A postmilking teat dip containing chlorous acid-chlorine dioxide was evaluated by experimental challenge and in two herds under natural exposure. The test product had an efficacy of 78.9% against Staphylococcus aureus and 52.5% against Streptococcus agalactiae in the experimental challenge trial. The product was compared with a 1% iodine product in a 15-mo natural exposure study. Post-dipping with chlorous acid-chlorine dioxide reduced incidence of udder infection by major mastitis pathogens 36.1% when data were combined from the two herds. The 1% iodine and the chlorous acid-chlorine dioxide products were not equivalent for major mastitis pathogens; the test product was more effective. Incidence of udder infection by environmental mastitis pathogens was reduced 36.8% in both herds combined. Efficacy of the two teat dips was equivalent for environmental pathogens.
通过实验性攻毒以及在两个自然暴露的牛群中，对一种含亚氯酸 - 二氧化氯的挤奶后乳头浸液进行了评估。在实验性攻毒试验中，该测试产品对金黄色葡萄球菌的功效为78.9%，对无乳链球菌的功效为52.5%。在一项为期15个月的自然暴露研究中，将该产品与一种1%碘产品进行了比较。当合并两个牛群的数据时，用亚氯酸 - 二氧化氯进行乳头浸液处理后，主要乳腺炎病原体引起的乳房感染发生率降低了36.1%。对于主要乳腺炎病原体，1%碘产品和亚氯酸 - 二氧化氯产品不等效；测试产品更有效。合并两个牛群后，环境性乳腺炎病原体引起的乳房感染发生率降低了36.8%。两种乳头浸液对环境性病原体的功效相当。
