What is extensive system of pig production?

Extensive system of pig production refers to a farming approach where pigs are raised in larger outdoor areas, allowing them to roam and exhibit natural behaviors. This method typically involves lower stocking densities, relies more on pasture or forage, and often requires less intensive management compared to intensive systems. While it may yield lower production rates, extensive systems are often seen as more sustainable and animal welfare-friendly. Additionally, they can have reduced environmental impacts compared to conventional pig farming practices.
