REVIEW: Compilation of the Scientific Literature Comparing Housing Systems for Gestating Sows and Gilts Using Measures of Physiology, Behavior, Performance, and Health
The objective of this review was twofold. First, a series of meta-analyses (analyses of treatment effects across studies) were performed on available data from scientific literature to determine whether sow behavior, performance, or physiology differed for sows in group pens or individual stalls. Second, research publications in areas of performance and health, physiology, and behavior of pregn...

متن کاملResearch on Group-Housing for Sows
Sow housing is a controversy issue in the swine industry. The conventional confinement housing system for sows, such as gestation stalls and farrowing crates have been used in the western countries for more than 30 years. Despite the advantages of confinement sow housing systems, concern over sow welfare due to restriction of movement has resulted in gestation stalls being banned in the Europea...
متن کاملAlternative Sow Housing Systems : Driven by legislation , regulation , free trade and free market systems ( but not science )
Sow housing in the broadest sense refers to how sows are kept. Sows may be kept indoors or outdoors in a variety of systems. Penning with indoor or outdoor systems differ substantially. Outdoors, sows are almost never kept in crates or stalls but rather in pens or pastures of various sizes that allow social grouping. Indoors, sows may be kept in individual crates, stalls or tethers or in pens o...
متن کاملEvaluating Housing Stress in Gestating Gilts Using Immunological Measures
Although gestation stalls have provided a reduction in building and labor costs to producers, they remain a controversial system of swine production in terms of animal welfare. Gestation stalls physically limit the sow to standing, sitting, and lying. Several studies have suggested that repetitive abnormal behaviors, termed stereotypic and considered an indicator of poor welfare, can be induced...
