Modern pig hybrids are selected for high daily weight gain within the shortest possible fattening period. In order to meet the consumers’ desire for cheap meat and to consequently keep production costs as low as possible, the equipment in the stables is maximally reduced in space and quality. The design is prioritised towards fattening pigs as cheap as possible, and not according to pig’s basic needs.

The improper housing of the animals leads to stress, and makes the pigs susceptible to disease, which leads to mortality and to an increased use of medication. Common diseases include pneumonia, feet problems and stomach ulcers. After about 160 to 180 days of life, the pig, with a live weight of 110 kg, is ready for slaughter and is sent on his last journey to the slaughterhouse.

As the Landrace breeds became more popular – a breed that gives birth to more piglets that they can care for - the piglets suffer as well. Usually, a sow has 12 teats (14 - 16 is also possible, but not very common), and animals of the Landrace breeds have more than 17 piglets per litter⁷. As a result, more piglets are born with a low birth weight (500 - 700 gram instead of 2 kilos). A sow cannot produce enough milk to support so many piglets, therefore weaker piglets need special care with supplementary milk or with the use of an additional nursing sow⁸. Due to time constraints, this is omitted if mismanagement occurs, and the weak piglets are instead sorted out and – often improperly – killed. 

Behavioural disorders, such as tail and ear biting of other herd members, are the direct consequences of improper keeping and feeding. Instead of adapting the housing conditions to the basic needs of the animals, painful and life-changing interventions are carried out on pigs.

Most common 'solution’ to tail biting is tail docking in week-old piglets, where a hot electrical iron or a scalpel/knife is used to cut or burn off the distal end of the tail, without the use of anaesthesia. The wound is not treated afterwards, and the stressful procedure creates several negative consequences, like acute and chronic pain, as well as the loss of option for natural expression of behaviour.

Pigs use their tails to express their feelings, but they cannot do that if the tail is docked. In the picture above, you can see what different tail movements mean. Learn more about painful mutilations that pigs have to endure to adapt to the production system.

While surgical castration is not routinely practiced in Australia, it remains legal and permitted without pain alleviation by anaesthesia or analgesics. The reason: with intact boars, an unpleasant smell can occur when the meat is heated during cooking. However, boar taint is very rare, and occurs mainly if animals are kept in inappropriate husbandry and hygiene conditions. Fortunately, there are chemical alternatives to surgical castration like immunocastration and vaccinations.

Breeding sows have to give birth to as many piglets as possible and as often as possible, with fatal consequences for their health: an average of 50 percent of sows have to be prematurely sorted out and slaughtered annually due to fertility problems and health problems. 

A breeding sow who is nursing her piglets for half of her production life, is squeezed into a narrow metal cage during this time. This cage is only as big as the sow itself – she cannot turn around. Breeding sows are fixed in this crate to reduce the number of crushed piglets, due to insufficient space and a lack of nesting material. There are kinder alternatives to sow stalls, such as free-farrowing stall, as used e.g. in organic or outdoor systems. Learn more about the problems with sow stalls and farrowing crates.

They are inducing fear, pain, and distress, thus diminishing the immune system, altering brain function and the natural behaviour of animals.

• General ban on keeping sows in crates, across all countries. There are many animal-friendly alternatives to this, and the system should be adapted to the animal and not vice versa.
• Free farrowing systems (with protection against piglet crushing) in which the sow can build a nest, move, and turn around, as well as socialise with her piglets and conspecifics.
• Limitation of an individual fixation to an absolute minimum (by the hour), e.g. for treatment purposes and veterinary interventions only.
• Ban (and more enforcement measures) on the painful mutilation procedures, like tail-docking and un-anaesthetised castration.
• Highly intensive concentrate feeding must be avoided.
• Fully slatted flooring should not be allowed.
• Ban on breeding for extreme performance (e.g. for more teats per sow) - the well-being of the animal must be prioritised and the average number of piglets per litter must not exceed the number of teats.

if neglected it leads to poor welfare states and therefore to suffering, acute pain, distress, fear, and long-term negative welfare states. Basic needs of pigs are:

• Pigs are a social species and must be kept in stable and appropriate groups – group keeping of sows and group farrowing should be a standard procedure. If group farrowing is not possible due to management reasons: temporary individual farrowing in movement bays (max. ten days) with protective devices (piglet deflectors) to prevent the piglet being crushed. After that, group reunification should occur, as it can be otherwise highly detrimental to their health.
• Long straw should be always available as nesting material in the farrowing area in the days before birth
• Pigs have a strong motivation for foraging, that’s ideally taking up most of their time budget in a day. Rooting is one of the most prominent and important part of foraging behaviour and not being able to fulfil it, results in many different health issues (e.g. stereotypies).
• A diet, appropriate for pigs (with high fibre and forage content), is not only essential for maintaining their physical health (prevents the nowadays frequent stomach ulcers), but also gives them the possibility to express their natural foraging behaviour.
• Sufficient lying space with dry and soft bedding is crucial – hard surfaces cause shoulder sores for the sows (due to their weight causing pressure on the shoulders and spine), and open wounds on joints in piglets (due to them constantly kneeling down to suckle).
• Appropriate soft flooring - pigs' claws are adapted to soft and swampy floor - hard floor surfaces cause feet problems, lameness, and bursitis
• Access to the outdoor area should be readily available, where the animals can experience the outside world and enrich their life – the animals are less bored and in control of their daily life, when they can experience different environments.
• The shelter should give protection from extreme weather conditions and have good air quality, with readily available water and food.
• Animals should be kept in good health and receive veterinary care if needed.
