Cloxacillin intramammary infusion is used to treat and prevent mastitis, a bacterial infection of the mammary gland, in livestock like dairy cows. It is effective against infections caused by bacteria such as Staphylococcus aureus, and is administered directly into the teat canal to fight the infection locally. Delivers targeted treatment, with the shortest required dry period – only 28 days – and no milk withhold. So fresh cows can move into the milking string faster.
