Abstract

Process is as follows; (a)(I) is chopped into particles and mixed with H2O; (b) HNO3 is added to pH 0.5-3.5; (c) mixt. is cooked for 30-60 min. at 100-125 psig steam press. to break lignin cellulose bonds and convert some (I) to material suitable for use as an animal feed. Simple process readily increases the digestibility of plant cellulosic materials by agricultural animals. In an example, oak wood sawdust was processed as above and was found to contain 27.4% crude fibre (uncooked sawdust, 55.2%), and 65.03% N2-free extract (uncooked, 31.76%).
