Spread of Parasitic Diseases in Domestic Chickens in Azerbaijan

The article describes the prevalence of diseases caused by protozoan intestinal parasites and helminths on poultry farms located in the Sheki and Gakh districts, depending on the age of the bird. During the research, fecal samples were collected from 1-3, 6-9-month-old and older birds and examined using the Darling-Fülleborn method. After the research, the results were analyzed. On poultry farms in the Sheki district, the overall infection rate for all age groups was 37.1% with eimeriosis, 27.6% with ascariasis, 22.9% with heterakiasis and 17.1% with capillariasis. On poultry farms in the Gakh district, the overall infection rate for all age groups was 25.7% with eimeriosis, 18.1% with ascariasis, 17.1% with heterakiasis and 10.5% with capillariasis. The associative infestations identified as a result of surveys have a negative impact on the profitability of poultry enterprises. In addition to treatment, it is necessary to develop and implement comprehensive preventive measures.
