astreakinchic - 2014-10-10 10:04 AM Okay I was told by one vet that power packing was a waste of money and that moxidectin in quest had no resistance and to use it every 90 days and that would be fine. Another vet recommends fecal checks that are pulled then sent off and spun down. He advised to only worm when needed. A third vet recommended that I scoop a pill bottle size amount of manure and he would centrifuge it and put it on a slide and see parasites present. But he felt everyone needed to power pack in winter and alternate monthly worming with moxidectin, ivermectin, and praziquantel. We got a horse from a rescue situation and he's come a long way as far as body condition. Treated for ulcers but he is just not blooming and it has been a year. Over the course of a year we were at different vets getting different things fixed on him and other horses. When i asked for advice on worming rotations the above was the advice I received. I have been alternating Quest and Quest Plus for a year but i'm wondering if they might not need a power pack this winter to make sure everything is cleaned out. What is everyone's current protocol?
