Özet

In this study, the gene frequencies of alpha-(s1)-casein, beta-casein. beta-lactoglobulin and kappa-casein types were determined in the Brown Swiss cattle which were raised in Turkiye.
In this study, the gene frequencies of alpha-(s1)-casein, beta-casein. beta-lactoglobulin and kappa-casein types were determined in the Brown Swiss cattle which were raised in Turkiye. The frequencies of alpha-(s1)-casein were determined as 0.941 and 0.059 for alpha-(s1)-Ka(B) and alpha-(s1)-Ka(C). respectively. Differences between empricla and theoretical distributions for alpha-(s1)-casein genotypes were non-significant. The frequencies of B-casein, were determined as 0.856, 0.134 and 0.009 for beta-Ka(A), beta-Ka(B) and beta-Ka(C) respectively. Differences between emprcal 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 Ign(A) and beta-Ign(B), respectively. Differences between emprical and theoretical distributions for beta-lactoglobuiin 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. Differences between emprical and theoretical distributions for kappa-casein genotypes were non-significant.
