[QUOTE="hillsdown, post: 715106, member: 5106"] Try this link it explains it quite well. [url=http://www.albcia.com/documents/information%20tab/PerfTraitsBfCattle.pdf]http://www.albcia.com/documents/informa ... Cattle.pdf[/url] Weighing Cows and Calves Performance test guidelines recommend calves be weighed when they are close to 205 days of age. The accepted age range is 160 to 250 days of age. Weighing calves less than 160 days of age will cause an over-estimation of adjusted weaning weights. Weighing calves over 250 days of age will result in under estimation of adjusted weaning weights. Therefore, data from calves outside the age range is not figured into the herd average. An additional weigh day may be necessary if the herd is on a split calving season or on an extended calving season. It is recommended to also weigh the cows at the same time the calves are weighed. The cow weight will be used to identify which cows wean a high percentage of their body weight. Generally, cows that wean a high percentage of their body weight are more efficient and profitable than cows that wean a low percentage of their body weight.
