摘要
[目的]为奶牛酮病的早期诊断提供依据。[方法]从贵南县2个奶牛场收集135头围产期和泌乳期奶牛的新鲜尿液和乳汁，用试剂法和粉剂法检测其中尿酮和乳酮的阳性变化。[结果]试剂法和粉剂法均可用于奶牛尿酮和乳酮的早期检测。粉剂法具有易配制和携带、使用简单方便等优点，更适用于现场的尿酮和乳酮的阳性检测。尿酮阳性率高而敏感，而乳酮阳性率低。产后尿酮阳性率（34.7％）明显高于产前。酮体阳性率从产后10d开始明显增加，且集中在产后10～20d。[结论]奶牛酮病的早期诊断应在产后10d左右。
[Objective] The aim of the research was to provide the basis for the early diagnosis of dairy cow ketosis. [Method] Fresh urine and milk samples of 135 heads of dairy cows in perinatal period and lactation period were collected from 2 cow farms in Guinan county. The positive changes of urine ketone and milk ketone were determined by using reagent method and powder method. [ Result ]Both reagent method and ketone body powder method could be used in early determination of urine ketone and milk ketone in dairy cows. Powder method had such advantages as being easy to prepare and carry, simple and convenient use, so it was more favorable for the positive determination of urine ketone and milk ketone on the spot. The positive rate of urine ketone was higher and sensitive, but that of milk ketone was low. The positive rate （34.7%） of urine ketone after delivery was obviously higher than that before delivery. The positive rate of ketone body began to increase obviously from the 10th day after delivery and concentrated in the 10th- 20th day after delivery. [Conclusion] The early diagnosis of dairy cow ketosis should be made about on the 10th day after delivery.
