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.
Effect of Periplaneta americana meal on immunity and antioxidation of broliers
Periplaneta americana L. meal was used as a kinds of feed additive to broliers. 495 I -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 Escherchia 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 significantly lower ( P < 0.05). It was suggested that P. americana meal could increase the immunity and antioxidation of broliers.
