影响家禽后代性别偏移因素的研究进展

Research Progress on Factors Affecting Sex Deviation in Poultry Offspring

采取人工干预性别技术提高经济动物生产效益已取得很大进展,但由于家禽性染色体的特殊性,导致性控技术发展缓慢。母体控制是禽类调控的关键,母体可以自发地调控后代性别,使后代性别比发生偏移。影响母体的因素众多,本文主要对激素引起后代性别发生偏移现象的研究进展进行了详细介绍,分析可以促进家禽产生更多理想后代的方法,为今后相关的研究工作提供参考。

Great progress has been made in adopting technology of human intervention in gender to increase economic animal production efficiency.However,due to the special sex chromosomes in poultry,the sex control technology develops very slowly.Maternal control is the key to the regulation of poultry and the maternal body can spontaneously regulate the sex of the offspring,changing the sex ratio of the offspring.Many factors affect the maternal body.This article focuses on the advances in the research on the phenomenon of offspring sex bais caused by hormones and analyzes methods that can promote more desirable offspring for poultry to provide reference for future related research work.
