Description: Odor control is a major problem con fronting confined livestock operations. Anaerobic decomposition is the primary cause of odors. Two basic approaches can be used to control or reduce odors from livestock facilities. The preferred approach is to use proper design and management of waste facilities to prevent odor formation. The alternative approach is to treat the odor after it is established. Today there is a wide variety of products being sold to treat and prevent odors in feedlots, liquid manure storage tanks and lagoons. There are six categories of odor control agents: 1. Masking agents are mixtures of aromatic oils which have a strong particular odor of their own designed to cover up the manure odor with a more desirable one. 2. Counteractants are mixtures of aromatic oils that cancel or neutralize the manure odor so that the intensity of the mixture is less than that of the constituents. 3. Digestive deodorants contain bacteria or enzymes that eliminate odors through biochemical digestive processes. 4. Adsorbents are products with a large surface area that may be used to adsorb the odors before they are released to the environment.
