【摘要】 益生菌制剂具有营养、免疫和抵御感染等功效,是被广泛认可的抗生素添加剂替代品。其中,来自本体动物的原籍菌更易在其宿主体内定植、繁殖及发挥功效,且具有同源性高,针对性强和安全性高等特点,是最理想的益生菌制剂。由于在畜牧生产中抗生素使用引起了种种弊端,因此我国在2020年7月1日起已在饲料生产端全面禁止添加抗生素类促生长添加剂。然而,饲料端抗生素的禁用必然会引起畜牧生产中相关疾病难以控制及动物生长缓慢等一系列问题。而原籍菌作为无毒、无药物残留的新型饲料添加剂,具有促进动物健康生长的益生功能,愈加受到市场追捧。文章综述了相关的原籍菌及其在肉鸡饲料中的应用效果,以期为应用实践提供理论依据。更多还原

【Abstract】 Probiotic preparations are widely recognized alternatives to antibiotic additives because of their nutritional, immune and anti-infection effects. Among them, the autochthonous microbiota from the host animals are easier to colonize, reproduce and exert beneficial effects in the host, and have high homology, strong pertinence and high safety, so they are the ideal probiotic preparations. Due to the abuse of antibiotics in livestock production, china has completely banned the addition of antibiotic in the feed production since July 1st, 2020. However, the prohibition of antibiotics in feed will inevitably cause a series of problems, such as difficulty in controlling related diseases in livestock production and slow growth of animals. As a new type of feed additive without toxic and drug residues, the autochthonous microbiota has the probiotic function of promoting the healthy growth of animal host, and are increasingly sought after by the market. In this article, the relevant autochthonous microbiota and their application effects in broiler feed were reviewed in order to provide theoretical basis for application practice.更多还原
