^a Sow parity during initial parturition. Parity 1 is defined as a gilt having her first litter
^b All sows regardless of parity were used for group All statistical analysis
^c Only parity 1 and 2 sows were used for group Y (young sows) statistical analysis
^d Only parity 3 to 8 sows were used for group M (mature sows) statistical analysis
^e Diet is peripartum dietary treatment containing 0, 0.5 or 2.5% spray dried porcine plasma that was fed only during the initial parturition from entry in maternity through day 5 of lactation
^f Original sow parity at initial parturition and number of sows that had their next parturition
