摘　　要：在饮水中添加不同剂量的复方中药制剂,研究其对仔猪生长性能及免疫机能的影响。选取48头(15d±2d)"杜×长×大"三元杂交仔猪,按体重和性别随机分为4组,每组12头。在15d,对照组、试验Ⅰ组、试验Ⅱ组和试验Ⅲ组仔猪分别饮用自来水、自来水+0.5g/100mL复方中药制剂、自来水+1.0g/100mL复方中药制剂和自来水+1.5g/100mL复方中药制剂。试验期为30d。所有仔猪于15、29和43d时进行称重,计算平均日采食量、平均日增重和料重比,并观察断奶后腹泻情况。另外,每组选取6头仔猪,于15、28、33、38和43d,经前腔静脉采血,测定部分免疫指标及猪瘟抗体水平。结果显示,饮水中添加不同剂量的复方中药制剂,能显著提高仔猪平均日增重(P<0.01),降低料重比及腹泻率(P<0.01或P<0.05),显著提高T淋巴细胞转化率(P<0.05),同时能够促进猪瘟抗体的产生,提高免疫球蛋白的水平。因此,在饮水中添加适量的复方中药制剂,能够明显改善仔猪的生长性能,增强机体免疫力,促进仔猪的生长。Different dosages of compound Chinese herbal were supplemented to the water to study the growth performance and immune function of piglets.Forty-eight ＇Duroc× Landrance × Yorkshire＇ crossbred piglets（15 d±2 d） were randomly divided into 4 groups of 12 piglets each by weight and sex.At 15 days of age,piglets were drunk with tap water in control group,tap water＋0.5 g/100 mL compound Chinese herbal in group Ⅰ,tap water ＋1.0 g/100 mL compound Chinese herbal in group Ⅱ and tap water ＋1.5 g/100 mL compound Chinese herbal in group Ⅲ respectively.The trial was conducted for 30 d.Body absolute weights（AW）,average daily gain（ADW）,average day feed intake（ADFI） and the ratio of feed to gain（F/G） of all piglets were determined on 15,29,43 days of age and diarrhea rates were evaluated.Blood samples in 6 piglets from each group were taken on 15,28,33,38,43 days of age for measuring some immune indexes and the levels of hog cholera antibody.The results showed that addition of different dosages of compound Chinese herbal to the water increased significantly ADG（P0.01） and decreased F/G and the diarrhea ratio（P0.01 or P0.05）,T-lymphocyte transformation rate and the levels of immune glubulin were increased significantly（P0.01）,and the levels of hog cholera antibody were increased.Compound Chinese herbal supplemented to the water with a proper dosage can increase growth performance,improve the immuce function and enhance the growth of piglets.
