The influence of the use of biologically active feed additive "Vetlaktoflor" to pregnant pigs on the performance of farrowing and the quality of the resulting young

Abstract

Against the background of moving away from the use of antibacterial drugs in animal husbandry, preparations containing probiotics are becoming increasingly important. Such drugs have the ability to suppress and neutralize the action of conditionally pathogenic intestinal microflora, while maintaining the obligate microflora of the gastrointestinal tract of animals of different age groups. Feed biologically active additive "Vetlaktoflor" is one of the preparations in this direction. The aim of the work was to study the effect of the use of the Vetlaktoflor probiotic supplement, which is recommended for use in young animals, on the quality of the resulting young animals and their productive indicators during pregnancy. In the course of the research, 4 experimental groups of pregnant sows were formed. The control group without the use of the drug and 3 experimental groups, where the drug was used according to the following scheme: 2nd experimental group - the active additive "Vetlaktoflor" was used in animals 2 weeks before farrowing, 3rd experimental group - the active additive "Vetlaktoflor" was used in animals 2 months before farrowing , 4 experimental group - animals received the biologically active additive "Vetlaktoflor" twice during gestation: 2 months before farrowing and 2 weeks before farrowing. The probiotic was administered orally individually, at a dose of 8 ml per head, once a day, for 2 weeks. At the time of farrowing, the data on the number of stillborn and culled piglets were recorded, the mortality of piglets and the number of diarrhea were recorded within 2 decades after birth. The use of the feed biologically active additive "Vetlaktoflor" at the time of farrowing showed a decrease in the number of stillborn and culled piglets in the control groups. And if in the control group the number of stillborns was 7.4%, then in the experimental groups the highest figure was 2.8%, as well as the number of culled livestock in the control group was 11.7%, while in the experimental groups this indicator in its highest value was 6.6%, which indicates a higher farrowing rate. The mortality rate of young animals over two decades in the experimental groups had the highest rate of 2.8%, while in the control group it was 11.4%. At the same time, the number of cases of disorders of the gastrointestinal tract of young animals in the experimental groups had the highest value of 8.92%, while in the control group it was 24.11%. The use of the probiotic "Vetlaktoflor" is effective in pig pregnancy, improving the performance of farrowing and the productivity of the resulting young.
