Probiotic supplement in pregnant sows in the conditions of industrial pig breeding

The industrial form of pig rearing and breeding implies a significant degree of intensification of all technological processes to obtain the greatest benefit with the lowest economic costs. All this is aimed at solving issues of food supply, import substitution in compliance with the rules of veterinary and sanitary safety. However, during the transition of pig breeding to intensive industrial technology, there is an incomplete compliance of the physiological needs of animals with technological requirements, as a result of which a potential decrease in productivity, resistance, and the development of internal diseases is possible. The main organ involved in all metabolic processes of metabolism is the liver. The purpose of the presented study was to evaluate the effect of the feed biologically active additive "Vetlaktoflor" on the biochemical parameters of the blood in pregnant sows. To study the effect of the "Vetlaktoflor", 4 groups of sows were formed. One control group without the use of the agent and 3 experimental groups where the agent was used according to the following scheme: experimental group -2 - animals were given the active additive "Vetlaktoflor" 2 weeks before farrowing, experimental group-3 - animals were given the active additive "Vetlaktoflor" 2 months before farrowing, experimental group-4 - animals received the biologically active additive "Vetlaktoflor" twice during pregnancy: 2 months and 2 weeks before farrowing.As a result of the use of a biologically active additive, the stabilization of the activity of serum enzymes AlAT and AsAT was noted. In the experimental groups, the activity level of these enzymes was lower by 43.93-67.32% and 30.91-52.56%, respectively. Thus, the probiotic "Vetlaktoflor" is effective when used during pregnancy, reducing the degree of endogenous load on the body of pregnant sows, as well as keeping the level of these enzymes within the reference values, which indicates the stabilization of the state of hepatocellular metabolism.
