Manure Handling Systems Reduce Air Contaminants in Swine Barns
Various factors were studied to understand the sources of air contamination in intensive swine operations. Once the factors effect is decreased, the overall effect on air quality should be illustrated. Two manure-handling systems were tested to see which eliminates all manure contamination best; one was a washing gutter and the other was an inclined washed conveyor belt. Zero contamination released into the airspace was not reached in either system, though both systems reduced air contamination from excreta. The simpler and easier to operate system was the washing gutter.
