ALTERNATIVE METHODS OF PREVENTION OF INFECTIOUS DISEASES OF POULTRY
Abstract
The article presents the results of an analytical study of materials on the features of control of infectious diseases of poultry based on alternative strategies. The poultry sector plays an important role in the agribusiness of various countries of the world, not only as a supplier of meat, but also as an economically profitable segment of the economy. Data published in scientific articles and data presented in the reports of the Food and Agriculture Organization of the United Nations (FAO), the European Food Safety Authority (ESFA) are presented. Modern poultry farming shows increases in the gross production of meat and egg products in many countries of the world. Success is ensured by a comprehensive approach including all aspects of poultry production and welfare (formulation of feeding rations, commercial breeding programs, control of poultry diseases) under different rearing systems. Bacterial infections cause significant damage to commercial poultry farming, which is associated with the restriction of the use of antibacterial drugs in most countries of the world. Monitoring results of pathogens of poultry infectious diseases and effective measures to control poultry bacteriosis in different countries of the world are presented. The most common bacterial and viral pathogens registered in most countries of the world are presented in the materials of the article. The main symptoms that occur in these diseases are also given. The data indicate the growing role of opportunistic microorganisms in the etiology of acute gastrointestinal diseases of poultry, which cause significant economic damage to the industry. Special attention is paid to diseases whose causative agent is common to poultry and humans, since poultry products contaminated with pathogenic and opportunistic microorganisms are a potential source of infections, toxic infections and toxicosis in humans. The interest in bacterioses is explained by the excessively wide geographical spread of the infection, the tendency to stationarity and the intensity of the circulation of pathogens among poultry and humans. The relationship between epizootic and epidemiological processes makes these diseases relevant zoonoses (E.coli, S. Typhimurium, Enterococcus spp., S. aureus, C. jejuni, M. gallisepticum). The complexity of diagnostics and control measures is noted. The main ways of their transmission of pathogens between production sites in production conditions were also analyzed. Alternative strategies for controlling bacterial infections in poultry are also presented.
