Abstract
The present study was conducted at the fish research laboratory, Faculty of Agriculture, Minufiya University, Egypt; therefore, two separated experiments were conducted in order to study the following: 1- The first experiment investigate the effect of replacing fish meal protein in Nile tilapia, Oreochromis niloticus (L.) diets and utilizing of treated jojoba meal seeds , exposed jojoba for hot water vapor at temperatures of 120 ° c for half an hour to get rid of toxic simondsin and that cause multiple adverse effects on fish from anorexia. The results of this study revealed that, the fish fed diet (B 25% JM) had significantly (P £ 0.01) the best growth performance and feed utilization parameters from those of fish fed control diet A and all other diets.. From the above results and the economic evaluation of the study it can be concluded that, up to 25 % of fish meal protein can be replaced by Jojoba seed meal protein in fingerlings Nile tilapia diets without decreasing the growth performance and feed utilization parameters .
2-This experiment investigate the effect of replacing fish meal protein in Nile tilapia, Oreochromis niloticus (L.) diets and utilizing of a mixture of different plant protein sources in grow-out phase. The results of this study revealed that, the fish fed diet B had significantly (P £ 0.01) the best growth performance and feed utilization parameters from those of fish fed control diet A and all other diets. Chemical composition of fish flesh crude protein and crude fat (dry basis %) and apparent digestibility coefficient of crude protein and crude fat of the fish fed experimental diets B and C did not differ significantly (P > 0.05) from those of fish fed the control diet A. From the above results and the economic evaluation of the study it can be concluded that, up to 25 % of fish meal protein can be replaced by a mixture of different plant protein sources in fingerlings Nile tilapia diets without decreasing the growth performance and feed utilization parameters .
