To improve conception and calves weaned per cow requires several things and one of the most important is deciding when the breeding season should start.
The factors involved in this decision include prices, weather during calving and breeding and feed available during lactation and breeding (which does not receive nearly enough attention).
A shift in the breeding season of between two weeks and two months can make a considerable difference in cow condition at breeding due to increased availability of grass.
The energy requirements of a cow are related to when she is bred—being high during the last 100 days of gestation through breeding. To ensure conception, she needs a rising plane of nutrition starting two weeks before breeding and continuing for three weeks after the breeding season begins. Once bred, her requirements drop but those of the calf continue to rise.
