　　The study was conducted to develop electrical sow feeding (ESF) system for improving animal welfare of group housed sows.They were fed daily at a level of 2kg using automatic feeding system.The period of each feeding was set at about 20 minutes.The maximum possible number of sows fed by ESF system was around 45 heads.The ESF system ran well without any mechanical problems throughout the entire experiment.Feed intake of both individual and group housed sows showed similar range (below 2kg).ESF system was very effective in reducing feed loss.The amount of feed loss of ESF system was only 100g, while individually housed sows showed about 700g feed loss.About 85% of sows took feed once a day with ESF system.However the individually housed sows took it 2-3 times a day.
