Effect of dietary AFD Thr-to-Lys ratio and AFD (Gly + Ser)-to-Lys ratio in positive control (T1), negative control (T2) and treatment 17 (T17, comparable ratios as PC) on plasma metabolite concentrations at 28 d.1
| Treatment | AFD Thr-to-Lys ratio, % | AFD (Gly + Ser)-to-Lys ratio, % | CP, % | PFAA, mg/mL | TG, g/L | Glucose, g/L | UA, mg/L |
|---|---|---|---|---|---|---|---|
| T1 (PC) | 64 | 156 | 20.5 | 0.47 | 0.88 | 2.38 | 65.3b |
| T2 (NC) | 55 | 135 | 18.5 | 0.47 | 1.00 | 2.30 | 47.1a |
| T17 | 64 | 156 | 18.5 | 0.50 | 0.92 | 2.36 | 54.3a |
| P-value (LSD) | 0.466 (0.072) | 0.290 (0.155) | 0.750 (0.223) | 0.003 (9.98) | |||
AFD = apparent faecal digestible; PFAA = plasma free amino acids; TG = triglyceride; UA = uric acid; LSD = least significant differences.
a, b Means within the same column with no common superscript differ significantly (P ≤ 0.05).
