Enriching the barren lives of factory-farmed pigs
Pigs on factory farms become bored and frustrated. As well as needing to be free from cages, they need enrichment such as straw to explore and allow them to express their natural behaviours.
Factory-farmed pigs still retain their range of wild behaviours, and naturally they would spend around 25% of their day foraging or rooting around for food. Enrichment is also important for piglets as part of playing, learning and adapting to life as they grow.
Strong sense of smell
As smell is their keenest sense, pigs naturally use their noses to explore their environment for food. They’re always keen to smell, feel and chew anything possible, yet there’s little to satisfy this need in a barren concrete pen.
This lack of enrichment brings on stress, boredom, and frustration, which leads to abnormal repetitive behaviours. Just like a pacing tiger or swaying elephant in a zoo, pigs develop repetitive behaviours too, indicative of their daily stress and deprived natural behaviours.
Pigs also ‘sham chew’ – repetitive chewing with no food – or bite bars, tails or other parts of other pigs. This can lead to injury, fighting, infection and even death.
Enrichment is vital
Enrichment is an essential, practical solution which enables pigs to be pigs.
Enrichment can be any safe material that stimulates and encourages natural behaviours. Straw bedding is a great form of enrichment, and allows for exploration, comfort and additional fibre to eat.
Working with farmers and producers
In some countries, straw is not easily available or safe, so farmers need to innovate and use other local materials.
We convey the important aspects of enrichment to farmers and producers: for example, materials must be enticing and chewable, and ideally edible. We also provide tips for placement, location and regular rotation of enrichment materials to keep pigs interested.
Farmers can trial various materials they can sustainably access. For example, some farmers in Asia use rice hulls or sand for bedding, edible grasses, branches, wood, cabbages, coconut husks, natural ropes and sacks. They can also provide chewable ‘toys’ – some can be similar to the ones your dog loves!
A life worth living
So, as we enrich our daily lives in ways that matter to us, we need to remember what matters to pigs. Join us as we call on farmers and producers to provide enrichment for factory-farmed pigs.
It doesn’t matter if they are pregnant mothers in a group or nesting prior to giving birth, curious growing pigs or male breeders. All pigs need to forage, explore and satisfy their natural behaviours.
