An investigation was conducted to study the efficacy of commonly used chemical as well as few new herbal anthelmintic drugs against gastrointestinal parasite infestation in growing mithuns raised under semi-domesticated management system at the Institutes livestock farm. The drug, Ivermectin showed 99.59% efficacy against Toxocara vitulorum. While,the herbal drugs i.e.. Vet worm and Ficus hirta have shown efficacy of 88% and 84.88% respectively, which was below the recommended standard efficacy of 98%. Nevertheless the Neem (Azadirachta indica) was found to be effective (98.52%) against Toxocara vitulorum infection. The efficacy rate of anthelmintics drugs like Albendazole, Fenbendazole and a combination of Fenbendazole and Praziquantel was 100% and all the treatments were observed to be effective from day 14th.
