising the fence line for creep grazing then you could possibly have an issue with the calves getting accustomed to going underneath the fence line.
