3. (9 pts.) Weaning weights of purebred calves of the following breeds are: Charolais (C) = 600 lb. Angus (A) = 560 lb. Hereford (H) = 520 lb. Using the %HV1, %HVM, and %HVp values for beef cattle weaning weight in Table 18.2 and presented below, what is the estimated weaning weight of calves produced by mating CxA F1 bulls and AxH F1 cows? Show your calculations. (Hint: Start with the expected performance of the crossbred calves if there was no hybrid vigor.) %HV1 = 5.0%, %HVM = 8.0%, %HVp = 0.0%
