Different levels of synthetic lysine amino acid were supplemented to 240 starter broiler chicks randomly distributed to 12 groups of each 20-day chicks and allocated to four treatment diets in a Completely Randomized Design (CRD). T1 (Control) basal diet (0% synthetic lysine); T2 (0.15% synthetic lysine); T3 (0.3% synthetic lysine) and T4 (0.45% synthetic lysine). There was no significant difference (P&gt;0.05) observed between treatments in dry matter, metabolizable energy, crude protein intake, body weight and death rate of the chicks. In conclusion, there were no significant changes for all parameters and further amino acid analysis of the feedstuffs is required and extra addition above 0.45% synthetic lysine of T4 need to be added in this experiment which numerically improved the chick’s performance. Further experiments were recommended to evaluate the levels of lysine amino acid in the feedstuffs and its inclusion level in to the diet of modern broiler strains.
