Abstract
We performed the genome-wide association study of estimated breeding values for milk production traits in Russian Holstein and black-and-white cattle population. The join dairy cows’ population of Moscow and Leningrad regions was used to create a common reference group of animals to obtain the genomic breeding values. We identified breeding and genetic parameters for milk yield for 305 days of lactation, milk fat and protein content, milk fat and protein yield. We found several high-significant conservative mutations associated with milk fat content (e.g., DGAT1, P = 6.8 ? 10−22), as well as a 1.5 Mb locus on BTA14. Our results will be used to develop a genomic evaluation programs, aimed to improve eco- nomically important traits in dairy cattle in Russia.
