Effects of chemical, physical, or enzymatic treatments on concentration of DE and ME and on digestibility of energy, organic matter, and fiber in DDGS fed to growing pigs

Distillers dried grains with solubles (DDGS), a co-product of the ethanol industry, is an affordable source of energy and protein in pig diets. DDGS contains more gross energy than corn, but the energy is less digestible because of the high concentration of insoluble fiber in DDGS. If the fiber in DDGS could be made more soluble with pretreatment, its feed value would be improved.

An experiment was conducted to determine the effects of physical, chemical, and enzymatic pretreatments on the concentrations of digestible (DE) and metabolizable (ME) energy and on the apparent total tract digestibility (ATTD) of gross energy, organic matter, acid detergent fiber (ADF), and neutral (NDF) detergent fiber.
