Types Of Pig Farming In The U.S.

Posted on

Many farmers raise pigs based on of the animal’s life cycle and may not necessarily raise a pig from birth until market all in one barn or on one farm. Today, they are five common types of pig farms in the United States.

Farrow-to-finish farms manage all stages of pig growth and development, from breeding through finishing, to the market weight of about 285 pounds.

Farrow-to-nursery farms specialize in the breeding of sows and raising of 40- to 50-pound feeder pigs, which are then sold to farms that specialize in feeding pigs until they reach market weight.

Farrow-to-wean farms oversee breeding herds and raise pigs until they are weaned at approximately 10 to 15 pounds, at which time they are sold to wean-to-finish farms.

Wean-to-finish farms purchase weaned pigs from farrow-to-wean farms and grow them until they reach market weights.

Finishing farms buy 40 to 50-pound feeder pigs from farrow-to-nursery farms and raise them until they reach market weight.
