Efficacy of albendazole and levamisole at different dose levels against Ascaridia galli.

Different dose rates of albendazole (3.5 mg kg⁻¹, 7 mg kg⁻¹, b.w.) and levamisole (10 mg kg⁻¹, 20 mg kg⁻¹, 40 mg kg⁻¹, b.w.) were evaluated against experimental infection of Ascaridia galli in poultry. Albendazole @ 14 mg kg⁻¹ b.w. was found 100% effective in reducing the EPG and 100% effective in reducing the post-mortem worm count, respectively. Levamisole @ 10 mg kg⁻¹, 20 mg kg⁻¹, 40 mg kg⁻¹ b.w. was found 100% effective in reducing the EPG and removing the matured worms at all three dose rates.
