Abstract:
Anthelmintic resistance (AR) against commonly used anthelmintics (Albendazole, Fenbendazole and Closantel) was studied in naturally occurring gastrointestinal (GI) nematodes in adult goat of Halogaon area of Kamrup district of Assam. After qualitative and quantitative screening of faeces of 44 Assam hill goats having egg per gram of faeces (EPG) > 500 were randomly selected and divided into 4 equal groups (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. The arithmetic faecal egg count reduction (FECR) for albendazole, fenbendazole and closantel were 96.36%, 89.09% and 100%, respectively. Therefore, the study revealed confirmed resistance to fenbendazole against gastrointestinal nematodes of goat.
