Distribution of nematodoses of poultry in farms of Poltava region

Abstract

The task of meeting the needs of the population with high-quality poultry products is to create a stable veterinary welfare in farms of various forms of ownership by in-depth study of the epizootic situation of nematodoses, which are registered in poultry. This will effectively develop and implement a system of treatment and prevention measures and reduce the incidence and death of poultry, especially from mixed helminthiasis. The aim of the work was to study the species composition, distribution and features of the course of nematodoses of the digestive tract in poultry in the farms of Poltava region. A total of 241 coprooscopic studies of chickens and 186 – geese were performed. Parasitological studies have shown that nematodoses of the digestive tract among domestic geese and chickens in farms of Poltava region are very common invasive diseases, where the extensiveness of invasion ranges from 16.59 to 74.69 %. In the studied chickens, pathogens of heterakosis (EI – 74.69 %), ascaridiosis (41.49 %), capillariosis (31.54 %), trihostrongilosis (16.59 %) were detected. Among the studied geese, pathogens of heterakosis (41.94 %), amidostomosis (27.42 %), capillariosis (25.81 %) and trihostrongilosis (16.67 %) were found. It is proved that nematodoses of the digestive tract mainly occur in the form of polyinvasions. In 67.22 % of patients with nematodoses of chickens, the simultaneous course of several parasitic pathogens was established, in geese this figure was 57.69 %. Monoinvasions were detected in 32.78 and 42.31 % of patients with nematodoses of chickens and geese, respectively. Out of the polyinvasions of chickens, two-component ones predominated, where heterakosis-capillariosic and ascaridiosis-heterakosic were most often diagnosed (51.24 and 33.06 % of patients with polyinvasions). Ascaridiosis-trihostrongilosis-capillariosic (9.92 %) and heterakosis-trihostrongilosis-capillariosic (5.78 %) invasions were less frequent. Among geese, heterakosis-capillariosic (40 % of patients with polyinvasions) and amidostomosis-capillariosic (28.89 %) invasions dominated among polyinvasions. A smaller percentage were heterakosis-amidostomosis-capillariosic (20 %) and amidostomosis-trihostrongilosis (11.11 %) invasions. Prospects for further research are to establish the effectiveness of modern anthelmintics in polyinvasions of geese and chickens.
