They also need a method to identify all sows. Gestation based on 114-day gestation time. 1 Farrowing dates for other breeding dates can be easily interpolated. For example, a sow bred November 6 will farrow March 1. However, producers should be ready for delivery prior to the due date because of individual variation in gestation.
Newborn pigs have a better survival chance if they arrive in a clean, sanitized farrowing facility.
In addition, most producers feel that a break between farrowing reduces disease buildup. Many producers, however, farrow continuously to maximize use of expensive facilities. They must do a top job of cleaning and sanitizing. A steam cleaner or high-pressure sprayer can be used successfully to clean the farrowing house. Adding a detergent helps remove organic matter.
