A Field Trial on the Efficacy of Ivermectin, Albendazole and Coumaphos Against Parasites of Buffaloes

Abstract

Results from identification work yielded six nematodes, one cestode and one trematode, as the helminths accounting for the severe, mixed worm infection in the ranch. The Egg per Gram (E.P.G.) resulted to confirm the ovicidal effect of albendazole and Ivermectin against nematodes, however, the latter have more prolonged action than the former. Gross fecal examination showed that the mentioned drugs had a vermifugal and vermicidal effect on the nematodes. However, Ivermectin lacks this properties against cestodes. Insecticidal activity of Ivermectin was also compared with Coumaphos against lice (Haematopinus spp.). Both displayed the same activity with regards to the ability to get rid of the external parasites. Economic analysis showed that Ivermectin had more expensive than Albendazole and Coumaphos which combined regardless of labor and equipment needed. However, Ivermectin-treated animals showed a higher weight gain than those treated with Albendazole and Coumaphos and control.
