Abstract: Reproductive traits are important economic traits of Bos taurus, which are closely related to production costs and economic benefits.The main reproductive traits include semen quality, follicular development, ovulation, embryo development, calving difficulty, calving interval, etc.The performance of reproductive traits is usually strictly controlled by genes.In-depth excavation and screening of gene functions of important reproductive traits is very important for cattle improvement and breeding, improving production performance and saving production cost.In this paper, the research progress of cattle reproductive traits genes at home and abroad were introduced, such as luteinizing hormone receptor (LHR) and sperm flagella 2 (SPEF2) are related to semen quality;Gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and anti-Müllerian hormone (AMH), bone morphogenetic protein 15 (BMP15), growth differentiation factor 9 (GDF9) are related to follicular formation and ovulation;JY-1, caudal type homeobox 2 (CDX2) and pappalisin 2 (PAPP-A2) are related to the early embryo development and the difficulty of calving;Sialic acid binding Ig like lectin 5 (SIGLEC5), CXC motif chemokine receptor 1 (CXCR1) and forkhead box O1 (FoxO1) are related to calving interval.By summarizing the research on these important reproductive traits related genes, the author introduced the influence of these important reproductive traits genes on cattle production performance, in order to provide theoretical reference for the research on related regulatory factors affecting cattle reproductive traits.
