Assessment of the effect of the probiotic complex «LiquaFid» on the production performance of sows

The intensity of modern pig farming requires a continuous search for methods to maintain and improve the achieved production indicators and the high health status of animals. The use of various forms of feed additives, including probiotic complexes, can partially solve this problem. Some probiotic strains of bacteria are able to have a preventive effect on the occurrence of pathologies of bacterial or viral origin, they also have a positive effect on the course of metabolic processes of the body. In addition, the use of probiotic complexes in one form or another is less expensive than the use of specific antibacterial or antiviral agents. Our goal was to study the effect of various doses of the probiotic «LiquaFid» on the reproductive ability of sows before farrowing and during lactation. «LiquaFid» is a probiotic complex based on unique spore strains of Bacillus megaterium B –4801 and Bacillus subtilis 1-85 microbes, externally it is a well-soluble powder in water. For the experiment, 4 groups of analogues (n=34) from sows were formed. The experiment was carried out at a full-cycle enterprise engaged in industrial pig farming. The duration of the experience is 33 days. The probiotic complex was given to animals through a water supply system common to breeding stock and young animals. Based on the data obtained from the results of the experiment, it was found that the use of the probiotic «LiquaFid» to uterine livestock immediately before farrowing and during lactation reduced the incidence and severity of the course of obstetric pathologies that arose. Thus, the number of postpartum diseases decreased by 5.89% and 14.71% in the experimental groups, and the incidence of mastitis-metritis-agalactia syndrome, against the background of probiotic use, decreased several times. Due to a decrease in the manifestation of symptoms of dysgalactia, the indicator of suckling of sows has also improved. The production indicators of the obtained young animals in the experimental groups also differed in a positive way. The output of "business" piglets increased by 1.34%, 4.69% and 5.53%, while the live weight of piglets by weaning age also increased.
