Description
Summary:The targeted selective treatments (TST) aim at reducing the number of anthelmintic treatments but also to maintain productivity of animals. The aim of this work was to assess the validity of pathophysiological indicators for detecting individually ewes in need for treatments in two regions of Morocco with different management and climatic environment (Chaouia plain-seven farms, and Middle-Atlas-three farms). Although resistance to benzimidazoles was already present the same drug was used for TST. The indicators tested were: FAMACHA© (associated with anaemia), DISCO (diarrhoea score), and BODCON (body condition score). Only FAMACHA© and DISCO indicators were well correlated to the EPGs. DISCO only did permit a substantial reduction (up to 85%) of the number of treatment and EPG (nematode eggs per gramme) remained low on average (less than 160).
