However, as the day of foaling nears, the changes become more discernible. A CTUP above 2 SD[standard deviations]of the established normal range after 271 days of gestation suggests placental failure and pending abortion (8 mm between days 271 and 300; 10 mm between days 301 and 330; and 12 mm after day 330). There is no heat, no signs of dripping, etc, but I don't want to .
