摘要：

Genetic variants of alpha(s1)-, beta-, and kappa-caseins and of beta-lactoglobulin were studied with PAGE and isoelectric focusing in milk samples of 101 Hungarian Spotted and 120 Hungarian Grey cows. Gene frequencies and genotypic frequencies were estimated. Significant differences in gene frequencies between the two breeds were observed at the kappa-casein and beta-lactoglobulin locus. The variants beta-casein C, kappa-casein C, and beta-lactoglobulin D were not found in Hungarian Grey cows. On immobilized pH gradient, isoelectric focusing gels containing carrier ampholytes, a new unidentified protein band appeared near beta-lactoglobulin B in about 10% of the milk samples of Hungarian Grey cattle.
