Abstract:
In the present study, 20 sheep and 20 goats from University Sheep and Goat Breeding Farm which were naturally infected with gastro-intestinal (GI) nematodes and having at least 150 eggs per gram (EPG) counts were selected and grouped into four groups i.e. T1, T2, T3 and T4 of 10 animals each. Group T1 of sheep and T2 of goats were treated with fenbendazole @ 5 mg/kg b.wt and 10 mg/kg b.wt orally, respectively while, Group T3 of sheep and T4 of goats served as untreated control. To assess the prevalence of anthelmintic resistance Faecal Egg Count Reduction Test was used (FECRT). The percentage reduction in faecal egg counts by fenbendazole on University Sheep and goat Breeding Farms were 62.17 and 48.17%, respectively. This indicated moderate to severe fenbendazole resistance in sheep and goats of these farms. Coprocultures from post-treatment faecal cultures revealed the predominance of Haemonchus contortus larvae.
