Stromberg says studies show benefits of deworming weaning-age calves at least two weeks before vaccinating, thus allowing them to mount a better vaccine response. In some areas, anthelmintics may need to include fluke control ingredients; whereas in other areas, these would be unnecessary. Tom Yazwinski, University of Arkansas parasitologist, recommends deworming cows about the time of calving – when they are immunologically compromised. There are some situations where it’s useful in stocker calves – where there’s drug resistance to other dewormers,” Craig explains.
