Abstract

Isozymes of lactate dehydrogenase (LDH) in the skim milk of 109 Maiwa yaks and 100 Jiulong yaks were assayed by native PAGE. Only one band (LDH 1) was observed on the gel for each sample. Four genetic variants of LDH 1 were detected: A, B, C and D according to their mobilities from fast to slow on the gels. The D variant was observed only in Jiulong yaks. The C variant was predominat in the two breeds. There existed significant difference of the distribution of phenotypic frequency of LDH 1 between Maiwa yaks and Jiulong yaks ( P 0.01).
