1. What is Hog Gestation Period?

The average gestation period for hogs (pigs) is 114 days (3 months, 3 weeks, and 3 days). This calculator helps determine the expected farrowing date based on the breeding date.

2. How Does the Calculator Work?

The calculator uses the standard hog gestation formula:

Where:

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

Explanation: The calculation adds exactly 114 days to the breeding date to estimate the farrowing date.

3. Importance of Accurate Due Date

Details: Knowing the expected farrowing date helps in proper sow management, preparing farrowing facilities, and scheduling veterinary care.

4. Using the Calculator

Tips: Enter the exact breeding date for most accurate results. The calculator will display the expected due date 114 days later.

5. Frequently Asked Questions (FAQ)

Q1: Is 114 days exact for all hogs?
A: While 114 days is average, gestation can range from 112-116 days depending on breed and individual factors.

Q2: How accurate is this calculator?
A: It provides a good estimate based on average gestation. Monitor sows closely as the due date approaches.

Q3: Does litter size affect gestation length?
A: Yes, larger litters tend to have slightly shorter gestation periods.

Q4: What are signs of approaching farrowing?
A: Udder development, restlessness, nest-building behavior, and milk letdown are common signs.

Q5: Should I prepare before the due date?
A: Yes, prepare clean farrowing pens 5-7 days before the expected date and monitor the sow closely.
