[目的]研究在日粮中添加葡萄糖氧化酶和植物血凝素防治仔猪早期断奶腹泻症的效果，探讨其对仔猪生产性能和肠道健康等方面所产生的作用。[方法]选用120头断奶仔猪，随机分为对照组、试验组I和试验组Ⅱ3组，分别饲喂常规断奶仔猪基础日粮、添加0．5％的葡萄糖氧化酶日粮以及添加0．5％的葡萄糖氧化酶和0．1％植物血凝素日粮，采用统一的饲养管理模式。记录每日腹泻次数、采食量、死亡数以及试验开始和结束时每头仔猪空腹体重：计算平均日增重、腹泻率、平均日采食量、饲料转化率及死亡率。[结果]试验期内仔猪平均日增重，试验组I和试验组Ⅱ分别比对照组提高25．0％和26．8％．差异极显著（P〈0．01）；仔猪料肉比，试验组I和试验组Ⅱ分别比对照组下降17．2％和18．7％，差异板显著（P〈0．01）；仔猪腹泻率，试验组I和试验组Ⅱ分别比对照组下降56．0％和65．5％，差异极显著（P〈0．01）；仔猪成活率，试验组I比对照组提高7．4％，差异不显著（P〉0．05），试验组Ⅱ比对照组提高13％，差异极显著（P〈0．01）。[结论]在日粮中添加葡萄糖氧化酶和植物血凝素可明显提高饲料转化效率和仔猪成活卒．明显降低仔猪腹泻率。

[Objective] The control effect of piglet early weaning diarrhea (PEWD) by adding glucose oxidase and phytohemagglutinin to diet was studied to explore the effect on performance and intestinal health of piglet. [Method] One hundred and twenty weaned piglets were randomly divided into three groups, that was controlled, group I and group 11. Under the uniform raising management pattern, piglets in control were fed on routine basal diet; piglets in group I were fed on diet with 0.5% glucose oxidase; piglets in group II were fed on diet with 0.5% glucose oxidase and 0.1% phytohemagglutinin. The diarrhea frequency, feed intake, death number and empty body weight per piglet in the beginning and at the end of the experiment were recorded every day. The average daily gain, diarrhea rate, average daily feed intake, feed conversion rate and mortality were calculated. [Result] Compared with control, the average daily gain of piglets in group I and II were significantly improved by 25.0% and 26.8% respectively(P〈0.01 ); the feed conversion ratio of piglets in group I and I1 were significantly decreased by 17.2% and 18.7% respectively(P〈0.01 ); the diarrhea rate of piglets in group I and II were significantly decreased by 56.0% and 65.5% respectively (P〈0.01); the survival rates of piglets in group I and lI were improved by 7.4% (P〉0.05)and 13% (P〈0.01), respectively. [Conclusion] Adding glucose oxidase and phytohemagglutinin to diet could improve feed conversion rate and piglet survival rate and obviously reduce piglet diarrhea rate.
