"Thank you for the embryo transfer service provided by animal husbandry experts in Inner Mongolia. In the future, people in Shandong can eat more mutton with good meat quality and fresh taste!" A few days ago, a Shandong friend called to say so. According to reports, at the end of December last year, experts from the Inner Mongolia Animal Husbandry Academy were invited to a sheep farm in Shandong Province to use embryo transfer techniques to obtain embryos from the donors of elite meat sheep and transplant them into the recipients of Small Tail Han sheep. Five months later, these small-tailed sheep produced purebred lambs. It is understood that cattle and sheep embryo transfer technology is the most advanced means of breeding cattle and sheep and other herbivorous livestock breeds. This technology can increase the breeding speed of improved breeder sheep and high-producing dairy cows by 5-10 times. Researchers from the Animal Husbandry Academy of Inner Mongolia and the Institute of Animal Husbandry have long said to the author: “Now it is not only in Shandong province, but more than 80% of cattle and sheep embryo transplantation technologies in all parts of the country are promoted by animal husbandry experts in Inner Mongolia. Inner Mongolia’s cattle and sheep embryo transfer technology Services have now reached the leading domestic level. According to reports, after nearly 10 years of research and application, experts in the hospital embryonic transplantation technology has been maturing and perfect, and has provided Shanxi, Shaanxi, Hebei and other provinces and cities to provide cattle and sheep embryos Transplantation technology services have transplanted more than 10,000 embryos of bred sheep each year and transplanted more than 3,000 high-yielding dairy cattle embryos, which has made positive contributions to the development of animal husbandry in the country.
