DETERMINATION OF DISINVASION EFFICIENCY OF «DEZSAN» PREPARATION AGAINST POULTRY EIMERIA

Introduction. Parasitosis occupies the third place in the world аmong animal diseases. Prevention of helminthoses in industrial poultry farming is based on a complex of measures aimed at effective neutralization of pathogens at different stages of their development. One of the most effective of them is dezinvasion. Dezinvasion in the industrial zones of poultry farms must be subject to premises and their equipment, inventory and all bird care items, walking grounds, poultry droppings.

The goal of the work. Determination of the resistance of the causative agent of poultry eimeriosis to the action of disinfectant "Deszan".

Materials and methods. The diagnosis of eimeriosis was established according to the results of laboratory studies of poultry droppings by the method of Füleborn. As the active substance, the preparation "Deszan" was used in a concentration of 2.0 and 3.0% with exposures of 2, 3 and 4 hours.

Results of research and discussion. When studying the influence of the disinfectant on the eimeria of the Eimeria tenella bird, it was found that when the oocyst is treated with the "Dezsan" preparation at a concentration of 2.0% with 2 hours exposure, the sporulation process stops in the oocysts. The observation was carried out for 5 days, however, no external changes were observed in the eimerias. When oocysts of coccidia were treated with a solution of the preparation "Deszan" at a concentration of 2.0 and 3.0%, during 3 hours of exposure, the sporulation process and compression of the cytoplasm were observed. The exposure of 3–4 hours observed in the field of view of the microscope rupture of shells and fragments of destroyed oocysts of coccidia.

Conclusions and prospects for further research: the disinfection effect of the "Deszan" preparation was established at a concentration of 2.0% with an exposure of 4 hours and 3.0% with an exposure of 3 hours to the ovine’s of the poultry Eimeria tenella. After 2 hours of exposure in oocysts, there was a decrease in sporulation and morphological changes in their cytoplasm.

Keywords: disinfectant "Deszan", disinfection effectiveness, Eimeria tenella, oocysts.
