A process of treating cellulosic plant matter to increase the digestability thereof by animals, in which finely divided plant matter, such as sawdust, rice hulls, bagasse, wheat straw, or the like, is mixed with water and nitric acid or a combination of water, nitric acid and a nonoxidizing acid, su

A process of treating cellulosic plant matter to increase the digestability thereof by animals, in which finely divided plant matter, such as sawdust, rice hulls, bagasse, wheat straw, or the like, is mixed with water and nitric acid or a combination of water, nitric acid and a nonoxidizing acid, such as sulfuric, phosphoric, hydrochloric or acetic, to produce a mixture of about 20% water, ¼to 1% oxygen based on the oven dried weight of organic material, the oxygen being released from the nitric acid, and a pH of 0.5 to 3.5, and cooking the mixture in a pressurized vessel at about 125 psig for 30 to 60 minutes. The cooked product may then be neutralized to raise the pH to a desired level for animal feed.

A process of treating cellulosic plant material to increase the digestability thereof by animals comprising: chopping the cellulosic plant material into particles; mixing the chopped cellulose material with water to thoroughly wet the same; mixing nitric acid with the wet cellulosic material to reduce the pH of the mixture to 0.5 to 3.5; and cooking the mixture at about 100 to 125 psig steam pressure for about 30 to 60 minutes to break lignin cellulose bonds and to convert at least a portion of the cellulose for use as a digestible material suitable as animal feed.
