I have some 60-90 day old calves still on momma. Decent grass hay, protein/bovatec/mineral tubs. I don't normally worm calves till weaning but they're looking a little pottier and rattier than I like. Any suggestions on a multipurpose wormer for that situation? The cows were all wormed this fall with ivomec. Probably need something injectable for the calves given the weather.
