Abstract:
Anthelmintic efficacy of levamisole, albendazole, ivermectin and morantel tartrate was evaluated in 75 sheep naturally parasitized with Haemonchus, Trichostrongylus, Oesophagostomum and Ostertagia spp. Results revealed that levamisole, albendazole, ivermectin and morantel tartrate were lOO, 98.82, 97.02 and 76.50 per cent effective, respectively in reducing the eggs per gram of faeces. The animals treated with these anthelmintics gained more weight compared with untreated animals. It was recommended that levamisole be used as a drug of choice in local conditions against nematodes of sheep followed by albendazole and ivermectin in the order of their efficacy.
