Sheep and goat parasites

Many internal parasites commonly affect sheep and goats. They fall into four categories: nematodes (roundworms), cestodes (tapeworms), trematodes (flukes), and protozoa (coccidia). The parasites that cause the most problems on a farm or to an animal depend upon the geographic location of the farm, weather conditions, and season. On this page, links are arranged alphabetically according to worm species or subject category: sheep and goat parasites, liver flukes, lungworms, meningeal worm, roundworms, and tapeworms.
