A study was conducted to determine the efficacy of a benzimidazole anthelmintic (fenbendazole) on horse farms in Slovakia. Nine stud farms with a total number of 80 horses were selected for the faecal egg count reduction (FECR) test. Resistance was assumed if egg count reduction was less than 90%. A low level of benzimidazole resistance was found on three farms (84.4–89.0%). On the remaining farms the results of the FECR test indicated substantial reduction in faecal egg output a�er treatment (92.5–99.4%). Larval identification before treatment revealed Cyathostominea larvae as being predominant.
