The Surti is a dual purpose goat breed of Gujarat. The bone morphogenetic protein receptor type 1B (BMPR1B) gene of transforming growth factor beta (TGF-β) superfamily ligands is playing a role in ovulation as well as litter size. Mutation in Exon-6 region of BMPR1B gene with base size 190 bp reported increasing litter size. Based on the known mutation information in goat and sheep, PCR primers were designed to screen polymorphism in total 100 Surti goats, 50 Surti goats from University Farm, Navsari and 50 Surti goats from field units of Southern part of Gujarat. During PCR-RFLP study no polymorphic sites were found for Exon-6 region of BMPR1B on Surti goats. Moreover, the twinning rate was 10% in first parity and higher in subsequent second (62.5%) and third (76.8%) parties.
