Effect of dietary AFD Thr-to-Lys ratio and AFD (Gly + Ser)-to-Lys ratio in treatments 1, 2 and 17 on production performance from 7 to 28 d.1
| Item | AFD Thr-to-Lys ratio, % | AFD (Gly + Ser)-to-Lys ratio, % | CP, % | FI, g | BWG, g | FCR, g/g |
|---|---|---|---|---|---|---|
| T1 (PC) | 64 | 156 | 20.5 | 2,069 | 1,482a | 1.397a |
| T2 (NC) | 55 | 135 | 18.5 | 2,100 | 1,473a | 1.427b |
| T17 | 64 | 156 | 18.5 | 2,154 | 1,538b | 1.400a |
| P-value (LSD) | 0.165 (91.3) | 0.002 (30.1) | 0.028 (0.0226) | |||
AFD = apparent faecal digestible; PC = positive control; NC = negative control; FI = feed intake, BWG = body weight gain, FCR = feed conversion ratio; LSD = least significant differences.
a, b Means within the same column with no common superscript differ significantly (P ≤ 0.05).
