1 The majority of pigs today are raised in total confinement Swine HousingThe majority of pigs today are raised in total confinement
2 Confinement Production What are some of the advantages and disadvantages of raising swine in confinement?
3 Advantages Less labor per cwt of pork produced A more stable environmentFewer parasitesLess disease problemsIncreased productivity
4 Disadvantages Buildings and equipment are very expensive Energy costs Reproductive problemsWaste disposal
5 Waste HandlingManure disposal is a critical part of raising pigs in total confinement (3-4 T/200 lb hog/yr.Typical methods of handling waste in confinement buildings include:Gutter flush to a lagoonManure pitMechanical scraper
7 Farrowing FacilitiesIn the past individual farrowing houses were quite common when sows and pigs were raised on pastureToday most farrowing houses are ‘central’ in design.Central farrowing houses consist of one or more rooms that accommodate groups of sows
8 Farrowing House Continued Most producers use farrowing cratesYears ago the majority of sows were kept in individual pens prior to and after farrowingCrates are preferred today because they result in more pigs weaned per litter
9 Nursery FacilitiesNursery barns often contain several rooms with each room designed to accommodate the number of pigs from an individual farrowing roomSmall pens designed to handle 6 to 8 pigs are very common although some pens may be large enough to handle 16 to 25 pigs
10 Nursery Building Continued The facilities are designed to provide a fairly stable environmentThese facilities may be designed to accommodate 3 week old pigs or perhaps 10 d old pigsSupplemental heat is provided via heat lamps, radiant heaters or perhaps heat in the floor
11 Grow-Finish Facilities Environmentally enclosed (totally enclosed) buildings are the most popular todayOpen-front buildings popular in the 60sModified open front (MOF) buildings were popular in the 80sHoop buildings are the most recentSpace requirements of 8-10 sq.ft./hd for G-F
12 Waterers Nipple waterers are very popular in confinement Water cups are also popularSome buildings (particularly gestation buildings) may use a concrete feed trough as a place to provide water after feedingRule-of-thumb = provide one waterer/15 pigs
13 Feeding EquipmentSelf feeders are generally used for nursery and grow-finish pigsBreeding stock are generally limit fed via floor feeding or in self feedersPigs per feeder space range from 2 for nursery pigs to 4-5 for finishing pigs.
14 Terms you should know Segregated early weaning (SEW) Split-sex feeding Phase feedingMultiple-site systemsAll-in-all-out (AIAO)
15 Terms definedSEW = refers to weaning the pigs at days of age when they are still protected from diseases via passive immunity from the mother’s milk. These pigs are removed from the sow and placed in a separate building.
16 Terms continuedSplit-sex feeding = refers to feeding gilts and barrows separate since gilts are normally leaner than barrows and as a result have a higher protein requirement.Phase Feeding = refers to frequent changes in the diet to more closely meet the specific nutrient requirements for various weight groups.
17 Terms continuedMultiple-site systems = generally refers to having a different location for breeding-gestation-farrowing versus nursery versus grower-finishing.AIAO = refers to a management system where all animals from a particular building or room are moved in and out on the same day.
