Abstract:

With the development of animal molecular reproduction and embryo engineering technology,the production of genetically superior offspring has become a reality.The embryo engineering technology of animal embryo reproduction has been becoming an important technical approach in animal reproduction fields.The studies of animal embryo breeding include:1) the selection and optimization of embryo engineering technology in animal breeding program;2) the establishment of different systems of animal embryo breeding and the solution exploration of the issues of animal breeding such as inbreeding avoidance;3) the scientific assessment of genetic progress and biosafety in animal embryo breeding.The applications of these technological strategies in animal embryo breeding can be summarized as following:the purebred breeding through expanding group of outstanding individuals;the breeding of new varieties by transgene or gene modification technique;the breeding conservation by using animal germplasm resources.The technology of animal embryo breeding is the development and improvement of the traditional animal breeding theories,as well as the reflection of animal embryo biotechnology application in real animal production.This animal embryo breeding technology has broad application prospects in accelerating the development of animal breeding,the breeding selection,and cultivating new varieties.
