Gestation Calendar

HOW TO USE THE GESTATION CALENDAR

Each set of two columns represents two dates. The left side is the date bred and the right side (directly across) represents the date 112 days after breeding, when sows are usually moved to farrowing. Farrowing normally occurs 114 to 115 days after breeding.

EXAMPLE: DATE BRED - April 4, MOVE TO FARROW DATE - July 25.

DATE BRED: JANUARY 1 - JUNE 30
