Evaluation of Most Suitable and Effective Anthelminthics for Internal Parasites of the Goat

The study was aimed to determine the efficacy of albendazole and mebendazole against gastro-intestinal nematodes in goats in Therrappane goat farm in North Central province. Thirty animals were used for the study. Albendazole and mebendazole were given orally to animals at a dosage of 15 mg,kg body weight. Fecal samples were collected at 0 and 7 days after treatment and were examined for worm eggs using simple floatation method. When available, egg-containing fecal samples were counted for the number of eggs per gram (EPG) of feces using McMaster technique. From fecal examination, egg types present in dung samples in normal goats were strongyle, tapeworms, strongyloide, and tricuris. The highest percentage of egg type present in fecal matter was strongyle (86%) egg type. The 89% of nematode parasite infection and 11% of tapewormsʹ parasite infection were examined in the farm. There were significant difference (p<0.05) in strongyle egg type, strongyloid egg type, tricuris egg type and tapeworm egg type between control and albendazole treated group and also there is a significant difference (p<0.05) in tapeworm egg type between control & mebendazole treated group. The efficacy of albendazole was 69.95% for the nematode and 60.29% for the tape worms. The mebendazole was more effective for the tape worms (65.51%). The treated albendazole group was 100% effective for the strongyloid egg type, tricuris egg type and mebendazole was 100% effective for the tricuris egg type. Results showed high efficacy of albendazole in controling of gastro-intestinal nematodes of goats
