A natural exposure field trial a with positive control was conducted to evaluate bacteriological efficacy and teat conditioning qualities of an experimental postmilking teat dip. An experimental 1% iodine postmilking teat sanitizer with a 10% emollient system was compared with a 1% iodine plus 10% glycerin teat sanitizer. Efficacy of the two sanitizers was equivalent for all new IMI, major pathogens, and environmental pathogens. The products were not equivalent for efficacy against coliforms and coagulase-negative staphylococci. Fewer coliform IMI were diagnosed in the control group than in the treatment group. Differences were determined for efficacy against coagulase-negative staphylococci in favor of the treatment product. The products were equivalent for all clinical mastitis, including previously existing IMI that became clinical. The products were not equivalent for all or new clinical IMI with major pathogens, all environmental pathogens, or coliforms. Fewer infections were diagnosed in the control group than in the treatment group. Teat end and teat skin conditions improved with the use of the triple emollient, postmilking teat sanitizer under the winter conditions experienced during this field trial.
进行了一项带有阳性对照的自然暴露现场试验，以评估一种试验性的挤奶后乳头药浴液的细菌学功效和乳头调理质量。将一种含有10%润肤剂系统的1%碘试验性挤奶后乳头消毒剂与一种1%碘加10%甘油的乳头消毒剂进行比较。对于所有新的隐性乳房炎、主要病原体和环境病原体，两种消毒剂的功效相当。在抗大肠埃希菌和凝固酶阴性葡萄球菌方面，两种产品的功效不相当。对照组诊断出的大肠埃希菌隐性乳房炎病例比治疗组少。在抗凝固酶阴性葡萄球菌的功效方面确定了差异，治疗产品更具优势。对于所有临床型乳房炎，包括由先前存在的隐性乳房炎转变而来的临床型乳房炎，两种产品的功效相当。对于由主要病原体引起的所有或新的临床隐性乳房炎、所有环境病原体或大肠埃希菌，两种产品的功效不相当。对照组诊断出的感染病例比治疗组少。在本次现场试验期间经历的冬季条件下，使用含三重润肤剂的挤奶后乳头消毒剂后，乳头末端和乳头皮肤状况有所改善。
