Abstract

Casein polymorphisms are related to milk quality and milk composition. In goat milk, four casein (αS1, αS2, β and k-casein) coded by four autosomal gene were identified. One of these casein is calcium-sensitive casein 2 (αS2-CN) coded by CSN1S2 gene. Presence of seven alleles (A, B, C, D, E, F and O) has been identified at CSN1S2 locus. In this study, three different alleles (CSN1S2F , CSN1S2O and CSN1S2D ) at CSN1S2 locus in Hair goats were investigated by PCR-RFLP method. In total, 70 samples were used from four populations reared in different regions of Antalya. Digestion results with Alw26I restriction enzyme showed that specific F/F genotype (0.057), F/N genotype (0.157) and N/N genotype (0.786) are present where N non F allele (one of A, B, C, D, E and O alleles). Also O and D alleles couldn’t be determined at CSN1S2 locus, according to digestion of NcoI restriction enzyme. F allele at CSN1S2 locus has been shown in Hair goats reared in Turkey for the first time.
