摘　　要：试验旨在研究复合植物提取物对山麻雏鸭生长性能、免疫器官指数和血清免疫指标的影响,选取健康1日龄山麻雏鸭1200只,单因素随机分组设计分为4组,每组300只,每组6个重复,每个重复50只。对照组饲喂玉米-豆粕型基础日粮,试验A、B和C组分别在基础日粮中添加0.5%、1.0%和2.0%的复合植物提取物。试验期42 d。结果表明:(1)42 d时,试验组平均日增重均极显著高于对照组(P<0.01),试验B、C组料重比显著低于对照组(P<0.05)。(2)与对照组相比,21 d时,试验C组脾脏指数显著升高(P<0.05),试验B组法氏囊指数显著升高(P<0.05),且显著高于其他2个试验组;42 d时,试验B、C组胸腺指数均显著升高(P<0.05);试验A、B组法氏囊指数均显著升高(P<0.05)。(3)与对照组相比,21 d时,试验B组IgM、白细胞介素-4(IL-4)含量显著增加(P<0.05),试验A、B组IgG含量均显著增加(P<0.05);试验C组白细胞介素-2(IL-2)、干扰素-γ(INF-γ)含量均显著增加(P<0.05);42 d时,试验组IgM、IgG含量均显著增加(P<0.05),试验B、C组IL-4和INF-γ含量均显著增加(P<0.05)。(4)试验组新城疫(ND)抗体水平均显著高于对照组(P<0.05)。由此可见,日粮添加不同比例的复合植物提取物能够促进山麻雏鸭生长性能、免疫器官生长发育,调节免疫功能和提高新城疫抗体水平,以1.0%比例效果最佳。The experiment was conducted to study the effects of compound plant extracts on growth performance,immune organ index and immune index in Shanma ducklings.A total of 1,200 healthy 1-day-old Shanma ducklings were selected and divided into 4 groups by single factor random grouping design,with 300 ducklings in each group and 6 replicates in each group,50 ducklings in each replicate.The control group was fed with corn-soybean meal basal diet,and groups A,B and C were fed with 0.5%,1.0% and 2.0% compound plant extracts respectively.The experimental period was 42 days.The results showed that:(1)at 42 days,the average daily weight gain in experimental groups was significantly higher than that in control group(P<0.01),while the feed-weight ratio of Group B and C was significantly lower than that of the control group(P<0.05).(2)On the 21st day,compared with the control group,the spleen index of Experimental Group C was significantly increased(P<0.05),and the Bursa index of Experimental Group B was increased(P<0.05),significantly higher than that of the other two experimental groups.At day 42,compared with the control group,the thymus index in Group B and C was significantly increased(P<0.05),so was the Bursa of Fabricius Index in Group A and B(P<0.05).(3)At day 21,the content of IgM and IL-4 in test group B was significantly higher than that in control group(P<0.05),and the content of IgG in Test Group A and B was significantly higher than that in control group(P<0.05),the contents of IL-2 and INF-γ in Group C were significantly elevated(P<0.05).At day 42,the contents of IgM and IgG in the three groups were all significantly increased(P<0.05),the levels of IL-4 and INF-γ in Group B and C were significantly increased(P<0.05).(4)The ND antibody levels in three groups were significantly higher than those in the control group(P<0.05).It can be seen that the addition of different proportions of compound plant extracts to the diet can promote the growth performance,immune organ growth and development,regulate immune function
