The paper describes the evolution of outdoor pig production and points out the main reasons for the growing interest in this system: low capital cost, varying in different situations from 25-70% of those for a conventional intensive system, and lower production cost; growing awareness of animal welfare issues. The most important factors affecting the results of the system, i.e. suitable soil type and climate, skilled stockmanship, are discussed, and an outline of outdoor equipment and management is drawn. The most critical problem of outdoor sow keeping seems to be high piglet mortality. The results of three outdoor units in North - East Italy confirm a great variability of performance, even in the same farm, in different periods. Piglet mortality was very high in critical periods, especially wet and cold weather. Some final considerations about the feasibility and the future importance of outdoor pig production are reported.

Abstract
The paper describes the evolution of outdoor pig production and points out the main reasons for the growing interest in this system: low capital cost, varying in different situations from 25-70% of those for a conventional intensive system, and lower production cost; growing awareness of animal welfare issues. The most important factors affecting the results of the system, i.e. suitable soil type and climate, skilled stockmanship, are discussed, and an outline of outdoor equipment and management is drawn. The most critical problem of outdoor sow keeping seems to be high piglet mortality. The results of three outdoor units in North - East Italy confirm a great variability of performance, even in the same farm, in different periods. Piglet mortality was very high in critical periods, especially wet and cold weather. Some final considerations about the feasibility and the future importance of outdoor pig production are reported.
