The maximal affection extensity with helminthic-protozoal invasion of chickens and quails as well as the clinical signs have been elucidated. The effects of helminths in association with eimeria on the morphological and biochemical blood indices have been determined. It has been studied that the dominating agent in chickens is Ascaridia galli. The method of treatment under the invasion diseases of animals has been suggested. A high treatment efficacy (100 %) of Brovanol D, Brovalevamizol 8 %, Brovermaktin granulate in combination with an extract of Waxworm 25 %, and brotheradasol plus with austerity has been proved. The antihelmintics with different active substances have been tested. The final hematological indices indicate at the positive effect of chickens and quails treatment. The disinvasive efficiency of chemical control agents like Brovadez-20, Crystal-1000 and Neochlor against the helminth eggs and oocyst eimeria of the intestinal invasions of chickens and quails has been determined.
