Abstract: The influencing factors involving in reproductive rate of horses include rearing and management level, semen quality of stallions, artificial insemination ways, follicular development and mating age of mares, climatic changes, and so on. According to the above mentioned factors, the practical techniques to improve reproductive rate of horses are put forward： enhancing rearing and management of stallions, providing high quality diet, and maintaining the appropriate body condition for mating, so as to improve semen quality of stallions; enhancing rearing and management of mares before mating and providing more protein feed as well as green and succulent fodder in mating season, so as to maintain their moderate body condition; providing supplementary feeding rationally for pregnant mares to meet their nutritional requirement during the pregnancy period, and taking heat retention measures with plastic warm shed in cold season as well as programmed epidemic disease prevention and treatment measures, so as to reduce the abortion incidence; standardizing artificial insemination operation and preserving frozen semen rationally; using the rectum lead angle of deep fertilization technology when the number of artificially inseminated sperms reach up to 1 ×10^6, so as to reduce the reproductive cost and improve the reproductive efficiency;determining the ovulation time by observation method as well as rectal examination method and mating timely, so as to improve the reproductive rate of horses.
