Gestation crates for pigs are typically about two feet wide and prevent sows from turning around, maximizing use of available space. Some producers say it also prevents the pigs from harming one another. Breeding pigs can produce seven or more piglets per litter, totaling well over 60 piglets in consecutive pregnancies over a few years. Widespread use of gestation crates began in the 1970s as pork producers gave priority to efficiency. A 1978 article in the industry publication National Hog Farmer suggested producers consider the sow “a valuable piece of machinery whose function is to pump out baby pigs like a sausage machine.”
“Under that mind-set, the industry went, no pun intended, hog wild into moving pigs into gestation crates,” says Matthew Prescott, senior director of food and agriculture for the Humane Society, who has been focused on eliminating the crates since 2002.
