To increase the possibility of choice anthelminth drugs for geese the efficacy of anthelmintic preparates used in fossorial birds to control geese helminthiases was examined. The examinations were performed on 2410 geese from the reproductive herds in 8 experimental groups. The intensity and extensiveness of parasitic invasion was evaluated by the Mc Master method of the examinations of feces. The birds were treated in autumn (November-December), e.g. one month before the predicted egg laying period. The following drugs were applied: group I—III, Bantminth 50 and 25 mg/kg of body weight once, 12.5 mg/kg twice, every day; group IV, Systamex 40 mg/kg; group V, Fenbesan 5 mg/kg, twice every day; group VI, Ivomec, injection subcutaneous 200 (µg/kg, group VII, Nilverm 50 mg/kg; Levamisole 15 mg/kg. The highest efficacy (100%) in the control of amidostomosis revealed Ivomec used in subcutaneous injection, then Banminth used as food additive: 95.3% at a dose of 50 mg/kg, 94.6% at a dose of 25 mg/kg, Systamex 91.9%, Banminth 88.4% used at a dose 12.5 mg/kg twice, Levamisole 86.7%, Nilverm 86.3% and Fenbesan 80.0%.
