Relationship of calpastatin (CAST) genotypes with average daily gain were examined in Iranian Kurdi sheep. The genotypes for CAST were determined by polymerase chain reaction (PCR) and SSCP method. Blood samples were collected from 75 pure bred Kurdi sheep from Kurdi breeding station located in Shirvan, Mashhad. The extraction of DNA was based on Guanidinium Thiocyanate-Silica gel method. Average daily gain from birth to weaning (GBW), from weaning to six months (GWS), six to nine months (GSN) and nine to yearling (GNY) were analyzed by a statistical model comprising SSCP genotypes. Significant effect (p<0.05) of calpastatin genotypes were verified for the GBW.
