Present Welfare Codes recommend systems of dry sow housing which do not involve close confinement. The ‘Pig-code’ system permits automatic individual rationing of group housed sows without the necessity for individual feeding stalls.The computer controlled feed station has a gating system enabling it to be used by two separately housed groups of sows. On entering, each sow is identified by its collar mounted responder and given any feed remaining from the preset amount for that time period.
