| 摘 要： | 为评价鸡肉粉替代鱼粉的可行性，用不同水平国产鸡肉粉(PBM)等蛋白替代基础饲料中的鱼粉，配制成5种等氮等脂的实验饲料(对照组、PBM 12.5、PBM 25.0、PBM 37.5及PBM 50.0)，在室内循环系统饲喂初始体重为(9.25±0.13) g的大口黑鲈8周。结果显示，各处理组大口黑鲈的增重率(WGR)、特定生长率(SGR)和摄食率(FR)均无显著差异。同对照组相比，实验组肝脏超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性显著增加，而丙二醛(MDA)含量显著降低。随鸡肉粉替代水平的增加，肝脏抗炎细胞因子基因(IL-10、TGF-β)相对表达量显著上调，而促炎细胞因子基因(IL-8、TNF-α)相对表达量显著下调，但肝脏的组织结构无显著临床症状变化。此外，随替代水平的增加，肠道抗氧化基因(sod、cat)和肠道紧密连接蛋白基因(Occludin、ZO-1和Claudin-1)相对表达量也显著上调，而血清D-乳酸(D-lac)和脂多糖(LPS)含量显著降低。研究表明，鸡肉粉替代基础饲料(基础饲料中含有40%的鱼粉) 50%的鱼粉不会抑制大口黑鲈的生长，同时还会增强鱼体的抗氧化...
