Others are simply left to suffer and die on their own. Male chicks born in the egg industry are considered merely a wasteful byproduct. Since they can't produce eggs, newly hatched males are crushed to death and used for fertilizer and as feed. Goat farming is becoming increasingly industrialized, and more and more goats are being genetically manipulated and intensively confined. Goats have their throats slit in front of others, often with dull blades.
Pigs spend their entire lives in cramped, narrow stalls.
Crowded to the point where they can barely turn around, they sometimes take out their frustrations by cannibalizing each others' tails. Pigs are often killed by being beaten with hammers or having hot iron rods pushed up their anuses. Others are stabbed with 20 or more small knives so that the blood runs out slowly, because farmers believe this makes the meat more tender. This overcrowding causes injuries to the snouts and fins of fish and puts abnormal stress on them, leading to outbreaks of disease. So aquafarmers pump the fish full of antibiotics and chemicals to control parasites, skin and gill infections, and other diseases common to farmed fish.
