Different Immune Procedure For White Chicken Ai,ND,IBD The Immune Effect Of Research

With the development of broiler industry factory, disease risk becomes one of the main factors affecting the survival rate, newcastle disease (ND), avian influenza virus (H9subtype) and infectious bursal disease (IBD) and caused the enormous economic losses to the poultry industry, Free immunization is an effective measure to control ND, H9subtype, IBD disease. In this study, in order to select the appropriate vaccine manufacturers in Xinjiang in the region and to develop reasonable and effective immunization program, Select the Xinjiang of TYCOON Group broiler production plant for the study, ues hemagglutination and hemagglutination inhibition assay method, contrast the production of antibodies a matter of time, antibody titers and the rate of decay evaluation of immune effects, to determine the appropriate vaccine, vaccine manufacturers, and appropriate immune time. Detection ND H9subtype of avian influenza H5subtype HI antibody,contrast the production of antibodies a matter of time use hemagglutination and hemagglutination inhibition assay method The immune gel diffusion test (AGP), the detection of different manufacturers bursal disease vaccine,the same day the bursa is positive rate, antibody production and the earliest time, select local bursal disease vaccine. The final optimized for local culture conditions of commercial broiler immune procedure. The experimental results show that the ND+H9oil emulsion inactivated vaccine in7day-old immune Dahua agricultural production, At the same time7day-old immune ha animal studies of H5-ND inactivated vaccine,14days of age the immune Yabeikefashi vesicle vaccine is the best immunization program.
