Fermented Corn Straw Increases Cellulase Activity, Improves Rumen Fermentation, and Increases Nutrient Digestibility in Yichang White Goats (PRJCA046077)
In this study, we systematically evaluated the effects of replacing corn with fermented corn straw on the carcass index, organ index, calcium and phosphorus contents in tissues, serum biochemical parameters, nutrient digestibility, rumen epithelium and intestinal development, rumen fermentation, and microbial enzyme activity of the rumen contents of Yichang white goats. By combining these approaches with microbial 16S amplicon analysis of rumen fluid and colon contents, along with nontargeted metabolome analysis, we demonstrated the feasibility of substituting corn with fermented corn straw in ruminant feed, providing a new approach for the substitution of energy-supplying feed materials.
