This experiment was conducted to investigate the influence of birth season, gender (castrated male; female) and paternal line (Darby Duroc, DD; Darby genetics Inc., Anseong, Korea & Chookjin Duroc, CD; Rural development administration., Suwon, South Korea) on growth performance and carcass traits in pigs. A total of 2888 piglets [(Landrace x Yorkshire) x Darby or Chookjin Duroc] with average 3 weeks (wk) were used for 22 weeks during each season (spring=608, summer=404, fall=576 and winter=1300). Individual pig body weight (BW) was recorded, and feed consumption was recorded at 2 weeks, 12 weeks and 22 to determine growth performance. Also, after reaching the marketed weight, backfat thickness was determined at last rib and meat grade was divided by the criteria in slaughterhouse. In current experiment, there are no significant difference and interaction between gender and parental line on growth performance like average daily gain (ADG), average daily feed intake (ADFI) and Gain: Feed (G:F) ratio of pigs born in seasons. However, in fall and winter born pigs, females had greater body weight (BW; 8, 16 and final week; P
