Surti is one of the well defined dual purpose (meat and milk) goat breeds of south Gujarat. Growth parameters are important for meat as well as milk production of the animals. Early selection of goats on the basis of growth parameters can fetch better economic returns to the farmers. Different molecular tools can help the early selection of the animals. PCR-RFLP is one of the basic techniques extensively used to study the genetic polymorphism in animals. The present study was aimed to study the genetic polymorphism in growth hormone gene (GH) and to find out its association with growth related parameters in Surti goats maintained at Livestock Research Centre, NAU, Navsari. DNA was extracted from the blood samples of 62 animals followed by the gene specific PCR. The digestion of GH PCR products with HaeIII enzyme revealed two genotypes (AB and BB). The genotypic frequencies of AB (422, 366 and 56 bps) and BB (366 and 56 bps) were found 0.8 and 0.2, respectively. The association analysis revealed that the animals with BB genotypes were having higher body weight (P<0.05) at six months of age as compared to the animals with AB genotypes.
