Values are least square means and pooled SEM calculated in pigs slaughtered at d7 and d28, n = 6/group. P (effect of formula) and age effects are presented. Differences were considered significant when P < 0.05 but trends are presented when 0.1 < P < 0.05. Means with a different superscript letter differ at P < 0.05.
