Early Weaning

A Management Alternative for Improving Heifer and Young Cow Productivity

Abstract

Recent results from our research have shown that early-weaned, first-calf heifers require approximately 50% less energy to achieve and maintain moderate body condition compared to lactating heifers of the same age. Early weaning also has positive implications on the value of the calves post-weaning. The use of early weaning, followed by 100 days of winter annual grazing, produces calves that have recovered from weaning stress and know how to eat. Further, researchers from the University of Illinois have reported that early weaning improved the percentage of calves grading USDA Choice or higher by over 80% compared to normal weaned calves.
