Play in pigs is a scientifically validated indicator of positive welfare, with research demonstrating specific play types and conditions that promote its occurrence.
Play science in pigs has transformed our understanding of positive welfare from absence of suffering to presence of positive experience. Pigs that play are pigs experiencing something beyond mere survival: they are engaging with their environment from a position of sufficiency and safety. Designing farming environments that enable and encourage play represents the frontier of positive welfare provision. The practical implications are clear: straw bedding, adequate space, stable social groups, and low chronic stress levels create conditions where play emerges naturally. Farmers who observe and encourage play in their pigs are building relationships with animals experiencing genuine welfare, not merely animals free from acute suffering.
