^aData are least square means for each dependent variable represent 20 to 24 observations per sow treatment, and 14 to 16 observations per post-weaning dietary treatment
^bThere was no interaction between sow treatment and post-weaning dietary treatment for any of the morphology parameters, therefore, the interaction term was removed from the final model and only main effects are shown
