Percent calf crop weaned is influenced more by man¬agement decisions than by any other single factor in a cow herd, and therefore can be a very important factor in annual returns for a cow-calf operation. Percent calf crop weaned is calculated by dividing the number of calves weaned by the total number of females exposed during the breeding season. As shown in Table 1, as percent calf crop weaned increases, pounds of calf weaned per cow exposed increas¬es and production cost per hundred pounds of calf produced decreases. Increasing weaning weights approximately 50 pounds is equal to an increase of 10% in calf crop weaned.
