The College of Life Sciences at IMU, together with the Provincial and Ministerial Jointly Built National Key Laboratory of Grassland Livestock Reproductive Regulation and Breeding, has collaborated with the Xilingol League Bureau of Science and Technology to tackle key technological challenges related to the high fertility of Ujimqin sheep, who have independently designed and developed the world's first low-density SNP genetic chip for detecting the fertility of Mongolian sheep breeds. Using modern molecular biology and whole-genome sequencing technologies, we have identified more than 10 candidate genes specific to the Mongolian sheep breed with over 20 mutation sites. This provides crucial technical support for the cultivation of new breeds of Ujimqin sheep and Sunite sheep with high fertility, achieving a "breakthrough" in key technologies for the mutton sheep breeding industry. It plays a significant role in addressing the “cutthroat issue” of low fertility in Ujimqin and Sunite sheep, protecting local superior breed resources, and promoting the cultivation and popularization of highly prolific Ujimqin and Sunite sheep. It also helps farmers and herders reduce the number of breeding females, alleviate ecological pressure on the grasslands, lower the cost of sheep farming, and enhance the production efficiency of the  mutton sheep industry.

Since the project implementation of the "Xilingol Sheep - High Prolificacy Multiple Births Ujumuqin Sheep New Breed Cultivation" "the open competition mechanism to select the best candidates " , genetic testing has been conducted on 5,455 Ujumuqin sheep and 3,755 Sunite sheep across five areas including Xilinhot City, East Ujumuqin Banner, West Ujumuqin Banner, Sunite Left Banner, and Sunite Right Banner. Additionally, over 500 Ujumuqin sheep have been artificially inseminated, and 902 embryo transfers have been performed, along with 773 embryo transfers for Sunite sheep. To date, two core groups of highly prolific Ujumuqin sheep, totaling 596 individuals and two core groups of highly prolific Sunite sheep, totaling 440 individuals have been cultivated. The research team has published more than 10 related papers, applied for eight national invention patents, and has been granted two national invention patents.
