摘　　要：为了解某规模牧场产后奶牛酮病的发病情况,随机选择产后奶牛86头在产后1 d、7 d、14 d和21 d跟踪检测酮病发生情况,并分析酮病与胎次、泌乳量的相关性。结果显示,奶牛在产后1 d、7 d、14 d和21 d的酮病发病率分别为2.32%、24.42%、11.63%和4.65%;随着奶牛胎次的增加,酮病发病率也有增加的趋势,3~6胎奶牛发病率较高;亚临床酮病和临床酮病奶牛的发病率均随着日产奶量的增加而上升。结果表明,奶牛酮病发病率与胎次和泌乳量存在一定的正相关性。In order to understand the incidence of ketosis in postpartum dairy cows in a large-scale pasture,86postpartum dairy cows were randomly selected to track and detect the incidence of ketosis at 1,7,14 and 21 days postpartum,and the correlation between ketosis and parity and lactation was analyzed. The results showed that the incidence rate of ketosis in cows at 1 d,7 d, 14 d and 21 d after birth was 2.32%,24.42%,11.63% and 4.65% respectively. With the increase of parity,the incidence rate of ketosis increased,and the incidence rate of 3~6 fetuses was higher. The incidence rate of subclinical ketosis and clinical ketosis cows increased with the increase of daily milk production. The results showed that there was a positive correlation between the incidence rate of ketosis,parity and milk yield.
