The unique ability of ruminants to utilize non-protein nitrogen (NPN) in place of dietary protein has been extensively investigated.Several NPN compounds such as urea, ammonium salts, biuret and isobutylidene diurea (IBDU) have been studied. Biuret and IBDU which release ammonia slowly in the rumen are less liable than urea to lead to accidental toxicity, but neither biuret nor IBDU is found to be superior to urea in nitrogen utilization. There was, however, little evidence as to the value of various amide-nitrogen except for the amides of asparatic and glutamic acid.<BR>In the present study, the effects of dietary propionamide on digestibility of feeds in goats were investigated as both potential nitrogen and energy sources.
