An assessment of cereal grains and other starch sources in diets for barramundi (Lates calcarifer) - implications for nutritional and functional qualities of extruded feeds

This study examined the digestibilities of whole diets and ingredients of a range of starch/cereal grains when fed to barramundi (Lates calcarifer). The ingredients included wheat, oats, sorghum, triticale, barley, among others. Twelve diets were prepared using a twin-screw extruder to mimic modern aquafeed-manufacturing processes. The diets were then fed to juvenile barramundi and the faeces collected using stripping methods. Significant...
