How accurate is the farrowing date provided by the Swine Gestation Calculator?

The calculator provides an estimate based on the standard 114-day gestation period; actual farrowing may occur a few days earlier or later depending on the individual sow and breed.

Can I adjust the gestation period if my pigs have a longer or shorter pregnancy?

Yes, the tool allows you to input a custom gestation period if you know the average for your specific herd or breed, improving the accuracy of the estimate.

Is this tool suitable for all types of pigs, including miniature breeds?

The calculator uses established veterinary timelines for *Sus scrofa*; while the 114-day average is standard, miniature or specialized breeds may have slightly different gestation lengths, so adjust the input accordingly.

What should I do if the calculated farrowing date passes without the pig giving birth?

If the sow has not farrowed by the estimated date, consult a veterinarian to assess the sow's health and determine if induction or further monitoring is needed.
