A clone horse is a genetically identical replica of another horse. Horses are typically cloned in order to preserve their valuable bloodlines, often in cases where a superior or highly valuable horse has died or been gelded and therefore is unable to produce offspring.
- Cloned horses display the same mental behaviors and capabilities as any other horse. They need adequate nourishment to fully develop their bodies and constant exercise to build their muscles. Most importantly, training them for competitive racing requires the same time and effort as horses produced through traditional methods.
Is cloning horses legal?
Though cloning is allowed within most horse breed registries, it’s banned for racing thoroughbreds and quarter horses. Even so, thoroughbreds and quarter horses are regularly cloned and participate in disciplines such as dressage, polo and rodeo.
How much is it to clone a horse?
#1 – It costs about $150,000 to clone a horse. A single sperm sample from a top horse can be sold for up to half a million dollars. For people breeding horses worth millions of dollars, $150k for the genes of a proven competitive horse is well worth the price.
Do cloned horses have the same personality?
Myth: Clones have exactly the same temperament and personality as the animals from which they were cloned. Although your horse’s clone may be easy-going, he would have to have exactly the same life experiences as your original horse in order to have the same temperament.
What race horses have been cloned?
Others include dressage, showjumping, three-day-eventing, polo and carriage horse racing. It is the first time an elite racehorse has been cloned, and comes two years after the appearance of Prometea, the first and only other cloned horse.
What is wrong with cloning horses?
The broad summary from the little data available seems to be that equine cloning is associated with high rates of embryonic loss; some incidence of fetal abnormalities (although this appears to be lower than that recorded in farm animals) and a requirement for neonatal intensive care.
Can cloned horses race?
Cloned horses cannot race in either Thoroughbred or Quarter horse races, which are the foremost racing breeds. However, Arabian horses allow cloned horses to race, and the International Federation for Equestrian Sports (FEI), permit cloned horses in Olympic sports.
How much does it cost to clone a human 2021?
Some scientists believe clones would face health problems ranging from subtle but potentially lethal flaws to outright deformity. But let’s ignore all that–for the moment–and cut to the bottom line: How much would it cost to clone a person? According to our estimates: about $1.7 million.
Can a dog be cloned?
A cloned dog is simply a genetic twin of your dog, born at a later date. The cloned twin will share many of the key attributes of your current dog, often including intelligence, temperament and appearance. The genetic identity of cloned dogs is identical to the original dogs.
Can a gelding be cloned?
The quick answer is yes. Second, cloning may prove useful in passing on the genetic material of an exceptional horse that is unable to breed. Champion geldings are an obvious choice, but fertile mares and stallions could also be chosen to start a line of cloned offspring.
Can you clone a female from a male?
As stated by others, you can clone a female from a male by doubling the X chromosome. However, this would cause any X-linked traits that the source male is a carrier for to activate. Additionally, a clone of any kind is distinguishable by having different mitochondrial DNA from the source organism.
How long do clones live for?
The closest answer is that, like natural-born humans, a clone’s lifespan varies, although they probably weren’t designed to live more than 50 human years (that would make a clone 100 years old).
What are the disadvantages of cloning?
List of Disadvantages of Cloning

- It is expected to bring about new diseases. …
- It might lead to problems in organ rejection. …
- It decreases gene diversity. …
- In-Breeding. …

Are polo horses cloned?
Polo, unlike horseracing, allows cloned animals, and they have become increasingly popular since 2013 when Cambiaso first helped his team win a match riding a clone. “It’s 70% to 80% the horse, and everyone, including Cambiaso, will tell you this.” Crestview has cloned more than 200 horses since 2009.
How much does it cost to clone a cow?
The cost to clone a cow is around $15,000, much more than the value of most commercial cows, and it will most likely be used only to reproduce elite breeding stock. Q: What is a clone? A: A clone is an organism that is descended from — and is genetically identical to — a single common ancestor.
How much does it cost to clone a dog?
The price to clone a pet in the USA costs upwards of $50,000 for a dog and $35,000 for a cat. Plus, you have to find a veterinarian willing to take a tissue sample from your pet and send it to the cloning company.
Visit the most recent news on cloning horses. Even as recently as 15 years ago, the notion of cloning horses was regarded with skepticism and distrust by the equestrian industry. However, with the advent of Dolly the sheep on 5 July 1996, this contentious science has gone a long way. The world’s first equine clone, a male mule named Idaho Gem, was born on May 4, 2003, in the American state of Idaho. The birth was heralded as “a watershed moment in the history of horse genetics and breeding.” It was Prometea, a Haflinger (seen at top right), who became the world’s first cloned foal when she was born on May 28, 2003, in Italy.
