Abstract:

AA肉鸡180羽随机等分为对照组(C)和试验组(A、B)。参试鸡14日龄前常规饲养。14日龄后C组鸡继续常规饲养;A、B组鸡舍温度按每日1~2℃由25℃逐步降至12℃,同时日粮中添加15mgkg-1三碘甲状腺原氨酸(T3)以诱发腹水综合征;B组自14日龄起至试验结束在日粮中再添加1%(质量分数)L精氨酸。分别于3,4,5,6,7周龄测定各组肉鸡肺动脉平均压(mPAP)、红细胞压积、右心全心比及血浆一氧化氮(NO)水平,并记录腹水发病率。结果发现低温添加T3处理后,A组肉鸡腹水发病率增加,mPAP在5周龄时升高,右心全心比在6周龄时升高;B组肉鸡腹水发病率明显低于A组,血浆NO水平高于A组(P<001),mPAP在6周龄时升高,右心全心比在7周龄时升高,此变化比A组晚一周出现。上述结果提示,日粮添加精氨酸后血浆NO水平升高,可能在一定程度上抑制了肺动脉高压的形成,因而在一定程度上降低了腹水综合征发病
