Treats BRD and reduces fever in just one dose.

RESFLOR GOLD combines the powerful antibiotic florfenicol with the fast-acting NSAID flunixin meglumine. It starts controlling the fever associated with BRD in as little as six hours to get cattle back up on their feet.1

The fast-acting, long-lasting BRD treatment.

When BRD takes hold, time is of the essence. That’s why there’s ZUPREVO – the BRD treatment that’s rapidly absorbed in as little as 45 minutes.1 Once in the lungs, it remains there for 28 days.2* Not to mention one low-dose volume of 1 mL/100 lbs. means less handling and more doses per bottle.

Supporting Therapies

Relief is in the palm of your hand.

BANAMINE TRANSDERMAL is the first pour-on approved by the FDA to reduce fever caused by BRD and acute mastitis and pain due to foot rot. It goes to work quickly, and the convenient pour-on administration means less handling, which means less stress on your animals.
