Objective: This experiment was conducted to investigate the effect of two diets varying in energy and protein (one energy-high-protein-low and one energy-low-protein-high) on performances of Sasso broilers under tropics when offered sequentially. Materials and Methods: A total of 525 Sasso broiler chickens of 3 week of age were assigned into 3 treatments with 5 replicates of 35 birds each. The treatments were: broiler chicken fed (1) Basal diet (A group: control), (2) High energy and low protein diet (E+P diet) in morning and low energy and high protein diet (EP+ diet) in the afternoon (B group) and (3) EP+ diet in morning and E+P diet in the afternoon (C group). At 11 week of age, 30 chickens per treatment were slaughtered to collect blood, abdominal fat, gizzard, liver, heart, kidney, carcass, thigh, breast and intestine. Ultimate pH (pHu) and blood serum concentrations in glucose, triglycerides, total cholesterol, total protein, urea and creatinine were also assessed. Results: Results indicated that feed intake, water intake, body weight, body weight gain, mortality, feed conversion ratio and pHu were similar among treatment groups. However, intestinal length and carcass yield of chickens fed sequentially (B and C) were significantly higher (p<0.05) and their serum creatinine concentration was significantly lower (p<0.05)than those of control group. Abdominal fat, liver weight and serum triglycerides of chickens of B group were significantly lower (p<0.05) than those of A and C group. Conclusion: It was concluded that sequential feeding improved intestinal length, carcass yield weights and serum creatinine and triglycerides of Sasso chickens.
