During three lactational periods (start, middle and end of lactation) of 35 milk cows suffering from mastitis and compared with 34 healthy milk cows of comparable milk production the activity of lactoperoxidase (LPO) and the SCN-content of the milk in each udder quarter were determined. Both components showed no alterations in the subclinical form of the disease. There exists a decrease of the LPO activity in the secretion of ill udder quarters, which will be distinct only in the individual animal and a strong increase of the SCN-content, which is also significant in comparison with the milk of healthy cows.
在35头患乳腺炎的奶牛的三个泌乳期（泌乳开始、中期和末期），并与34头产奶量相当的健康奶牛进行比较，测定了每一个乳腺象限中乳过氧化物酶（LPO）的活性和牛奶中的SCN含量。在疾病的亚临床形式中，这两个成分均未显示出变化。患病乳腺象限分泌物中的LPO活性降低，这仅在个体动物中明显，而SCN含量大幅增加，与健康奶牛的牛奶相比也具有显著性。
