Abstract: Milk quality traits are very important economic traits of cows,including protein yield,protein percentage,fat yield and fat percentage,and so on. Nowadays,the general goals in present dairy cattle breeding are focused on improvement of milk quality traits. With the research development on functional genes or functional single nucleotide polymorphisms affecting milk production traits,candidate gene strategies have been widely applied in milk quality traits for molecular breeding practicing in post-genomic field. This review will summarize recent findings on the genes and their receptors of regulation of lactation,fat synthesis and secondary metabolism pathways and other pathways.

Key words: cows; milk quality-related genes; milk quality traits
