Epizootic situation for the major parasitosis of farm animals and birds in the Irkutsk region

The development of livestock farming in the Russian Federation, using modern technology and innovation, is an integral part of the state program to improve agricultural efficiency. Increasing the production of milk, meat, and other food products is of strategic importance as a key indicator of the country’s economic growth and the optimization of foreign economic relations. Invasive diseases are one of the constraints on livestock development. They cause significant damage to farms due to the mass mortality of animals during enzootic outbreaks, the stunting of young animals, decreased resistance to infectious and non-infectious diseases, reduced productivity and fertility, deterioration in meat and hide quality, and increased costs for veterinary and sanitary measures. This article presents the results of a study examining the prevalence of parasitic diseases among farm animals and poultry in livestock and poultry farms, as well as enterprises of various types of ownership in the Irkutsk Region. In the period from 2015 to 2023, nematodoses dominated among parasitic diseases of farm animals and birds with an average long-term indicator of extensiveness of invasion: in cattle 12,8±1,11 % (r=0,68; P≤0,001), horses — 22,9±4,05 % (r=—0,18; P≤0,001), small cattle — 17,4±2,86 % (r=0,14; P≤0,05), pigs — 13,5±1,82 % (r=—0,40; P≤0,01) and poultry — 4,3±2,46 % (r=0,34).
