What is a common way to reference the gestation length of swine?

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

Answer: (C)

Gestation length in swine is typically quantified in days and is about 114 days, which is conventionally expressed as three months, three weeks, and three days. The breakdown adds up to 114 days (90 days for three months, 21 days for three weeks, and 3 days), making this phrasing the standard way to reference a sow’s pregnancy timeline. It differs from human pregnancy, which is about nine months, and from shorter or longer timeframes like twelve weeks or a full year. Keep in mind there is some natural variation, with gestation commonly ranging roughly 111–116 days depending on breed and individual factors.
