摘　　要：本试验旨在研究凝结芽孢杆菌和丁酸梭菌对肉鸭生长性能、屠宰性能、血清生化指标及肠道健康的影响。选择健康的7日龄樱桃谷鸭180只,根据体重均匀分为6组,每组5个重复,每个重复6只。对照组饲喂基础饲粮,BC组饲喂添加凝结芽孢杆菌的试验饲粮,CB组饲喂添加丁酸梭菌的试验饲粮,BC+CB(1∶1)组饲喂添加凝结芽孢杆菌和丁酸梭菌复合菌制剂(以1∶1比例混合)的试验饲粮,BC+CB(1∶2)组饲喂添加凝结芽孢杆菌和丁酸梭菌复合菌制剂(以1∶2比例混合)的试验饲粮,BC+CB组(2∶1)组饲喂添加凝结芽孢杆菌和丁酸梭菌复合菌制剂(以2∶1比例混合)的试验饲粮,试验饲粮中益生菌制剂总添加量均为0.3%。预试期5 d,正试期42 d。结果表明:1)与对照组相比,BC+CB(1∶2)组的12~35日龄、12~49日龄的平均日增重显著提高(P<0.05),BC+CB(1∶2)组和BC+CB(2∶1)组的12~35日龄、12~49日龄的料重比显著降低(P<0.05)。2)各组之间屠宰率、半净膛率、全净膛率、胸肌率、腿肌率、腹脂率差异不显著(P>0.05)。3)BC+CB(1∶2)组和BC+CB(2∶1)组的血清高密度脂蛋白胆固醇、总蛋白、白蛋白含量显著高于对照组(P<0.05),血清谷丙转氨酶活性显著低于对照组和BC组(P<0.05)。各组之间血清低密度脂蛋白胆固醇、甘油三酯、总氨基酸含量和碱性磷酸酶、谷草转氨酶活性差异不显著(P>0.05)。4)BC+CB(2∶1)组的肠道分泌型免疫球蛋白A含量显著高于对照组和CB组(P<0.05)。各组之间肠道肿瘤坏死因子-α和白细胞介素-1β含量差异不显著(P>0.05)。5)与对照组相比,BC+CB(1∶1)组、BC+CB(1∶2)组和BC+CB(2∶1)组的十二指肠和回肠绒毛高度和绒隐比显著提高(P<0.05)。6)与对照组相比,BC+CB(2∶1)组的盲肠鲁森杆菌属(Ruthenibacterium)、未分类的丹毒丝菌科(Erysipelatoclostrichaceae-unclassified)的相对丰度显著提高(P<0.05),盲肠盐单胞菌属(Halomonas)、盐单胞菌科(HalomonadaceThis experiment was conducted to study the effects of Bacillus coagulans and Clostridium butyricum on growth performance,slaughter performance,serum biochemical indexes and intestinal health of meat ducks.A total of 180 healthy 7-day-old Cherry Valley ducks were selected and divided into 6 groups according to their weight,with 5 replicates in each group and 6 ducks in each replicate.The control group was fed a basal diet,the BC group was fed basal diet supplemented with Bacillus coagulans,the CB group was fed the basal diet supplemented with Clostridium butyricum,the BC+CB group(1∶1)group was fed the basal diet supplemented with Bacillus coagulans and Clostridium butyricum(mixed with 1∶1 ratio),the BC+CB group(1∶2)group was fed the basal diet supplemented with Bacillus coagulans and Clostridium butyricum(mixed with 1∶2 ratio),the BC+CB group(2∶1)group was fed the basal diet supplemented with Bacillus coagulans and Clostridium butyricum(mixed with 2∶1 ratio),and the dietary total addition of probiotics was 0.3%.The pre-experimental period lasted for 5 days,and the experimental period lasted for 42 days.The results showed as follows:1)compared with the control group,the average daily weight gain during 12 to 35 days of age and 12 to 49 days of age of BC+CB(1∶2)group was significantly increased(P<0.05),and the feed to gain ratio during 12 to 35 days of age and 12 to 49 days of age of BC+CB(1∶2)group and BC+CB(2∶1)group was significantly decreased(P<0.05).2)There were no significant differences in dressing percentage,semi-eviscerated rate,eviscerated rate,breast muscle rate,leg muscle rate and abdominal fat rate among all groups(P>0.05).3)The contents of high-density lipoprotein cholesterol,total protein and albumin in serum of BC+CB(1∶2)group and BC+CB(2∶1)group were significantly higher than those of the control group(P<0.05),and the serum alanine aminotransferase activity was significantly lower than that of control group and BC group(P<0.05).There were no significant differences in serum low
