Research 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 کاملThe effect of the Hurnik-Morris (HM) system on sow reproduction, attrition, and longevity.
Sows were randomly selected and assigned to either the Hurnik-Morris system (HM; n = 59) or a conventional gestation crate system (GC; n = 90) before breeding. The HM system provides housing for sows in small groups. All sows were bred to Duroc x Hampshire commercial boars. A common farrowing barn with 18 farrowing crates was used for the HM and GC sows. The HM sows had less (P<.001) backfat at...
متن کاملHousing options for farrowing: Considerations for animal welfare and economics
Housing systems for farrowing sows have changed very little in the past 30 years. At the mid 20th century, two farrowing environments were common – the outdoor hut in a pasture or lot, and an indoor farrowing pen. The farrowing pens were in low-cost buildings and thus the cost per square foot of building space was relatively low compared to today’s buildings. Farrowing sows indoors has proved t...
متن کاملFeed intake in the multiparous lactating sow: its relationship with reactivity during gestation and tryptophan status.
Voluntary feed intake in sows after parturition may be related to the capacity of the sow to cope with the numerous changes occurring around farrowing. This experiment was undertaken to investigate whether the feed intake during lactation was related to the reactivity of the sow during gestation and plasma Trp and cortisol concentrations. On d 58 of pregnancy, 37 sows were individually placed i...
متن کاملAssessment of a group-housing system for gestating sows: Effects of space allowance and pen size on the incidence of superficial skin lesions, changes in body condition, and farrowing performance
Materials and methods: Pregnant multiparous Yorkshire sows (N = 285) were housed in static groups of 11 to 31 sows in SMALL (34.0 to 49.5 m2) or LARGE pens (72.5 to 74.5 m2) with 2.3 m2 (n = 2,2), 2.8 m2 (n = 3,2) or 3.2 m2 (n = 4,2) per sow. A reference population of 98 sows was housed in gestation stalls. Sows were scored for body condition upon entering and leaving their respective housing t...
