Influence of dietary nitrogen content and source to improve growth performance and lean gain in finisher pigs

Daniel Columbus- Previous trials done in grower pigs have shown that it is possible to replace some dietary protein or amino acids (AA) with a source of non-protein nitrogen (NPN) such as ammonium phosphate, while maintaining growth performance. However, the impact of dietary nitrogen (N) content and source on finisher pigs is not known.
In a trial, finisher pigs were assigned to diets either deficient in N, or a diet with sufficient N achieved by supplementing intact protein, or a diet with suf
