Availability of the Nitrogen in Some Ammoniated Products to Bovine Rumen Microorganisms

Abstract

Ammoniated cane molasses (15% protein equivalent), ammoniated invert cane molasses (33% protein equivalent), ammoniated corn cobs, ammoniated furfural residue, ammoniated bagasse and ammoniated bagasse extract were tested in vitro as sources of nitrogen for rumen microorganisms. It was found that rumen microorganisms utilized only the ammonia in these products and that the microorganisms did not utilize the “bound” nitrogen in ammoniated invert cane molasses even after an “daptation period” of 123 days.
