The swine confinement farmer must contend with two related problems, that of odour control, and of waste disposal. Odour problems can be related directly to manure handling methods. When manure is quickly removed away from the animals, they and the building remain cleaner and odour is reduced. Sources of odour are introduced when the manure is stored nearby, or below the animal quarters.
It is important to control these odours to avoid a variety of problems. These include community complaints, the possible toxicicity of these gases on human and animal health, and lastly to avoid and possible structural damage. This study examines the constituents of the gaseous atmosphere inside the confinement building, particularly those derived from the breakdown of the animal wastes. The odour properities and toxicity to health is then taken into consideration.
