Abstract

In this study, the gene frequencies of \alpha-s_1-casein, \beta-casein, \beta-lactoglobulin and \kappa-casein types were determined in the Brown Swiss cattle which were raised in Türkiye. The frequencies of \alpha-s_1-casein were determined as 0.941 and 0.059 for \alpha-s_1-Ka^B and \alpha-s_1-Ka^C, respectively. Differencies between empricla and theoretical distributions for \alpha-s_1-casein genotypes were non-significant. The frequencies of \beta-casein, were determined as 0.856, 0.134 and 0.009 for \beta-Ka^A, \beta-Ka^B and \beta-Ka^C respectively. Differencies between emprical and theoretical distributions for \beta-casein genotypes were non-significant. The frequencies of \beta-lactoglobulin, were determined as 0.497 and 0.503 for \beta-lgn^A and \beta-lgn^B, respectively. Differencies between emprical and theoretical distributions for \beta-lactoglobulin genotypes were non-significant. The frequencies of \kappa-casein, were determined as 0.521 and 0.479 for \kappa-Ka^A and \kappa-Ka^B, respectively. Differencies between emprical and theoretical distributions for \kappa-casein genotypes were non-significant.
