Annotatsiya
Abstract“Samarkand-Parranda” JV analyzed the frequency and effectiveness of scheduled vaccinations from 1980 to 2012 and noted that the type and number of scheduled vaccinations have doubled. JV "Ohalik-Lomannparranda" analyzed the frequency and intensity of vaccinations against Newcastle disease in 1997–1998. An increase in the number and type of vaccinations has been found to cause immunosuppressive syndrome. Immunosuppression was primarily determined by the suppression of postvaccinal immunity generated against Newcastle disease and infectious bronchitis. Immunosuppression has been reported to increase the risk of conditionally pathogenic infections. Immunosuppression has also been found to be influenced by the large population density of poultry farms and the narrow distances between poultry houses and farms. It is recommended to use the immunosuppression phenomenon and give priority to small business to prevent immunosuppressive syndrome.
