【摘要】：为评价解淀粉芽孢杆菌固态发酵黄芪对肉鸡生长及免疫性能的影响,将108只2周龄白羽肉鸡随机分为3组,两试验组在基础日粮中分别添加1%发酵黄芪粉和1%生药黄芪粉,对照组饲喂基础日粮,试验期28 d。试验结束时,统计耗料量,空腹称重,采集血液样品,测定白细胞介素2、γ-干扰素、补体蛋白3和新城疫病毒抗体效价,剖杀试验鸡,取脾脏和法氏囊重重。结果显示,1%发酵黄芪粉能显著提高试验鸡增重(P0.01),降低料肉比(P0.01),试验组鸡的白细胞介素2、γ-干扰素含量与对照组无显著差异(P0.05),补体蛋白3含量显著高于对照组(P0.01),新城疫病毒抗体效价也高于对照组,但差异不显著(P0.05)。结果表明,发酵黄芪能显著促进肉鸡生长,且对肉鸡的免疫性能具有积极作用。
[Abstract]:In order to evaluate the effect of Bacillus amylolyticum solid-state fermentation of Astragalus membranaceus on the growth and immune performance of broilers, 108 two-week-old white feather broilers were randomly divided into 3 groups. 1% fermented astragalus powder and 1% raw drug Astragalus powder were added to the basal diet of the two experimental groups. The control group was fed with basal diet for 28 days. At the end of the experiment, the feed consumption, fasting weight, blood samples were collected, the titers of interleukin 2, interferon 纬, complement protein 3 and Newcastle disease virus antibody were determined, and the chickens were killed. The results showed that 1% fermented astragalus powder could significantly increase the weight gain of the chickens and decrease the feed / meat ratio (P 0.01). There was no significant difference in the contents of interleukin 2 and interferon 纬 between the test group and the control group (P 0.05) and the content of complement protein 3. The titer of Newcastle disease virus antibody was significantly higher than that of control group, and the titer of Newcastle disease virus antibody was also higher than that of control group. The results showed that the fermented Astragalus membranaceus could significantly promote the growth of broilers and had a positive effect on the immune performance of broilers.
