Comparative evaluation of the influence of cell-free probiotic preparation Laktimet and cellular probiotic Bifilak on productivity, livability, nonspecific response of suckling piglets in the early extrauterine life was realized in the conditions of the Republic of Belarus.Application of both probiotics increased the productivity of suckling pigs, stimulated the processes of metabolism and natural protection of organism in the early postnatal period in the conditions of specialized pig breeding complexes. Research results showed, that application of brand new cell-free probiotic Laktimet exercised higher influence on suckling pigs. Application of Laktimet made it possibler to increase piglets body weight gain on 7,8%; piglet livability - on 6,7%; and application cellular probiotic preparation Bifilak - on 5,4% and 3,3%, respectively. The same tendency was noted during the analysis of indexes of cellular factors of organism protection. Bactericidal activity of blood serum of experimental animals changed both in connection with age, and under influence of probiotic preparations. During all studied periods the bactericidal activity of blood serum was authentically (P less than 0,05) above in experimental groups in comparison with a control group. At 20-days old piglets there was stated the strengthening of bactericidal activity of blood serum. Throughout all period of experiment the superiority of trial animals over control on indicators of lysozyme activity of blood serum was observed
