The present study was conducted to detect the status of anthelmintic resistance for fenbendazole against gastrointestinal nematodes in cattle under field conditions. For this, 10 cattle from village Bhimewala, district Fatehabad and 12 cattle from village Talwandi Rana, district Hisar were selected having eggs per gram (EPG) of faeces >150. The cattle from each district were divided into two group of equal number i.e. T1, T2 of Fatehabad and T3, T4 of Hisar. Animals of T1 and T3 were administered fenbendazole @ 5 mg/kg b. wt., orally while T2 and T4 served as untreated control. Faecal samples were collected on 12th day after treatment from animals of all groups and individual faecal egg counts were determined by modified McMaster technique. Faecal egg count reduction percentage in both group T1 and T3 was 100%. Identification of infective larvae from pre-treatment faecal cultures revealed the predominance of Haemonchus spp. followed by Trichostrongylus spp. and Strongyloides spp. while no larvae were recovered from post treatment in treated groups.
