Anthelmintic resistance (AR) against commonly used anthelmintics (albendazole, fenbendazole and closantel) was studied in naturally occurring gastrointestinal (GI) nematodes in adult goats of Goat Research Station, Assam Agricultural University, Burnihat.  After qualitative and quantitative screening of faeces of 112 goats (44 local, 24 crossbred and 44 Beetal goats) having egg per gram of faeces (EPG) >500 were randomly selected and divided into 4 equal groups. Albendazole @ 5 mg/kg body weight, fenbendazole @ 7 mg/kg body weight and closantel @ 10 mg/kg body weight orally were given to local, crossbred and Beetal treated groups, respectively. Through the Faecal egg count reduction test (FECRT), the efficacy of albendazole in the case of local, crossbred and Beetal goat was found to be 78.22, 76.85 and 61.86 per cent, respectively. In the case of fenbendazole for local, crossbred and Beetal goat efficacy was 73.27, 78.70 and 60.59 per cent, respectively. On the other hand, in the same breed sequence, the efficacy for closantel was 92.34, 79.63 and 75.85 per cent, respectively.
