Characteristics of Russian poultry farms by diseases of different etiology

Industrial poultry farming is accompanied by various infectious and invasive diseases. They have a wide distribution and occupy a large share in the contagious pathology of birds, despite the measures of prevention and control taken by veterinary specialists, which negatively affects the epizootic situation in poultry farming. The article presents materials on retrospective analysis of morbidity of birds with infectious and invasive diseases for 5 years (2018-2022) in Russian poultry farms according to the data of the Ministry of Agriculture of the Russian Federation. During the study period, viral and bacterial diseases (avian influenza, colibacillosis, Newcastle disease, ornithosis, pseudomonosis, tuberculosis, pasteurellosis, salmonellosis, mycoplasmosis, typhus-pullorosis, infectious laryngotracheitis, avian infectious bronchitis, Marek’s disease) and parasitic and fungal diseases (coccidiosis, spirochetosis, sarcoptosis, nematodosis and aspergillosis) were registered. The highest number of sick poultry with viral diseases was recorded in 2021, bacterial diseases in 2018, and parasitic and fungal diseases in 2020, which amounted to 28.289, 15.778 and 0.036%, respectively. In regions with developed poultry farming it is necessary to assess the epizootic situation in order to determine the degree of epizootic risk in specific conditions, the level of potential epidemic threat of the most common zooanthroponotic diseases of birds and timely implement a set of measures to prevent and eliminate diseases in poultry farms.
