MANUFACTURING METHOD OF HIGH PRESSURE SUPPLEMENTARY FEED STUFF AND SUPPLEMENTARY FEED STUFF USING THE SAME

摘要

PURPOSE: A high pressure extrusion coarse fodder and a producing method thereof are provided to prevent the degeneration of the coarse fodder by the temperature or the humidity. CONSTITUTION: A producing method of high pressure extrusion coarse fodder comprises the following steps: preparing coarse fodder raw materials capable of feeding to herbivorous animals(S101); roughly cutting the coarse fodder raw materials before crushing(S103, S105); extruding the crushed coarse fodder raw materials until the surface of the obtained solid coarse fodder is changed for sterilizing noxious bacteria or fungi(S107); and steaming the solid coarse fodder using high temperature steam after adding nutrients(S109). The coarse fodder raw materials are selected from rice straws, corn leaves and stems, bean stalks, or peanut shells.
