本试验旨在探讨饲粮中添加壳聚糖对早期断奶仔猪生长、腹泻和免疫力的影响。试验选择50头21日龄、平均体重(6.62±0.59) kg的断奶仔猪,随机分为5组,每组10个重复,每个重复1头猪。预试期采用大肠杆菌攻毒(1×10~9个细胞/头),对照组饲喂基础饲粮,试验组分别在基础饲粮中添加50 mg/kg金霉素和200/300/400 mg/kg壳聚糖。试验期21 d。结果表明:1)与对照组相比,各试验组平均日采食量提高(P>0.05),料重比和腹泻率降低,平均日增重分别提高了15.8%、9.2%、16.8%和21.1% (P>0.05).2)与对照组相比,各壳聚糖组血清免疫球蛋白G(IgG)和免疫球蛋白M(IgM)水平以及回肠黏膜白介素1β(IL-1β)、白介素6(IL-6)和肿瘤...

The experiment was conducted to study effects of chitosan on growth performance and immunity in weanling piglets.Fifty piglets with an average body weight of（6.62±0.59） kg were challenged with enterotoxigenic Escherichia coli（1×109 cell per head） during adaptation period and randomly assigned to 5 groups with 10 replicates per group and 1 piglet in each replicate.The piglets in control group were fed basal diet,and the others in experimental groups were fed the basal diet supplemented with 50 mg/kg chlortetracycline,200,300 or 400 mg/kg c...
