摘　　要：产奶性状是奶牛生产中的重要经济性状,由微效多基因决定。影响奶牛产奶性状的基因较多,胰岛素样生长因子-1(insulin-like growth factor-1,IGF-1)基因作为影响奶牛产奶性状的一个候选基因,它的突变可导致其结构和功能发生改变,以及由此引起的产奶性状发生变化。作者就IGF-1的结构与功能及其基因单核苷酸多态性(single nucleotide polymorphisms,SNPs)与产奶性状的相关研究进展进行了综述,旨在为进行奶牛产奶性状的相关研究提供理论参考。Milk production traits were the important economic traits in the cow production, and were determined by many genes with little effect. Insulin-like growth factor-1 （IGF-1） gene as one of many candidate genes for milk production traits,the mutation of IGF-1 gene might result in the change of IGF-1 structure,and the change in milk production traits. The author re- viewed the structure and function of IGF-1 gene and research progress on its single nucleotide polymorphisms and association with milk production traits in bovine,aiming to provide a theoretical reference for relevant studies on milk production traits.
