Abstract
Turkey breeding in the Russian Federation has a positive development trend, this is due to many useful qualities of meat. In addition to the positive aspects of the development of the turkey breeding industry, there are also negative ones, for example, as poultry farms in the turkey breeding sector develop and increase, the risks of infectious diseases increase, the most relevant for industrial turkey breeding is the prevention of dangerous diseases (OIE list) - Newcastle disease (NB), avian influenza (AI) and economically significant diseases of turkeys - hemorrhagic enteritis of turkeys (HE), infectious avian encephalomyelitis (AE), respiratory mycoplasmosis and mycoplasmic synovitis caused by Mycoplasma gallisepticum (MG) and Mycoplasma meleagridis (MM). The most common and economically dangerous disease is hemorrhagic enteritis of turkeys, unfortunately in the Russian Federation this disease is poorly studied. Therefore, it is necessary to direct research to the study of the biological properties of the virus, which will help to create diagnostic kits and means of specific prevention. That is why the purpose of our work is to study the biological properties of the HE virus. This set of studies includes: studying the concentration of the virus in target organs, macroscopic changes in organs, maternal immunity using the example of the half-life of antibodies to hemorrhagic enteritis. As a result of the conducted studies, data on macro and microscopic changes were obtained, the concentration of the virus was determined on various days after infection with RDP, and the halflife of maternal antibodies was determined. All these results will form the basis for the development of diagnostic tools and specific prevention in the future.
