For the development of various breeds of geese (Anser) health improvement from intestinal parasites in the conditions of the Republic of Belarus there were realized the following measures: investigation of entozoic parasites fauna of domestic geese; determination of age - specific and seasonal dynamics of entozoic parasites; study of pathogenesis and clinical aspects of eimeriosis; determination of life cycle of geese intestinal parasites in natural environment; development of the complex of biotechnological measures on prophylaxis of geese eimeriosis. In course of investigation there were revealed the following parasitocoenoses: 1. in domestic geese: Tyzzeria anseris, Eimeria parvula Trichomonas anseris E. anseris, E. parvula, Amidostomum anseris. Capillaria anseris, Ascaridia anseris; Eimeria truncata; Echinostoma revolutum, Notocotylus attenuatus; Eimeria anseris, Eimeria stigmosa; 2. in gray geese: Echinostoma revolutum, Notocotylus attenuatus; Eimeria anseris Kotlan. In some cases in young stock (up to 4 months old) there was reveled Isospora Lacasei. Investigation of 978 domestic geese on farms and private plots revealed that 39% of them were infested. The following invasions were stated: eimerias species (15%), amidostomum (3%) and polyinvasion. Research of the life cycle of and pathogenicity of Eimeria stignosa, Eimeri nocens and sporulation of oocyst were presented. Results of microscopic examination of histological samples were stared and biological measures of eimeriosis prevention were analysed
