The facts of pig farming

The facts of pig farming


As I hear a lot of talk about pig farms lately these are the facts of pig farming as I see them. Although I no longer keep pigs having worked on my own and many other large pig units over a number of years I think I am in a good position to tell it as it in reality which is not like some media channels or Facebook posts portray it. Of all the areas of farming the misconception of what goes on in pig farms around the world is probably greater than any other. I hope to give some honest and open answers as to what goes on and what it’s like in the pig industry.

First off what prompted me to write this is partly due to documentaries like Channel 4s How to steal pigs and vegan activists illegally breaking into pig farms. I would ask people to keep an open mind on why this is happening and who is funding all the billboards and adverts that you see around the country.

Channel 4 have done a few programs which appear to be anti meat but is also worth noting that they have a seven figure stake in a so called meatless farm company so there could be a conflict of interest there. It is clear to me that when activists break into a farm the first place they go to for photographs is the area where dead pigs are waiting to be collected by the knackery trucks. Animals die on every farm but to put it in context some of the pig farms could have several thousand animals so it would be like going to a morgue in a town with several thousand people and pulling out dead bodies to photograph saying what a horrible town it is.

The next place they will go is the hospital yes large piggeries have pig hospitals where they can be isolated or put with other sick or injured pigs to help their recovery. The reason for this is pigs like lots of other animals have a pecking order and if one gets sick or weak healthy pigs will bully that animal. Some will get lame or injured and need time in a pig hospital but again in context a very small amount. The rate of mortality is a good way to judge how things are going and in the weaners or fattening section this is usually around 1%

The other place you will see lots of footage of is the farrowing house which is where sows give birth and the sows are in farrowing crates. You may be given the impression that the poor pigs are locked up in cages for their entire lives but in reality they are only in the farrowing room for 4 weeks and the reason for the sow crate is for the piglets welfare and protection.


The mortality in the farrowing room with newborn piglets (like any newborn animals) is the highest of the entire piggery and could be anywhere from 5 to 14% most of which is due to being crushed by their mother in the first few days of life. The purpose of the sow crate is to prevent the sow lying down too quickly so the newborn piglets have a better chance to move out of the way
New freedom farrowing crates are now available for new builds that can be opened up after a few days so that the sow can turn around and move about more once the piglets are old enough to move quickly out of the way when their mother is about to lie down. I don’t know why it is so hard to get a sow to stand up once she lies down for a nap but she usually will not want to stand up again even if her piglets are being crushed to death underneath her, which is the only reason that they are in crates.

Teeth grinding

Newborns also have their teeth clipped or the points grinded smooth to prevent them from damaging their mothers teats or each other with their sharp needle like teeth. After a few days they have the tips of their tails clipped this is to prevent tail biting later on. At a few days old the piglets tail is about as thick as an earthworm and the don’t take too much notice for instance a piglet could be suckling it’s mother and when it’s tail is cut it will go straight back to sucking the sow once it is put down on the floor almost oblivious to what has just happened.

It is done with a gas clipper which cuts and seals the wound at the tail end and is similar to a gas calf dehorner but in my opinion the piglets do not take any notice of it. Tail biting can be a problem on any indoor pig unit from time to time and there has been lots of study into causes and prevention like adding enrichment and toys for the pigs which I won’t go into now as that subject could have a post all of it’s own. In short tail docking of piglets is necessary and done under veterinary advise on most indoor pig farms as best practice to prevent tail biting amongst older pigs.

When sows leave the farrowing house after 4 weeks they go into the service area into a cage called a basket and after 4 days she comes in heat and is served by artificial insemination 2 days after that when she is no longer in heat she is put in a loose house with her peers for the next 16 weeks. The reason they are put into the baskets or cage for service is because when a large number of sows come into heat at the same time there is a high risk of injury due to sows mounting each other. Other than that all pigs spend their lives in loose housing with their own peers.

Most stock persons looking after the pigs do a very good job an always adhere to the five freedoms the last thing they need is to be harassed by a gang of misguided activists who have neither trained in agriculture or animal husbandry and who’s only aim is to photograph dead or sick animals in order to spread their propaganda.

Some questions and answers


Are pigs kept in cages all their lives? No only breeding sows at birthing and service and for welfare reasons


Are indoor pigs full of antibiotics ? No most pigs will never get an antibiotic.



What about sick pigs ? If a pig gets sick and needs an injection records are kept and withdrawal periods adhered to and are also tested at factory for traces of antibiotics.



Do pigs get sick much? No more than a cat, dog, cow, sheep or any other animal.



What else are pigs given? They can be given vaccination shots and a wormer.



Are pigs in overcrowded pens? No the are give adequate space recommended by the department of agriculture


Why are pigs reared indoors ? Because it’s the most efficient way to rear them and control ventilation and                 temperature for optimal growing conditions



Can they be reared outdoors ? Yes except for winter but it costs more and everyone wants cheap food.



Are indoor pigs happy? Yes they are some of the happiest and healthiest animals that I have seen.



Do pigs smell? Yes they don’t sweat and smell bad but you get used to it and they don’t mind.



Am I making this up? No I don’t keep pigs anymore but respect the hard work and dedication of the farmers that do.

As you might have seen some of the older pig units made to look bad here is the best of what a modern pig unit looks like

  1. This is a great article to read to know more about the true about pig farming.

    I know how hard farmers work and how many different problems they need to face and solve out every single day! I must say farmers know what they love to do as a business, and they do it the best they can.

    I’ve visited a few farms in my life, and I can say, some farms really treat animals well, it’s good to know more about good farms when people love to work and where people are happy taking care of animals as they grow up. 

  2. You pig farming is very different from the one that I grew up with when I was in Thailand, I remembered that they eat anything like eating food scraps from school cafeterias and also hanging out in their pens in a mud and sleep all day. Yet again Thailand is a 3rd world country and we are talking about the the late 80s and 90s, I am sure things have changed. I have nothing against vegan or meatless movement but we all have our own mind to make a decisions. I get it that the documentary is here to bring the awareness but it is not ok to mislead people. To be honest, I think most of the vegan product are too processed and bad for our health. I only support them for animal cruelty movement but not to the extreme. 

    Thank you for spending time educating us about the process of pig farming. I have no idea that they do not need antibiotic but why is that though? They are stronger than cows? 

    1. Thank you I would agree with you everyone should have the right to chose what they want to eat but without attacking others who might not have the same beliefs. No one should support animal cruelty but people should not be falsely accused of it either. Like taring everyone with the one brush .  

  3. Your job is to dismantle the criminals who enter pig farms just to film or photograph the “misfortunes” of these farms. As you can say, they have not been trained about livestock or animal behavior . But they should not need to spread manipulative propaganda. I liked the video you posted as well, so I had the opportunity to see a modern pig computer-assisted hernia.
