 note = {Feeding experiments were carried out by using a purified diet varying levels of
protein (casein) on the fish, Tilapia zillii. Also, the effects of dietary energy levels
on growth of T.zillii were examined.
The optimum protein levels for T.zillii were determined to be 35-40% when casein
was used as a sole protein source. The body weight gain increased in proportion
to the dietary protein levels within the range of 0% to 35%. The utilization of
protein by this fish was also evaluated with respect to protein efficiency ratio (P. E.
R.), net protein ratio (N. P. R.), net protein utilization (N. P. U.), and feed efficiency. P. E. R., N. P. R. and N. P. U. decreased with the increase of casein levels
in the diets.
The body weight gain of T.zillii was improved with the increase of calorie of
diets, with suggestion that lipids are effective as energy sources more than carbohydrates.},
