In order to improve the automation and intelligence level of sows breeding equipment in China,an intelligent and precise feeding equipment for groupbreeding sows is designed,which consists of all mechanical feeding channels,precision feeders and intelligent controllers. The device adopts a small number of feeding ways and a programmable controller as the core controller to collect and store the feeding information of sows. The performance measurement analysis showed that when the single discharge amount was 100 g,the average relative error of the daily discharge amount of the device was 2.59%,the mean coefficient of variation was 2.25%,and the maximum identification radius was 16 cm. The results show that the device has the functions of identifying feeding sows accurately,isolating feeding and precise feeding. The accuracy and stability of feeding and recognition range of the device meet the design requirements.
