【摘要】：为研究两种不同的葡萄糖氧化酶(GOD)对断奶仔猪生长性能、血清生化指标及养分消化率的影响。试验选取28日龄断奶仔猪90头(平均体重8.41±0.06 kg),随机分为对照组、GOD1组和GOD2组,每组3个重复,每个重复10头,公母各半,试验期30 d。对照组饲喂基础日粮,GOD1组和GOD2组分别在基础日粮中添加0.1%的GOD1和GOD2。结果表明:(1)GOD2组仔猪末重和平均日增重(ADG)分别显著高于对照组和GOD1组9.85%、16.25%和9.11%、15.37%(P㩳0.05),GOD1组和GOD2组仔猪腹泻率分别显著低于对照组85.09%和65.88%(P㩳0.05)。(2)GOD1组仔猪血清尿素氮(BUN)含量显著高于对照组56.84%(P㩳0.05),其他各生化指标统计分析差异不显著(P㧐0.05)。(3)GOD1组和GOD2组仔猪干物质(DM)、粗蛋白质消化率和能量消化率显著高于对照组1.56%、2.26%、1.74%、1.77%、2.32%和1.83%(P㩳0.05)。由此可见,断奶仔猪日粮中添加GOD能够改善仔猪的免疫功能,显著降低腹泻率,促进养分的消化吸收,提高仔猪日增重和饲料转化率。
[Abstract]:To study the effects of two different glucose oxidase (God) on growth performance, serum biochemical index and nutrient digestibility of weaned piglets. 90 weaned piglets (average body weight 8.41 卤0.06 kg),) were randomly divided into control group (GOD1 group) and GOD2 group (n = 10 for each group, male and female) for 30 days. The control group was fed with basal diet GOD1 and GOD2 supplemented with 0.1% GOD1 and GOD2 respectively. The results showed that: (1) the diarrhea rate of GOD2 group was significantly lower than that of control group (85.09%) and GOD2 group (65.88%) compared with control group (9.85%, 16.25%) and GOD1 group (15.37%) and (65.88%) of GOD2 group, respectively. The serum urea nitrogen (bun) content of GOD1 group was significantly higher than that of control group. The dry matter (DM), crude protein digestibility and energy digestibility of GOD1 group and GOD2 group were significantly higher than that of the control group (1.566.84%). The other biochemical indexes were 2.32% and 1.83% (P0. 05). It can be seen that the dietary supplementation of God in weaning piglets can improve the immune function of piglets, significantly reduce the diarrhea rate, promote the digestion and absorption of nutrients, and improve the daily gain and feed conversion rate of piglets.
