how old does a heifer need to be before breeding
Normally, it is a good idea to breed heifers one month ahead of the main cow herd; so, we need to get heifers that have a mature weight of 1,200 pounds to weigh 780 pounds by the time they are 12-14 months old.ext, use a short breeding season. Do not give heifers more than 75 days to breed. Eliminate heifers that do not conceive during this first breeding season. This helps raise the fertility level of cows retained in the herd.
