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.
