Protein metabolism activation in pig industry in pregnant sows

Abstract

In the agro-industrial complex livestock sector the tendency to reduce the use of antibacterial agents in production is increasing. In this regard, the use of probiotics is gaining popularity around the world. Being antagonists of pathogenic and opportunistic intestinal microorganisms, suppressing their growth and reproduction, as well as creating favorable conditions for the obligate microflora of the gastrointestinal tract, probiotics are becoming increasingly important. The feed biologically active additive "Vetlaktoflor" belongs to the preparations of this group.The purpose of the presented work was to study the effect of the feed biologically active additive "Vetlaktoflor" on the biochemical parameters of the blood of pregnant pigs. To study the effect of the drug, 4 groups of sows were formed. One control group without the use of the drug and 3 experimental groups where the drug 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, stable values of total protein and its fractions, urea, creatinine were noted. At the same time, the increase in total protein values increased in the range from 16.12% to 17.01%, albumin values increased to 62.10%, globulin values increased to 34.96%. Indicators of urea and creatinine with a slight increase remained within the reference values. Thus, the probiotic "Vetlaktoflor" is effective when used during pregnancy, stimulating the processes of protein metabolism, thereby ensuring a stable course of pregnancy. With intensive nitrogen metabolism characteristic of pregnancy, this biologically active additive ensures that urea and creatinine indicators are found within the average reference values.
