Puffing fish feed has following advantages:
1、In the extrusion process, heat, moisture, pressure and various mechanical action can improve the feed starch gelatinization degree, damage the cell wall fraction in the softening of the fibrous structure, release parts of digestible substances which is surrounded and combined.  thereby enhancing the feed digestibility. So as to enhance digestion of  feed utilization.
