Description

Breeding success depends on the reproductive health of both the cow and the bull. Because a bull is expected to service a number of cows, determining the potential fertility of the bull is much more important than determining the fertility of any individual cow. It is essential to evaluate bulls every year before breeding starts because the fertility of an individual animal can vary from year to year. Surprisingly, only about 28 per cent of bulls in Alberta are evaluated for reproductive fitness.
