Factors that were considered were dammed weight at calving, agro-ecological zone, the season of birth, sex of calves, parity, and dam age. Data from Nguni cows and their calves (n = 826) consisting of calf Birth Weight (BW), Weaning Weight (WW), and Dam Weight at calving were used in this study. Dams were classified according to their weights at calving into high (>385 kg), medium (326-385 kg), and low (}, journal = {American Journal of Animal and Veterinary Sciences}, publisher = {Science Publications} }
