System and method for gestation of sows in large pen gestation facilities

摘要

A sow management system makes use of separate Trickle Feeding and loafing areas separated by a one way gate or gates to establish a general continuous flow of sows through an interrogator apparatus where an RFID tag for each sow is read to determine if such sow should be returned to the general Trickle Feeding area or at least two other possible areas through automatic gating controlled by computer means sensitive to RFID tagging of the sows.
