abstract
The present research has been planned to investigate the genetic polymorphism of BMPR1B and BMP15 genes and their association with the reproductive and growth traits in 30 each of Barbari, Sirohi and Black Bengal goats. The genotyping was carried out by PCR-RFLP technique using restriction enzymes AvaII and HinfI, respectively for BMPR1B and BMP15 gene. The amplified PCR products of size 190 bp and 141 bp were obtained for BMPR1B and BMP15 gene, respectively. PCR-RFLP analysis of both these genes showed monomorphic pattern in all the three breeds of goat, which revealed only one type of uncut banding pattern of 190bp for BMPR1B and 141bp for BMP15 gene. Therefore, the association study with different economic traits could not be performed at BMPR1B/AvaII and BMP15/HinfI genes loci. The body weights from 15 to 90 days and 3 to 6 months of age were significantly (p<0.05) higher in Sirohi goats followed by Barbari and Black Bengal. Minimum age at sexual maturity (days) was recorded in Black Bengal goats followed by Sirohi and Barbari goats. Significantly (P<0.05) lower age at first kidding was recorded in Black Bengal followed by Barbari and Sirohi goats. The mean litter size at first and second kidding (Nos.) was significantly (P<0.05) higher in Black Bengal as compared to Barbari and Sirohi goats. Monomorphism was observed in the BMPR1B/AvaII and BMP15/HinfI genes in screened populations of Barbari, Sirohi and Blank Bengal goats.
