Growth

Birth weight/Weaning weight/Yearling weight/Maternal Milk. Growth traits were evaluated together
in a multi-trait model. As it is recommended for the evaluation of maternally influenced traits, a direct
genetic effect, a maternal genetic effect and a maternal permanent environmental effect were fitted for birth and
weaning weights. Postweaning gain was not considered to be maternally influenced and, therefore, the direct
genetic effect was the only random effect fitted. Yearling weight EPDs were calculated from the EPDs for
weaning weight direct and postweaning gain. The evaluation includes individual weights on embryo transfer
calves out of registered Angus recipient females, provided any other NCE requirements for edited data are met.
Yearling height. Yearling height was evaluated in a multi-trait model including 365-day adjusted yearling weight as a genetically correlated trait.
Scrotal circumference. This multi-trait animal model, includes yearling weight and scrotal performance data.
