🐖 Pig Pregnancy Calculator

🐖 About Pig Pregnancy

This pig pregnancy calculator helps farmers estimate the farrowing date. The average gestation period for pigs is approximately 114 days (3 months, 3 weeks, 3 days), but can vary between 112-120 days depending on breed, age, and litter size.

📊 Pig Pregnancy Stages (Week by Week)

• Week 1-4 (Days 1-28): Fertilization and implantation. No visible signs.
• Week 5-8 (Days 29-56): Increased appetite. Sow may show weight gain.
• Week 9-12 (Days 57-84): Belly begins to enlarge. Udder development starts.
• Week 13-16 (Days 85-114): Significant weight gain. Udder fills. Farrowing approaches!

🏠 Signs Your Sow is About to Farrow

• ✅ Udder becomes full and tight (7-10 days before)
• ✅ Milk can be expressed from teats (24-48 hours before)
• ✅ Restlessness, nesting behavior (piling bedding)
• ✅ Loss of appetite 12-24 hours before farrowing
• ✅ Vulva becomes swollen and red
• ✅ Clear mucus discharge

⚠️ Important Notes

This calculator provides an estimated due date. Always consult your veterinarian for proper prenatal care and farrowing assistance. Provide a clean, warm farrowing crate. Have supplies ready: iodine, towels, heat lamp, and vet contact number.
