About this calculator
Overview
The '3-3-3' Rule: Pig gestation is famously consistent at 3 months, 3 weeks, and 3 days (114 days). While modern genetics can vary slightly (112-116 days), 114 days remains the gold standard for prediction.

Pro Tips
Move to Crate: Sows should be moved to farrowing crates/pens on Day 109 to acclimate.
Temperature: Sows prefer cool (60-65°F), while newborn piglets need heat (90-95°F). Use heat lamps/mats for piglets.
Assistance: If more than 20-30 mins pass between piglets, manual assistance may be required.
Colostrum: Piglets must nurse within 6 hours to receive vital antibodies.

Fun Facts
"Sows 'sing' or grunt rhythmically to their piglets while nursing to coordinate milk letdown."
"A healthy sow can nurse a litter of 12-14 piglets on her ~14 teats."
"Piglets are born with 8 sharp 'needle teeth' which fight for teat dominance."
"Pigs are highly intelligent, ranking close to dolphins and chimpanzees in cognitive tests."
Formula: Farrowing Date = Breeding Date + 114 Days
