摘要
试验研究了脲酶抑制剂对肉仔鸡内脏器官及腹水症死亡率的影响,结果表明,在整个试验期内脲酶抑制剂对腹水症的死亡率有明显的控制作用,对照组腹水症死亡率显著地高于试验各组的水平。脲酶抑制剂添加组显著降低了右心室壁重／全心重(RHW／HW)的比例(P<0.05);120mg／kg脲酶抑制剂添加组显著降低了全心重与体重百分比(P<0.05),试验组均显著降低了右心室壁的重量。各处理心、肝、肺重量及肝／体、肺／体百分比无显著差异。
This experiment was designed to study the effect of urease inhibitor on organs weight and ascites syndrome in broilers.The ascites mortality of the control group was higher (P<0.05 or P<0.01)than that of the other three groups. There were no significant difference on heart,liver and lung weight among treatments, but right ventricle weight and the ratio of right ventricle weight to total heart (RHW/HW)were reduced (P<0.05)by urease inhibitor at 21 and 42 days of age.
