The process of pre-milking udder preparation and post-milking teat disinfection are widely accepted as integral components of a successful mastitis control program. The dairy industry continues to seek efficacious alternatives to iodophore-based post-milking teat disinfectants that have the ability to achieve high efficacy of bactericidal activity while maintaining the integrity of the teat skin condition. This study aims to assess the efficacy of a new Accelerated Hydrogen Peroxide ® (AHP®) teat disinfectant against a commonly used industry competitor.
