1Umbilical cord blood was collected from a total of 656 piglets (623 live-born and 33 stillborn pigs) from 43 sows (Fast Large White × PIC Landrace) immediately after birth and analyzed in a handheld iStat portable clinical analyzer (iStat Alinity, Abbott Point of Care Inc., Princeton, NJ).
2Colostrum intake in 24 hr was calculated using the equation from Theil et al. (2015).
3Log transformed values were used.
