| 摘 要： | 目的]探究2种中药免疫增强剂对肉仔鸡新城疫疫苗免疫效果的影响。方法]将150只1日龄AA肉仔公鸡随机分为对照（CG）组、黄芪（AM）组和枸杞（LB）组,每组50只。CG组饲喂基础日粮,AM组和LB组在基础日粮中分别添加1%AM粉和1%LB粉,分别于14和35日龄测定免疫器官指数,14、21、28、35日龄测定新城疫病毒抗体（NDV-Ab）效价,14和28日龄测定血清免疫球蛋白含量。结果]14日龄时,AM组脾脏指数（SpI）和法氏囊指数（BFI）较CG组分别提高31.17%（P<0.01）和34.86%（P<0.05）;AM组SpI较LB组提高14.12%（P<0.05）;35日龄时,LB组胸腺指数（ThI）和BFI较CG组分别提高14.29%（P<0.05）和9.76%（P<0.05）,AM组ThI、SpI、BFI较CG组分别提高18.37%（P<0.05）、35.84%（P<0.05）、15.85%（P<0.05）,AM组SpI较LB组提高19.92%（P<0.05）。与CG组相比,LB组NDV-Ab效价在28日龄提高34.78%（P<0.05）,AM组NDV-Ab效价在14、21、28 d日龄分别提高118.18%（P<0.05）、75.00%（P<0.05）、56.52%（P<0.05）。与CG组相比,AM组血清免疫球蛋白M（IgM）含量在14和28日龄分别提高15.15%（P<0.05）和11.76%（P<0.05）,血清免疫球蛋白G（IgG）含量分别提高7.50%（P<0.05）和14.15%（P<0.05）;LB组血清IgM含量在14日龄较CG组提高12.12%（P<0.05）,血清IgG含量在28日龄提高11.32%（P<0.05）。结论]日粮中添加1%AM粉或1%LB粉可提高AA肉仔鸡主要免疫器官指数、NDV-Ab效价以及血清IgG、IgM含量,以添加1% AM粉效果较好。

| Abstract: | Objective] To assess the effects of two traditional Chinese medicine immune enhancers on immunological response of broiler chicks to Newcastle disease vaccine. Method] In total, 150 1-day-old male AA broiler chicks were randomly allocated into three groups, a control （CG） group, a Astragalus membranaceus （AM） group, and a Lycium barbarum （LB） group, with 50 individuals in each group. The CG group fed basal diet, while the AM and LB groups were supplemented with 1% AM powder and 1% LB powder in basal diet, respectively. At 14 and 35 days of age, the immune organ indexes were measured. The Newcastle disease virus antibody （NDV-Ab） titer was determined at 14,21, 28 and 35 days of age, and the contents of serum immunoglobulin were evaluated at 14 and 28 days of age. Result] At 14 days of age, the spleen index （SpI） and bursa Fabricius index （BFI） in the AM group were 31.17% （P<0.01） and 34.86% （P<0.05） higher than those in the CG group, respectively, and the SpI in the AM group was 14.12% （P<0.05） higher than that in the LB group. At 35 days of age, the thymus index （ThI） and BFI in the LB group were 14.29% （P<0.05） and 9.76% （P<0.05） higher than those in the CG group, respectively; the ThI, SpI and BFI in the AM group were 18.37% （P<0.05）, 35.84% （P<0.05） and 15.85% （P<0.05） higher than those in the CG group, respectively; the SpI in the AM group was 19.92% （P<0.05） higher than that in the LB group. Compared with the CG group, the NDV-Ab titer of the LB group was increased by 34.78% （P<0.05） at 28 days of age, while that of the AM group was increased by 118.18% （P<0.05）, 75.00% （P<0.05） and 56.52% （P<0.05） at 14, 21 and 28 days of age, respectively. At 14 and 28 days of age, compared with the CG group, the content of serum immunoglobulin M （IgM） in the AM group was increased by 15.15% （P<0.05） and 11.76% （P<0.05）, respectively, and that of serum immunoglobulin G （IgG） was increased by 7.50% （P<0.05) and 14.15% （P<0.05）, respectively. In comparison to the CG group, the content of serum IgM in the LB group was 12.12% （P<0.05） higher at 14 days of age, and that of serum IgG was 11.32% （P<0.05） higher at 28 days of age. Conclusion] Dietary supplementation of 1% AM powder or 1% LB powder improved the major immune organ indexes, NDV-Ab titer, and serum IgG and IgM contents of AA broiler chicks. The effects of 1% AM powder was superior. |
