Level invasiveness helminths of chickens in the area of “Aran” Azerbaijan

Abstract

In private poultry farms of the republic, the “Aran” region, with a high average annual air temperature, studies were conducted to identify bird invasion by helminths by age groups in seasonal dynamics. Autopsy of carcases and coprological studies conducted among birds in different age groups showed that the invasion of birds ascaridia, heterakis, syngamus, capillaria and raitellina 3-6-months of age compared with other age groups is higher. However, the intensity of ascaridia in 6-8-monthly birds is higher. Study to establish the invasion of birds by the seasons of the year, it was found that the intensity of invasion in all species reaches the highest limit in the summer period of the year, which is due to the intensive development of pathogens with increasing ambient temperature. In winter, when the temperature is low, the degree of infection of birds with helminthiases decreases. During this period of the year, a significant decrease in the spread of invasions is observed in poultry farms and the intensity drops to a minimum. Thus, the infection of birds with ascariasis, heterciasis, syngamosis, capillariasis, and raytinotomy is observed throughout the year. The obtained data will make it possible to develop rational schemes for the prevention and treatment of bird helminth infections in private households, and to reduce the environmental contamination by helminths.
