| Abstract | Brody's model was used to fit individual growth curves to 74 Hereford and 83 Brangus cows, born in 2 consecutive years and located in two distinct New Mexico range environments. The effects of year of birth, ranch, breed, pregnancy status at 43 months of age and their interactions on growth curve parameters, weights and weight estimates were analyzed. A phenotypic antagonism between mature weight and rate of maturing was found in both breeds, indicating that earlier maturing heifers would have lighter mature weights than late maturing females. |
