The experiment reported herein considered the effect of using solvent extracted thevetia oil which was subjected to heat treatment at 110°C for 25 minutes. Four experimental diets consisting of a basal diet and three other diets in which 2.5, 5.0 and 10% of the control diet was replaced by the thevetia oil were formulated and fed to broilers during the finishing stage (4 - 8 weeks). Eighty broilers were individually weighed and randomly divided into four groups of 20 birds each and these were further divided into 4 replicates of 5 birds each. The four groups were then randomly allocated to the four dietary treatments. Feed Intake and Feed: Gain improved with increase in thevetia oil concentration (P<0.05). Flowever, there was a 10 significant effect of the dietary treatment on weight gain. increasing the concentration of thevetia oil improved the retention of both protein and fat (P<0.05). It was concluded that solvent extracted thevetia oil will serve as a valuable feed ingredient for finishing broiler if a mild heat treatment is employed since Some of the toxic compounds in it are probably thermolabile.
