Forty-four sows and litters were housed during lactation in either (1) a `confined' pen (× m) where the sow and litter were kept together (n=17), or (2) a `get-away' pen (× m), where the sow could leave the litter at will by stepping over a barrier (n=27). Each get-away pen consisted of a `nest area' (× m), and a `piglet-free area' (× m).Cited by: The assessment of welfare within farrowing systems presents a unique challenge for pork producers, veterinarians, and animal scientists. Welfare assessment within all other phases of swine production involves pigs at a single stage of their productive life. Within the farrowing environment, the sow and her piglets are at two very different stages of their life, and have different requirements. suckling and rearing pen is normally used. The sow is brought to this pen one week before farrowing and stays there together with her litter for 5 to 8 weeks when the piglets are weaned by removing the sow. The sow is often confined in a farrowing crate a few days before, and up . It is very important to realise that the temperature and environment requirements of the sow and her litter are different. The sow likes it cool, but the piglets need all the warmth they can get. It is desirable to provide them with a ‘creep’ i.e. a closed shelter like dog kennel with a removable lid to allow easy cleaning and observation.
to $ per sow place. Labour costs may be 20% to 30% higher in DLH systems because bedding needs to be added and spent litter needs to be removed. Benefits of deep-litter housing (DLH) • Capital costs are reduced by 60% to 70%. • Construction costs are lower through the use of large group pen kit shelters or converted skillion-style hay sheds. For two-and-a-half years, the effects of two gestation housing systems on sow and litter performance were evaluated in a project at an ISU-managed research farm owned by the Wallace Foundation for Rural Research and Development in southwest Iowa. One system involved individual gestation stalls in a mechanically ventilated confinement building. The downside of group housing is dealing with sow aggression. Planning ahead and carefully assembling groups helps minimize problems, Davis says. Hord Livestock groups gilts together and fills in as needed with young sows that have had one litter. Older sows are assembled in “like minded, like sized” groups, he says. The modern hyper-prolific sow gives birth to more piglets than she has functional teats (in the following called supernumerary piglets). The aim of the present study was (1) to investigate the production consequences of hyper-prolific sows rearing supernumerary piglets equal to the mean live-born litter size, and (2) investigate whether potential negative effects on survival and growth could.
Most pigs in the world used for pork production are kept on commercial farms using an indoor sow housing system. The most common method of housing the breeding sow is in a crate or pen (Figure 1, right). The breeding crate is large enough (often m × m) to accommodate the body of the sow but the breeding crate does not allow the sow to turn around or to express her full repertoire of . By Flemming Thorup, DVM, Senior Scientist, SEGES Pig Production, Livestock Innovation, [email protected] Abstract Managing a sow with less piglets than milk glands is simple. When the number of piglets at the sow exceeds the number of milk glands, you need to improve your management. Management in the farrowing unit can be divided into 4 parts. Taking care of small new born piglets Adjusting litter. As a result, it’s hard to accurately predict the success of any one group housing system. There are examples of good and bad transitions. Focus on these key features to increase your chances of success with group sow housing. Floor space allocation for sows; Feeding plans to control changes in sow .
