¹TNB1 = total number of piglets born in first parity; NSB1 = number of stillborn piglets in first parity; PM1 = piglet mortality between birth and weaning in first parity; TNB2 = total number of piglets born in later parities; NSB2 = number of stillborn piglets in later parities; PM2 = piglet mortality between birth and weaning in later parities; AFF = age at first farrowing; FFI = first farrowing interval; SFI = second farrowing interval; observations with weight < 1 were discarded
