Abstract: The study was conducted to investigate the effect of excess lysine on performance, viscera weight and abdominal fat in broilers during starter (0-3 weeks) and growing (4-6 weeks) periods. Two hundred and forty days old broiler chicks were reared using completely randomized design with four treatments groups (T1 = 0%, T2 = 0.2%, T3 = 0.4%, T4 = 0.6% excess lysine ) having three replicates of 20 birds in each group for 6 weeks. Results showed that the treatments groups there had no significant differences on feed intake at the rearing period. Weight gain and feed conversion ratio was better (p<0.05) in treatment groups than T1 (control group). There were significant differences in percentage of abdominal fat weight and offal weight between treatments (p<0.05) in total period. Overall, we can suggest that T3 (0.4% excess lysine) had better performance and carcass yield than other treatments.
