1LBW, litter birth weight; LVAR, litter variation; STAY, stayability after second cycle; MAX, maximum cycle number; TNB, total number born; STB, total number stillborn (no log-transformation for summary); LMO, litter mortality; PIWI, prolonged interval between weaning and first insemination; GLE, gestation length; FRT, farrowing rate. Sires and dams are the number of sires and dams of progeny with at least one record for that trait.
