Six isocaloric (3.65 kcal/g), isonitrogenous (35% db protein), ingredient blends were prepared with 0, 17.5, 20, 22.5, 25, and 27.5% DDGS and other common ingredients, including soybean meal, corn, fish meal, whey, soybean oil, and vitamin and mineral mix, in order to produce balanced rations appropriate for tilapia grower diets. The blends were moisture balanced to 15% db, and then extruded in a pilot-scale twin screw extruder. The extrusion process was carried out using two processing conditions: a 2 mm die at 190 rpm (with temperatures ranging from 80 to 110 o C, depending on ...
