2. Outline for Sow Housing Seminar Objectives of the seminarBrief description of the main types of group-housingsystemsGeneral factors involved with deciding which group-housing system to useOverview of retrofitting projectRetrofitting an existing individual stall gestationfacility into: Electronic sow feeding facility Short-stall feeding facilityComparison between ESF and short-stall system2 3. Sow-group housing systems Noncompetitive feeding system Electronic sow feeder Free-access stalls (self or caretaker locked) Cafeteria feeding with lockable feeding stall Competitive feeding systems Short feeding stalls (Trickle feeding; Traditional dropbox) Full-body length stalls (non-lockable) Floor feeding3 4. Electronic sow feeder (ESF) system4Photo: Jeff Schoening / APResting baySows enterSortsowsWaterSortalleyProtectedfeederFeeddeliveryThis specific system:Feeds up to 80 sows per stationFeed two different diets & top dressTo establish a day for the sows, feeder isclosed 4 to 6 hours per 24-hour period 5.

Choosing a group-housing system involves: Investment costs Ability of housing system and management to maintain ahigh level of the sows health and welfare Ease of performing daily management practices Labor requirement and availability of skilled labor Feeding system (major factor to consider) Competitive while eating Non-competitive while eating Method of housing (static vs dynamic) Reproductive performance Overall simplicity of the system Not one system fits all situations13 14. Overview of remodel project 2,500-sow unit Goal is to produce 1,000 weaned pigs per week Farrowing ~108 sows per week Breeding 120 per week Breeding-gestation facility 79 ft wide x 492 ft long (interior dimensions) 4 cross-over alleys 720 breeding-gestation stalls (2 ft x 7 ft) 1192 gestation stalls (2 ft x 7 ft) 239 stalls per row; 8 rows of stalls Partially slatted floor14 15. 36" feed alley36" feed alley36"alley36" feed alley36" feed alley36" feed alley7277777732227333339.539.515 16. BEFOREAFTERCourtesy of APTypical floor plan for a partially slattedbreeding-gestation stall building. Howcan this facility be modified for use witha group-housing system that uses ESF orshort-length feeding stalls? Is the raisedfeeding alley a problem?Overview of remodel project16 17. Factors to consider when remodeling Feeding/Housing System Stay within the present building shell or expand Work with the present feeding system Floor space allocation per sow Number of sows per pen #Boar pens Size and configuration of relief space Number of relief spaces17 18. Nutritional Care of Group-Housed Sows Electronic Sow Feeding Specify amount of feed offered to each sow eachday Can modify diet fed Can change daily feed intake based on bodycondition, body size and stage of gestation Provides a daily report that indicates which sows didnot completely eat their previous days allotment offeed or did not eat any feed. Potential feed savings18Feeding method with most control of dailyfeed intake and diet 19. Nutritional Care of Group-Housed Sows Short-length, non-gated feeding stalls Allocate feed volume to average body weight ofsows in the pen? Use of multiple pens for the same breeding groupcan improve feed allocation requirements per pen(body weight; body condition score)GiltsSmall & thin sowsBig Sows19Feeding method with partial control ofdaily feed intake and diet 20. Nutritional Care of Group-Housed SowsIn any competitive feeding system, dominant sow(s)have opportunity to steal feed from other sows.
