From Wikipedia, the free encyclopedia
Intensive piggeries (or hog lots) are a type of factory farm specialized for the raising of domestic pigs up to slaughter weight. In this system of pig production, grower pigs are housed indoors in group-housing or straw-lined sheds, whilst pregnant sows are confined in sow stalls (gestation crates) and give birth in farrowing crates.
The use of sow stalls for pregnant sows has resulted in lower birth production costs, however, this practice has led to more significant animal welfare concerns. Many of the world’s largest producers of pigs (U.S., Canada, Denmark) use sow stalls, but some nations (e.g., the UK) and some US States (e.g., Florida and Arizona) have banned them.
