Swine vesicular disease

Swine vesicular disease (SVD) is an acute, contagious viral disease of swine caused by the swine vesicular disease virus, an enterovirus. It is characterized by fever and vesicles with subsequent ulcers in the mouth and on the snout, feet, and teats. The pathogen is relatively resistant to heat, and can persist for a long time in salted, dried, and smoked meat products.

Transmission

The disease can be introduced into a herd by feeding garbage containing infected meat scraps, by bringing in infected animals, or by direct contact with infected feces (such as in an improperly cleaned truck).

Clinical signs

Prevention and control

There is no vaccine for SVD. Prevention measures are similar to those for foot-and-mouth disease: controlling animals imported from infected areas, and sanitary disposal of garbage from international aircraft and ships, and thorough cooking of garbage. Infected animals should be placed in strict quarantine. Eradication measures for the disease include quarantining infected areas, depopulation and disposal of infected and contact pigs, and cleaning and disinfecting contaminated premises.

Domestic pig

The domestic pig (Sus scrofa domesticus or Sus domesticus), often called swine, hog, or pig when there is no need to distinguish it from other pigs, is a large, even-toed ungulate. It is variously considered a subspecies of the wild boar or a distinct species. Its head-plus-body-length ranges from 0.9 to 1.8 m (35 to 71 in), and the adult can weigh between 50 to 350 kg (110 to 770 lb). Compared to other artiodactyls, its head is relatively long, pointed, and free of warts. Even-toed ungulates are generally herbivorous, but the domestic pig is an omnivore, like its wild relative.

Domestic pigs are farmed primarily for the consumption of their meat, called pork. The animal's bones, hide, and bristles are also used in commercial products. Domestic pigs, especially the pot-bellied pig, are sometimes kept as pets.

Description

The domestic pig typically has a large head, with a long snout which is strengthened by a special prenasal bone and a disk of cartilage at the tip. The snout is used to dig into the soil to find food, and is a very acute sense organ. The dental formula of adult pigs is 3.1.4.33.1.4.3, giving a total of 44 teeth. The rear teeth are adapted for crushing. In the male the canine teeth can form tusks, which grow continuously and are sharpened by constantly being ground against each other.

Composition

Musically, "Swine" is a dubstep and industrial song. Based on the "teaser" of Gaga rehearsing for the iTunes Festival, Entertainment Weekly described "Swine" as a "real shocker with Nine Inch Nails lyrics and bull-in-a-bong-shop Deep Purple groove".Consequence of Sound noted the creation of the Twitter hashtag #swinefest and called the song a "melancholy piano ballad that eventually erupts into a raging pop-rocker, backed by piercing guitar and synths". Gil Kaufman of MTV News described the track as a "Rock-Heavy" song. Lyrically, the song denounces a suitor by comparing them to a pig.
