Use of (olive cake, sugar beet pulp and molasses) as non-conventional energy feed sources in Nile tilapia (Oreochromis niloticus) diets [electronic resource].

This study was designed to determine the effect of practically replacing yellow corn with non-conventional energy sources at (10,20% Olive cake and 10,20% Sugar beet pulp with or without 3% Molasses). A total number of 180 Nile tilapia (2g) were randomly distributed into nine experimental treatment groups each in two replicates, and were fed daily at a rate of 3% of fish live body weight through 10 week experimental period, to study the effect of nine diets contained 32% crude protein on growth performance, feed utilization, body composition and economical efficiency. The results showed that yellow corn energy could be replaced by (10 and 20% Olive cake), without harmful effect on the performance and feed utilization of fish. Results also showed that best growth performance was recoded with control groups followed by fish fed diets containing (10, 20% Olive cake). But the diets contained (10, 20% Sugar beet pulp) and (10, 20% Sugar beet puip and 3% Molasses) showed the lowest values of growth performance and protein utilization. Carcass composition of the experimental fish was relatively affected by different dietary treatments. Cost benefit analysis showed that low profit index and high incidence cost were obtained by the control diet.
