Pigs are social1 and intelligent2 animals, who naturally live in family groups3 and are arguably smarter than dogs4. Yet on factory farms, these sentient beings are treated like machines on a production line.

Pregnancy hell

Most pregnant pigs in Australia are confined to lives of chronic suffering in sow stalls. These are small metal and concrete cages that are barely larger than the mother pig’s body; she can’t even turn around.

The science confirms what our common sense tells us: sow stalls cause physical and psychological harm to mother pigs. These devices prevent natural behaviours like exploring and socialising with other pigs,5 and can inflict skin abrasions when sows press up against the metal bars.6 Sow stalls often lead to serious health problems, including reduced bone strength and muscle weight,7 impaired locomotion and severe lameness.8

84%9 of Australian sows spend some of their pregnancy this way, while one third10 are confined for the full 16 weeks of their pregnancy. To give birth they are confined even more restrictively, in a ‘farrowing crate’ that barely allows them to move. Sows are repeatedly impregnated until they no longer produce enough piglets and are killed.11

As other countries take steps to legislate a ban on sow stalls, Australia is lagging shamefully behind. 82% of Australians believe that sow stalls should be banned,12 yet each year we allow around 250,00013 sows to be tormented by these devices.

Piglets

Piglets in factory farms are taken away from their mothers prematurely; a stressful experience that causes a high incidence of clinical disease and diarrhoea.14 Male piglets are routinely castrated without pain relief, a practice so painful that it can provoke trembling and vomiting.15 Piglets’ teeth are often clipped without anaesthetic and this can cause up to 15 days of extreme pain.16

Porkers

Pigs produced for meat on a factory farm generally spend their whole lives indoors. They are housed in crowded, concrete-floored pens with no natural materials. Scientific research proves that some factory-farmed pigs suffer prolonged depression because they are denied natural light, space and the opportunity to forage for food in natural surroundings.17

For many of these pigs, the trip to the slaughterhouse is their only chance to experience life outdoors and to feel the wind and the sun.
