A 5x2x3 factorial experiment was used to investigate the effects of 5 ME levels (12.55, 12.30, 12.05, 11.80, and 11.55 MJ/kg) supplemented with or without exogenous enzymes in diets of broilers on the nutrient digestibility and energy improving efficiency over the starter, grower, and finisher phases of growth. The results indicated that the apparent digestibility of DM decreased linearly with a reduction in the ME level in diets for the starter (R2=0.234, P<0.001) and grower (R2=0.362, P<0.001… CONTINUE READING
