Relative content of total IL18 (pg) in uterine flushing collected from gilts (n = 4/day/status) on days 0, 5, 10, 12, 15 and 18 of the estrous cycle (open bars) and days 10, 12, 15 and 18 of pregnancy (black bars). A day × status interaction (P < 0.05) was detected for total IL18. Bars without a common superscript represent a statistical difference.
