加味四君子汤对肉鸡成活率及免疫器官发育的影响

Impact of Supplementary Sijunzi Decoction on Survival Rate and Immune Organs of Broilers

为研究加味四君子汤对肉鸡成活率及免疫器官发育的影响,选择240只1日龄的肉鸡,随机分为4个处理组(Ⅰ、Ⅱ、Ⅲ、对照),各组饲喂相同的基础日粮,Ⅰ、Ⅱ、Ⅲ组在饮水中分别添加0.5%、1%、2%的加味四君子汤,试验期42d,测定成活率及法氏囊指数、胸腺指数、脾脏指数。结果显示,42d时与对照组相比,试验Ⅰ、Ⅱ、Ⅲ组成活率分别提高5个百分点(P>0.05)、15个百分点(P<0.05)、10个百分点(P>0.05);试验Ⅰ、Ⅱ、Ⅲ组法氏囊指数分别提高7.90%(P<0.05)、22.88%(P<0.01)、14.12%(P<0.05),胸腺指数分别提高34.64%(P<0.05)、52.60%(P<0.01)、30.73%(P<0.05),脾脏指数分别提高6.77%(P<0.05)、21.85%(P<0.01)、6.15%(P<0.05)。由此可见,加味四君子汤能够提高肉仔鸡成活率(P<0.05)和免疫器官指数,且1%的添加量效果最好。

To find out the impact of supplementary Sijunzi decoction on immune organs development of broilers,80 broiler chickens born within one day were selected and divided into 4 groups at random（group Ⅰ ,group Ⅱ ,group Ⅲ and the control group）. With the same basic ration to each group,0. 5 %, 1% and 2 % of supplementary Sijunzi decoction was respectively added in the drinking water of group Ⅰ ,group Ⅱ and group Ⅲ, respectively. The test duration lasted for 42 days to find out the impact of supplementary Sijunzi decoction on survival rate and immune organs development of broilers. The results showed that： compared with control group on 42th day,a） survival rate of group I ,group Ⅱ ,group Ⅲ raised 5（P〈 0. 05）, 15（P〈0.05）, 10 （P〈0.05） percenge points,respectively; b） bursa of fabricius index of group Ⅰ, group Ⅱ and group Ⅲ raised 7.90;（P〈0. 05）,22.88% （P〈0. 01） and 14. 12;（P〈0. 05）;c） thymus index of group Ⅰ,group Ⅱ and group Ⅲ raised 34.64%（P（0.05） ,52.60 %（P〈0. 01）and 30.73%（P〈 0. 05） ;d） spleen index of group Ⅰ,group Ⅱ and group Ⅲ raised 6.77% （P〈0. 05）, 21.85% （P〈0. 01） and 6.15%（P〈0.05）. Supplementary Sijunzi decoction could obviously improve survival rate, immune organ index of broiler chickens and promote their immune organs development, and 1% of Supplementary Sijunzi decoction added in drinking water had the best performance.
