奶牛生长与健康性状遗传规律研究进展OA北大核心CSTPCD

Dairy cows can show maximum milk production only when they are raised under the good feeding and management condition and healthy status.The male calves and eliminated cows can be used for fattening and slaughter.Thus,growth and health traits have been paid more and more attentions in dairy cattle breeding.In addition,the mining of candidate genes has provided a solid theoretical basis for the improvement of various economic traits in dairy cattle,and the application of significant SNPs in breeding has greatly shortened the generation interval and effectively improved the genetic progress of livestock breed improvement.In this review,we summarized the research progress for growth and health traits of dairy cattle including the main measure indicators,growth and development rules,and genetic background and candidate genes underlying main common diseases.Thereby,the review provides some reference and theoretical support for gene identification for growth and healthy traits using multi-omics technologies,improvement of the breeding technology system,and cultivation of high-yield,quality and healthy breeding nucleus herd and new lines in dairy cattle.
