BACKGROUND: The tremendous supply and low cost of distillers dried grains with solubles (DDGS) make it an attractive feedstuff for aquaculture diets. Also, several studies have shown that DDGS can be successfully fed to various finfish. The objective of this study was to evaluate the effects of inclusion rate of DDGS (0, 250, 500 g kg−1), feed moisture content (350, 450 g kg−1) and die opening area (die A = 18.85 mm2, die B = 3988.45 mm2) on the properties of the extrudates and on processing behaviour using a single-screw extruder.
RESULTS: Increasing the inclusion rate of DDGS resulted in …
