Цестодози курей в умовах особистих селянських господарств південно-східного регіону України

Abstract

Райєтиноз є поширеною цестодозною інвазією серед курей особистих селянських господарств південно-східного регіону України. Екстенсивність інвазування курей у Дніпропетровській області становила 16,3-18,9 %, у Херсонській – 11,6-13,0 %. Найменший рівень інвазованості курей райєтинами зареєстрований у східних та північних областях України (Харківська – 7,3-11,1 % та Сумська 6,4-8,0 %).

The industrial poultry management system in enclosed spaces (in cages or on the floor), subject to veterinary and sanitary regulations, largely solves the problem of hens invasions. However, poultry farming on smallholder farms and private farms, with traditional day-care facilities, is often accompanied by a variety of invasive pathologies, including biohelminthoses such as rayetinosis. Object of research: chickens of different ages and breeds of private farms of the south-eastern region of Ukraine. Purpose of the work: to study the epizootic situation on intestinal cеstodoses of hens in the conditions of private farms of the East and South of Ukraine. Epizootic studies of the situation on cеstodoses were conducted in private farms of Kharkіv, Sumy, Donetsk, Dnіpropetrovsk and Kherson regions. Generally accepted epizootological, clinical and parasitological and special coproscopic methods of research were conducted. The material for the life-long study was selected by random sampling during defecation and from the floor. Feces (litter) was examined by helminthoovoscopy (by Fulleborn and Kotelnikov-Khrenov methods) to identify eggs of pathogens and by helminthoscopy to find the parts of the cеstodes in their natural deposition and after diagnostic deworming. Postmortem helminthic autopsy of hens intestines was performed according to K.I. Skryabin. As a result of researches it is established that rayetinosis is a widespread cestodosis invasion among hens of private farms of the south-east region of Ukraine. Depending on the territorial location and natural-climatic zone, rayetinosis is more often spread in southern regions. The intensity of invasion of hens in Dnepropetrovsk region was 16,3-18,9 %, in Kherson region – 11,6-13,0 %. The lowest level of hens invasions by the cestodes of the genus Raillietina was registered in the eastern and northern regions of Ukraine (Kharkiv – 7,3-11,1 % and Sumy – 6,4-8,0 %).
