Evaluation of a 1% Iodophor Postmilking Teat Sanitizer

Abstract

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.

Avaliação in vitro da eficácia de desinfetantes comerciais utilizados no pré e pós-dippingfrente amostras de Staphylococcus spp. isoladas de mastite bovina

“…Vários trabalhos demonstraram a eficiência dos desinfetantes na redução dos casos de mastite subclínica quando utilizados de maneira adequada (Goldberg et al 1994, Freitas 1998, Jones 1998, Brito 2000.…”

Field Study on Protocols for Evaluation of Teat Skin Conditions

“…One of the most applied methods is visual scoring (Sieber and Farnsworth, 1981;Goldberg et al, 1994a,b;De Vliegher et al, 2003). The application of a scoring system, as proposed by Goldberg et al (1994b) has been more recently modified by Neijenhuis et al (2000). A further development was the availability of digital cameras and the related software for scoring in a more objective and convenient way (Casirani et al, 2002a,b).…”

Ocorrência de Staphylococcus aureus e Escherichia coli O157:H7 em rebanhos leiteiros do Estado de São Paulo

“…Os cuidados higiênicos atualmente recomendados para o período da ordenha baseiam-se em estudos e procedimentos que contemplam o manejo e os equipamentos da ordenha mecanizada (HILLERTON, 1996 Jones (1998), o pré dipping reduz novos casos de mastites causadas por coliformes e estreptococos ambientais. Para Goldberg et al (1994), ocorre uma melhora na condição sanitária da pele do teto e, assim, reduz-se às taxas de infecção da glândula mamária no rebanho. Brito (2000) relata uma redução do número de bactérias na pele dos tetos em mais de 90% após a mamada do bezerro, se os tetos forem cuidadosamente higienizados.…”
