益生菌对反刍动物生产及降低甲烷排放的研究进展

随着畜牧业的发展，饲料资源短缺、环境污染等问题日益突出，因此提高饲料资源的消化率成为加快畜牧业发展的关键性问题。研究表明，益生菌具有调节胃肠道微生物群落及其活动的能力，提高反刍动物的代谢水平和营养物质的利用率。益生菌在增强机体的免疫功能和抗病能力以及减少养殖过程中甲烷排放等方面发挥重要作用。本文综述了反刍动物饲粮中添加益生菌对瘤胃微生物及生产性能的积极影响，以期为益生菌在反刍动物健康养殖中应用提供理论依据。

Research Progress of Probiotics on Ruminant Production and Methane Emission Reduction

With the development of animal husbandry, the shortage of feed resources, environmental pollution and other problems are increasingly prominent, so improving the digestibility of feed resources has become a key issue to speed up the development of animal husbandry. Studies have shown that probiotics have the ability to regulate gastrointestinal microbiome and its activities, and improve the metabolic level and nutrient utilization of ruminants. Probiotics play an important role in enhancing the immune function and disease resistance of the body and reducing methane emissions in the breeding process. This paper reviews the positive effects of probiotics supplementation in ruminant diets on rumen microorganisms and performance.
