Separating bulls from the herd after the breeding season insures that you can carry out a controlled breeding program.

If you can limit your controlled breeding season to 90 days, you realize many advantages.

It makes production records easier to keep, thus culling and selection of replacements based on these records easier.

A controlled breeding season also results in a controlled calving season.  More meaningful comparisons of brood cows based on the performance of their calves can be made since calves will be born within about 90 days of each other.

A controlled breeding season also means that better care will be more easily managed in all phases of your operation.
