Two experiments were conducted to assess dietary amino acid density responses on mixed-sex broiler live performance, meat yields, and economics from 36 to 60 d. In experiment 1, broilers were fed a common feeding program to 35 d. Dietary treatments were high (H), moderate (M), and low (L) amino acid density from 36 to 47 d of age and H or L amino acid density from 48 to 60 d of age. Dietary treatments were high-high (HH), high-low (HL), moderate-low (ML), and low-low (LL) during a 60-d production period. In experiment 2, common diets were provided from 1 to 47 d of age. Dietary treatments were H, M, L, and suboptimum (S) amino acid density and fed from 48 to 60 d of age. In experiment 1, increasing dietary amino acid density to HH improved cumulative feed conversion (1 to 60 d) by 4 points over the ML- and LL-fed birds. Broilers provided the HH regimen had 0.6% more total breast meat yield than the LL-fed birds. In experiment 2, broilers fed the H feeding regimen lowered cumulative (1 to 60 d) feed conversion by 3, 5, and 6 points and reduced abdominal fat percentage by 0.28, 0.23, and 0.23%, respectively, compared with the M-, L-, and S-fed birds. Decreasing dietary amino acid density from H to S reduced total breast meat weight and yield by 47 g and 0.82%, respectively. In general, feeding HL (experiment 1) and H (experiment 2) diets increased gross feed margins over the other dietary treatments with diverse diet cost and meat price scenarios.
