Última Behaviour of pre-parturient sows housed in intensive outdoor or indoor systems PAB Hötzel,Maria José; Machado Filho,Luiz Carlos Pinheiro; Dalla Costa,Osmar Antônio. This work compared the behaviour of pre-parturient sows housed in intensive confined and outdoor systems, during the morning and afternoon prior to delivery. Eight sows were kept individually in farrowing crates or in paddocks with access to fresh pasture from 8 to 10 days before expected parturition. All outdoor sows built a nest within 24 hours before farrowing. On the morning and afternoon before farrowing they spent 6.5% of the time collecting grass and 7.5% of the time organizing the nest. Outdoor sows were observed more often than confined sows rooting (4.60% vs. 0.25%), feeding (10.2% vs. 3.0%), standing (51% vs. 13%) and walking (8% vs. 0%). Indoor sows redirected the nesting behaviour to other behaviours like attempts to dig the ground, nosing,...

To mitigate odor and gas emission concern, different management practices and treatment technologies are available. In this study, the effectiveness of the Digest3+3© microbial additive was evaluated for reducing odor and pollutant gas emission from a swine gestation-farrowing operation in North Dakota.  In this experiment, one of the deep pits in the facility was left untreated (GC) and the other deep pit was treated (GT) with the Digest 3+3 (22.68 kg/month).  Similarly, shallow pits in one of the farrowing units were treated (FT) with the microbial additive, while another unit was untreated (FC as the control).  Air samples were collected from exhaust fans using a vacuum chamber and Tedlar bags.  Odor detection threshold values were determined using a...

Ano: 2011 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/1940 Natural ventilation and surface temperature distribution of piglet crate heated floors Arq. Bras. Med. Vet. Zootec. Mendes,A.S.; Moura,D.J.; Nääs,I.A.; Bender,J.R.. This research had the objective of evaluating the influence of the natural ventilation on the surface temperature distribution of heated crates. The research used six crates from a farrowing room in a commercial swine production farm located in the state of São Paulo, Brazil. Three crates were heated using a heat mat while the other three had the environment heated by incandescent light bulbs (200W) fixed on the lateral wall. The surface temperature of the crate's floor (1.55x0.55m) was registered in 36 points, distributed in 18 quadrants (0.26x0.18m) using an infrared thermometer in three different conditions of the room's natural ventilation: opened, semi-opened, and closed lateral curtain. The isotherms and the temperature distribution of the floor heat... Tipo: Info:eu-repo/semantics/article Palavras-chave: Thermal comfort; Air velocity; Farrowing; Swine.
