Abstract

We tested two postmilking teat dips for efficacy against Staphylococcus aureus and Streptococcus agalactiae using experimental challenge procedures recommended by the National Mastitis Council. The chlorine dioxide teat dip that contained 0.7% sodium chlorite reduced the number of new intramammary infections (IMI) caused by Staph. aureus by 86.6% and reduced new IMI caused by Strep. agalactiae by 88.4%. The 0.5% iodophor teat dip reduced the number of new IMI caused by Staph. aureus by 92.9% and reduced the number of new IMI caused by Strep. agalactiae by 43.4%. Teat skin and teat end conditions were evaluated before and after the study, and no deleterious effects were noted among dipped quarters compared with undipped control quarters for either teat dip.

摘要

我们采用美国国家乳腺炎委员会推荐的实验性攻毒程序，测试了两种挤奶后乳头药浴液对金黄色葡萄球菌和无乳链球菌的功效。含有0.7%亚氯酸钠的二氧化氯乳头药浴液使由金黄色葡萄球菌引起的新的乳房内感染（IMI）数量减少了86.6%，并使由无乳链球菌引起的新的IMI数量减少了88.4%。0.5%的碘伏乳头药浴液使由金黄色葡萄球菌引起的新的IMI数量减少了92.9%，并使由无乳链球菌引起的新的IMI数量减少了43.4%。在研究前后对乳头皮肤和乳头末端状况进行了评估，与未用药浴的对照乳头相比，两种乳头药浴液处理的乳头均未发现有害影响。
