摘要: Phase-feeding (PF) was tested to evaluate its efficacy compared with NRC recommendations for broilers. Two modified PF regimens were also that involved lowering amino acid requirements predicted by linear regression equations 10% (PF10) and increasing the slope of 15% (PF15). Experimental diets fed from 43 71 d. Broilers regimen given a single diet throughout experiment, whereas PF, PF10, PF15 series four (43 50 d, 57 64 d). At no differences (P 0.05) observed in carcass, breast, wing, or leg yield, but abdominal fat increased < PF10 relative broilers diet. Economic analysis indicated may lower cost feed consumed per unit weight gain breast yield
