葡萄糖氧化酶对仔猪生长性能、粪便菌群和血清指标的影响

Effects of Glucose Oxidase on Growth Performance,Faecal Microflora and Serum Parameters of Piglets

本试验主要研究在饲粮中添加葡萄糖氧化酶(GOD)对仔猪生长性能、粪便菌群以及血清生化指标和激素含量的影响。试验选用健康的35日龄仔猪112头,随机分为2个组,每个组4个重复,每个重复14头猪。对照组饲喂基础饲粮,试验组饲喂在基础饲粮基础上添加100 g/t GOD的试验饲粮,试验期35 d。结果表明:GOD组仔猪平均日增重和平均日采食量显著高于对照组(P<0.05),料重比显著低于对照组(P<0.05);GOD组仔猪粪便中沙门氏菌数显著低于对照组(P<0.05);对照组和GOD组间仔猪的血清生化指标(葡萄糖、白蛋白、球蛋白含量和蛋白系数)未出现显著性差异(P>0.05);GOD组三碘甲状腺原氨酸、甲状腺素和生长激素含量显著高于对照组(P<0.05)。试验结果表明,在饲粮中添加100 g/t的GOD可有效改进仔猪肠道健康,提高血清中相关激素含量,改善仔猪生长性能。

The experiment was conducted to investigate the effects of diet supplemented with glucose oxidase （ GOD） on the growth performance, faecal microflora and serum biochemical parameters and hormone con-tents of piglets. A total of one hundred and twelve 35-day-old piglets were randomly assigned to two groups with four replicates per group and fourteen piglets per replicate. Piglets in control group were fed a basal diet, and piglets in test group were fed the basal diet supplemented with 100 g/t GOD. The test lasted for 35 d. The results showed that average daily gain and average daily feed intake of piglets in GOD group were significantly better than those in the control group （ P〈0.05） . The ratio of feed to gain of piglets in GOD group was signifi-cantly lower than that in the control group （P〈0.05）. As for the number of Salmonella in faecal, the GOD group was significantly lower than that in the control group （ P〈0.05） . There was no significant difference be-tween the two groups in serum biochemical parameters （ contents of serum glucose, albumin, globulin, total protein and the ratio of albumin to globulin） （P〉0.05）. The contents of triiodothyronine （T3）, thyroxine （T4） and growth hormone of piglets in GOD group were significantly higher than those in the control group （ P〈0. 05 ） . The experiment indicated that the contents of serum relational hormones, intestinal health and growth performance of piglets can be effectively improved by diet supplemented 100 g/t GOD.
