Pig slaughter

Pig slaughter is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pig slaughter rather than just read about it. In short: Pig slaughter is the work of slaughtering domestic pigs to obtain pig meat (pork). It regularly happens as part of traditional and intensive pig farming, which is both a common economic activity as well as a traditional feast in some European and Asian countries.

Key takeaways

  • Pig slaughter belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Pig slaughter to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Pig slaughter from memory before moving on to harder problems.

Reference excerpt

Pig slaughter is the work of slaughtering domestic pigs to obtain pig meat (pork). It regularly happens as part of traditional and intensive pig farming, which is both a common economic activity as well as a traditional feast in some European and Asian countries.

Agriculture Pigs are slaughtered at different ages. Generally they can be divided into piglets, which are 1.5 to 3 months old; the fattening pigs, intended for pork and bacon, which are 4 months to one year old; and finally the older pigs, such as sows (female pigs) and boars (uncastrated male pigs). The meat obtained from piglets is subdivided into more meaty or more fatty, determined by the thickness of bacon. Male hogs are usually castrated a month before slaughter. Their meat quality is determined on the mass of halves and the thickness of bacon on the back. The Humane Slaughter Association states that the transport of pigs to slaughter and all the other procedures and circumstances leading up to the actual act of stunning and killing the pig are, in modern times, often carefully arranged in order to avoid excessive suffering of animals, which both has a humane rationale as well as helping provide for a higher quality of meat. Animal rights groups have recorded images of pigs being transported to slaughter in cramped and unhygienic conditions. They state that the transportation does cause suffering, which has economic rationale. Research also confirms stunning of pigs in CO2 gas chambers in particular has animal welfare concerns, as the high concentrations of CO2 used are highly aversive to pigs. Typically, pigs are first rendered unconscious using one of the following means: stunning using electric current applied with electrodes, or stunning using captive bolt pistol, and inhalation of high concentration CO2, the last being the most common. In some cases a .22 pistol/rifle which is shot directly into the brain is used instead. The pigs are then exsanguinated, usually via the carotid artery and the jugular vein, often by hoisting them on a rail. After the blood is gone, the carcass is drenched in hot water in a device called a pig scalder which helps in the removal of hair, which is subsequently completed by using scissor-like devices and then if necessary with a torch. However, in many countries across the world, rendering the pig unconscious is not standard practice and exsanguination occurs whilst the pigs are fully conscious. The pig is then eviscerated, the head is usually removed, and the body is cut into two halves. The remaining halves are washed to remove any remaining blood, bacteria or remnants of bone, and then cooled down in order to help with the process of cutting and deboning. In the European Union, the Regulation (EC) of the European Parliament and of the Council No. 852/2004, 853/2004 and 854/2004 cover various aspects of hygiene of foodstuffs that includes pig slaughter.

European tradition

Pig slaughter is a tradition known in numerous EuropeEuropean countries and regions: Armenia (Խոզ մորթելը, Khoz mort’ely), in Albania, it is only traditional among Christians, Austria (Sautanz), Bulgaria (колене на прасе, kolene na prase), North Macedonia (колење на прасе, kolenje na prase), Croatia (kolinje), the Czech Republic (zabijačka), France (tue-cochon), Georgia (ღორის დაკვლა, ghoris dak’vla), Greece, Hungary (disznóvágás, disznótor or disznóölés), Italy (maialatura), Moldova, Montenegro (svinjokolj), Poland (świniobicie), Portugal (matança), Romania (tăiatul porcului, Ignat), Russia (Убой свиней, Uboy sviney) Serbia (svinjokolj), Slovakia (zabíjačka), Slovenia (koline), Spain (matanza), Ukraine, Corsica and others. Family hog pens have also existed in the United States on small family farms, but have become rare in recent decades.

Traditional autumn activity

The slaughter traditionally takes place in the autumn and early winter, and the timing has several practical considerations. It can start as soon as it gets cold, as the cold is required as a natural method of preserving the relatively large quantities of meat during the butchering. Yet, because people often do the work in the open, it is preferable that the temperatures aren't too much below freezing during this time, hence the slaughter rarely extends into winter. Also, slaughter activities typically need to produce results before the Christmas season, to provide for the festive cuisine. In the past, this was also the only time of the year when people could afford to eat larger amounts of meat. In modern times, almost any family in Europe that is so inclined can afford to slaughter, yet there is also an abundance of pre-processed meat in the shops, so the traditional method of slaughtering is becoming more and more of a folk custom rather than a necessity. The slaughter requires numerous preparations, including troughs, large quantities of boiling water, large wooden barrels for storing meat, pots, sharp knives, and in modern times also artificial intestines (hoses for various sausages). Historically, butchering was a trade passed from father to son. Today the initial slaughter is normally performed by a professional butcher. After that, the meat is butchered by laymen, and the process is accompanied by various local rituals.

Worked examples

Example 1 — a first encounter with Pig slaughter

Start with the simplest possible case. Write down what Pig slaughter claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pig slaughter before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pig slaughter ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pig slaughter

In research
Pig slaughter appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Pig slaughter in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Pig slaughter is common in secondary-school and first-year university syllabi. It links to neighbouring topics Animal killing, Belarusian cuisine, Bulgarian cuisine, so understanding it makes those chapters shorter.
In everyday life
Look for Pig slaughter outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
