摘　　要：本试验旨在研究菌酶协同发酵绵马贯众对断奶仔猪生长性能、血清生化指标和抗氧化能力的影响。采用单因素随机化设计,挑选体重相近的(28±2)日龄断奶仔猪160头,随机分为5个组,每组4个重复,每个重复8头仔猪。对照组饲喂基础饲粮,原粉组在基础饲粮中添加0.6%绵马贯众原粉,菌酶协同组分别在基础饲粮中添加0.3%、0.6%、0.9%的菌酶协同发酵绵马贯众。试验期为28 d。结果表明:1)与对照组相比,0.6%和0.9%菌酶协同组平均日增重显著提高(P<0.05),0.6%菌酶协同组平均日采食量显著降低(P<0.05),0.3%、0.6%和0.9%菌酶协同组料重比显著降低(P<0.05)。2)与对照组相比,0.3%、0.6%和0.9%菌酶协同组血清免疫球蛋白A、补体3、补体4和溶菌酶含量显著提高(P<0.05),血清白细胞介素-1、白细胞介素-6含量显著降低(P<0.05);0.6%和0.9%菌酶协同组血清免疫球蛋白G含量显著提高(P<0.05)。3)与对照组相比,0.3%、0.6%和0.9%菌酶协同组血清碱性磷酸酶活性和白蛋白含量显著提高(P<0.05),0.3%、0.6%和0.9%菌酶协同组血清谷草转氨酶活性和尿素氮含量显著降低(P<0.05)。4)与对照组相比,0.3%、0.6%和0.9%菌酶协同组血清肌酸激酶、乳酸脱氢酶活性和葡萄糖含量显著降低(P<0.05)。5)与对照组相比,0.3%、0.6%和0.9%菌酶协同组血清总抗氧化能力、超氧化物歧化酶活性和还原型谷胱甘肽含量显著提高(P<0.05),0.6%和0.9%菌酶协同组血清丙二醛含量显著降低(P<0.05)。由此可见,饲粮中添加0.6%的菌酶协同发酵绵马贯众能提高断奶仔猪生长性能,增强断奶仔猪抗氧化能力和免疫功能。The aim of this experiment was to investigate the effects of Dryopteris crassirhizoma fermented with bacteria and enzymes on growth performance,serum biochemical indexes and antioxidant capacity of weaned piglets.A single factor randomized design was adopted,and one hundred and sixty(28±2)-day-old weaned piglets with similar body weight were randomly divided into 5 groups with 4 replicates per group and 8 piglets per replicate.Piglets in the control group were fed a basal diet,piglets in the original powder group were fed the basal diet supplemented with 0.6%Dryopteris crassirhizoma original powder,and others in bacteria and enzymes synergy groups were fed the basal diet supplemented with 0.3%,0.6%and 0.9%Dryopteris crassirhizoma fermented with bacteria and enzymes,respectively.The experimental period was 28 days.The results showed as follows:1)compared with the control group,the average daily gain of 0.3%,0.6%and 0.9%bacteria and enzymes synergy groups was significantly increased(P<0.05),the average daily feed intake of 0.6%bacteria and enzymes synergy group was significantly decreased(P<0.05),and the feed to gain ratio of 0.3%,0.6%and 0.9%bacteria and enzymes synergy groups was significantly decreased(P<0.05).2)Compared with the control group,the contents of immunoglobulin A,complement 3,complement 4 and lysozyme in serum of 0.3%,0.6%and 0.9%bacteria and enzymes synergy groups were significantly increased(P<0.05),and the contents of interleukin-1 and interleukin-6 in serum were significantly decreased(P<0.05);the serum immunoglobulin G content of 0.6%and 0.9%bacteria and enzymes synergy groups was significantly increased(P<0.05).3)Compared with the control group,the serum alkaline phosphatase activity and albumin content of 0.3%,0.6%and 0.9%bacteria and enzymes synergy groups were significantly increased(P<0.05),and the serum glutamic oxaloacetic transaminase activity and urea nitrogen content of 0.3%,0.6%and 0.9%bacteria and enzymes synergy groups were significantly decreased(P<0.05).4)Compared with the contr