Pieraz-Cryozootech-Stallion is a product of the same team of scientists.
Typically, cloning is done in order to preserve the bloodlines of successful geldings whose sperm was not saved before to the castration procedure being carried out.
How do you clone a horse?
The donor animal’s cells are harvested for research purposes. In the case of a horse, the DNA is normally taken from the ear or the chest and put in an unfertilized egg that has had its own DNA extracted from it. An electric pulse induces the two to fuse together, as well as to initiate cell division in the process. Once the embryo has been created, it is transferred into the uterus of a host, where it undergoes a normal gestation period before giving birth to an animal that is genetically identical to the donor.

This is especially true with select, one-of-a-kind horses.
We’d love to learn more about your horse-related interests and chat with you about the possibility of cloning horses in the future.
Cloning: A new reproductive tool for equine veterinarians-dvm360
Equine breeders are exploring new techniques to shape the genetics of the equine population by breeding high-performance and defect-free animals and breeding them in large numbers. Argentine polo player Adolfo Cambiaso, who is ranked number one in the world, was profiled by 60 Minutes correspondent Leslie Stahl in March of this year, and his use of cloning to “copy” elite polo horses was televised same month. The first horse to be cloned was accomplished in 2003 with the application of technique identical to that used on Dolly the sheep, who became the first animal to be cloned from adult cells rather than embryonic cells.
As Stahl said in the piece, “Cambiaso ordered his doctor to store part of the horse’s skin cells, believing that science would advance and that he might bring Aiken Cura back to life through cloning.” Polo enthusiast Alan Meeker of Texas, who, according to Stahl, had a long-held desire of establishing a fleet of champion horses, joined up with Cambiaso to form the Cambiaso Polo Club.
- Meeker’s horse-cloning business is situated in Argentina.
- Initial attempts resulted in the birth of a foal clone of Cambiaso’s beloved Aiken Cura, who was named after the horse’s sire.
- As an extra precaution, he extracted some hair from the clone and tested it to ensure that the DNA matched that of Aiken Cura precisely.
- Cuartetera’s clones numbered in the dozens by the time he was through.
- The clones are not perfect replicas of the originals; for example, the white marks on the bodies of the Cuartetera clones are different in form and placement on the body from those on the original.
- The clones do not appear to be suffering from any particular health problems.
“We were informed that there is no proof that cloned animals experience disproportionate health issues, despite the fact that they have a little higher newborn death rate than other animals.” A60 Minutes report stated that the team of cloning experts at Cambiaso’s company now produces 100 clones every year, which they employ in their breeding business.
However, they do not sell the clones themselves, as this is a business plan that allows them to maintain the original DNA for themselves and their families.
Despite this, thoroughbreds and quarter horses are often cloned and compete in sports such as dressage, polo, and rodeo to maintain their genetic integrity.
The cloning procedure
Tailor Fit was a two-time AQHA World Champion racehorse who competed in the United States. Blake Russell provided the photograph. According to its website, ViaGen Equine is the global leader “in bringing horse cloning technology to the world’s most innovative horse owners.” The company is based in Cedar Park, Texas. ViaGen has cloned hundreds of elite horses, including the stallion Pure Tailor Fit, which is owned by ViaGen President Blake Russell. ViaGen produces cloned foals for clients all over the world, shipping horses to Europe and other parts of the world on a yearly basis.
- Horse owners and their veterinarians can produce foals that are genetically identical to the original horse through the use of cloning technology.
- Following receipt of the ViaGen kit, a veterinary practitioner performs a series of small (4- to 6-mm) biopsy punches, with the majority of the tissue being skin with a small amount of tissue below the skin.
- According to Russell, “because the procedure is so gentle, horses are frequently biopsied and then compete the same day.” The biopsy sample is then placed in a ViaGen kit and shipped to the company’s cell culture lab in Cedar Park for further processing and analysis.
- “It takes us about two to three weeks to convert the biopsy punches into a cell line of literally millions of cells,” he explains.
- The cells have a long shelf life and will continue to function well into the future.
- The oocytes can be obtained either commercially from unknown mares or in vivo by collecting them while the mare is pregnant.
- Within six days, ViaGen is able to culture the embryo in an incubator, allowing them to assess the development of the horse.
- The mare is pregnant for more than 330 days.
- Normally, these foals are kept at Timber Creek for 30 to 60 days after they are born.
This also allows for the transmission of DNA from the foal to a third party for the purpose of confirming that it is a match to the donor animal. Last but not least, the foal is transported to its owner, either with the surrogate mare or separately after it has been weaned.
