[Use of mebendazole for helminthiases in chickens and geese].

103 chickens experimentally infected with Capillaria obsignata were treated with Mebendazol at a dose of 30 mg/kg body-weight daily for 3 consecutive days. The effectiveness of the drug on the 4th stage larvae as well as immature and mature 5th stage forms were 92,5%, 98% and 98,8% respectively. In another experiment to 32 chickens experimentally infected with Syngamus trachea Mebendazol was given at 40 mg/kg body-weight on 3 successive days. Mebendazol removed the immature and mature gape worms completely. The anthelmintic effect of Mebendazol was also tested at 18 geese naturally infected with Amidostomum anseris, Trichostrongylus tenuis, Capillaria anatis, Hymenolepis lanceolata and Hymenolepis setigera. The treatment removed nematode-infection completely at a dose of 10 mg/kg body-weight and cestode-infection at a dose of 30 mg/kg body-weight when given daily for 3 consecutive days. Two groups of geese, 20 in each group, were treated against Hymenolepis-infection using Mebendazol in food for 6 consecutive days. It was found that Mebendazol when given at a dose of 10 mg/kg body-weight for 6 days removed the infection partly, whereas 30 mg/kg body-weight eliminated the whole worm burden.
