The Tamworth, also known as Sandy Back and Tam, is a breed of domestic pig originating in its namesake Tamworth, Staffordshire United Kingdom, with input from Irish pigs.[1] It is among the oldest of pig breeds, but as with many older breeds of livestock, it is not well suited to modern production methods and is listed as "Threatened" in the United States[2] and "Vulnerable" in the UK by the Rare Breeds Survival Trust, as fewer than 300 registered breeding females remain.[3] This animal is of ginger to red colouration and is thought to have descended from wild boars, via native pig stock of Europe. Principal populations today are in the United Kingdom, Australia, the United States, New Zealand, and Canada.

Description

This breed exhibits an elongated head shape and a long, narrow body.[4] The ears are erect and pointed, while the face has rectilinear lines as well as the snout. Colours range from a pale gingery to dark mahogany red. Early in the breed history, colours were orange and purple, but breeding has been conducted to remove the orange colouration. The bristle density protects their skin from ultraviolet harm from the sun; nevertheless, when they moult between June and August (in the Northern Hemisphere), shade is sought along with copious mud coating to prevent sunburn. The mud coating also provides a way for the pigs to cool down, as pigs cannot sweat.

Tamworths are considered a medium-sized porcine breed, with a full-grown boar ranging from {{Convert|250|to|370|kg|lb|abbr=on|sigfig=2}} and the mature sow from {{Convert|200|to|300|kg|lb|abbr=on|sigfig=2}}. The adult length ranges from {{Convert|100|to|140|cm|in|abbr=on|sigfig=2}} and heights of about {{Convert|50|to|65|cm|in|abbr=on|sigfig=2}} are common.[5] The curled adult tail is about {{Convert|24|to|30|cm|in|abbr=on|sigfig=2}}. This animal is characterised by having a neck and legs that are long, and by deep sides, but narrow backs. Its ham structures are quite muscular and firm. The breed is also known for having excellent foot structure and a good skeletal system. Litter sizes are typically somewhat smaller than commercial breeds. Unacceptable features according to breed aficionados are: curly hair, coarse mane, turned up nose, and dark spots on the coat.

Behaviour

The most salient feature of the Tamworth is its great hardiness with respect to adverse climates. Thus, the breed does well in its more northerly settings such as Scotland and Canada, where winters are severe, not only in regard to cold but also high winds. The animal is not only durable and rugged, but also is extremely well-suited for forest grazing, being able to thrive on bracken. Tamworths graze compatibly with cattle, being able to retrieve forage that cattle leave behind in the open pasture. This said, Tamworth pigs can be protective of their territories, thus somewhat aggressive towards any other livestock in the same pasture. This animal is very efficient at excavation while rooting for food in the forest or pasture. The breed is used in forage-based farming systems. The sows demonstrate good maternal skills, being consistent in suckling all littermates. Litters normally range in size from six to ten piglets. Piglets at birth are usually wild and wary of humans, but easily adjust to human interaction. Tamworths display a good disposition and enjoy the attention of humans.

History

The Tamworth breed pig originated in Sir Robert Peel's Drayton Manor Estate at Tamworth, Staffordshire, after the existing herd was interbred from 1812 with pigs from Ireland known as "Irish Grazers", that Peel had seen in Ireland in 1809.[6] Much of the improvement of the breed took place in Staffordshire and also in the counties of Warwickshire, Leicestershire, and Northamptonshire, England. The breed appears among the least interbred with non-European breeds, and therefore one of the closest to the original European forest swine.

In 1865, Tamworths achieved English breed recognition and in 1885 the herd book was started. Tamworths were imported into the United States by Thomas Bennett of Rossville, Illinois, in 1882. Soon they entered Canada, where a population now exists. Breed associations for Tamworth swine are active in the UK, the USA, and Canada; however, they are considered a minor breed. From 1913 to mid-century, the breed reached peak numbers in Canada, reaching up to 10% of the total swine population. In Australia, the breed reached peak numbers of about 1000 in the mid-20th century.[7] Modern herd numbers have reached critically small numbers in each of the five recognised countries holding these animals.

Genetics and conservation

Being a breed considered quite distant genetically from most modern commercial swine, the Tamworth is considered an excellent choice for cross-breeding. It is sometimes called a "bacon pig" because of its ability to achieve high body mass without having much actual fat. Known current populations (breeding females) are: USA (1000); United Kingdom (340); Canada (254); Australia (55), and New Zealand (40)[8]. The breeding societies in each country consider conservation the highest priority, with a great emphasis upon record-keeping.
