摘要
近年来,随着我国饲料资源短缺,人畜争粮现象日益严峻,大量农副类产物资源被广泛应用于反刍动物日粮配方体系。为了进一步提升农副类饲料资源利用效率,降低环境污染,益生菌类产品得到了普遍关注。然而在实际应用过程中,益生菌面临着胃肠原生菌群竞争、瘤胃存活率、菌剂配伍、活菌数、添加方式及阶段等诸多实际问题,导致应用效果良莠不齐。本文重点围绕益生菌的应用功效及作用机制、添加方式及使用时期等方面逐一阐述,以期为实际生产中益生菌的使用提供科学的理论依据和实践指导。
In recent years,with the shortage of feed resources in China and the increasingly serious competition between humans and animals for food,a large amount of agricultural by-products have been widely used in ruminant diet formulation systems.In order to further improve the utilization efficiency of agricultural by-product feed resources and reduce environmental pollution,probiotic products have received widespread attention.However,in the actual application process,probiotics face a series of practical problems such as competition with the native microbial flora of the gastrointestinal tract,survival rate in the rumen,compatibility of probiotic agents,live bacterial count,addition method and stage,resulting in varying application effects.This paper focuses on probiotics function effects and mechanisms of action,addition methods and usage periods,in order to provide scientific theoretical basis and practical guidance for the use of probiotics in actual production.
