Abstract:
Ascariasis and Heterophyidae are two species of Helminthiasis which are more common in poultry. There were examined 3 groups of 15 poultry aged 24 weeks of Leghorn and Plymouth Rock ( Plimutroc )races which are bred on the ground. The results of the research show an invasion with helminths of 46,67% in group 1, 60% in group 2, and 26,67% in group 3. When deworming the infested poultry, Brovadasol 5 % proves an efficacy of 100% and Brovalzen shows an effectiveness of 7,5%- 82,7%.
