环境温度和日粮能量水平对肉鸡腹水综合征发生的影响

以不同的环境温度（低温和常温）与日粮能量水平（高能量和常规能量）处理商品代肉仔鸡，以探讨这2种因素对肉鸡腹水综合征发生的影响。所用监测指标为学术界公认的反映腹水综合征发生发展的3个参数，即红细胞压积（PCV），腹水心脏指数（AHI）和腹水阳性率。结果表明环境低温处理组，其PCV，AHI和腹水检出率显著高于常温处理组；而日粮的能量水平对这3项指标无显著影响。本试验说明寒冷因子是肉鸡腹水综合征的重要诱发因素，而口粮能量水平在本试验条件下不影响肉鸡腹水综合征的发生发展过程。

Effect of Ambient Temperature and Dietary Energy on Development of Ascites Syndrome in Broiler Chickens

The effects of ambient temperature and dietary energy were investigated on thedevelopment of ascites syndrome in CQmmercial broiler chickens. It was found that low tem-perature induced the significant rises in packed cell volume, ascites heart index and incidenceof ascites. High energy diet did not cause the significant changes in these three parameters.These results showed that exposure to the cold was the important inducer of ascites syn-drome and high dietary energy had no effect on the development of ascites syndrome in broil-er chickens under this experimental conditions.
