摘要
为查明高钠饮水与肉鸡腹水综合征的病因学关系,将240只健康AA肉鸡随机均分为试验Ⅰ、Ⅱ和对照3个组,从8日龄起分别饮用含Na+为0.06%、0.12%和0.00%的饮水,动态对比观察各组肉鸡临床表现、血液红细胞压积(PCV)、红细胞变形性(ED)、右心室(RV)和全心室(TV)的重量比(RV/TV)。结果表明,高钠饮水可以诱发腹水综合征;肉鸡在摄入过量Na+时,出现肺动脉高压(PH)、PCV增加和ED下降等血液流变学特性的改变,促进了腹水综合征的形成。
In order to test the etiological relationship between the hgih natrium drinking water and ascite syndrome in broilers, 240 broilers were divided into treatment groupⅠ(T 1), treatment groupⅡ(T 2) and control group (C) at rondom and 0.06%, 0.12% and 0.00% Na +(from NaCl) given in their drinking water seperately from 8 to 35 day. The broilers′ clinical signs were observed and the packed cell volume (PCV), erythrocyte deformability (ED), the ratio of right ventricular (RV) and total ventricular (TV) measured. The results showed that the ascite syndrome of broilers may be induced by the high concentration of sodium ion ( Na +) in their drinking water. The hemorheological changes including the increased PCV and decreased ED, may be responsible for the occurance of pulmonary hypertension and the formation of ascite syndrome in broilers.
