【摘要】 试验选用28日龄健康断奶仔猪60头,随机分为3组,每组4个重复,每个重复5头猪。对照组饲喂基础日粮,试验1组饲喂基础日粮中添加抗生素(有效含量喹乙醇100g/t,金霉素75g/t,土霉素钙60g/t)的日粮,试验2组饲喂基础日粮中添加1 500g/t的地衣芽孢杆菌的日粮,预饲5d,试验期31d。结果表明,试验2组的终末重显著高于对照组和试验1组(P<0.05),日均采食量高于对照组和试验1组28.57%(P<0.05),日增重分别高于对照组和试验1组43.33%和38.71%(P<0.05),料重比降低10.21%和7.73%;试验2组腹泻率分别比对照组和试验1组降低62.18%和15.71%,试验2组未出现咳喘猪只;试验2组谷丙转氨酶低于对照组和试验1组17.31%和6.18%(P>0.05),谷草转氨酶低于对照组和试验1组34.69%和20.76%(P>0.05),总蛋白含量高于试验1组8.28%(P>0.05),球蛋白含量高于试验1组16.44%(P<0.05);试验2组谷胱甘肽过氧化物酶含量显著高于对照组和试验1组(P<0.05),总抗氧化能力水平显著高于对照组(P<0.05);试验2组免疫球蛋白A、免疫球蛋白G、免疫球蛋白M含量显著高于试验1组(P<0.05),试验2组的白细胞介素4含量显著高于对照组和试验1组(P<0.05),与对照组和试验1组相比试验2组白细胞介素2含量增加(P>0.05)。说明日粮中添加1 500g/t地衣芽孢杆菌在增强仔猪抗氧化能力和免疫力,降低对肝脏的损伤,显著提高仔猪生长性能等方面优于使用抗生素取得的效果。更多还原

【Abstract】 Sixty healthy weaned piglets of 28 days old were randomly divided in three groups,each group of four replicate and five piglets in each replicate.The control group was fed a basal diet,experimental group 1 added Olaquindox 100 g/t,aureomycin 75 g/t,Oxytetracycline calcium 60 g/t in the basal diet,experimental group 2 added Bacillus licheniformis 1 500 g/t in the basal diet.Pre-feeding for 5 days,trial period for 31 days.The results showed that:Compared with the control group and the experimental group 1,the final weight of the experimental group 2 significantly increased(P<0.05),the ADFI wad significantly increased by 28.57%(P<0.05),the ADG was increased by 43.33% and 38.71%,respectively(P<0.05),the F/G was reduced by 10.21% and 7.73%%,respectively;The diarrhea incidence of experimental group 2 was reduced by 62.18% and15.71%than control group and the experimental group 1,but there was no cough and gasp pigs in the experimental group 2;In comparison with the control group and group 1,ALT of group 2 was respectively reduced by 17.31% and 6.18%(P>0.05),AST of group 2 were respectively increased by 34.69% and 20.76%(P>0.05),TP of group 2 was increased by 8.28%than that of group 1(P>0.05),ALB of group 2 was higher than that of group 1(P>0.05),GLB in group 2 was increased by16.44%than that of group 1(P<0.05);The GSH-Px of group 2 was significantly reduced than that of group 1,but the T-AOC was significantly higher than control group(P<0.05);IgG,IgM and IgA of the control group and group 2 were higherthan that of group 1(P<0.05),in comparison with control group and group 1,IL-4 of group 2 was significantly increased(P<0.05)and IL-2 was increased(P>0.05).In conclusion,adding 1 500 g/t Bacillus licheniformis in diets could enhance Antioxidant capacity and immunity,decrease the damage to the liver,and significantly improve the growth performance of piglets.更多还原
