- ... Digestibility and utilization of a fishmeal-based diet extruded at 103 or 137 degrees C were examined. Each of the diets was fed to 0.5-kg rainbow trout in nine tanks supplied with freshwater. Specific growth rate was significantly (P < 0.05) elevated for trout fed the feed extruded at 137 degrees C. The apparent digestibilities of protein and energy, feed conversion ratio, retentions of nitrogen ...
