The objectives of this study were to determine the importance of the effects of age of dam (AoD), sex (S) and age of calf (AC), month of birth (M) and the interaction between age of dam and sex (AoD*S) on birth weight (BW) and 205 day adjusted gain from birth to weaning (AWG) of Angus cattle and to estimate correction factors for these effects. Data from 40,915 calves, of which 12,706 were weighed at birth, controlled by the Beef Cattle […]
