Compared the antiseptic effect of conventional protocols with products containing chlorhexidine (pre-dipping) and iodine (post-dipping) with the experimental product (pre-and post-dipping). Conducted clinical daily evaluations of the mammary gland and weekly evaluations as for the health quality, nutritional composition and production of milk in a period of six weeks. Results:the animals showed no clinical mastitis and a similarity was observed in the scores of skin integrity of teats between the groups treated during the experimental period.
