ResumoDataReproductive traits were observed of the 3,078 litters of 2,101 sows farrowing between Jan, 1975 to Dec, 1998 at National Livestock Research Institute, RDA in Korea.The total number of animals in the pedigree file was 32,286.The traits included in simultaneous analysis were total number of pigs born (TNB), number of pigs born alive (NBA), total pig weight at birth (TWB), and average pig birth weight (ABW).Data that were greater than three standard deviations from the mean were eliminated.The sow records with service sire record within three standard deviations from the mean were used.Number of records, year of birth, year of farrowing, season of farrowing, month of farrowing, and parity are presented in Table 1.The number of service sire and sow by year of farrowing are presented in Table 2.
