摘　　要：为研究不同硒源及水平对仔猪生长性能和体液免疫指标的影响,选用35日龄断奶三江白猪仔猪90头,随机分为10组。将纳米硒、酵母硒和亚硒酸钠3种硒源分别以0.1、0.3、0.5 mg·kg^(-1)3个硒水平添加到基础日粮中,配制成试验日粮,基础日粮作对照,试验期为35 d。试验期结束测定血清中的IgG、IgA、IgM、C_3、C_4。结果显示:①饲喂不同硒源及各添加水平仔猪的平均日增重、日采食量、料肉比,各组间差异均不显著(P>0.05);②血清中IgG、IgA、IgM、C_3的水平均以0.5 mg·kg^(-1)的纳米硒组最高,且显著高于纳米硒、酵母硒、亚硒酸钠的0.1 mg·kg^(-1)添加组,显著高于0.5 mg·kg^(-1)的亚硒酸钠组及对照组。C_4的水平以0.3 mg·kg^(-1)的酵母硒添加组最高,且显著高于0.5 mg·kg^(-1)的亚硒酸钠组及对照组。结论:日粮中添加0.5 mg·kg^(-1)的纳米硒能提高机体体液免疫能力。To study the effect of different selenium sources and levels on the weanling pigs growth performance and humoral immune index, 90 35-day-old weaned pigs of San Jiang white pig were selected, and were randomly divided into 10 groups. Nano-selenium, yeast selenium, and sodium selenite were respectively added to basal diet by 0.1,0.3,0.5 mg·kg^-1 as experiment diet, control group is basal diet, experimental period were 35 days. The end of the trial period, the serum IgG,IgA, IgM, C3,C4 were determined. The result show： （1）The average daily gain, average daily feed intake, feed conversion ratio of the piglet by fed different selenium resource, the difference was insignificant（P〉0.05）;（2）The serum IgG,IgA,IgM,C3 level were increased significantly in the 0.5 mg·kg^-1 nano-selenium group and was higher than 0.1 mg·kg^-1 nano-selenium, yeast selenium, and sodium selenite group, and was higher than 0.5 mg·kg^-1 sodium selenite group and control group significantly. The serum C4 content was the highest in 0.3 mg·kg^-1 yeast selenium group and higher than the 0.5 mg·kg^-1 and control group significantly. The conclusion：The 0.5 mg ·kg^-1 Nano- selenium added to daily diet can significantly increase body humoral immunity capability.
