Effect of Exogenous Complex Non-Starch Polysaccharidases supplementation on growth performance, rumen fermentation and microflora of fatting sheep and decreased inflammation by high concentrate diet

We hypothesized that a specific combination of NSPases (i.e., cellulose, xylanase and mannanases) apply in the high concentrate diet would break cell wall, improve rumen fermentation and growth performance of sheep. The aim of this study was to evaluate the effects of NSPases on intake and total apparent digestibility of nutrients, rumen fermentation, and rumen microbes composition of sheep.

本研究假设，将特定组合的非淀粉多糖酶（Non-Starch Polysaccharidases，NSPases）——即纤维素酶、木聚糖酶与甘露聚糖酶——添加至高精料日粮中，可破坏植物细胞壁，改善绵羊的瘤胃发酵与生长性能。本研究旨在评估非淀粉多糖酶对绵羊采食量、营养物质总表观消化率、瘤胃发酵以及瘤胃微生物组成的影响。
