Successful Pig Farming Guide

Domestic pig Wikipedia. The domestic pig Sus scrofa domesticus or only 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. The domestic pigs head plus body length ranges from 0. 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 animals bones, hide, and bristles are also used in commercial products. Domestic pigs, especially mini pig breeds, are kept as pets. Descriptionedit. Skeleton specimen of a swine. 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. A tilapia farming howto guide. Understanding the five needs of tilapia. Swine Feed and Nutrition. Swine feed is one of the most important factors in the successful raising of pigs, whether it is one pig or 2000 pigs. Goat farming means rearing goats for the purpose of harvesting milk, meat and fiber. Commercial goat farming business is contributing greatly to the economy and. The dental formula of adult pigs is 3. 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. Four hoofed toes are on each foot, or trotter, with the two larger central toes bearing most of the weight, but the outer two also being used in soft ground. Most domestic pigs have rather a sparse hair covering on their skin, although woolly coated breeds, such as the Mangalitsa, are raised. Pigs possess both apocrine and eccrine sweat glands, although the latter appear limited to the snout and dorsonasal areas. Pigs, however, like other hairless mammals e. Pigs are also less able than many other mammals to dissipate heat from wet mucous membranes in the mouth through panting. Introduction Special Relativity Resnick Solution Manual.

The domestic pig Sus scrofa domesticus or only Sus domesticus, often called swine, hog, or pig when there is no need to distinguish it from other pigs, is a large. Their thermoneutral zone is 1. C. 7 At higher temperatures, pigs lose heat by wallowing in mud or water via evaporative cooling although it has been suggested that wallowing may serve other functions, such as protection from sunburn, ecto parasite control, and scent marking. Pigs are one of four known mammalian species which possess mutations in the nicotinic acetylcholine receptor that protect against snake venom. Mongooses, honey badgers, hedgehogs, and pigs all have modifications to the receptor pocket which prevents the snake venom neurotoxin from binding. These represent four separate, independent mutations. TaxonomyeditThe domestic pig is most often considered to be a subspecies of the wild boar, which was given the name Sus scrofa by Carl Linnaeus in 1. Sus scrofa domesticus. Twain Scanning Software Pdf'>Twain Scanning Software Pdf. However, in 1. 77. Johann Christian Polycarp Erxleben classified the domestic pig as a separate species from the wild boar. He gave it the name Sus domesticus, which is still used by some taxonomists. HistoryeditArchaeological evidence suggests that pigs were domesticated from wild boar as early as 1. D1%81%D0%B2%D0%B8%D0%BD%D1%8C%D1%8F1.jpg' alt='Successful Pig Farming Guide' title='Successful Pig Farming Guide' />BC in the Near East in the Tigris Basin,1. Cafer Hyk, Neval ori1. New Guineans. 1. 6 Remains of pigs have been dated to earlier than 1. BC in Cyprus. Those animals must have been introduced from the mainland, which suggests domestication in the adjacent mainland by then. There was also a separate domestication in China which took place about 8. DNA evidence from subfossil remains of teeth and jawbones of Neolithic pigs shows that the first domestic pigs in Europe had been brought from the Near East. This stimulated the domestication of local European wild boar, resulting in a third domestication event with the Near Eastern genes dying out in European pig stock. Modern domesticated pigs have involved complex exchanges, with European domesticated lines being exported, in turn, to the ancient Near East. Historical records indicate that Asian pigs were introduced into Europe during the 1. In August 2. 01. 5, a study looked at over 1. Pumpkin King Game Boy more. The study found that the assumption of reproductive isolation with population bottlenecks was not supported. The study indicated that pigs were domesticated separately in Western Asia and China, with Western Asian pigs introduced into Europe, where they crossed with wild boar. A model that fitted the data included a mixture with a now extinct ghost population of wild pigs during the Pleistocene. The study also found that despite back crossing with wild pigs, the genomes of domestic pigs have strong signatures of selection at DNA loci that affect behavior and morphology. The study concluded that human selection for domestic traits likely counteracted the homogenizing effect of gene flow from wild boars and created domestication islands in the genome. The same process may also apply to other domesticated animals. The adaptable nature and omnivorous diet of the wild boar allowed early humans to domesticate it readily. Pigs were mostly used for food, but early civilizations also used the pigs hides for shields, bones for tools and weapons, and bristles for brushes. In India, pigs have been domesticated for a long time, mostly in Goa and some rural areas, for pig toilets. Though ecologically logical as well as economical, pig toilets are waning in popularity as use of septic tanks and sewage systems is increasing in rural areas. Among the animals that the Spanish introduced to Chilo Archipelago in the 1. Among other things pigs benefited from abundant shellfish and algae exposed by the large tides of the archipelago. Pigs were brought to southeastern North America from Europe by de Soto and other early Spanishexplorers. Escaped pigs became feral and caused a great deal of disruption to Native Americans, who had no domesticated animals, with the exception of dogs. Feral pig populations in the southeastern United States have since migrated north and are a growing concern in the Midwest. Considered an invasive species, many state agencies have programs to trap or hunt feral pigs as means of removal. Domestic pigs have become feral in many other parts of the world e. New Zealand and northern Queensland and have caused substantial environmental damage. Feral hybrids of the European wild boar with the domestic pig are also very disruptive to both environment and agriculture among the 1. South America from Uruguay to Brazils Mato Grosso do Sul Center West Region, and So Paulo state Southeast Region, where they are known as javaporcos from javali and porco, thus boar pigs. With around 1 billion individuals alive at any time, the domesticated pig is one of the most numerous large mammals on the planet. ReproductioneditFemale pigs reach sexual maturity at 31. The gestation period averages 1. Estrus lasts two to three days and the females displayed receptiveness to mate is known as standing heat. Standing heat is a reflexive response that is stimulated when the female is in contact with the saliva of a sexually mature boar. Androstenol is one of the pheromones produced in the submaxillary salivary glands of boars that will trigger the females response. The female cervix contains a series of five interdigitating pads, or folds, that will hold the boars corkscrew shaped penis during copulation. Females have bicornuate uteruses and two conceptuses must be present in both uterine horns for pregnancy to be established. Maternal recognition of pregnancy in pigs occurs on days 1. Behaviouredit.
