Abstract
Feed alone comprises from 60-75% of the total cost involved in swine production today. Thus by reducing feed costs direct benefits should be realized by both the producer and the consumer.
New feedstuffs, and new methods of feeding existing feedstuffs are being explored in order to increase total protein production. The use of non-protein nitrogen (NPN) for swine seems to have promise. However, the reports available conflict as to the utilization of NPN by growing-finishing (G-F) swine.
The research reported herein was conducted to:
(a) Determine the level of lysine, methionine, tryptophan, and threonine, which would increase the utilization of NPN by swine.
(b) Determine if a portion of the protein in swine diets can be supplied by NPN without critically affecting performance.
(c) Determine the value of ammonium phosphate as a nitrogen and phosphorus source for G-F swine.
