Naturwissenschaftliche und technologische Aspekte eines mechanisch‐chemischen Strohaufschlußverfahrens

To enhance the digestibility of wheat straw as an animal feedstock a partial delignification by action of 1percnt; aqueous alkali in combination with mechanical pre- and after-treatment steps is proposed. On the basis of in vitro digestibility by cellulase the influence of various process parameters on the effect obtained is summarized. Sheep feeding studies comparing original and chemomechanically pretreated straw confirm the suitability of the process-principle proposed for upgrading cereal straw. The practical feasibility of the process is considered with regard to animal nutrition and technology.
