actually they have disproved that theory,now they say ivomec does no more damage to the dung beetles than cydectin. the guy sho used to take care of missouri's university cattle decided worming was not worth it & quit years ago. he claimed they would always be a few cattle in the herd that would show signs that worms were bothering them, but the rest showed no signs & it was better to sell the ones that could not handle the worms on their own. & keep cattle that developed good immunity to worms
