Manure Production (Volume & Weights)

The total manure produced on a farm is related to the animal production system, the number of animals on the farm, and the manure collection and treatment system being utilized. In liquid systems, the production of manure is often reported in gallons per animal per year or gallons per 1,000 birds capacity per year. For dry or solid systems, the production is reported in tons per animal per year or tons per 1,000 bird capacity per year.
