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.
