The Yunnan Academy of Animal Husbandry and Veterinary Medicine has initiated a project to collect genetic materials from the locally renowned Yanjin buffalo breed, found in Yanjin County and Daguan County of Zhaotong City. This initiative aims to preserve the genetic diversity of the breed, which has been in existence since the Qin and Han Dynasties. The team has collected ear tissues from 24 animals, with the plan to produce frozen semen and embryos. These genetic materials will be stored in a national regional gene bank to ensure the survival and potential future development of the Yanjin buffalo breed.
