Pig Outdoor Systems - Summer Welfare

Welfare challenges and solutions for outdoor pig systems during hot summer weather, including wallow provision and shade.

Key Facts

Pigs cannot sweat and regulate body temperature through rooting, wallowing, and seeking shade
Wallows reduce pig body temperature by 3-4 degrees Celsius through evaporative cooling
Shade provision via artificial covers reduces heat stress when natural shade is unavailable
Outdoor pigs in summer require wallow refreshing every 1-2 days to maintain cooling function
Heat stress in sows reduces conception rates and increases early embryonic mortality
