A truffle hog is any domestic pig used for locating and extracting the fruit bodies of the fungi known as truffles from temperate forests in Europe and North America. Pigs have an exceptional sense of smell, and are able to identify truffles as deep as three feet underground. It was thought that the natural sex hormone androstenol of the male pig, which is also found in truffles, was responsible for this ability; [1] however this has been proven false, as the molecule dimethyl sulphide was shown to signal instead. [2] Pigs also have a natural affinity for rooting in the earth for food. They are trained to hunt truffles by walking on a leash through suitable groves with a keeper. [3]

History

The use of pigs to hunt truffles is said to date back to the Roman Empire, but the first well-documented use comes from the Italian Renaissance writer and gastronomist, Bartolomeo Platina, in the 15th century. [3] Later references to truffle pigs include John Ray in the 17th century. [3]

In 1875, a truffle hog could cost up to 200 francs. [4] A skilled truffler could more than make up for this investment from the high price of truffles on the gourmet food market.

In Italy, the use of pigs in truffle hunting has been prohibited since 1985, as the animals can cause damage to the mycelia of truffles while digging, reducing the production rate for a number of years. [5]

Mycology is the branch of biology concerned with the study of fungi, including their taxonomy, genetics, biochemical properties, and use by humans. Fungi can be a source of tinder, food, traditional medicine, as well as entheogens, poison, and infection. Yeasts are among the most heavily utilized members of the Kingdom Fungi, particularly in food manufacturing.

<i>Sus</i> (genus) Genus of even-toed ungulates

Sus is the genus of domestic and wild pigs, within the even-toed ungulate family Suidae. Sus include domestic pigs and their ancestor, the common Eurasian wild boar, along with other species. Sus species, like all suids, are native to the Eurasian and African continents, ranging from Europe to the Pacific islands.

<span class="mw-page-title-main">Hunting</span> Searching, pursuing, and killing wild animals

Hunting is the human practice of seeking, pursuing, capturing, and killing wildlife or feral animals. The most common reasons for humans to hunt are to obtain the animal's body for meat and useful animal products, for recreation/taxidermy, although it may also be done for resourceful reasons such as removing predators dangerous to humans or domestic animals, to eliminate pests and nuisance animals that damage crops/livestock/poultry or spread diseases, for trade/tourism, or for ecological conservation against overpopulation and invasive species.

<span class="mw-page-title-main">Wild boar</span> Species of mammal

The wild boar, also known as the wild swine, common wild pig, Eurasian wild pig, or simply wild pig, is a suid native to much of Eurasia and North Africa, and has been introduced to the Americas and Oceania. The species is now one of the widest-ranging mammals in the world, as well as the most widespread suiform. It has been assessed as least concern on the IUCN Red List due to its wide range, high numbers, and adaptability to a diversity of habitats. It has become an invasive species in part of its introduced range. Wild boars probably originated in Southeast Asia during the Early Pleistocene and outcompeted other suid species as they spread throughout the Old World.

<span class="mw-page-title-main">Truffle</span> Fruiting body of a subterranean ascomycete fungus

A truffle is the fruiting body of a subterranean ascomycete fungus, one of the species of the genus Tuber. More than one hundred other genera of fungi are classified as truffles including Geopora, Peziza, Choiromyces, and Leucangium. These genera belong to the class Pezizomycetes and the Pezizales order. Several truffle-like basidiomycetes are excluded from Pezizales, including Rhizopogon and Glomus. Truffles are ectomycorrhizal fungi, so they are found in close association with tree roots. Spore dispersal is accomplished through fungivores, animals that eat fungi. These fungi have ecological roles in nutrient cycling and drought tolerance.

Hog-dog rodeo or hog-dogging, is a spectator event that simulates wild or feral boar hunting with dogs. It requires specially trained and bred "hog dogs" that are used to bay and sometimes catch a hog or boar. In most cases, bay dogs psychologically control the pig and no physical contact occurs. In some cases, however, such as Uncle Earl's Hog Dog Trials, along with bay dog events, catch dog events have been included in the past. In these, specially bred and equipped dogs caught and held the hog by the ears before the animals were quickly separated by a person who hog-tied the pig.

Sausage casing, also known as sausage skin or simply casing, is the material that encloses the filling of a sausage. Natural casings are made from animal intestines or skin; artificial casings, introduced in the early 20th century, are made of collagen and cellulose. The material is then shaped via a continuous extrusion process—producing a single sausage casing of indefinite length—which is then cut into desired lengths, usually while the extrusion process continues.

<span class="mw-page-title-main">Feral pig</span> Any type of feral domesticated pig, wild boar, or hybrid

A feral pig is a domestic pig which has gone feral, meaning it lives in the wild. The term feral pig has also been applied to wild boars, which can interbreed with domestic pigs. They are found mostly in the Americas and Australia. Razorback and wild hog are sometimes used in the United States refer to feral pigs or boar–pig hybrids.

<span class="mw-page-title-main">Dimethyl sulfide</span> Chemical compound

Dimethyl sulfide (DMS) or methylthiomethane is an organosulfur compound with the formula (CH3)2S. It is the simplest thioether and has a characteristic disagreeable odor. It is a flammable liquid that boils at 37 °C (99 °F). It is a component of the smell produced from cooking of certain vegetables and seafoods. It is also an indication of bacterial contamination in malt production and brewing. It is a breakdown product of dimethylsulfoniopropionate (DMSP), and is also produced by the bacterial metabolism of methanethiol.

The pig, also called swine or hog, is an omnivorous, domesticated, even-toed, hoofed mammal. It is named the domestic pig when distinguishing it from other members of the genus Sus. It is considered a subspecies of Sus scrofa by some authorities, but as a distinct species by others. Pigs were domesticated in the Neolithic, both in East Asia and in the Near East. When domesticated pigs arrived in Europe, they extensively interbred with wild boar but retained their domesticated features.

A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks instead of being slaughtered to harvest animal products. Some are used for their physical strength or for transportation, while others are service animals trained to execute certain specialized tasks. They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or leather.

<span class="mw-page-title-main">Boar–pig hybrid</span> Hybridised offspring

Boar–pig hybrid is a hybridized offspring of a cross between the Eurasian wild boar and any domestic pig. Feral hybrids exist throughout Eurasia, the Americas, Australia, and in other places where European settlers imported wild boars to use as game animals. In many areas, a variable mixture of these hybrids and feral pigs of all-domesticated original stock have become invasive species. Their status as pest animals has reached crisis proportions in Australia, parts of Brazil, and parts of the United States, and the animals are often freely hunted in hopes of eradicating them or at least reducing them to a controllable population.

<i>Tuber melanosporum</i> Black truffle

Tuber melanosporum, called the black truffle,Périgord truffle or French black truffle, is a species of truffle native to Southern Europe. It is one of the most expensive edible fungi in the world. In 2013, the truffle cost between 1,000 and 2,000 euros per kilogram.

Australia has a population of about 26 million while the Commonwealth Government estimating there are 640,000 recreational hunters in the country. There are around 6 million legally owned guns in Australia, ranging from airguns to single-shot, bolt-action, pump-action, lever-action or semi-automatic firearms.
