%A Veronika Maurer %A Zivile Amsler %A Felix Heckendorn %A Erika Perler %T Development of prevention and treatment strategies for parasites in poultry %X Parasitic infections are likely to be more important in organic and other free-range hens than in birds kept indoors. Several workpackages of QLIF aim at improving prevention and therapy of helminth (Ascaridia galli and Heterakis gallinarum) and arthropod (Dermanyssus gallinae) parasites of laying hens. This paper is a summary of the work undertaken in the first 3 years of QLIF. %D 2007 %K poultry, parasite control, Ascaridia galli, Dermanyssus gallinae, Veterin?rparasitologie, Endoparasitenkontrolle, Prophylaxe QLIF, Phytotherapie QLIF, Ektoparasitenkontrolle, Dermanyssus QLIF, %L orgprints10267