An expanded genetic impact
It was just sixteen years ago that ViaGen began cloning horses, indicating that the technology was still in its infancy. The company’s goal was to clone proven breeding animals in order to assist horse owners in increasing the value of their horses’ genetics, particularly in the case of females. Exceptional mares, it was considered, had only limited capacity for contributing to the population since they can only produce one or two foals every year or two years on average.
Cloning in cattle
In the realm of food production, genomics is upending the status quo—and so is cloning, according to ViaGen President Blake Russell. Producers may identify superior animals without having to observe them during their whole productive life by using genomics, which is the examination of an animal’s DNA. Beef cattle and dairy cattle are both benefiting from this genetic technique, which is currently being employed extensively. Russell claims that it is also entirely compatible with reproductive technology like as cloning.
- “A dairy producer could have to wait years for a high-end, high-genomic cow of exceptional quality.
- That’s a section of our industry that’s growing at an alarming rate.” Geneticists have been able to detect a number of genetic abnormalities in beef cattle that have a negative impact on output.
- “ViaGen is often called upon to provide cloning services for those breeding animals that are free of the known genetic defects.” This is quite similar to what is happening with horses at the moment.
- “By mating these mares, we provide them the opportunity to contribute a greater genetic dosage to the breeding population.” “Cloning increases the impact of an outstanding mare,” Russell explains.
- Colts with an unruly disposition are frequently gelded at a young age, and some of these colts go on to have a successful performing career.
- In response to the increased number of mares and geldings increasing the size of the potential cloning market, horse business was presented with a new technology.
- Even yet, there are no assurances that you will have a champion career.
- “However, the majority of horse breeders recognize that genetics is only one component of the puzzle.
“A champion in terms of performance requires both.” Certain individuals just wish to replicate a horse with which they had a close affinity. Despite the fact that it represents a very modest share of the cloning business, ViaGen claims that it is rising in popularity.
What clients want
In the words of Gregg Veneklasen, DVM, of Timber Creek Veterinary Hospital, a ViaGen-affiliated veterinarian and expert in cloning and embryo transfer, “I believe it is critical that people understand that cloning is simply another sophisticated breeding tool.” “Even though the technology is 20 years old, there are hundreds of clones on the market today.” “Cloning has become the standard in our business, and it is another another weapon in our toolkit when it comes to horse reproduction,” he explains.
- “The process is no different from being able to do an embryo transfer,” says the doctor.
- Veneklasen’s 36-year career as a veterinarian has included a significant amount of work in the field of cloning.
- Veneklasen, and it is effective.
- Ed Kane, PhD, is a researcher and animal nutrition consultant who specializes in ruminant nutrition.
- He has worked with horses, pets, and cattle throughout his career.
On October 20, 2005, the date was changed to December 9, 2017. According to the description in the dictionary, a clone is a human who has been created from a single bodily cell of another individual. The new animal is genetically identical to the “parent” cell donor who provided the cells for creation. Previously considered a science fiction concept, the cloning of animals has become a reality in recent years, with the production of a cloned sheep in 1996 being the first example. Cows, pigs, goats, rabbits, mice, and cats were the next species to be discovered, and study in this subject is still ongoing.
- There are a number of possible responses to this question.
- Yes, that is the short answer.
- The most apparent option would be champion geldings, but pregnant mares and stallions might also be used to begin a line of cloned progeny.
- This colt, who was born in the spring of 2005, should grow up to generate sperm that will carry on the physical characteristics of his champion father to his offspring.
- Third, the procedure may be used to protect populations of rare equine species such as Przewalski’s horses and Somali wild asses, which are both threatened with extinction.
- The history of horse cloning is fascinating to learn about.
- Idaho Gem, a mule foal born in May 2003, was bred from a cell obtained from a 45-day-old mule fetus, and two additional mule clones were produced in June and July of the same year from the same cell.
Only a few weeks later, a team of Italian scientists announced the birth of Prometea, a Haflinger filly who is the world’s first living horse clone, and the world’s first live horse clone.
Cloning has been challenging in several other animals when cells from adult animals were used, probably because adult DNA has begun to age and degenerate, as has been shown in humans.
The result was the creation of a hybrid embryo.
The results of cloning research have revealed that horse oocytes do not develop properly in laboratory circumstances.
The embryos were implanted into the uteruses of surrogate mothers, where they matured into three foals who are genetically similar to each other, resulting in mule triplets.
The resultant embryo was put into the donor mare, resulting in Prometea being a genetically identical duplicate of her biological mother.
Production of a cloned mammal is a time-consuming and expensive endeavor that is fraught with a variety of difficulties.
