Animal Performance, Carcass Quality, and Tissue Residues with Beef Steers Fed Forage Sorghum Silages Grown on Soil Treated with Liquid Digested Sludge

摘要

Processed sewage sludges are a renewable resource which have potential as a fertilizer material on agricultural land. Forage sorghum (Sorghum bicolor) silages, grown on soil treated with Pensacola liquid digested sludge (LDS) turned under prior to planting, were fed as the main ingredient in the diet of beef steers to determine the effects on animal performance, carcass quality, and concentrations of selected potentially toxic metals in liver, muscle, and kidney tissues.
