Digestibility Of Ingredients In Two Pelleted Diets By Macrobrachium Rosenbergii (De Man)

The digestion coefficients of nutrients in two diets containing 30% and 40% protein were evaluated in the Malaysian giant freshwater prawn Macrobrachium rosenbergii. Chromic oxide was used as an internal marker for the evaluation of digestibility. Evaluations were carried out with juvenile and...
