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 14^th.
