This study was conducted to determine the main effects of breed, farrowing year, season, parity and generation on gestation length, litter size at birth, and pig weight at birth, 21 days and weaning in swine. Large Yorkshire and Duroc were superior in litter size at birth and Landrace was heavier in the preweaning weight than in the other breeds. The effect of farrowing year on the litter size and pig weight at birth was significant at 5% level. There was a highly significant difference at 1% level for pig weight at 21 days and weaning
