Table_2_Mixed silage with Chinese cabbage waste enhances antioxidant ability by increasing ascorbate and aldarate metabolism through rumen Prevotellaceae UCG-004 in Hu sheep.XLSX

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，能够弥补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，降低瘤胃酸中毒和真胃移位的风险。本研究旨在探讨白菜废料与稻草混合青贮（混合青贮）对湖羊的抗氧化性能、瘤胃微生物群落和发酵代谢的影响。选取16只健康的湖羊（包括8只公羊和8只母羊，体重39.11±1.16公斤，5.5月龄），随机分为两组（对照组和混合青贮组），每组8只动物（包括4只公羊和4只母羊）。对照组以农场粗饲料（花生幼苗、玉米皮和高粱壳）作为饲料，混合青贮组则以混合青贮作为饲料。研究结果显示，混合青贮对湖羊的生长性能无显著影响（p>0.05）。混合青贮组的瘤胃丁酸、总挥发性脂肪酸（TVFA）和氨氮（NH3-N）浓度增加，而瘤胃pH值降低（p