Using the Italian team of scientists that reported Prometea’s birth as an example, they began with more than 800 nuclear-transferred oocytes, of which only 22 grew into embryos after seven days.
Prometea was the only foal that was born after being carried to term.
The mule foals raised at the University of Idaho were subjected to routine medical examinations every three weeks, as well as comprehensive blood chemistry tests every three months.
The three foals are in terrific health now that they are two years old.
In addition to them, Taz’s parents are the owners of Taz, a racing mule that has a stellar track record.
What are the ramifications of this for the horse breeding industry?
Cloned horses may perform best in sports where there are no breed limitations (such as three-day eventing), which may be the greatest venue for them to display their potential.
What is the relationship between horse cloning and human medicine?
Studies that aid scientists in their understanding of the mechanics of cell division and tissue growth may be of service to humans, albeit the results of horse studies are not necessarily relevant to studies of other animals.
Cloned Horses Have Quietly Become a Thing. Should They Be Allowed to Compete?
This winter, the world’s most elite riders will return to their seasonal home in Wellington, Florida, for three months of hunter/jumper and dressage competitions, which will be broadcast live on the internet. It is expected that the equine athletes will include those with price tags in the seven-figure range; elite international mounts flown in from Mexico, the United Kingdom, and Belgium; and a small number of cloned horses who will fly discreetly beneath the radar. s.You’re absolutely correct.
It is certain that cloned horses will be on the streets of Wellington, though the exact number is not yet known—and that is exactly how their owners want it,” says Kathleen McNulty, owner of Replica Farm, which collaborates with the Texas-based ViaGen Pets cloning service.
For many competitors, the opportunity to ultimately own and train a top-caliber horse hinges on discovering a horse with promise at an early age and then investing the time and money necessary to raise it up through the ranks yourself.
After years of hard work and hundreds of thousands of dollars invested, you learn that your investment will be competing against a fleet of imports that you paid top dollar for in Europe, as well as multiple clones of those top-dollar imports that have already proven they can compete at the highest level.
y.Shuttersto If you’re talking about reproducing show jumping superstars, science hasn’t demonstrated yet that it’s possible to do so.
In the past, no cloned horse has competed in an Olympic Games or—as far as we know—won a major Fédération Equestre Internationale (FEI) event, though this may change as more clones reach maturity (most show-jumping horses do not reach their competitive prime until they are 10 to 12 years old, and the first wave of clones produced for competition are 6 to 8 years old).
There is sufficient data to conclude that cloning does not pose the severe danger to fair play that many people formerly believed.
“You can’t expect a clone to waltz into a show ring as a six-year-old and win everything just because it has the DNA of a great horse,” McNulty explains.
“From the beginning, cloning has been utilized as a method to preserve bloodlines from champion horses in the event that they died unexpectedly, or from champion horses that were gelded early in their lives, before their worth could be determined.” However, while some people desire the ancestry, they may not like to associate it with the cloned person Mr.
- Sport-horse breeders, many of whom can trace their horses’ bloodlines back centuries, are likely to take exception to this lack of openness in modern cloning, which they believe will put them in the sights of the FDA.
- Clone of zed.Cruising Meeting; zed.Cruising Enc The image is from of Replica FarmAs cloning technology improves — which it has, according to Dr.
- On the one hand, while cloning is outlawed by major sport and breeding organizations like as theJockey Club(of Thoroughbred racing), the FEI Olympic regulatory body has permitted the participation of cloned horses in FEI competitions.
- The use of assisted reproduction procedures such as artificial insemination, surrogacy, and embryo transfer is already commonplace.
- If we remove the shroud of suspicion around clones, we will encourage more openness in competition and, as a result, we will come closer to our core goal, which is to regulate and sustain fair competition.
“It’s going to stay underground for very some time,” McNu adds. but at some point, we’re going to look back and think, ‘Oh, that was a mistake.'” rse? You mean the one who just won the top prize? Is that a clone of rix? e.’”
Scientists Cloned an Endangered Wild Horse Using the Decades-Old Frozen Cells of a Stallion
According to conservationists, the Przewalski’s horse is already extinct in the wild, with just an estimated 2,000 individuals remaining in zoos and reserves. Tanya Durrant / Flickr is licensed under a Creative Commons Attribution-Noncommercial-No Derivative Works 2.0 license. Kurt, a newborn horse that was born two months ago, is doing well. Kurt seems and behaves exactly like an ordinary foal, but he is different: he is a clone of the original. According to the Associated Press, he is the first-ever clone of his species, the severely endangered Przewalski’s horse, and represents a ray of hope for environmentalists.
