Letters a and b indicate means within a row with different superscripts significantly differ (P < 0.05).
1ADFI of the sows were recorded from parturition until weaning (22 d).
2Backfat loss = parturition backfat − weaning backfat.
3Litter weight gain = litter weight at weaning − litter weight at birth.
4Weaning alive rate = [litter size at weaning (live) − litter size at birth (live)]/litter size at birth (live).
5Diarrhea incidence = total diarrhea piglets/[litter size at birth (live) × trial days].
6Piglet weight at birth = litter weight at birth/litter size at birth (live).
7Piglet weight at weaning = litter weight at weaning/litter size at weaning (live).
8Piglet weight gain = piglet weight at weaning − piglet weight at birth.
