Use of some agro-industrial by products in Nile Tilapia fish diets

| Abstract |
In the present study, utilization and nutrients digestibility of agro-industrial by-products such as apricot seed kemels (ASK) and mango seed kernels (MSK) by monosix Nile tilapia (Oreochromis niloticus) fingerlings, were investigated under laboratory conditions. The two ingredients were incorporated at separate levels of 0, 15, 25, 35 and 45% instead of yellow corn. The feeding period lasted for 140 days. In general, in the first experiment, the results showed that yellow corn can be partially replaced by ASK on the levets of 15, 25 and 35%. In the second experiment, the substitution of MSK for yellow corn at replacement levels of 15, 25 and 35% had no adverse effect on the performance of the fish. In addition the results showed that the preferable FCR was recorded by fish given treatment TA5 (45% ASK). While, the lowest values were obtained by fish given the control diet TA1. Fish fed the experimental diets in which yellow corn was replaced by ASK at all levels tested were superior significantly (P>0.05) in the FCR compared with the fish fed the control diet. In the second experiment, the best FCR was obtained by the control TM1, when compared to the lowest FCR value which recorded by TM5 (45%).Therefore, partially substitution of yellow corn with ASK or MSK can be used in feed Nile tilapia (O. niloticus) fingerlings.
Keywords: Nile tilapia, agro-industrial by-products, apricot seed kernel, mango seed kernel, nutrients digestibility, growth performance.
