Ist die FAMACHA©-Eye-Colour-Karte zur klinischen Diagnose von Haemonchus contortus – Befall bei Schafen und Ziegen in Norddeutschland geeignet?

Summary

In sheep and goats the most pathogenous worm is the bloodsucking Barber’s pole worm Haemonchus contortus. Studies in South Africa confirmed the FAMACHA-Test to be a useful tool for identifying anaemic animals. Apart from the reduction of anthelmintic drugs, the targeted, selective treatment of single animals may delay the development of anthelmintic-resistant worms. Three field studies, carried out in Northern Germany in consecutive years, showed that at a comparatively low infestation of H.contortus, the FAMACHA©-Eye-Colour-Test had not enough power for detecting all animals with the highest worm egg output (KOOPMANN et al. 2006). If the repeated examination during the pasture period by the FAMACHA©-Eye-Colour-Score is possible, it could find the very pale animals in need to be treated.
