Facts about Neijiang Pigs. Neijiang is a domestic pig breed that is native to China. The Neijiang Pig breed was developed in the Sichuan Basin, which is situated in the southwest part China. The Neijiang Pigs are largely found in this area because the type of weather is mild, and agriculture is well urbanized, and the area is rich in pig feed supplies.
The "Neijiang Pig" breeds are relatively big in size, and they have a physically powerful body structure. The thickness of the skin of the Neijiang Pigs is about 9/32 inches (7 mm), and they have a thick back fat between 1 23/64 inches and 2 9/32 inches (3.4 cm and 5.7 cm). The Neijiang Pig breeds are precocious, as well. The juvenile boar may escalate the female even when it attains the age of 2 months after its birth. The mature spermatozoa can be seen in the epididymis at 71 days to 78 days. The domestic female pigs can be mated and turn out to be pregnant within 90 days subsequent to the birth. The average litter size of the Neijiang Pig breed is 10.6 piglets, and they have seven pairs of teats.
The most distinct feature of the Neijiang Pig breed is the hard hoof that looks like that of a mule. The Neijiang Pigs with concrete hooves have drawn the attention of countless authors, as well as Darwin and Aristotle over the centuries. Yet of all the mule-footed pigs described, the Neijiang Pig breed is the only recognized population with a strain standard and an extended history of agricultural application. The Neijiang Pig breed is unique to China and it is critically uncommon. However, latest events have shown the way to more optimism about its survival.
Research on the xenoantigens of pancreatic tissues of the Neijiang pig
The look and sharing of xenoantigens in pancreatic tissue of the Neijiang pig breed were examined with immune-histo-chemistry method. Bandeiraea simplicifolia isolectin B4, standard human serum and anti-human A, B, and H monoclonal antibodies were exercised as the main antibody to investigate the appearance of xenoantigens in the pancreatic tissues from ten Neijiang pigs. The outcomes revealed that when compared with the pessimistic outcomes of human blood H and B type antigens, the alpha-Gal antigen was extremely expressed in the duct epithelium and pancreatic vascular endothelial cells. The human being blood A-category antigen was exceedingly expressed on a few islet cells, a few exocrine secretor cells and each and every one of the duct epithelium. As there are pre-departed xenoantibodies against the Neijiang pig pancreas cells in human being serum, cross-matching examination and graft pre-treatment are required earlier than the medical transfer of pancreas. The appearance of xenoantigens in the Neijiang pig breeds is different from other pig breeds, which suggests that in search of a pig strain that includes less xenoantigens is feasible.
Appearance and sharing of human blood category antigens in the tissues of the Neijiang pig
The appearance and sharing of being blood type A, O and B antigens in Neijiang pigs were investigated. The anti-human type of blood, such as A, H and B monoclonal antibodies were employed as the main antibody, and the immune-histo-chemistry EnVision method was employed to identify the appearance of A, H and B antigens in the tissues from 10 Neijiang pigs.
From the investigation, it was found that the H and B antigens were not available in the tissues of all the 10 investigated Neijiang pigs. While the antigen-A was discovered in all above tissues of this pig breed, except in the pigs’ vascular endothelial cells.
So, it was concluded that the antigen-A did not subsist on the pigs’ vascular endothelial cells, so it did not function as a hyperactive antigen in the Neijiang pig breeds to human being xenotransplantation.
The saliva of Neijiang Pigs contains pheromones-( A chemical substance used to attract a mate) similar to that of other pig breeds that communicate their sexual wants. The male Neijiang Pigs discharge this steroid and female pigs will go to vast lengths to acquire a smell of the sent.
Neijiang Pigs are raised for there meat such as ham, sausage, bacon and pork chops. Pigs can make great pets. "A wild male pig is called a boar"- meaning uncastrated male pig, that lives in the wild and can be hunted. "Feral pig or hog is defined as a wild boar" can be a very big danger where humans habitat.
Neijiang Pigs have small lungs compared to their body size.
The term Swine: is any variety of omnivorous, even-toed ungulates of the family Suidae, this includes hogs, boars and pigs having a short neck, thick skin a movable snout and a stout body.
Neijiang Pigs unlike is said, happen to be very clean animals. Neijiang Pigs make sure their bathroom area is far away from where they eat, lie down and rest, even piglets (baby pigs) will find a place to go to the bathroom, far away from their nest. A Neijiang Pig averages 6 to 10 baby piglets in a litter and will have two to three litters per year. The sows nurse their piglets for about three to five weeks. When Neijiang Pig Piglets are weaned off of their mother’s milk, they are not called piglets but are known as shoats. Piglets at birth weigh about 2.5 pounds (1.1 kilograms), and on average, will double their weight in one week.
Neijiang Pigs have 44 teeth when full grown, when they are baby pigs (piglets) the have 28 teeth which will fall out when they are 12 months old. Just like human teeth, the Neijiang Pig has an enamel coating that makes the pigs teeth stronger and helps it curb disease. Neijiang Pigs chew their food because pigs have a digestive system similar to a human digestive system and cannot digest food that is not chewed.
A pig is the last of the 12 animals in the Chinese zodiac. The pig represents, happiness, honesty, fortune and virility in China. A female adult Neijiang Pig is called a (sow) and the male adult wild pig is called a (boar). The lifespan of a Neijiang Pig is between 9 and 15 years
Neijiang Pigs do not sweat a lot, that's why they cover themselves in the mud to keep their bodies cool. The expression "sweating like a pig" comes from a reference to pig iron, which comes form iron smelting.
Neijiang Pigs are very intelligent, not like people think, that pigs are dumb animals. A Neijiang Pig can drink between 10 to 14 gallons (37.8 to 53 liters)of water in a day. Neijiang Pigs are omnivores like humans, an omnivores, (definition-they eat both other animals and plants). The Neijiang Pig snout is its most important tool for finding food. The Neijiang Pigs snout is used for their excellent sense of smell and they have poor eyesight.
"Scientific name for Pig Sus scrofa", the wild swine (Boar) from the old world with a narrow body and prominent tusks is from where most domestic swine come from. The "fear of pigs Swinophobia".
