31What are the different production systems and how do they work? TermsFarrowingprocess of a female pig giving birthFeeder pigsa pig that has been weaned and weighs approximately 40 pounds
32Sow and Litter SystemsPigs are farrowed and fed up to slaughter weight at the same farmconfinement or pasture systemsmost common swine operations
33Sow and Litter Systems Confinement Advantages pigs can be marketed throughout the yearless laborincome throughout the yearDisadvantageexpensive startup costsPastureAdvantagelower initial investmentDisadvantagesmore labor intenseproduction might be limited depending on season
35Purebred SystemProduces breeding stock that others producers will use in their systemsRequires intense managementregistration paperworkLeast common operationLess than 1% of all hogs raised in the U.S. are registered purebredsPurebreds are extremely important because of breed improvements
36Purebred Systems To be a purebred producer you must know: a great deal about geneticsshowing & promotion of your breedPurebred Producers are working to:create animals that will meet consumer demands
37Feeder Pig Production System Breed & farrow litters of pigletsThis systems farrows and weans and sells the feeder pigsKeeps a breeding herd of sows that farrow between 14 to 16 piglets eachMinimal investment is requiredMust mange to keep a steady supply of feeder pigs to sellLess feed is required in this system
39Finishing Feeder-Pig System Operations that buy feeder pigs and feed them until they are market weight approximately 240 poundsProfit is based upon how much feed it takes to produce 1 pound of porkThe less feed it takes the more profitBalancing feed rations is very important in this system
