Odors associated with livestock manure represent a growing challenge for livestock producers. Livestock production trends such as more animals per farm and expanded reliance upon manure storage have added to the odor muisance. Implementing other environmentally friendly practices such as manure nutrient management and maintenance of surface crop residues for soil conservation also have resulted in additional odor challenges.
Odors originating from livestock wastes are a common source of irritation between producers and neighbors. Confrontations may lead to more stringent local zoning regulations, greater scrutiny of other farm environmental issues, and litigation.
This publication summarizes the underlying causes of livestock odor nuisance, reviews prevention and treatment options, and allows an individual to self-assess design and management procedures for potential risks.
