Amino Acid and Mineral Manipulation in Pig Diets to Reduce Nitrogen and Odors in Pig Manure

Recent increased public concern, legislation and environmental regulations have focused on pollution and have created a major threat to the viability and growth of the pork industry. Even though water pollution control has been a major focus of regulations, recent public concerns and lawsuits have revolved around odors from pork operations. Most research has focused on measuring odor and gas intensity and occurrence with proposed attempts to reduce or mask odors (Miner, 1995). The first line of defense against any emitted aerial contaminant is source control. In the case of swine odor, the obvious source control technique is diet manipulation.
