Vaccination of the basic sows by emulsive bivalent inactivated vaccine against parovirus infection of pigs and a reproductive respiratory syndrome of pigs leads to formation of specific antibodies against PRRS which are transferred with colostrum and provide formation of long colostral immunity at pigs. Unitary introduction of vaccine provides formation of protective protection against PRRS at vaccination of remontant young pigs. Titres antihemagglutinating antibodies increases in 10 times. Revaccination of remontant youn pigs does not lead to essential increase in titres of specific antibodies against activator PRRS. The expressed gain of titres of a caption antihemagglutinating antibodies occurs only at those basic sows who had at date of vaccination low (1:32 - 1:64) titres of antibodies. At the sows having titres of antibodies 1:256 and above, stimulations of specific immunity after vaccine introduction do not occur. The received results will allow to improve methods of specific prophylaxis PRRS in pig - breeding farms and will allow to reduce essentially financial expenses for acquisition of biological preparations
