摘　　要：排卵数和产羔数是反映绵羊繁殖性状的关键性指标,也是绵羊重要的经济性状,二者属于中低遗传力性状,受基因型、环境和营养状况等多重因素共同影响。由BMP、GDF和AMH等组成的BMP亚家族是TGF-β超家族的重要组成部分,BMPR1B、BMP15和GDF9是目前与绵羊繁殖性能相关性研究最为深入的基因。该文对BMP亚家族成员中提升绵羊排卵数及产羔数的基因的SNP位点进行归纳,总结了这些基因影响繁殖性能的SNP位点的发现,品种、定位、表型,以及对排卵数和产羔率的影响机制,旨在为绵羊多胎品种的选育和高效繁殖提供理论参考。Ovulation number and litter size are both the key indicators reflecting the reproductive traits of sheep and important economic traits of sheep.As being low to medium heritability traits,they are affected by multiple factors such as genotype,environment and nutritional status.The BMP subfamily,which consists of BMP,GDF and AMH,is an important part of TGF-βsuperfamily.BMPR1B,BMP15 and GDF9 are currently the most intensively studied genes related to sheep reproductive performance.In this paper,the SNP loci of genes that increase the number of ovulation and litter size of sheep in BMP subfamily members are summarized.The discovery,location,phenotype of SNP loci of these genes affecting reproductive performance,as well as the mechanism of their effects on the number of ovulation and litter size are summed up.The aim is to provide a theoretical reference for the breeding and efficient reproduction of sheep's multiple births.
