I've been researching how to get rid of parasites in our deer herd. These are some of the parasite that are most common in deer, The roundworm, lungworm, foot worm, brain worm and tapeworm. Roundworms settle in the ligaments of a deer’s joints as well as their hooves. The tapeworm causes malnutrition and can sometimes lead to death. The brain worm is a parasite specific to whitetail deer. If we could eliminate some of these parasites, our deer would have better weights and racks, now to find something that will eliminate some of these parasites, economically. I'll keep looking and let you know what I find. If anyone else knows of a treatment that will work, let us know.
