The possibilities of using individual birth weights as weaning criteria in dairy goat farming

Abstract

The aim of the study was to evaluate the possibilities of using individual birth weight of kids as weaning criteria in Saanen and Alpine goats under intensive conditions. A total of 24 does and their 40 kids were divided to weaning groups when the kids reached three (X3) or four times (X4) of their individual birth weights. The experiment design was a 2×2 factorial design with two weaning stages (X3 vs X4) and two breeds (S: Saanen and A: Alpine). The averages of weaning age of the SX3, AX3, SX4 and AX4 kids were determined as 42.75, 42.21, 53.15 and 65.81 days, respectively. The weaning groups and the interaction between weaning and breed had significant effects (P<0.001 and P<0.05, respectively) on weaning age of the kids. The average daily weight gain before weaning was different in weaning groups (P<0.001). On the contrary, the growth performances of the kids until breeding age were not different between groups. The milk yield characteristics of dams in groups were not different. The results indicated that birth weights of the kids can be used successfully for weaning criteria in dairy goats under intensive conditions.
