This study was carried out to investigate the reproductive and growing performances in sow farms located in Chungnam. Data collected from a total of 15 sow farms divided into 3 farm groups for 1 year were analyzed. The results obtained were as follows; The average of sow at small and large farms were 114.25 and 487.88 heads, respectively. And then, the difference among 3 groups in sow farm was not found significantly in farrowing rate. The significant difference among 3 farm groups was significantly found(p<0.05) in total litter size. The litter size born alive at sucking in small sow farm and middle farms were 9.93, and 10.48 pigs. The difference between small and large farms in number of pigs at weaning were significantly shown 8.89, and 9.35 pigs(p<0.05), respectively. The difference among 3 sow farms for ages at weaning showed significantly (p<0.05). The cycles of farrowing rate per year in small, large and middle farms were 2.17, 2.23 and 2.32, respectively. The significant difference among 3 sow groups was found in farrowing rate(p<0.05). The growing rate up to weaning for middle farms was significantly the higher level(94.70%) than that for other farms(p<0.05). The differences among 3 farm groups for marketing weight were not significantly shown.
