Grazing parasitism of dairy heifers: prospective use of serum pepsinogen and targeted selective treatment

Original titleParasitisme du pâturage des génisses laitières: prospective sur l’emploi du pepsinogène sérique et traitement ciblé sélectif
Abstract

Heifers are parasitised by gastrointestinal nematodes as soon as they are turned out to grass, with consequences for their health and development. The use of antiparasitics limits these negative effects but slows down the development of a solid and durable immunity, selects resistant parasites and has environmental consequences. Targeted selective treatment is a rational and optimised anthelmintic use. The end of the first grazing season is a key time to apply it. The first action of the project is to determine a validity period for serum pepsinogen. To do this, a better knowledge of the kinetics of this commonly used indicator is essential. The second action will then focus on assessing the relevance of individual indicators for selecting which heifers require treatment. The third action will look at the post-treatment effect, and the last action will concern the dissemination of the results via a wide range of media.
