Experiment Station Bulletin 432, May 1967

The gestation period of a gilt (meaning she has never farrowed, given birth) or sow (an older, “experienced” female) is three “3”s: Three months, three weeks, and three days. The months are 30 day months and not calendar months! This means that after the female has been bred, there will be little squealers 114 days later, usually arriving during the night (female sows are light sensitive when it comes to farrowing).
