Morphological and structural changes in bone marrow of piglets which were immunized with produced in the Republic of Belarus SPS vaccine (against salmonellosis (Salmonella), pasteurellosis (Pasteurella) and streptococcus) in combination with immunostimulants and without them were analyzed in the conditions of the Republic of Belarus. Piglets of the first group were vaccinated against salmonellosis, pasteurellosis and streptoccocusis by SPS vaccine. Piglets of the second group were vaccinated by SPS vaccine with vitamin C. Piglets of the third group were vaccinated by SPS vaccine with immunotstimulant sodium thiosulphate. The fourth (control) group of animals was administrated with normal saline. Animals were immunized twice, intramuscularly with 7 day interval in dose of 4 ml (primary), and 5 ml (secondary). Vitamin С was administrated in dose of 0,05g per head. Sodium thiosulfate was administrated in combination with the vaccine in 30% concentration. Alongside with myelogram there were derived formulas of different cell groups of bone marrow: leucoerythroblastic index; intramedullary index of neutrophil maturity; intramedullary index of eosinophile maturity. Detailed myelogram of piglets on the 14-th day after the second immunization was presented. Research results showed that in all groups of vaccinated animals there was noted the activation of myeloblastic hematogenesis and decreasing of erythropoeisis. Piglet immunization was accompanied by strengthening of myeloblastic hematogenesis, increased number of lymphocytes and plasma cells in bone marrow
