Abstract
The information available in regard to the utilization of non-protein nitrogen (NPN) by swine is somewhat limited and conflicting. Therefore, the research presented in this thesis was undertaken to investigate the use of an equimolar mixture of diammonium citrate and diammonium phosphate as a source of dietary nitrogen for growing-finishing swine.
Two experiments were conducted to determine if a portion of the protein in a growing-finishing swine diet could be replaced by non-protein nitrogen from an equimolar mixture of diammonium citrate and diammonium phosphate. Criteria employed to measure the response were rate of gain, feed efficiency, nitrogen retention, and certain blood and carcass characteristics. Because the diammonium phosphate was also considered as a source of phosphorus certain bone characteristics and the retention of calcium and phosphorus were studied.
