Genetic Variation of Growth Hormone Gene and Its Relationship with Milk Production Traits in China Holstein Cows
China Holstein Cows Growth Hormone Gene PCR-RFLP Genetic Polymorphism Milk Production Traits
2016/4/20
Associations were analysed between polymorphisms localized in intron 3 of the growth hormone gene (GH-MspI) and milk production traits of 543 China Holstein cows. A PCR-RFLP method was used for identi...
