Mastitis protection with the lowest level of endotoxin on the market.1
BOVILIS J-5 is a Gram-negative core-antigen vaccine that reduces both the frequency and severity of coliform mastitis caused by Escherichia coli. Of competitive vaccines, BOVILIS J-5 contains the lowest level of endotoxins – 15 times lower than the U.S. Pharmacopeia recommendation.1


The dry cow mastitis treatment trusted for more than four decades.
ORBENIN-DC delivers a targeted treatment of Gram-positive bacteria to treat mastitis at dry-off. It has the shortest dry period of just 28 days so fresh cows can move into the milking string faster. And a short tip reduces the risk of new infection at administration by 50%.3
