Abstract:
This experiment was carried out to evaluate the effect of using cassava
flour as a carbohydrate source to replace wheat flour in diets for Tilapia
Oreochromisniloticus. Five isonitrogenous (28% crude protein) diets formulated
by replacing 0, 25, 50, 75, and 100% of wheat flour by cassava flour were fed to
fish (mean initial weight of 1.23 ± 0,01 g) three times daily at a feeding allowance
of 10% body weight per day for 56 days. Fish fed diets with 0, 25 and 50%
replacement had similar (P > 0.05) specific growth rate and feed efficiency. Fish
fed diet with 75% replacement of wheat flour by cassava flour had significantly (P
< 0.05) higher for specific growth rate and feed efficiency. Survival was high (75-
91%) and similar for all diets. It is concluded that up to 75% carbohydrate of
wheat flour can be replaced with carbohydrate of cassava flour in diets for Tilapia.
