МОЖЛИВОСТІ ВИКОРИСТАННЯ МАЛОЦІННОЇ РИБИ У КОРМОВИРОБНИЦТВІ
A method for manufacturing a feed mixture by extrusion of low-value fish and grain was proposed. The article presents a study about the definition of the most important characteristics of feed mixture before and after extrusion. Physical properties (flowability, bulk density, angle of repose) of the feed additive in extruding indicate mixture as component with bad flowability. After extrusion physical properties of the feed mixture are improved, it allowed efficiently store and transport the components in the feed mills. As a result, the extrusion of the feed mixture, the amount of starch decreased by 36.9%, crude protein 3.1%, crude fiber 4.3%, the amount of water-soluble carbohydrates increased 5.5 times. As a result of the extrusion nutrient digestibility was increased.
