Abstract: Digestibility of dry matter and nutrients by Catla catla was investigated from three feed ingredients-Azolla, soybean and silkworm pupa incorporated at levels ranging from 0-40% incorporated into a diet consisting equal amounts of rice bran and groundnut oil cake.Total dry matter digestibility (DMD) and protein digestibility of Azolla diets were comparable with the control diet up to 20% incorporation (p>0.05),reducing there after (p<0.05).On the other hand, fat digestibility increased with the level of Azolla incorporation (p<0.05).The digestibility of nitrogen-free extract (NFE) was higher (p<0.05) at 10 and 20% levels.DMD and protein digestibility of soybean diets were higher (p<0.05) at 40% incorporation, and that of fat and NFE were higher (p<0.05) at both 30 and 40% levels.Protein digestibility of silkworm pupa diets showed no difference (p>0.05) with that of the control, while fat and NFE digestibility were higher above 20 and 30% pupa incorporation, respectively.The results of this study would be useful in formulating diets for catla using the ingredients tested.
