摘　　要：为研究超微粉碎天然植物对仔猪生长和健康的影响,试验设置4个组别,分别为:对照组和添加100、200、400 mg/kg超微粉碎天然植物组。试验期间对生长性能、腹泻率、免疫、粪便等指标进行测定。结果表明:添加100、200mg/kg组和400 mg/kg超微粉碎天然植物组仔猪平均日增重分别提高了13.3%(P<0.05)、10%、10%,仔猪腹泻率分别降低了39.4%、41.5%、49.9%(P<0.05)。添加超微粉碎天然植物组仔猪血浆IgG和IgM的水平提高(P<0.05)。添加200、400 mg/kg组仔猪第四周粪便乳酸菌数量提高(P<0.05),仔猪粪便大肠杆菌数量降低(P<0.05)。以上结果表明,在饲料中添加超微粉碎天然植物可以提高仔猪生产性能,通过提高免疫球蛋白和改善肠道微生物来改善仔猪健康。This experiment was conducted to evaluate the effect of superfine grinding herb(SGH) on growth performance and microorganism of piglets. The experiment included the control diet(basal diet),100 mg/kg SGH,200 mg/kg SGH and 400 mg/kg SGH were fed respectively. The effects of SGH comprehensively expounded from growth performance,diarrhea rate,immune index and feces. The results showed that superfine grinding herb supplement(with 100,200,400 mg/kg) increased the weight gain of piglets by 13.3%(P<0.05),10% and 10%,substantially decreased diarrhea rate of piglets by 39.4%,41.5% and 49.9%(P<0.05),increased the level of plasma IgG and IgM(P<0.05),the fecal Lactobacillus count in the fourth week of 200,400 mg/kg groups was increased and the E. coli was decreased(P<0.05). The results indicated that supplement of superfine grinding herb could improve the growth performance and healthy of piglets via immunoglobulin and microorganism improving.
