The results of the influence of the biologically active substance “Amylocin” on nonspecific factors of protection of the organism of sows in the second half of gestation and in the first decade after farrowing are presented. It was found that the cellular indications of the natural resistance of the organism throughout the experiment were higher in the experimental group of the lactating sows, that received the biologically active substance, in comparison with the gestating and lactating sows of the control group. Humoral indications of natural resistance of the organism: lysozyme activity of blood serum was higher in the experimental group of the lactating sows in comparison with gestating and lactating sows of the control group by 12.5 and 5.2%; On the contrary, bactericidal activity of blood serum was higher in group of sows during the second half of gestation by 18.9 and 24.9% than in the experimental and control groups of farrowing sows. There were no postpartum complications in the experimental group of sows, the safety of the obtained young growth was higher by 8.6% in comparison with the control group.
