More than 100 embryo sheep have been successfully bred in Heilongjiang Province

Introduction: more than 100 embryo sheep have been successfully bred in the farm of Longda company in Mudanjiang City, Heilongjiang Province recently These fat and big "foreign babies" eat the milk of small and thin local sheep mothers, but there is no blood relationship between them Longda company cooperates with Northeast Agricultural University to cultivate high-quality mutton sheep with embryo bioengineering technology The company has purchased a batch of fertilized frozen sheep embryos from Australia and New Zealand The varieties of these embryos are "Suffolk", "texel" and "Dorset", known as the world's three famous meat sheep They have high meat yield, strong disease resistance, delicate and delicious meat In rural pastures, Professor Li Long of Northeast Agricultural University injected frozen embryos into the uterus of local ewes to carry out embryo transfer in the form of "pregnant by abdomen" Since the beginning of April this year, 137 embryo sheep have been born successfully, all of them have 100% foreign sheep lineage After the birth of these "foreign babies", they grew very fast In more than two months, they weighed 35 kg, 15 kg more than the local meat sheep of the same age Some are still suckling embryo sheep, its height is higher than "mother" In order to make the embryo sheep have a good growth environment, Longda company rented 20 hectares of high-quality pasture as the breeding base and built a factory farm By 2004, the farm will sell 100000 high-quality mutton sheep embryos to the east of Heilongjiang Province and even the northeast of China, and improve the breed of mutton sheep in Heilongjiang Province rapidly through various forms, such as breeding sheep, pregnant by abdomen, hybridization, etc According to reports, embryo bioengineering is the second only to "cloning" of biological genetic technology The difference between embryo sheep and clone sheep is that embryo sheep has no consanguinity with the birth mother of pasture, its own father and mother are the ram and ewe that breed frozen embryo, while clone sheep is the complete repetition of individual and individual, neither father nor mother.
