• • • Improving carbohydrate concentration and production efficiency of soybean fodder concentrate
Feed value or nutrition defines the ability to provide livestock with essential nutrients and energy, required for normal physiological
activity, such as organ and tissue development, milk secretion and energy reserve. Chemical composition, affecting feed value, varies due to environment conditions. Therefore, developing feed additives, feed-stuffs and premixes has to consider regional condition, livestock species, age and physiological state as well as product quality and payback. The Amur region is the main producer of soybean. Effective soybean diet in livestock feeding implies breakdown of antinutrients and favour protein utilization. Nowadays a number of methods exists, improving total protein nutrition of soybean. The most effective ones are hydro- and barothermal processing. Increasing feed effectiveness requires production of optimal forage mixtures, satisfying livestock needs with energy, carbohydrate, lipids as well as vitamins and minerals. Previous reports on chemical composition, economical efficacy and production scales proved maize to be an ideal carbohydrate additive for soybean, combined with the latter for the extrusion. Optimized extrusion of soybean-maize grain mixture improves sugar-protein ratio of concentrates and capacity of extrusion press. Mathematical models, presented in the report and based on the obtained data, define the production process and are recommended for forage production.
