Anthelmintic efficacy of ivermectin against Syngamus trachea and Capillaria spp. in pheasant.

Ivermectin (IVM) was perorally administered in dosage schemes 1 x 0.8 mg/kg of body weight (b.w.), 1 x 1.6 mg/kg h.w., 3 x 0.8 mg/kg b.w., and 3 x 1.6 mg/kg b.w. to pheasants infected by Syngamus trachea and Capillaria spp. The samples of faeces were coprologically examined. The clinical state of pheasant was controlled. In all of the used therapeutical schemes the helminthostatic or partially helminthocide effect against adults of worms was reached. The clinical signs of helmithoses were reduced only. IVM in tested doses is not possible to recommend as an effective drug of pheasant syngamosis and capillariosis.
