Genetic Polymorphism of Milk Protein and Their Relationships with Milking Performances in Chinese Yak
摘要
Abstract
The milk protein polymorphisms were typed by polyacrylamide gel electrophoresis (PAGE)from 109 Maiwa and 100 Jiulong yaks, and the relationships among milk protein polymorphisms,milking traits and milk protein compositions were studied. The results showed that β -CN, κ -CN and a -La were monomorphic, a sl-CN and β -Lg were polymorphic, the dominantgenes were α s1-CN D and β -Lg E,respectively. The frequencies of α s1-CN D were 0.8073and 0.6000 and β -Lg E were 0.9770 and 0.9700 in two populations respectively. The meanheterozygosities were 0.1021 and 0.1 867 in two populations. No significant effects onmilking traits and milk protein compositions were observed except for u s1-CN locus onfat percentage in Jiulong yak.关键词
