Health and welfare problems of pigs in intensive husbandry systems are mainly caused by housing and management of the animals. The actual structure of these systems also gives rise to health and welfare problems. Solving these problems is very difficult to achieve in the existing systems. It will be necessary to create new structures and housing systems from a preventive veterinary point of view to avoid harm to health and welfare caused by specific stressors. Specific stressors which can be prevented are associated with the risk of infection, mixing and replacing animals, high density, inadequate house climate, handling of animals and the farmer's attitude towards his animals. The SSF-system specifies the method by which these specific stressors are prevented.
集约化养殖系统中猪的健康和福利问题主要由动物的饲养和管理方式引起。这些系统的实际结构也会引发健康和福利问题。在现有系统中解决这些问题非常困难。有必要从预防性兽医的角度创建新的结构和饲养系统，以避免特定应激源对健康和福利造成损害。可以预防的特定应激源与感染风险、动物混群和替换、高密度、畜舍气候不佳、动物处理以及农民对其动物的态度有关。SSF系统规定了预防这些特定应激源的方法。
