EVALUATION OF A 1-PERCENT IODOPHOR POSTMILKING TEAT SANITIZER

A natural exposure field trial a with positive control was conducted t o evaluate bacteriological efficacy and teat conditioning qualities of an experimental postmilking teat dip. An experimental 1% iodine postm ilking teat sanitizer with a 10% emollient system was compared with a 1% iodine plus 10% glycerin teat sanitizer. Efficacy of the two saniti zers was equivalent for all new IMI, major pathogens, and environmenta l pathogens. The products were not equivalent for efficacy against col iforms and coagulase-negative staphylococci. Fewer coliform IMI were d iagnosed 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 a ll clinical mastitis, including previously existing IMI that became cl inical. The products were not equivalent for all or new clinical IMI w ith major pathogens, all environmental pathogens, or coliforms. Fewer infections were diagnosed in the control group than in the treatment g roup. Teat end and teat skin conditions improved with the use of the t riple emollient, postmilking teat sanitizer under the winter condition s experienced during this field trial
