(Ralco) Skin Joy Lotion improves udder hygiene and supports skin immunity. Skin Joy contains Synergy Essence, a blend of essential oils including oregano oil for powerful antimicrobial, antifungal, and antioxidant properties. Oregano essential oil has been shown to kill a wide range of pathogenic microorganisms. When dairy cows spend less energy fending off pathogens, they have more energy for milk production. Massage onto each quarter after milking for 2 - 6 days, or as required. Also beneficial for dairy goats.
