Experimental diets (Phase II and Phase III) were fed for 35 d (indicated as d 0–35, corresponding to d 7 to d 42 post-weaning), followed by a common diet for 14 d (indicated as d 36–49)

Means with different superscripts within a row were found to be different at a significance threshold of P ≤ 0.05 (^a,b) or to show a tendency when at 0.05 < P < 0.10 (x,y), based on the Tukey honest significant difference test

¹Control diet supplemented with Peptiva and MOS (formulated to provide 100% of required amino acids for weaned pigs – NRC 2012)

²Control diet supplemented with Peptiva, MOS and a protease (formulated to provide 100% of required amino acids for weaned pigs – NRC 2012)

³Control diet supplemented with Peptiva, MOS and a protease (formulated to provide 90% of required amino acids for weaned pigs – NRC 2012)
