Abstract. The development of industrial meat poultry raising to a certain extent depends on the epizootic situation (concerning IBB), which causes mortality of live-stock up to 50%. One of the ways to achieve epizootic well-being - is to break apart epizootic chain in link "pathogen-susceptible organism" which helps to avoid disorder in poultries which are kept in farms. Recently, doctors of veterinary medicine who provide poultry raising well-being, control the level of protective anti-bodies in order to avoid Hamboro disease in a body of vaccinated poultries. One should take into account the parent’s acquired immune background (so-called maternal antibodies - MAT) in order to reveal protective anti - bodies in poultry’s organism. Monitoring the level of maternal antibodies is one of the most important task, because poultry premature vaccination considering MAT presence in their body may cause the neutralization of the latter vaccine antigen and helps in forming of expected results. Registration of MAT level was conducted by means of various tests, including application of IFA method (immune-ferment analyzes (ELISA), and their coordination with application of alive virus vaccine TAbic MB calculated by Deventer methods based on application of variety coefficient CV% which had been included into Biochek program. The starting point for research work was to reveal the level of MAT concentration against Hamboro diseases in poultry’s body and its conservation needed to determine the optimal conditions for vaccination in poultry raising industry.
Key words : Hamboro disease, specific prophylactic activity, vaccination, anti-bodies, variety coefficient, Deventer's method.
