 Abstract
Milk protein polymorphisms were genotyped by polyacrylamide gel electrophoresis (PAGE) from 109 Maiwa and 100 Jiulong yaks. The relationships between milk protein polymorphisms and 3 milking traits were studied. The results showed that -CN, -CN and -La were monomorphic, and -CN and -Lg were polymorphic, with -CN D and -Lg E as dominant genes, respectively. The frequencies of -CN D were 0.8073 and 0.6000 in two populations and -Lg E were 0.9770 and 0.9700. The mean heterozygosities were 0.1021 and 0.1867 in the two populations. No significant effects on milking traits and milk protein compositions were observed except for -CN locus on fat percentage in Jiulong yak.
