US bid to grow human organs for transplant inside pigs
Scientists in the United States are trying to grow human organs inside pigs. They have injected human stem cells into pig embryos to produce human-pig embryos known as chimeras. The team from University of California, Davis says they should look and behave like normal pigs except that one organ will be composed of human cells. Human induced pluripotent stem cells are injected into the embryo. The team at UC Davis hopes the human stem cells will take advantage of the genetic niche in the pig embryo and the resulting foetus will grow a human pancreas.
The main concern is that the human cells might migrate to the developing pig’s brain and make it, in some way, more human. His team has previously injected human stem cells into pig embryos but without first creating the genetic niche. By deleting a key gene involved in the creation of the pig pancreas, they hope the human cells will have more success creating a human-like pancreas. His team is also trying to create dopamine-producing human neurons from chimeric embryos to treat patients with Parkinson’s disease. Gene editing has revitalised research into xenotransplantation, and the concept of using animal organs for humans.
In the mid-90s there were hopes that genetically modified pigs might provide an endless supply of organs for patients, and that cross-species transplants were not far off. The scientific teams believe human-pig chimeras should look and behave like normal pigs except that one organ will be composed of human cells.
Natural Pig Farming
The ‘standard’ natural pig farming system meets many of the needs of the pig. One core need is for the pig to keep cool through allowing it to regulate its body temperature as it is unable to release heat through sweating. The natural pig farming system has an open sided sty design that allows the breeze and wind to provide cool air. My natural pig farming system goes step further in ensuring that the pigs can keep cool. The natural coolness of the soil provides the cool that a pig seeks.
A pig doesn’t want to lie in wet mud all day and night, so our natural pig farming practice is to add water during at certain times of the day when the weather is hottest, and then let it dry naturally. We apply the water with a watering can which enables the pigs to get a cool shower as we pour. Apart from keeping the pigs cool, the great benefit of providing mud in the pen is that the pigs clearly appreciate it. The mud bath also allows the pigs to carry out rooting behavior, a activity which they evidently enjoy more than rooting in the sty deep bed flooring. When we top up with new soil the pig get immense satisfaction rooting amongst it, rolling around in it, and eating the more tasty parts of it.
Incorporating a mud bath is an addition to the basic deep bed natural pig farming model. This is not a sign of them living in squalor or neglect; rather, it’s a badge that shows that the pigs are living a happy natural life doing what a pig enjoys doing; namely wallowing to its hearts content.
Silkie Guinea Pig: Care, Characteristics, Diet, Health & Origins
The Silkie guinea pig is very unique as a breed and is most well-known for its’ wild hairstyle. Often compared to an actors’ or actresses’ wild, long, and flowing hair locks, the Silkie guinea pig is quite popular as a domestic pet but also in show rooms around the world. In addition to having vivacious, lively personality traits, the Silkie guinea pig often performs well against other breeds in show room competitions. Unlike most breeds of guinea pigs, the Silkie has very unique hair. Similar to the mane of a lion, the hair of the Silkie guinea pig is long and soft, which also flows down past its’ neck and shoulders.
A Silkie guinea pig with a satin coat will have shinier and softer hair than those regular Silkie guinea pigs. The Silkie is also very laid-back, easy-going, and is not hyper like other guinea pig breeds. In Europe, most people call them Sheltie guinea pigs instead of Silkie guinea pigs. The Silkie guinea pig was originally discovered in the 1970s around the same period of time as the Skinny guinea pig. The Silkie is also considered to be an exotic breed of guinea pigs due to the fact that it is part of a crossbreeding success between two other types of guinea pigs.
Keeping the silky, smooth, and long hair of the Silkie guinea pig clean and vibrant requires near-constant upkeep. Most of all, it’s imperative to gently brush the hair of the Silkie guinea pig once per day, at least, in order to keep it’s long locks from becoming entangled with each other.
texel guinea pig
A Texel guinea pig is a relatively new cavy breed – and a very cute one at that! The Texel guinea pig is a new cavy breed! It was first developed in 1980 in the U.K. when a British Rex guinea pig was crossed with a Silkie guinea pig. So in a Texel matte coat guinea pig, the basic genotype would look like this: llrrststT-Sn-rxrx.
If the Texel guinea pig in question also possesses a Satin coat sheen, the genotype would instead look like this: llrrsrstT-snsnrxrx. The Texel guinea pig coat can be shown in any color, whether solid or mixed/patterned. If you are interested in showing your Texel guinea pig, there are no colors or patterns that are currently inadmissible for this guinea pig breed in the show ring. If you are caring for a very young Texel guinea pig, you can expect to see some coat growth as your Texel reaches maturity. It is the Texel’s long and tangle-prone coat that makes this guinea pig breed less suited to be a child’s first pet or a first guinea pig for any owner who is short on time.
Breeders recommend not using wood shavings as bedding for the Texel guinea pig. While your Texel guinea pig will have big, round, expressive eyes, sight is not a guinea pig’s best sense. The Texel guinea pig, like many guinea pig breeds today, can live anywhere from 5 to 7 years. By some accounts, the Texel is perhaps the third most popular of all guinea pig breeds! In any case, the baby Texel guinea pig is one of the cutest you will ever see!
