Abstract

Dietary composition such as the concentrations of protein/amino acids, fat, and starch+sugar and their ratio, may affect the post-absorptive metabolism of energy, and protein and energy deposition in the body. In a 2×3 factorial block design, the effects of two dietary crude protein (CP) concentrations (high protein (HP) vs low protein (LP); 200/190 vs 170/160 g/kg in grower and finisher phase, respectively) and three dietary fat/starch concentrations (high fat (HF); fat and starch 120 and 350 g/kg, respectively, medium fat (MF); fat and starch 80 and 425 g/kg, respectively and low fat (LF); fat and starch 40 and 500 g/kg, respectively) in iso-energetic diets on the growth performance and body composition of Ross 308 broilers were studied (8 to 38 d). Overall, body weight gain (BWG) of broilers fed HP diets was significantly higher than BWG of broilers fed LP diets (59.6 vs 58.3 g/d; P<0.001) and feed conversion ratio (FCR) of broilers fed HP diets was significantly lower than FCR of broilers fed LP diets (1.65 vs 1.68; P<0.05). BWG of broilers increased as starch concentration in the diet was increased (HF: 55.3 g/d, MF: 59.5 g/d and LF: 62.1 g/d; P<0.001). FCR of broilers improved significantly as the dietary concentration of starch increased and of fat decreased (HF: 1.74, MF: 1.69, LF: 1.57; P<0.001). CP digestibility (77 vs 64%; P<0.05) and protein depostion as proportion of CP intake (63 vs 56%; P<0.001) in broilers fed LF diets was significantly higher than in broilers fed HF diets. It was concluded that dietary energy source and protein level in iso-energetic diets balanced for first limiting essential amino acids influence growth performance and body composition of broilers.
