摘　　要：为了研究肉鸡肺动脉高压综合征(PHS)的抗病育种情况,试验采用静脉注射纤维素颗粒的方法诱发PHS,比较发病前后非易感组肉鸡和易感组肉鸡右心室与全心室重量比(RV/TV)值,心电图Ⅱ导联S波、R波和RS综合波波幅,红细胞比容(PCV),血红蛋白(HB)和血清蛋白含量。结果表明:静脉注射纤维素颗粒明显提高了肉鸡PHS的发病率。发病后腹水组肉鸡PCV、HB含量和RV/TV值升高,血清蛋白含量降低,心电图Ⅱ导联S波、R波和RS综合波波幅均升高,符合肉鸡PHS的特点;但发病前易感组肉鸡与非易感组肉鸡相比,PCV、HB含量、血清蛋白含量和心电图Ⅱ导联S波、R波和RS综合波波幅均无显著差异。This experiment uses the method of intravenous injection of cellulose particles to induce PHS,investigating the differences in right ventricular to total ventricular ratio（RV/TV）,the amplitude of S wave,R wave and RS complex wave in lead Ⅱ ECG,the levels of PCV,and the contents of HB,and serum protein between the non-diseased group and the diseased group.The results showed that the method significantly enhanced the risk of broiler PHS disease.After the incidence of PHS,the values of PCV,HB and RV/TV were increased,but the serum protein was decreased,and the amplitudes of S wave,R wave and RS complex wave in lead Ⅱ ECG were also increased in the group with ascites.These conformed to the characteristics of PHS in broilers,but there was no distinctive difference between the non-diseased group and the diseased group before the incidence of PHS.
