chinois. 试验设对照组、抗生素组和美洲大蠊虫粉组（分别添加2％、1％和0．5％美洲大蠊虫粉）5个处理，每处理设3个重复，将495羽1日龄快长黄羽肉鸡（公鸡）随机分为15组，每组33羽，测定肉鸡免疫功能和抗氧化能力指标．结果表明：（1）6和10周龄鸡均以2％虫粉组的免疫器官指数最高，与对照组的差异均显著（P〈0．05）；淋巴细胞刺激指数以2％虫粉组最高，与其他4组的差异均显著（P〈0．05）；血清球蛋白含量均以2％虫粉组最高，与对照组的差异均显著（P〈0．05），随虫粉剂量的增加有增大的趋势，但差异不显著（P〉0．05）；流感抗体和新城疫抗体效价以2％虫粉组最高，攻毒后鸡的发病率和死亡率以2％虫粉组最低，与对照组的差异显著（P〈0．05）．（2）4、6、8和10周龄鸡的血清总SOD活力均以2％、1％虫粉组最高，与对照组的差异均显著（P〈0．05），血清MDA含量均以2％虫粉组最低，与对照组的差异均显著（P〈0．05），血清GSH．PX活力均以2％、1％虫粉组最高，与对照组的差异均显著（P〈0．05）．可见，日粮中添加美洲大蠊虫粉能提高肉鸡的免疫功能和抗氧化能力．[著者文摘]
Afficher plus [+] Moins [-]anglais. Periplaneta americana L. meal was used as a kinds of feed additive to broliers. 495 1-day-old male broliers were divided into 5 treatments randomly. The results showed that the immunity organ indexes, lymphocyte stimulating index, flu vaccine and new castle disease vaccine antibody titers, content of globulin in serum of 2% P. americana meal treatment were significantly higher than those of the control （P〈0.05）. Morbidity rate and mortality rate after inoculation with Escherichia coli of 2% P.americana meal treatment were significantly lower than those of the control （P〈0.05）. The content of SOD, GSH-PX in 2% and 1% P. americana meal treatments were significantly higher than those of the control （P〈0.05） , while that of MDA were signifieandy lower （P〈0.05）. It was suggested that P. americana meal could increase the immunity and antioxidation of broliers.
