what is a gestation crate
Gestation crates, used on modern pig-production facilities, commonly referred to as factory farms. A gestation crate, also known as a sow stall, is a metal enclosure used in intensive pig farming, in which a female breeding pig (sow) may be kept during pregnancy and for most of her adult life. The enclosures measure 6.6 ft x 2.0 ft (2 m x 60 cm).
