Effects of Reduced Crude Protein and Fiber Supplementation on Nitrogen and Phosphorus Utilization and Availability

In recent years, animal agriculture has been surrounded by concerns of environmental contamination and degradation. To reduce potential environmental hazards, researchers have tried various practices to reduce the amount of nutrients being excreted in swine manure and ammonia emissions from manure contributing to diminishing air quality. To prevent further environmental concerns, diet modification has become an alternative to reduce unutilized dietary nitrogen (N) and phosphorus (P).
