Increased social interactions and support from sounders also reduces the rate of savaging and piglet-directed aggression, indicating that would be beneficial to raise pigs in a free-roaming environment, but further research is needed to indicate if this would be economically feasible. Restlessness and aggressive behaviour prior to farrowing have been shown to predict savaging and piglet-directed aggression following farrowing, allowing for the identification of individuals prone to savaging and subsequent treatment, precautionary measures, or supervision.
Higher social interactions and support from sounders reduce savaging and piglet-directed aggression rates. This indicates that raising pigs in a free-roaming environment could be beneficial but more research is required to assess its economic viability. Restlessness and aggressive behavior before farrowing are associated with increased savaging and piglet-directed aggression after farrowing, facilitating the identification of individuals prone to savaging and subsequent treatment, precautionary measures, or supervision.
