Abstract Background The natural feeding behaviour of the pig is searching for feed by rooting activities throughout the day self-feeding pigs randomly space their eating and drinking periods throughout the day consuming ten to twelve meals per day. Pigs in conventional fattening pig production are normally fed 2-3 times daily with the feed consumed within 15 minutes. The aim of this study was to determine if more frequent feedings could improve the performance of conventionally kept fattening pigs. Methods The experiment was carried out on 360 fattening pigs 27-112 kg live weight weighed and assigned to pens stratified by weight and sex. Each treatment group consisted of 180 pigs allocated to 20 pens with nine pigs in each pen. To evaluate how more feeding occasions affects performance and
