摘要
The integration of hormone induction of young ewes,live oocyte collection,in-vitro fertilization and embryo transfer( JIVET),as a major breakthrough in livestock breeding technology,not only solves the problem of low oocytes obtained from adult ewes by hormone induction in production practice,but also significantly improves production efficiency. This technology can reduce the generation interval of cattle and sheep and speed up the acquisition of genes in genetic breeding. The application of this technology can help accelerate the cultivation process,shorten the generation interval,promote the industrialization and improve the economic benefits of beef cattle breed. This paper provides a reference for the research and application of new breeding and propagation techniques of beef cattle.
