At weaning, sows are moved from the farrowing facilities to pens or stalls near the breeding area in preparation for mating. The recovery period usually takes around 6 days and during this time, mammary involution occurs, and endocrine function changes to initiate follicle growth on the ovaries.

The sow's nutritional requirements change becuase there is no longer a requirement for milk synthesis.
