Odor from swine production facilities arises predominantly from manure decomposition. Other odor sources include dead animals, pesticide sprays and manure handling facilities. Each can be handled by appropriate control procedures. Usable odor measurements include odor intensity, which can be measured in the field with a Scentometer and odor frequency, which attempts to determine the % of time that an odor can be detected at a site.
\nControl methods include moisture reduction, covered manure storage tanks, the installations of sprays that scrub the odorous materials from the air and the installation of barriers that cause more complete mixing of odorous materials with odor-free air allowing dilution. The most effective means of reducing odor is initial site selection, areas that do not have close neighbours. There is a general relationship between the perception of odor nuisance, separation distance and the size of a swine production facility. For facilities of 1,000 or fewer animals, the incidence of odor complaints are greatly reduces beyond one-quarter mile and for larger facilities it is a half-mile.
\nThe design and construction of the facility is another means of reducing odor as is operation and management of the facility.
\nDisposal techniques and timing should also be considered in odor control. This includes the timing and techniques used in manure application on fields. If further steps in odor control are needed then there are alternate waste treatment schemes available but they may be in the experimental stage or be costly. Examples of these techniques include aerobic manure treatment, anaerobic digesters, flexible lagoon covers, air scrubbing equipment and odor control chemicals, such as masking agents, odor counteractants, odor absorption and enzymatic products.<\/p>\n","protected":false},"excerpt":{"rendered":"
