Hybrid broilers ascites syndrome occurred in Wuwei city,and caused mortality of 10%~25%.30 infected broilers and healthy broilers were divided into two groups of A and B,the clinic anatomise results showed that compared with healthy birds,the number of red cell,the level of hemoglobin（Hb）,Polycythaemia Compress Volume（PVC） increased significantly.There were no significant difference in serum calcium and phosphorus,however,serum alkalescence phosphate enzyme increased significantly.Pathological examination showed that liver had enlargement,necrosis and hemorrhage,parenchyma cells had denaturalization.Kidney had enlargement and hemorrhage,denaturation of epithelial cells,gizzard layer had lesion,muscle layer had foci of hemorrhage,part of duodenum had hemorrhage,intestine had mucus contents.The cause of this disease lied in absence of oxygen and poisoning,absence of oxygen was the main reason.Poisoning of salt,aflatoxin and Furaxone,high level of protein in feed,absence of vitamin E and Selenium feed protein,which damaged the function of heart and liver,can lead to ascites.%武威市某种鸡场40日龄的肉杂鸡突然发生腹水综合症,死亡率为10%~25%。将患病鸡和相对健康鸡各取30羽,分为A、B 2组,逐一剖检实验,检验结果与健康鸡比较红细胞数、血红蛋白值、红细胞压积均极显著增高;血清钙、血清无机磷无显著变化,而血清碱性磷酸酶活性极显著升高。病理学检验结果表明：肝脏肿大、坏死、出血,实质细胞严重变性;肾脏肿大,出血,肾小管上皮细胞变性;肌胃角质层有溃疡灶,角质膜下的肌肉层有局灶性出血,十二指肠有的有出血,肠内有黏液性内容物。本病病因为缺氧和中毒,以缺氧为主。食盐、黄曲霉毒素和呋喃唑酮中毒、饲料中蛋白含量过高、维生素E或硒缺乏,有损于心脏和肝脏机能,均可能导致腹水产生。
