Abstract

Poultry production is improved by treating poultry manure in the growing location with alum in an amount of from about 0.75 to about 1.5 tons of alum per 10000 birds raised, or at least 0.15 to about 0.25 pounds of alum per bird raised. Poultry manure treatment with alum improves weight gain and feed conversion and decreases mortality for birds grown on treated manure as compared with birds grown on untreated manure. The alum-treated manure may also be used as an agricultural fertilizer. When used as agricultural fertilizer in agricultural runoff water studies, plots fertilized with alum-treated manure exhibit decreased concentrations of phosphorus and heavy metals such as arsenic, copper, iron and zinc as compared with plots fertilized with untreated, normal poultry manure.
