Long-term sustainability of the swine industry is impacted by nutrient management. In order to reduce the nutrients phosphorous and nitrogen being produced at operations, some strategies that can be used are particle size reduction and enzyme supplementation. To reduce phosphorous excretion, the addition of phytase was most effective, while reducing nitrogen excretion was most effective when reducing the particle size below 700 mm.
