Method of manufacturing a ruminant feedstuff with reduced ruminal protein degradability

摘要

A feedstuff with reduced ruminal protein degradability is prepared by mixing a carbohydrase enzyme with a material suitable for livestock feed and steeping the mixture under suitable conditions for the carbohydrase enzyme to hydrolyze carbohydrates contained within the material to reducing forms. The mixture is then heated to induce browning so that the protein contained within the material is rendered inert to ruminal degradation. The carbohydrase enzyme may be supplied to the steeping step by the addition of a microorganism capable of secreting the enzyme. A method of feeding a feedstuff with reduced ruminal degradability is also provided.
