In order to reduce the amount of phosphorous in manure to decrease environmental effects, nutrient management for pigs is crucial. By decreasing the amount of phosphorous in feed to its requirement, the amount of phosphorous excreted is reduced. Phosphorous requirements were determined to be 6.2 g/d at a protein deposition range of 153 to 180 g/d for grower pigs. If the pigs are out of this range the required amount of phosphorous may vary. By decreasing the amount of phosphorous, excess costs are decreased and the swine industry becomes more sustainable.
