Abstract
In the feeding of non-protein nitrogen (NPN) compounds such as urea to ruminants, the NPN compound is decomposed to ammonia in the rumen. To mitigate against toxic effects of the resulting high ammonium ion content of the ruminal fluid, a zeolite, or crystalline alumino silicate cation exchange material, is introduced into the rumen and maintained therein so that ammonium ions formed by NPN decomposition are accumulated during the post-feeding fermentation period, and later released by the regenerant action of saliva entering the rumen during rumination.
