I don't use a wormer on my cows. A couple years ago my vet swore I just had to use Eprinex. We sampled the manure of 20% of my herd at random and sent them in. Now, you can have a certain number of creepy crawlies in there and be OK. My cows had zero. Not one found. So I continue to not use anything.
