Effect of very low protein diets supplemented with limiting and branched-chain amino acids higher than recommended levels on apparent fecal digestibility of calcium, phosphorus, and nitrogen in nursery pigs. (A) apparent fecal digestibility (AFD) of calcium (Ca), (B) AFD of phosphorus (P), and (C) AFD of nitrogen (N) during nursery phase 2 (N2, i.e., days 15–21 of study) and nursery phase 3 (N3, i.e., days 22–42 of study) periods. PC (positive control), standard protein diet; NC (negative control), low protein diet supplemented with limiting amino acids (LAA, i.e., Lys, Met, Thr and Trp); L25, low protein diet supplemented with LAA, 25% more than NRC (2012) requirements; L50: low protein diet supplemented with LAA 50% more than NRC requirements; LB25: low protein diets supplemented with LAA and branched-chain amino acids (BCAA, i.e., Leu, Ile and Val) 25% more than NRC requirements; LB50: low protein diet supplemented with LAA and BCAA 50% more than NRC requirements. The P-values for the diet effects for N2 and N3 phases for AFD of Ca were 0.071 and 0.003, for AFD of P were 0.055 and 0.088 and for AFD of N were 0.619 and 0.457, respectively. a P ≤ 0.05 LB25 vs. PC, b P ≤ 0.05 LB50 vs. PC, c P ≤ 0.05 LB25 vs. NC, d P ≤ 0.05 LB50 vs. NC. ¥ 0.05 < P ≤ 0.1 LB50 vs. L50. The values are means ± standard error of the mean, n = 6
