Anthelmintic resistance (AR) to commonly used anthelmintics (Albendazole, Fenbendazole, and Closantel) in naturally occurring gastrointestinal (GI) nematodes in adult goats from the Guwahati plain and hilly areas of Assam was investigated. After the qualitative and quantitative screening of the faeces of 88 Assam hill goats (local), 44 from Guwahati plain and 44 from Guwahati hilly area were randomly selected and divided into four equal groups, with egg per gram of faeces (EPG) >500 (three treated and one infected control group). Albendazole @ 5 mg/kg body weight, fenbendazole @ 7 mg/kg body weight and closantel @ 10 mg/kg body weight orally were given to the treated groups of both the study areas. The arithmetic faecal egg count reduction (FECR) for albendazole, fenbendazole and closantel were 82.07%, 82.07% and 95.11%, respectively at Guwahati plain area while at Guwahati hilly area the FECR percentage for albendazole, fenbendazole and closantel were 86.93, 79.74 and 97.39 per cent, respectively. The present study revealed confirmed resistance to albendazole and fenbendazole in nematode parasites of goat in both the localities of Guwahati.
