摘要：蛋鸡养殖产业是家禽养殖业的重要组成部分，推动适度规模养殖产业的发展。规模化蛋鸡养殖业发展中会受到多种不良因素的影响，危及蛋鸡生长，经常会引发一系列的肠道疾病。蛋鸡肠道健康能更好地消化和利用各种饲料营养物质，促进鸡健康生长，如果受到多种病原微生物或者养殖管理不当的影响造成鸡的肠道微生态平衡被打破，微生态失衡易诱发一系列肠道疾病和传染性疾病，甚至会危及蛋鸡的健康生长。该文主要论述蛋鸡肠道的主要功能和影响蛋鸡肠道健康的因素，并提出保健措施。

Abstract：The egg industry is an important part of the poultry industry，and the demand for high-quality eggs has increased significantly，which will promote the development of moderate-scale industry. In the development of large-scale layer breeding industry，it will be affected by many adverse factors，endanger the growth and development of layers，often lead to a series of intestinal diseases. The intestinal health of layers can better digest and utilize various feed nutrients，and promote the healthy growth and development of chickens，if affected by multiple pathogenic microorganisms or improper breeding management，the intestinal balance of nature of chickens can be broken，microecological imbalance can easily lead to a series of intestinal diseases and infectious disease，and even endanger the healthy growth and development of layers. This paper mainly discusses the main function of the intestine of layers and the factors affecting the intestinal health of layers，and puts forward the health measures.

0引言

蛋雞相对于其他牲畜动物有特殊的消化系统。在生长发育阶段蛋鸡肠道的健康与否，会对蛋鸡健康生长及生产性能的发挥产生最直接的影响。如果蛋鸡能维持良好的肠道环境，在生长发育阶段能高效利用饲料中的各种营养物质，减少粪便中有机物质的数量，减轻对周边生态环境造成的污染。如果养殖不当或者病原微生物侵入肠道组织中破坏微生态平衡，病原微生物在繁殖中产生大量毒素，不断刺激鸡的肠道异常蠕动，不能很好地消化和利用各种营养物质，引发蛋鸡生长不良，身体瘦弱，尤其是在生产阶段的蛋鸡，如果肠道健康受到影响，产蛋能力显著下降，畸形蛋率显著升高，有时还会引发卵黄腹膜炎，危及蛋鸡健康生长，使大量蛋鸡淘汰处理。……
