The aim of this study was to investigate the effect of parity and postpartum day on the behavior of nursing sows and their suckling piglets. Total 36 Landrace or Yorkshire sows(range of parity: 1 to 8) and their litters(range of litter size: 11 to 13 piglets) were assigned with sow's parity($1{\sim}2,\;3{\sim}4$ and 5 or more) and sow's postpartum days(day 1, 7, 14 and 21). The sows were housed in farrowing crates($0.6{\times}2.1m$) located in pens($2.4{\times}1.8m$) with totally perforated flooring. The sows and piglets were conventionally managed. The sows and their piglets behaviors were recorded during the 24 hour period at 1, 7, 14 and 21 days of postpartum. The obtained results from this study were as follows; 1. All the nursing sows in both group made attempts for lateral tying more than for other behaviors for whole days. The order of behavioral frequency at 1 and 3 weeks postpartum according the days of postpartum of sows was lateral tying, ventral lying, standing, sitting, feeding and drinking. The nursing sows at day 1 postpartum spent more time on sitting and standing than the sows at day 7 or more postpartum. 2. The parity of sows did not affected the lateral tying and sitting behavior of nursing sows, however the ventral tying are lowed in $1{\sim}2$ parity of sow group than the other parity group. Standing, feeding and drinking behavior of sows was not showed at any trends according to the sow's parity. 3. In the behaviors of suckling piglets, lying was increased and unsuccessful suckling was decreased until 21 days postpartum. Compared to the 7, 14 and 21 day postpartum, piglets at the 1 day postpartum spent less time for lying and walking, whereas they spent much more time for unsuccessful suckling. 4. According th the sow's parity, their piglets tying and unsuccessful suckling was lowed in $1{\sim}2$ parity sow group, however more than 3 parity sow's piglets behavior are not affected.
