试验旨在研究发酵五味健脾颗粒药渣对育肥羊生长性能、抗氧化能力和肠道菌群的影响。选择体重为(25。0±2。0)kg的健康育肥羊18只，随机分为3组，每组3个重复，每个重复2只羊。对照组(C组)饲喂基础饲粮，未发酵药渣组(UF组)在基础饲粮中添加5％未发酵药渣，发酵药渣组(F组)在基础饲粮中添加5％发酵药渣。试验期30d。结果显示，与C组相比，F组平均日增重显著增加31。3％(P＜0。05)，料重比显著降低26。0％(P＜0。05);血清中总抗氧化能力(T-AOC)和过氧化氢酶(CAT)、总超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)活性均显著升高(P＜0。05)。发酵药渣可以增加育肥羊肠道菌群OTU数目，提高菌群物种丰富度和多样性，提高疣微菌门、理研菌科-RC9肠群、密螺旋体属和阿克曼氏菌属等有益菌的丰度。研究表明，饲粮中添加5％发酵药渣能够改善育肥羊生长性能，增强抗氧化能力，提高肠道有益菌的丰度，改善肠道健康。
Effect of fermented medicinal dregs of Wuwei Jianpi granules on growth performance,antioxidant capacity,and intestinal flora of finishing sheep
The study aims to investigate the effects of fermented medicinal dregs from Wuwei Jianpi granules on the growth performance,antioxidant capacity,and intestinal flora of finishing sheep.A total of 18 healthy finishing sheep with a body weight of(25.0±2.0)kg were randomly divided into three groups with three replicates in each group and two sheep in each replicate.The control group(Group C)was fed a basal diet,the unfermented medicinal dregs group(Group UF)was supplemented with 5％unfermented medicinal dregs in the basal diet,and the fermented medicinal dregs group(Group F)was supplemented with 5％fermented medicinal dregs in the basal diet.The experimental period lasted for 30 days.The results showed that compared with Group C,the average daily weight gain of Group F increased significantly by 31.3％(P＜0.05),and the feed conversion ratio decreased significantly by 26.0％(P＜0.05).The total antioxidant capacity(T-AOC)and the activity of catalase(CAT),total superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)were significantly increased in serum(P＜0.05).Fermented medicinal dregs could increase the number of OTU in the intestinal flora of finishing sheep,enhance the species richness and diversity of the flora,and increase the abundance of beneficial bacteria such as Verrucomicrobiota,Rikenellaceae_RC9_gut_group,Treponema,Akkermansia.The study indicates that the addition of 5％fermented medicinal dregs to the diet can improve the growth performance,enhance antioxidant capacity,increase the abundance of beneficial bacteria,and improve intestinal health in finishing sheep.
