Effects Of Feed And Extruder Parameters On Extrudates Containing Ddgs, S. Kannadhason, Kasiviswanathan Muthukumarappan, Kurt A. Rosentrater

Kurt A. Rosentrater

Twenty seven isocaloric (3.05 kcal/g) ingredient blends were factorially formulated using three levels each of DDGS (20, 25, and 30% db), protein (30, 32.5, and 35% db), and feed moisture content (25, 35, and 45% db), along with appropriate quantities of cassava starch, soybean meal, fish meal, whey, vitamin, and mineral mix to produce a balanced diet for tilapia feed. The ingredient blends were extruded using a laboratory-scale single screw extruder with varying screw speeds (100, 150, and 200 rpm) and extruder barrel temperatures (100, 125, and 150 o C). The resulting extrudates were subjected to extensive ...
