In pasture-raised animals, parasitic infections result in significant financial losses. On the other hand, their prevention and limitation require significant financial resources. Climate change, the existence of causative agents resistant to anthelmintic used for prevention and treatment raise questions requiring focused research under current animal husbandry practices, and premise the frequent presence of gastrointestinal parasites in pasture-raised domestic animals in Europe. The most common nematodes found in sheep in Europe that exhibit anthelmintic resistance are those belonging to the genera Teladorsagia, Haemonchus, and Trichostrongylus. Species from the genus Cooperia and the genus Nematodirus are reported to exhibit resistance less frequently. There is variation in the distribution from west to east and from north to south.
