Research Progress on Biological Breeding Technology and Its Application in Livestock and Poultry Breeding
With the development of animal functional genomics and high-throughput omics technology,animal breeding has shifted from traditional animal selection and breeding methods based on animal phenotypic performance to new modern breeding strategies based on molecular biology techniques such as molecular marker technology,transgenic and gene editing technology.Biological breeding is a general term for modern biotechnology breeding and an important symbol to measure the competitiveness of agricultural science and technology,including marker-assisted selection,whole genome selection breeding,transgenic and gene editing breeding,embryo engineering technology system and other breeding methods.As an important means of genetic improvement of livestock and poultry,biological breeding continues to promote the innovation of germplasm resources in China.In this paper,the key technologies and characteristics of biological breeding are introduced in detail,and the research progress of different breeding methods in livestock and poultry germplasm development and genetic improvement is also included.The current situation and problems of livestock and poultry breeding are discussed and analyzed in order to realize the breakthrough and development of core technology of biological breeding.
