| 摘要: |
| 将1日龄艾维因肉仔鸡（雌雄各半）180只在同一鸡舍内饲养至14日龄时随机分成4组，其中Ⅰ,Ⅱ组饲料中按10 g/kg分别添加方剂1和方剂2，连续用药15 d，作为药物预防组；Ⅲ组在饲料中按1.5 g/kg添加肾肿腹水消，连用7 d（按药品要求的预防剂量），作为药物对照组；Ⅳ组饲料中不添加任何药物，作为空白对照组。发病鸡随时采血，其他各组鸡分别在21,28和35 d时采血，测定血清中K+,Mg2+,Fe3+,Cu2+,Zn2+的含量。结果表明，随着肉鸡生长，Ⅰ组鸡血清K+逐渐降低，其余各组均先降低后升高，发病鸡血清K+极显著高于Ⅰ～Ⅳ组；病鸡血清中其他离子与试验组间差异均不显著。因此,血清K+升高可作为肉鸡腹水综合征的诊断指标。 |

| Study on the variation of component in serum with ascites syndrome in broiler |

| Abstract: |
| 180 14-day-old broiler chicks (half male and half female) were randomly divided into 4 groups and reared in the same stall environment.The feed of groupⅠ,Ⅱand Ⅲ was added with drug No.1 for 15 days,drug No.2 for 15 days and a specific drug for ascites at a preventive dose for 7 days respectively,while group Ⅳ consumed no additives.K+,Mg2+,Fe3+,Cu2+,Zn2+ were regularly examined from serum samples.The results showed that the content of K+ in serum in group Ⅱ,Ⅲ and Ⅳ increased first and then decreased,while that of groupⅠcontinually declined and in the end was obviously less than that of ascites broiler.So it is worthwhile to use the content of K+ in serum as referential items for diagnosis. |
