An eight week trial was conducted to evaluate the teat conditioning efficacy of oneexperimental iodine post milking teat dip formula compared to a commercial iodine product.Teat skin and teat end roughnesswere scored for each teat 2X/week. A total of 48 cows were scored during thestudy period, but only 36 cows had full records for analyses. Results showed noconcerning teat skin condition irritation events. There were no differences betweenproducts in teat end condition. However it was observed that teat end conditionworsened over time for both products, most likely as a result ofchanges intemperature during winter.
