Results of studying of therapeutic efficiency of developed in the Republic of Belarus biological preparation of trial series against salmonellosis of animals and birds in the conditions of experimental salmonellosis of calves were presented. Research results showed that dualfold application of multivalent antitoxic serum against salmonellosis of calves, piglets and birds which was caused by association of S. Dublin, S. typhimurium, and S. enteritidis was accompanied by activation of humoral immunity. It was revealed in increasing of agglutinating activity of blood serum against S. enteritidis – in 11,5 times, against S. typhimurium – in 10,5 times, and against S. Dublin – in 10,0 times in 6 days after introduction of infection (4-th day after second application serum). Content of Ig M in blood serum calves which were treated with experimental serum increased in 2,0 times on the 6-th day after introduction of infection. Quantity of Ig G increased in 2,6 times by the 6-th day after introduction of infection. All these changes were typical for the clinical recovery of animals. Treatment efficiency of application of the analyzed serum was 75%
