Beef Cattle Adjusted 205-day Weaning Weight The industry standard for weaning age of beef cattle is about 7 months. While producers wean their calves at different times, due to factors such as amount of grazing available, weather conditions, condition of cows, and market factors, the point at which records are compared is at 205 days of age. Weaning weight is a function of growth ability of the individual (genetics) and the milking ability of the dam (growth environment for the calf, but an important consideration in selection of brood cows). Factors for which we adjust include age of the dam, sex of the calf, and age of the calf. Why is each of these important to adjust for? The formula for calculating adjusted 205-day weaning weight is: Birth weight (actual weight at weaning – birth weight) x 205 + Age in days at weaning Why would sex of calf affect adjusted 205-day weaning weight? + age of dam factor + sex of calf

Question
**Beef Cattle Adjusted 205-day Weaning Weight** The industry standard for weaning age of beef cattle is about 7 months. While producers wean their calves at different times due to factors such as amount of grazing available, weather conditions, condition of cows, and market factors, the point at which records are compared is at 205 days of age. Weaning weight is a function of growth ability of the individual (genetics) and the milking ability of the dam (growth environment for the calf, but an important consideration in selection of brood cows). Factors for which we adjust include age of the dam, sex of the calf, and age of the calf. Why is each of these important to adjust for? The formula for calculating adjusted 205-day weaning weight is: \[ \left( \frac{{\text{{actual weight at weaning}} - \text{{birth weight}}}}{{\text{{Age in days at weaning}}}} \right) \times 205 + \text{{Birth weight}} + \text{{age of dam factor}} + \text{{sex of calf}} \] Why would sex of calf affect adjusted 205-day weaning weight?
