Dietary treatments were based on 2 phases: phase 1 from d 0 until animals achieved 11 kg of body weight (4 d for pig weaning weight > 9 kg and 14 d for pig weaning weight < 7.5 kg) and phase 2 until pigs achieved 20 kg of body weight (17 d for both weaning weight groups). ^a,b Means within a row with a different superscript differ (P < 0.05). ^X,Y Means within a row with a different superscript tend to differ (0.05 < P < 0.10)
