there has to be an alterenative to revive. 1 can a day on 5 heifers, way to expensive. i have a custom spray that i have been mixing since march that i am likeing a lot, it keeps ringworm away and if they have it will cure it. it keeps flys away, it helps train and set the hair, and it keeps the hair condtioned, but i still like to use revive every once in a while. what do you think?
