| 摘 要： | 本试验旨在研究枯草芽孢杆菌(B.subtilis)对罗斯308肉鸡抗氧化能力和免疫性能的影响。试验选用1日龄罗斯308肉鸡216羽,随机分为2组,每组设3个重复。对照组饲喂基础日粮,处理组在基础日粮中添加B.subtilis105CFU/g。饲养试验期为42d。结果表明:与对照组相比,处理组肉鸡日增重提高了12.20%(P0.05),血清与肝脏的总抗氧化能力(P0.05)以及谷胱甘肽过氧化物酶活性(P0.01)显著增加;血清中丙二醛(MDA)、NO及肝脏中MDA水平(P0.05)显著降低。此外,日粮中添加B.subtilis显著提高了肉鸡胸腺指数、法氏囊指数和血清中IgG水平(P0.05),而对脾脏指数及血清中溶菌酶、白介素-2、肿瘤坏死因子-α等指标无显著影响(P0.05)。结果提示,日粮中添加适量B.subtilis可通过提高肉鸡的抗氧化与免疫功能而改善其生长性能。

| Abstract: | This study was conducted to examine the effects of B.subtilis on growth performance,antioxidant and immunity of broilers.A total of 216 day-old Ross 308 broilers were divided into the control group(basal diet) and the treatment group(basal diet supplemented with 105 CFU/g B.subtilis).Each group had three replicates and each replicate included 36 broilers(half male and half female).The experiment lasted for 42 d.The results showed that ADG,T-AOC and the activity of GSH-Px of the treatment group were improved... |
