Worms in Horses – Take a Natural Approach Instead of Blind Deworming
Endoparasites live inside their host and can be classified by location as blood, tissue, or intestinal parasites. Their presence is not a sign of poor care—they are part of the horse’s natural life cycle. However, the decision to administer a dewormer should be carefully considered: although chemical treatments act quickly and eliminate large numbers of worms, they also place heavy stress on the liver, metabolism, and delicate gut flora. The consequences often include overburdened detoxification systems, digestive disturbances, and a weakened immune response. Interestingly, young foals benefit from early contact with internal parasites such as intestinal, blood, or tissue worms. Through their dam’s manure, they take in targeted microbial strains and worm eggs—initiating a vital immune training phase. In fact, regions with high natural parasite exposure report very low levels of autoimmune diseases and allergies, indicating the crucial role these organisms may play in maintaining the body’s internal balance.
