乳酸菌类微生态制剂在种鸡上的研究进展

Research Progress on the Application of Microbial Ecological Agent Including Lactic Acid Bacteria as the Foundation

乳酸菌类微生态制剂是指以动物乳酸菌（内源菌）为基础，配伍枯草芽孢杆菌和酵母菌（外源菌）而成的一种复合微生态制剂。目前，乳酸菌类微生态制剂因其天然、无污染、无毒副作用，调节肠道菌群、提高动物免疫力和生产性能明显等独特优势，已广泛应用于畜禽养殖业。本文介绍了鸡消化道微生物特点、微生态制剂的作用机理以及微生态制剂在种鸡上的应用效果，为微生态制剂在种鸡上的应用提供理论依据。

Lactobacillus micro ecological preparation including lactic acid bacteria （Intesti- nal bacteria）as the foundation, compounds with Bacillus subtilis and yeast（ added bacteria）. At present, microbial ecological agent including the lactic acid bacteria as the foundation because of its natural, no pollution, non -toxic side effects, and could regulate intestinal flora, improve im- munity and production performance, has been widely used in livestock and poultry. This paper in- troduced the characteristics of the microbes of poultry digestive tract, mechanism of microbial eco- logical agent and its effects on performance in breeding hen, to provide a theoretical basis for the application of microbial ecological agent in breeding hen.
