In a process for preparing a feedstuff for ruminants, a cellulosic material, e.g. straw, is ammoniated by treatment with gaseous ammonia or by admixing with an NH4 cation generating agent. The cellulosic material is coated with a liquid proteinaceous material, e.g. liquid yeast, and the coated material is dried at an elevated temperature to volatilize the ammonia. The resultant feedstuff has an enhanced nutritional value, the digestibility of the cellulosic material is improved, and the proteinaceous material protected against digestion in the rumen. |
