Gestation length in swine is commonly described as which phrase?

• A. Three months, three weeks and three days
• B. Nine months
• C. Twelve weeks
• D. One year

Answer: (A)

Gestation length in swine is described this way because the average period from conception to farrowing is about 114 days. Saying three months, three weeks, and three days provides a practical, memorable shorthand that matches roughly 90 days (three months) plus 21 days (three weeks) plus a few days, totaling around 114 days. This phrasing helps producers estimate farrowing without relying on exact calendar dates, and while there is some variation by breed and individual, it’s still the standard way to convey swine pregnancy length. The other options don’t fit because they describe human or shorter timeframes that don’t match pig gestation.
