摘　　要：Based on early weaning in calves,hormone induction in young calves,intravital egg collection,in-vitro fertilization and embryo transfer which serve as major breakthroughs in livestock breeding technology,the techniques of hormone induction and in-vitro fertilization were integrated,not only to solve the problem of obtaining oocytes by hormone induction in adult cows in production practice,but also to obviously improve production efficiency.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.
