To achieve more uniform calves, producers can use tighter calving windows to maximize the number of pregnancies early in the breeding season. Getting most of the cows and heifers bred early in the breeding period improves herd performance.
Investing time and resources to tighten the calving window is beneficial, regardless of the size of operation or the breed of cows.
Research at the University of Nebraska-Lincoln found key performance advantages for calves born during the first three weeks of the calving season.
