Cows that get pregnant early in the breeding season tend to stay in the herd longer than those who get bred late in the season. And those cows are also more productive as they produce calves with heavier weaning weights over the long term, according to Brad White, DVM and Bob Larson, DVM. Earlier preg checks may have some economic value as well.
