Abstract
Data are tabulated on the body weights of Korean Black (KB), Brahman, Santa Gertrudis (SG), Brahman X KB, Brahman X (Brahman X KB), SG X KB, and SG X (SG X KB) cattle between birth and 3 mth of age. An orthogonal polynomial including a 3rd-order term accounted for 97% of the total variance in body weight, and the best results were obtained using a 3rd-order term weighted with the reciprocal of error variance and a log transformation of month of age. Prediction equations for body weight are listed for each breed and crossbred group.
