Composition and manufacturing method of ruminant roughage containing Pinus koraiensis twigs fermented by anaerobic procedure

摘要

PURPOSE: A method for manufacturing a roughage composition containing an unaerobic fermentation product of browses(twigs and leaves) of Pinus pentaphylla instead of rice straw as a main component is provided. Therefore, the browses of Pinus pentaphylla are useful as a substitute roughage source for rice straw. CONSTITUTION: A roughage composition contains an unaerobic fermentation product of browses of Pinus pentaphylla as a main component and additionally a nutrient supplement such as urea or calcium carbonate. The browses of Pinus pentaphylla are ground into a size of 3 to 10mm and then anaerobically fermented with a suitable amount of moisture, a fermentation promoter and a deterioration preventing agent to give a roughage composition for feeding livestock. The roughage composition has a moisture content of 55 to 70%.
