Abstract

The investigation was planned to study GH gene exon 2-3 polymorphism using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) in Berari goats. GH gene exon 2-3 region was found to be monomorphic on restriction digestion with Hae III which revealed only one genotype AB. The growth performance in terms of body weights of Berari goats was also recorded from birth to 6 months of age at different stages of age.  The least-squares means for overall body weight (kg) were 2.24±0.05, 5.75±0.23, 8.94±0.28, 11.65±0.29 and 18.58±0.43 kg for birth, 1, 2, 3, and 6 month of age, respectively. Sex of kids was a non-significant source of variation for pre-weaning body weights while significant effect (P<0.01) at 6 months. Type of birth (single & twin) of kids was a non-significant source of variation for body weight at different stages of age. Season effect was a non-significant source of variation for body weights at birth, 1 and 2 month of age, however, highly significant effect (P<0.01) on body weights at 3 and 6 months of age.
