Özet

Brown-Swiss and Holstein - Friesian calves weaned at 45 days age were separated into 2 groups (32-45 and 46-61 kg) based on their weights on 45 days age. The effect of the weight groups at 4 - months old calves were significant, but, the average weights gain in the periods between birth and 6 months and feed efficiency were insignificant. The correlation between 2 weight groups at weaning and sixth months weight and between weight groups at weaning and daily weight gains between weaning and 6 month of ages were nonsignificant.
