The aims of the present study were to relate intramammary infection (IMI) occurrence and somatic cell count (SCC) with teat-end condition (TEC) and udder cleanliness (UC). Milk samples from 1931 teats were evaluated according to the presence of IMI and SCC. Scores were applied to teats according to the TEC and to UC. Teats ends with a very rough ring had the largest number of IMI when compared to the other three categories, as well as animals with dirtier udders. The change in a TEC score increased by around 30% the chance of IMI. Also, the chance of the animal developing IMI increased by approximately 47% when the UC score increased. No significant association between both scores and quarter SCC was found. It can be concluded that animals with very rough teat end rings and very dirty udders have a greater predisposition to IMI.
本研究的目的是研究乳腺炎（IMI）的发生和体细胞计数（SCC）与乳头末端状况（TEC）和乳房清洁度（UC）的关系。根据 IMI 和 SCC 的存在，评估了 1931 个乳头的奶样。根据 TEC 和 UC 给乳头评分。与其他三个类别相比，具有非常粗糙环形物的乳头末端发生 IMI 的数量最多，而且奶牛的乳房也更脏。TEC 评分的变化使 IMI 的发生几率增加了约 30%。同样，当 UC 评分增加时，动物发生 IMI 的几率大约增加了 47%。未发现这两个评分与四分位 SCC 之间存在显著相关性。可以得出结论，具有非常粗糙的乳头末端环和非常脏的乳房的动物更容易发生 IMI。
