The purpose this trial was to evaluate the skin toleration of a new experimental acidified sodium chlorite (ASC) barrier teat disinfectant compared to a standard nonbarrier chlorhexidine product with emollients (winter) and a high emollient, iodine barrier (spring) using a split-udder study to focus on the disinfectant effects as well as barrier teat dip issues in winter. Teat skin and end scores were similar between dips as long as the experimental dip was removed with good udder preparation prior to milking. Failure to remove the barrier dip resulted in poorer teat skin and end scores. This points out the necessity for good proper udder preparation premilking when barrier dips are used post milking.
