Efficacy of fenbendazole, levamisole and ivermectin against gastrointestinal nematodes in Jamunapari goats.

Efficacy of fenbendazole, levamisole and ivermectin was checked in comparison to untreated controls in twenty Jamunapari goats, naturally infected with gastrointestinal nematode parasites. Faecal examination at day 0 revealed an egg per gram of 930 ± 175.1, 1350 ± 421.1, 1060 ± 224.9 and 800 ± 279.7 in group A, B, C and D, respectively having five animals each. The results of larval culture examination revealed the presence of Haemonchus, Trichostrongylus, Oesophagostomum, Bunostomum and Strongyloides spp. in these animals. Faecal egg counts of the animals treated with fenbendazole (group A), levamisole (group B) and ivermectin (group C) were reduced by 23.66, 63.70 and 98.11%, respectively on day 14 post-treatment.
