摘要(Abstract):
本试验旨在探讨日粮中添加α-亚麻酸对海兰褐商品蛋鸡生产性能和肝脏AMPK的影响。采用单因素试验设计方法,在日粮中分别添加α-亚麻酸0.0%(对照组)、0.5%、1.0%、2.0%、3.0%和4.0%6个处理,每个处理组设5个重复,每个重复3只30周龄海兰褐商品蛋鸡。试验期28d。结果表明:添加α-亚麻酸使平均蛋重增加,添加α-亚麻酸3.0%组增加最大(P<0.05);料蛋比降低,第4周添加α-亚麻酸4.0%组降低最大(P<0.01);肝脏重、肝脏/体重、卵巢重、卵巢/体重、腹脂重和腹脂率减少,均以添加α-亚麻酸3.0%组最低(P>0.05)。AMPK酶活增加,添加α-亚麻酸1.0%组达极显著(P<0.01)。结论:添加α-亚麻酸可提高蛋鸡生产性能,增加AMPK酶活。
