| Abstract: |
Data on 259 pure bred Friesian cows, collected from consecutive seasons, were used to examine the effects of season of calving, parity, weight of cow and sex on calf birth-weight and calf weight. The adjusted correlation coefficients between calf weight at birth and placental weight with weight of cow were detected. No consistent pattern of parity effects on calf birth-weight was observed. Placental weight increased in a linear fashion (P |
