Data_Sheet_1_Mixed silage with Chinese cabbage waste enhances antioxidant ability by increasing ascorbate and aldarate metabolism through rumen Prevotellaceae UCG-004 in Hu sheep.docx

Silage is rich in nutrients, which can make up for the lack of seasonal roughage, and has a certain promotion effect on the intensive feeding of ruminants. In addition, silage can maintain the rumen function of ruminants to a certain extent and reduce the risk of rumen acidosis and abomasum translocation. The purpose of this study was to investigate the effects of the mixed silage of Chinese cabbage waste and rice straw (mixed silage) on antioxidant performance, rumen microbial population, and fermentation metabolism of Hu sheep. The 16 healthy Hu sheep (eight rams and eight ewes, 39.11 ± 1.16 kg, 5.5 months) were randomly divided into two groups (the control group and the mixed silage group) with eight animals (four rams and four ewes) in each group. The control group was fed with farm roughage (peanut seedlings, corn husk, and high grain shell) as forage, and the mixed silage group was fed with the mixed silage as forage. The results showed that the mixed silage had no effect on the growth performance of Hu sheep (p > 0.05). Ruminal butyric acid, total volatile fatty acids (TVFA), and ammonia nitrogen (NH3-N) concentration in the mixed silage group were increased, whereas the pH was decreased (p

青贮富含营养，能够补充季节性粗饲料的不足，并对反刍动物的集约化饲养具有一定的促进作用。此外，青贮能够在一定程度上维持反刍动物的瘤胃功能，降低瘤胃酸中毒和网胃移位的风险。本研究旨在探究白菜废弃物与稻草（混合青贮）混合青贮对湖羊的抗氧化性能、瘤胃微生物群落以及发酵代谢的影响。选取16只健康的湖羊（公羊和母羊各8只，体重39.11±1.16公斤，年龄5.5个月）随机分为两组（对照组和混合青贮组），每组8只动物（公羊和母羊各4只）。对照组以农作粗料（花生秧、玉米秸秆和稻谷壳）为饲料，混合青贮组以混合青贮为饲料。结果表明，混合青贮对湖羊的生长性能无显著影响（p>0.05）。混合青贮组瘤胃中丁酸、总挥发性脂肪酸（TVFA）和氨氮（NH3-N）浓度增加，而pH值降低（p
