Pigs are highly social animals with established dominance hierarchies. Managing social groups appropriately reduces aggression, improves welfare, and minimises injuries to ears, tails, and flanks.
Newly mixed pigs fight to establish dominance — this is normal but its severity depends on management. Inadequate space forces pigs into confrontation rather than allowing retreat. Multiple resource points prevent monopolisation by dominant individuals. Good social management reduces injuries, improves growth rates, and generates better welfare outcomes for every individual in the group.
