A partnership between the Animal Husbandry Workstation of the Municipal Bureau of Agriculture and Animal Husbandry and Inner Mongolia University has led to the establishment of the State Key Laboratory of Reproductive Regulation and Breeding of Grassland Livestock. The initiative, located in Fengzhen City's Fengdong Zhiying Company, has successfully conducted embryo transfers in Dongfoli raw milk sheep. The project, which started on December 26, 2021, has seen 204 embryos transferred to recipient mothers, with 138 sheep born and 17 embryos cryopreserved. Additionally, 86 cloned embryos were transferred to 8 recipient ewes, resulting in an average of 10.7 embryos per ew. This achievement is a significant step towards breeding a new sheep breed with meat and milk production characteristics in the city.
