Different superscripts within rows for each parameter indicates that there is a significant difference (P ≤ 0.05).
a Average daily liveweight change (g/d) was calculated based on the change in LW over the total feeding period (including 14 d adaptation period).
b Level of significance for the interaction between dietary treatment (T) and day (D).
