Özet:

 

An experiment was set to determine the optimal plant based lipid of soy bean and maize on the growth and feed  utilisation of Oreochromis andersonii. Three isonitrogenous diets containing 30% crude protein with increasing dietary lipid  levels (10, 15, and 20%) were provided at 5% live body weight to triplicate groups of 10 fish replicated four times for 55  days. There were no significant differences (P>0.05) in growth indices (final mean weight, body weight gain (BWG) and  specific growth rate (SGR)) and feed utilisation (protein efficiency ratio (PER) and apparent feed conversion efficiency  (AFCE)) determined. Second order polynomial regression of BWG on lipid level (Y = -0.0043x2 + 0.1284x + 21.499)  showed 14.9% to be optimal. The most economical dietary lipid level is below 10% lipid level as indicated by the negative  linear regression (Y = -0.1766x + 303.85). Of the lipid levels used, 10% appears to meet the minimum requirement for this  species. 	 	 		 .
