摘要 试验选择500只同品种同日龄的AA肉仔鸡,随机设置10个重复组,每重复组50只鸡。各重复组饲喂同一日粮,在同一环境条件下饲养管理,自由采食和饮水。饲养期分为0~3和4~8周龄2个阶段,同一阶段喂饲同一日粮。分别在肉鸡发育3、4、5、6、7及8周龄末,每重复组随机抽取10只鸡进行屠宰,并分离皮下脂肪和腹腔内脂肪。用电子计量法分别称量皮下脂肪和腹腔内脂肪的质量。荧光定量RT-PCR法观测ADPN的表达。试验结果显示:在3周龄到6周龄期间皮下脂肪和腹腔内脂肪含量与脂联素基因表达呈正相关(r**=1.036,P〈0.01;r**=1.182,P〈0.01)。7周龄到8周龄期间皮下脂肪和腹腔内脂肪含量与脂联素基因表达呈负相关(r*=-0.946,P〈0.05;r*=-0.987,P〈0.05)。
