The general consensus of vets here is now that rotating wormers is NOT adviseable like it used to be, because the parasites will build up tolerances to all of the classes... use one wormer for as long as you get results, until you start having problems... That goes against the conventional "switch wormers" that we heard for years...
Keeping and breeding only the ones that seem to have a higher tolerance is of course the best way to go... but circumstances can negate that in certain times of the year, weather conditions etc...
We do not regularly worm any mature cattle here... they have to look like they need it, thinner, rough hair coat... something.... we do worm anything we buy with not knowing it's previous status... and we do usually worm calves once when weaned and brought to the barn for training to bunk feeding... but again, we do buy some in and do not know what might be coming into the farm... and the stress of weaning will sometimes cause a "bloom" of internal parasites that they might have not had a problem with prior to that....
And ones that are consistent problems... get shipped... no need to keep "hard keepers" .....
