Resumen

Apparent dry matter and protein digestibility of four animal and three vegetal ingredients and diets with them included, were evaluated for pre-adult Cherax quadricarinatus. The ingredients were: two sardine meals (67% and 58% crude protein), squid meal, red crab meal, soy paste, textured wheat, and sorghum meal. A reference and seven experimental diets were formulated including 14.5% of each ingredient in the reference diet, and 0.5% of chromic oxide as a marker. Vegetal ingredients and the corresponding diets, had higher digestibility than animal ingredients. Textured wheat, soy paste, and sorghum meals showed an excellent dry matter/digestibility (> 86%). The digestibility of protein was better in textured wheat, and soy paste meals (> 87%). Some animal ingredients such as, squid meal, and sardine meal 67% CP, had acceptable dry matter digestibility (over 65%). It is concluded that pre-adult redclaw is omnivorous and able to efficiently consume vegetal and animal ingredients, but they can digest better the vegetal ingredients.
