Abstract

Efficacy of four commonly used anthelmintics have been evaluated against naturally occurring gastrointestinal nematodes in goats following the method of faecal egg count reduction test (FECRT) in the present study. Fifty goats in the age group of 1 to 2 years old and of either sex, having infection with strongyle group of nematodes were selected in the sheep and goat farm under project ‘Biotech Kisan Hub”, West Bengal University of Animal and Fishery sciences and the goats were equally divided into five groups; group I (infected control), group II (albendazole treated), group III (fenbendazole treated), group IV (ivermectin treated) and group V (levamisole treated). Faecal egg count (FEC) in terms of eggs per gram of faeces (EPG) were estimated in all the experimental goats (n = 50) on 0-day post treatment (0 DPT) and again on 10 DPT. Efficacy of albendazole, fenbendazole, ivermectin and levamisole were 78.15%, 80.24%, 86.38% and 95.46%, respectively. Comparatively less efficacy of albendazole and fenbendazole indicated the emergence of anthelmintic resistance and lower efficacy of ivermectin might be due selection of resistant worms. Efficacy of levamisole was comparatively higher and it can be used strategically to control GI helminth parasites of goats in that farm.
