1. What is Pig Gestation Period?

The average gestation period for pigs is 114 days (3 months, 3 weeks, and 3 days) with a normal range of 112 to 116 days. This calculator provides an estimated farrowing date based on the breeding date.

2. How Does the Calculator Work?

The calculator uses the standard pig gestation formula:

Where:

• Breeding Date — Date when the sow was bred
• 114 days — Average gestation period for pigs

3. Importance of Accurate Gestation Calculation

Details: Knowing the expected farrowing date helps in proper sow management, preparing farrowing facilities, and scheduling veterinary care. It also aids in monitoring for overdue pregnancies.

4. Using the Calculator

Tips: Enter the exact breeding date for most accurate results. The calculator will estimate the farrowing date by adding 114 days to the breeding date.

5. Frequently Asked Questions (FAQ)

Q1: Is 114 days exact for all pigs?
A: No, gestation can range from 112-116 days. First-time sows often farrow a day or two later than mature sows.

Q2: What factors affect gestation length?
A: Breed, litter size, season, and parity can slightly influence gestation length. Larger litters tend to be born slightly earlier.

Q3: When should I prepare the farrowing area?
A: Prepare at least 7 days before the estimated farrowing date. Watch for signs like udder development and behavioral changes.

Q4: What if my sow goes past the due date?
A: Consult a veterinarian if gestation exceeds 116 days. Prolonged gestation may indicate problems.

Q5: Can I use this for wild pigs?
A: Yes, domestic and wild pigs have similar gestation periods, though wild pigs may have slightly shorter gestation.
