Abstract

The study was conducted to develop an ESF (electronic sow feeder) for improving animal welfare of group housed gestation sows. Feed intake of both individual and group housed gestation sows was restricted 2 kg a day. ESF system was very effective in reducing feed loss. The amount of feed loss in treatment group (group housed gestation sows with ESF) was only about 55 g, while the amount of feed loss in control group (individually housed gestation sows) was about 200 g. In spend time to feed intake, there was no difference in the result between the control (about 30 min) and the treatment (about 22 min) group. The ESF system ran well without any mechanical problems throughout the entire experiment. These results suggest that the EST is expected to improve the performance feeding of sows.
