Pig farrowing crates are barred metal crates within a pen where pregnant sows are placed shortly before giving birth. Farrowing crates prevent the sows from turning around and only allow them to move a little forward and backwards.
Alongside the farrowing crate, within the pen, there is an area called a “creep” that the sow’s piglets can move into. This is often heated to attract the piglets from lying next to the sow. The piglets are still able to reach the sow’s teats to suckle but when they are in the creep, she is prevented from being able to clean or interact with them.
After giving birth to piglets, there is a possibility that the sow will crush them. A fully-grown sow can weigh around 300kg, a piglet, on the other hand, weighs just one to two kg. So, if the sow accidentally steps or even lies down on one of her newly born piglets, she can injure or even kill them.
The bars of the farrowing crate are placed so that the piglets can escape underneath them when the sow stands up and lies down, reducing the risk of them being harmed.
When the sow lies down to rest or to suckle her young, she may inadvertently crush one of them due to her large size in comparison with the piglets, and the difficulty she has in lying down slowly and gently.
Farrowing crates make for a more economical way of keeping farrowing sows indoors since they take up less space than farrowing pens that allow sows to move freely during and after giving birth. It is also easier for farmers to look after the sows without fear of being injured by a mother protecting her young. Farrowing crates are also thought to reduce the possibility of accidental piglet mortality and hence increase production and economic return, though this is not always the case.
Farrowing crates are a major concern because they provide so little space, preventing sows from being able to turn around freely and build their nests. Even if nest building material is provided, which it sometimes isn’t, they do not have room to carry out this natural behaviour. Sows are usually confined from a few days before giving birth until their piglets are weaned at around four weeks old. Not allowing sows to behave naturally can make them frustrated and stressed.
Despite a petition (now closed) on the UK Gov website that aimed to outlaw their use, farrowing crates are still legal in the UK. Today approximately 60% of UK sows are kept in farrowing crates around the time of giving birth. None of these is on RSPCA Assured farms as farrowing crates are strictly prohibited under the RSPCA welfare standards for pigs.
The routine use of farrowing crates has been banned in Sweden, Norway and Switzerland with Austria moving to the use of crates for shorter periods only by 2033. Denmark is planning on having 10% free farrowing accommodation by 2020, though this would still leave 90% of sows in farrowing crates and their use is still widespread in many other countries around the world.
Pregnant sows are usually placed in farrowing crates about five days before they are due to give birth, and they are kept in them until the piglets are weaned at approximately 28 days of age.
Sows on the RSPCA Assured scheme remain loose-housed at farrowing, either indoors in individual pens with more space to move about and material such as straw to root around in and build nests with, or outdoors in paddocks or runs with access to a dry, bedded, comfortable shelter.
Sow stalls can also be known as gestation crates. These are just different names for the same thing.
A farrowing crate is used to confine the sow from up to a week before giving birth, generally until the piglets are weaned at around four weeks. Farrowing crates are restrictive pens that prevent the sow from turning around, and which aim to reduce the risk of the sow lying on and crushing her newborn piglets. Farrowing crates are legal and common practice in the UK and Europe.
Sow stalls are individual, narrow stalls in which the sows are housed throughout their pregnancy (about four months) until they are about to give birth. Sow stalls, which prevent the sows from turning around and allow very little movement forwards or backwards have been banned in the UK since 1999 but are still used in many countries around the world.
The RSPCA welfare standards for pigs, which must be met throughout a pig’s life if any pork products, including sausages, bacon and ham, from that pig are to be labelled RSPCA Assured, don’t allow pigs to be kept in farrowing crates. Sows must be given room to turn around freely at all times and bedding such as straw for comfort and to allow them to build nests.
