胚蛋接种对家禽生长发育及肠道健康的影响的研究进展

Research progress on effect of embryo egg inoculation on growth and development and intestinal health of poultry

在家禽胚胎发育末期,胚胎代谢活动旺盛增加了在孵化过程中出现营养供应不足的风险,无法完全满足家禽出壳后快速发育的需求,极易对家禽后期生长和生产造成不可逆的损伤。在孵化期为胚胎提供外源营养物质,可促进雏禽在孵化后期及出壳后的生长发育,改善禽苗质量,以达到提高其生产性能、维持肠道健康的效果,将家禽出壳后早期营养调控提前至孵化后期。胚蛋接种作为一种新型超早期营养调控技术可为家禽的生长发育提供新思路。文章从胚蛋接种方法、胚蛋接种营养物质对家禽的生长发育以及肠道健康的影响等方面综述了近年来应用胚蛋接种开展家禽早期营养调控的研究,为家禽的胚期接种的研究提供参考。

At the end of embryonic development of poultry,the vigorous metabolic activity of embryo increases the risk of insufficient nutrient supply in hatching process,which cannot fully meet the needs of rapid development after shell,and is easy to cause irreversible damage to later growth and production of poultry.Providing exogenous nutrients to embryos during the incubation period can promote the growth and development of chicks in later stage of incubation and after emerging from shell,improve the quality of poultry seedlings,to achieve the effect of promoting their production performance and maintaining intestinal health,and advance the early nutritional regulation of poultry after emerging from shell to the later stage of incubation.As a new ultra early nutrition control technology,embryo egg inoculation can provide a new idea for the growth and development of poultry.The paper reviews the research on early nutrition regulation of poultry by embryo egg inoculation in recent years from the aspects of embryo egg inoculation methods,the effect of the nutrients of embryo egg inoculation on the growth and development of poultry and intestinal health,so as to provide reference for the research of embryo stage inoculation of poultry.
