| description | Today, in Ukraine, the issue of producing high-quality and safe livestock products is solved by the introduction of intensive technologies that involve the use of various feed additives, including vitamins, probiotics, prebiotics, macro- and microelements. In recent years, the development of feed additives using live cultures of microorganisms, so-called probiotic products, has attracted much attention of scientists. The strategy in the creation of these products is aimed, first of all, at ensuring the physiological needs of the animal body in biologically active substances. The addition of probiotic supplements to feed increases the bioavailability of nutrients, health, immunity, performance and conservation of animals. Probiotic feed additive EnzActive is a special product on the market of feed additives, the addition of which to feed is aimed at reducing, and in the future, the complete elimination of the use of antibiotics in animal feeding. The article examines the mechanism of action of active fodder yeast on the body of farm animals and proves that the use of active fodder yeast in animal feeding helps reduce the cost of feed due to better assimilation by the animal's body and reduction of morbidity among animals. Methods of introduction of active fodder yeast into the technological process of compound feed production are analyzed. On the basis of theoretical and experimental data, a structural scheme for the extrusion of grain raw materials with active fodder yeast is proposed, which involves preliminary mixing with crushed grain raw materials to obtain a highly homogeneous and stable composition. The physical properties of the feed additive, which includes corn grain and active feed yeast EnzActive, were experimentally determined, which indicate that, compared to the loose, extruded feed additive, it has the following advantages: the mass fraction of moisture decreases by 24.4%, the natural slope angle increases by 11, 6%, the flowability decreases by 48.2%, and the volumetric weight decreases by 24%. When extruding corn grain with active fodder yeast, the degree of starch dextrinization is 59%, and the extrudate expansion index is 2.3. Microbiological indicators were determined, which indicate that the number of yeast cells in extruded grain with active feed yeast EnzActive was only 6% compared to the number of yeast cells in untreated corn grain with active feed yeast. |
