Abstract

An improved two step method for producing feeds for ruminant animals whereby carbamides, particularly urea and biuret, are reacted with fermented proteinaceous agricultural products and wastes with the aid of an aliphatic dicarboxylic acid catalyst to produce a highly palatable nutritive feed which releases protein and protein equivalent nitrogen in a slow and controlled manner in the rumen. First stage of the method mechanically destroys the cellular structure of the fermented agricultural products and wastes, removes unpalatable acids, aldehydes and amines by stripping with hot gas, and partially completes the adduct-forming reaction between proteinaceous sugars, fats, and cellulose in the fermented material and the carbamides in a homogeneous liquid phase at temperatures of between 80.degree. and 100.degree. C. In the second stage, adduct reaction and drying is completed in a hot gas fluidized reactor at temperatures between 100.degree. and 150.degree. C.
