However, due to the lack of quality racehorses in our country, importing a racehorse from abroad can cost several million, tens of millions, or even hundreds of millions of yuan, making this sport unapproachable for the average person because of the high price tag. How to solve this problem? After three years of effort, colleges and scientific research enterprises in the city have provided an encouraging answer. Yesterday, the "Imported Horse Embryo Preparation and Transplantation Technology" project jointly completed by Qingdao Derui Jun Producing Biological Technology Co., Ltd. and Qingdao Agricultural University has passed the scientific and technological achievement appraisal by the expert group of the Shandong Provincial Department of Science and Technology. The appraisal experts unanimously believed that the overall level of the project reached the domestic leading level in the egg donation process, and reached the international advanced level in terms of data collection of imported horse embryos and transplantation success rate. Chinese mares surrogate European foals; Qingdao technology leads the nation. By Gao Na
