Abstract
This NebGuide explores options for altering the nitrogen and phosphorus content of swine manure.
There are situations in which it is necessary to change the nutrient content and/or the odor-producing potential of swine manure in order for pork production to thrive. For example, current Nebraska Department of Environmental Quality (NDEQ) permit procedures for livestock facilities require producers to document that sufficient land is available for crop use of the nitrogen (N) in manure. If sufficient land is not available for managing nutrients in manure, producers can alter the nitrogen and phosphorus content of swine manure by modifying the pig's diet. The objective of this article is to review how to alter the nitrogen and phosphorus content of swine manure and the emission of ammonia and odor from pork production systems by modifying the pig's diet.
