摘　　要：2012年1月～2013年8月，笔者对石河子地区12个规模场奶牛蹄叶炎发病情况进行了调研、奶牛蹄叶炎平均发病率为9．12％～19．78％，淘汰率为8.1％～15．3％，犊牛、青年牛发病率为0。临床调查结果发现蹄叶炎发病有品系间差异，体重较大的加拿大系荷斯坦牛发病率高于澳大利亚系荷斯坦牛（P〈0．01）；1～2胎奶牛发病率最高；发病时间多在产后3～19日内；发病季节在冬季的12月～次年5月间。临床病牛产奶量显著下降（P〈0．01），患病牛血液丙氨酸氨基转移酶显著升高（P〈0．05）、葡萄糖含量显著降低（P〈0．05）、组胺水平较健康奶牛显著升高（P〈0．01）、高精料低粗纤维饲养是发病的重要因素；运动场凸凹不平、无牛床的奶牛场病牛数量有增长的趋势。In this study, a total of 12 cattle farms were investigated for cattle laminitis from January 2012 to August 2013. The morbidity and elimination rate of cows for laminitis were 9.12%-19.78% and 8.1%-15.3%, respectively. There were pertinency between breed and illness. Because of the cows weight, the morbidity of Canada strains Holstein cow was higher than Australia strains（P〈0.01）. The illness mainly occur in December to May, and the milk yield of cow fall markedly with the lactation. The levels ofAlanine aminotransferase was higher than normal（P〈0.05） and blood glucose was lower（P〈0.05）. It was the main cause for overfeed commercial feed in diet for milk cow. The conditions of ground and cow bed were closely related to laminitis.
