Pregnant sows are generally kept tethered or confined in individual stalls in order to reduce aggression. When such a housing method is adopted, many effects contrary to the welfare of animals arise (Fraser, 1975; Stolba et al., 1983). In Italy, even in intensive breeding units, sows are kept in groups for at least half of the pregnancy, without great problems of productivity. In this study, we show the results of an investigation carried out in order to detect when and where the aggression occurs among grouped sows, with special reference to the feeding method.

Abstract
Pregnant sows are generally kept tethered or confined in individual stalls in order to reduce aggression. When such a housing method is adopted, many effects contrary to the welfare of animals arise (Fraser, 1975; Stolba et al., 1983). In Italy, even in intensive breeding units, sows are kept in groups for at least half of the pregnancy, without great problems of productivity. In this study, we show the results of an investigation carried out in order to detect when and where the aggression occurs among grouped sows, with special reference to the feeding method.| File | Dimensione | Formato | |
