Standard pen crated sow 1 2 Side 3
Dimensions 1 2 Sow: A. Crate length 210 cm B. Trough: 40 cm from front to back E B Piglets: C. distance needed for suckling 125 cm D. 1 m 2 solid floor E. Covered creep area: 0,8 m 2 D C A Pen length: 270 cm 15 cm from crate gate to pen gate Side 4
Solid floor under sow and piglets 1 2 + slatted floor along the pen wall + covered piglet area + solid floor under sow and piglets Prefab floor elements Side 5
Ensure the thermal needs of the piglets Heated barn Correct regulation of heating pads, heated floor and heat lamps / panels Insulation of covered creep area equals 1½ cm of mineral wool 1 2 Give special attention to: Creep areas facing aisle pen walls and floor mats Use insulated mats Side 6
Floor cooling - not a standard recommendation 1 2 No signifikant effect Feed consumption Weaning weight Weaned per litter Passive cooling Insulated roof Active cooling Air cooling Side 7
Nesting, rooting and enrichment 1 2 Side 8
Prevent spillage 1 2 Side 9
Easy emptying of the trough 1 2 Tilting the trough Water vaccum cleaner Side 10
Working environment Easy access to pen 1 2 Saloon-gate Side 11
Working environment Access from 2 sides 1 2 Side 12
What should be improved by 2016? Even better handling of large litters (split suckling, heating of slatted floor at farrowing, better water supply..) Good hygiene Remove feed/water spillage Prevent spillage Good hygiene Avoid the need for environmental technology Improve thermal environment for the piglets Side 13
Computer-based dry feeding less spillage few troughs to empty 1 6 Side 14
Improved flooring system 1 6 Side 15
Devided pit with spot extraction 1 6 Side 16
Heated slatted floor at farrowing 1 6 Side 17
Coping with large litters 1 6 Special pen design for sows with the smallest piglets? Split suckling during entire lactation period? Side 18
Easy split suckling 1 6 Advantages: Space for suckling Challenges Catching piglets Requires more space Side 19
Prevent spreading of diarrhea 2 0 Side 20
Conclusion pens with crates 2012 2016 2020 Improved flooring Improved thermal environment Improved working environment 2012, ver. 2 Improved coping with large litters 2016 ver. 2 loose sow? Side 21

The aims of loose housing of lactating sows are: THEME First movers 12-16-20 High welfare for the sows High milk uptake for the piglets High neonatal piglet survival rate High level of motivation for staff High level of acceptance from the society So the pens build shall fulfill these aims! Side 23
Conditions : Ministry of Justice Housing of pigs 11-16-20 1 1 Crates will be prohibited in the long run Transition period loose housing volontarily In 10 years 10 pct. loose housed Side 24
12-16-20 1 1 10 % in 10 years how do we get there? App. ¼ lactating If app.10 % loose If 1.200 sows/herd 1,2 million sows 300.000 crates 30.000 pens 100 herds? Today we have equivalent to app. 4-6 herds Side 25
2012 Two tracks Loose farrowing sows no optional crate We have the pen but we need more herds and more experience Optional crate (Swing-side) The best pen today has drained/fully slatted floor Initiate the project The sow is loose as much as possible Joint project with University of Copenhagen 1 2 For both tracks we focus on: Pen- and barn design Management Climatic conditions and environmental impact Neonatal survival Level of productivity Side 26

Farrowing pen with an optional crate As long as the crate is used, the sow eat and defaecate in the same position When the crate is opened, the sow continues to get fed in the trough 1 2 But the sow turns away from the trough when defaecating This pen is flexible regarding the use of the optional crate BUT we need it to be flexible to in regard to Floor/surface/slats Side Position of feed/trough 30

The sow is loose as much as possible - new project in collaboration with LIFE The potential impact of crate on the sow behaviour Change from loose to crate Stressmeasures Behaviour Farrowing The impact on piglet survival of using a crate Stillborn Neonatal survival until weaning The impact on staff/work conditions of an optional crate Work conditions Strategy for when to use the crate 1 2 Side 32
2012: Prepared for the future? - No guarantee, but there are options 1 2 Side 33
2016 1 6 Two tracks Loose farrowing sows nocrate Increase in number of full scale herds, experience and knowledge The sow is loose as much as possible The influence of the crate on nest building, farrowing, and behaviour in the first few days post farrowing for sow, piglets and staff In collaboration with University of Copenhagen Both pens have been developed in regard too: Pen- and barn design Management Climatic conditions and environmental impact Neonatal piglet survival Level of productivity Side 34
Pen loose farrowing sow 1 6 We ve made significant progress regarding management, production level and ressource use Climatic condition eg. Floorheating and -cooling Temperature Air outlet through the floor Daily work routines eg. Nursing sows Getting familiar with the pen Feeding Automatic detection of High risc sows Piglets/litters at risk Side 35
