^a–cMeans within a row with different superscripts differ (P < 0.05).

¹Day zero is the day of farrowing.

²Confidence limits for stillborn.

³CY = colostrum yield, CI = colostrum intake from birth until 24 h after birth of the first piglet in the litter.

⁴Average piglet weight gain in the period from birth until 24 h after birth of the first piglet in the litter.
