摘要: 乳质性状为奶牛重要的经济性状,主要包括乳蛋白量、乳蛋白率、乳脂量和乳脂率等。乳质性状改良是当今遗传育种界的研究热点之一,利用候选基因策略寻找影响乳质性状的功能基因或功能性单核苷酸多态,并将其应用于奶牛乳质性状的分子育种实践已经成为后基因组时代的发展趋势。目前针对乳质性状的功能基因或功能性单核苷酸多态已经开展了大量的研究工作,作者就参与泌乳调控的乳质相关基因、脂肪合成与次生物质代谢通路,以及其他一些与乳质性状相关基因及功能性单核苷酸的研究现状进行简要综述。

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.
