Udder care and hygiene in cows is important in  milking, aiding uninterrupted and untainted milk production, and preventing  mastitis. Products exist to soothe the chapped skin of the udder. This helps prevent bacterial infection, and reduces irritation during milking by the cups, and so the cow is less likely to kick the cups off. It has been shown that incorporating nutritional supplements into diet, including vitamin E, is an additional method of improving udder health and reducing infection. ^[1]
