About Swine Gestation
The average gestation period for swine (pigs) is 114 days (3 months, 3 weeks, and 3 days) with a normal range of 112 to 116 days. This calculator helps you determine the expected farrowing date based on the breeding date.
Pig Pregnancy Care Tips:
- Provide proper nutrition with increased feed in the last trimester
- Ensure clean, comfortable housing with adequate space
- Monitor for signs of approaching farrowing (restlessness, nest building)
- Prepare a clean farrowing area with proper bedding
- Have necessary supplies ready for farrowing

- Screenshot the page.
- Bookmark the link with pre-filled dates (e.g.,
?date=2024-06-01).
8. What care should I provide as farrowing nears?
🛠️ Answer: The tool auto-generates advice based on the pregnancy stage:
- Late gestation: Prepare a clean, warm farrowing pen.
- Imminent farrowing: Watch for restlessness, nesting behavior, or milk production.
9. Does breed affect gestation length?
🔬 Answer: Slightly. Most breeds fall within 112–116 days, but:
- Large breeds (e.g., Yorkshire) may trend toward 116 days.
- Small breeds (e.g., Vietnamese Potbelly) may deliver earlier.
10. How can I improve accuracy?
📆 Answer:
- Record exact breeding dates (not just “semen exposure” dates).
- For AI (Artificial Insemination), use the last insemination date.
- Track heat cycles to confirm successful breeding.