- However, because the stallions and mares roaming the American West are derived from domesticated horses, they are considered feral rather than wild.
- Extreme weather, expanding human settlements, and cattle encroaching on their environment drove the horses as far east as the Gobi Desert in China and Mongolia, where they were able to survive.
- Wildlife conservationists believe that about 2,000 individuals of this species survive in zoos and reserves, including the Smithsonian Conservation Biology Institute in Front Royal, Virginia.
- Kurt’s father gave a ray of hope, pointing out that sections of his DNA were mainly absent from the other Przewalski horses, indicating that his ancestors had not reproduced as much as the others.
- A sample of the stallion’s skin cells was frozen at the Frozen Zoo at the San Diego Zoo Global in 1980 with the intention of using the stallion’s DNA to breed additional Przewalski’s horses in the future.
- “A major concept of the Frozen Zoo.
- “The Frozen Zoo.
They removed the egg’s nucleus, as well as all of the DNA contained within it, in order to create an embryo that was a clone of its father.
Kurt was born in August at a veterinary institution in the state of Texas.
For the next year, he’ll remain with his mother before being transported to San Diego Zoo, where he’ll join the zoo’s breeding herd of 14 other Przewalski’s horses.
Kurt’s birth marks a watershed moment in the conservation of the Przewalski’s horse, according to the San Diego Zoo Global.
Yet these are critical steps in the right direction.
8 Things You Should Know About Horse Cloning
Did you know that there are several hundred horse clones roaming the world, consuming food, reproducing, and even competing against one another? Cloning is no longer considered science fiction. Horse groups and federations have varying policies on whether or not clones are allowed to compete or even register with the breed in question. Here are eight things you should be aware of when it comes to horse cloning.
1 – It costs about $150,000 to clone a horse.
The sum may appear to be large, but remember that best polo ponies may get several hundred thousand dollars and that racing horses can fetch millions of dollars in the market today. A single sperm sample from a top horse may fetch upwards of half a million dollars on the open market. When it comes to folks who are producing horses that are worth millions of dollars, $150k for the genes of a proven competitive horse is an excellent investment.
2 – Cloning is becoming very popular in the sport of polo.
Because most elite polo ponies are mares, and therefore can’t be mated naturally until after they’ve retired, the sport of polo has long been a proponent of sophisticated reproductive methods. For over 25 years, embryo transfer has been the primary method of polo horse breeding. These are elite polo mares that have been artificially inseminated, and the fertilized embryos that arise from this process are subsequently put into surrogate broodmares. Cloning just adds a few more genes that are certain to be excellent.
3 – It’s becoming a popular option for continuing the bloodlines of top-performing geldings.
Because horses are often gelded to make them easier to deal with before they’ve had the opportunity to show themselves, champion lineages were formerly thought to be extinct. It is now possible to create a clone of the champion in order to pass on the champion’s DNA. While the clone is unlikely to compete due to the fact that gelding him would be counterproductive, his descendants may be able to.
4 – Clones can’t be registered with the American Quarter Horse Association.
In addition, several other horse organisations have prohibited the registration of clones on the basis that they do nothing to further the breed’s development.
5 – In 2012, the FEI changed its rules to allow clones to compete.
The Fédération Equestre Internationale (FEI) is the worldwide regulatory organization for all equestrian disciplines, including those used in the Olympics. Because they wanted to foster the preservation of the genes of outstanding geldings, they decided to allow clones to participate in order to increase the likelihood that clones would appear at the Olympics.
6 – The success rate is only around 12%.
To secure the successful delivery of even one clone, it is necessary to generate a dozen embryos and impregnate three or four broodmares over the course of many months.
7 – Birth defects, some severe and even fatal, are not uncommon.
Various sources indicate that at least 5 percent and as many as 50 percent of all clone foals are born with birth abnormalities, with some estimates reaching as high as 80 percent.
8 – The sample must come from a live horse.
The present procedure involves taking a sample of cells from a horse’s neck, swapping the nucleus of one of those cells into an equine egg, and then shocking the egg to encourage development before it is implanted into a broodmare. (Images courtesy of Vanity Fair, CNN, and the Los Angeles Times)
Equine cloning: applications and outcomes
Cloning is one of several novel assisted reproductive procedures being explored for therapeutic application in the horse industry. Cloning is a technology that has been around for a long time. Equine cloning may be used for a variety of purposes, including: (1) the preservation of genetic material from individual animals that would otherwise be unable to reproduce, such as geldings; (2) the preservation of genetic material from endangered and/or exotic species, such as the Mongolian wild horse (Przewalski’s horse); and (3) because horses serve as a companion animal for many people, it is likely that some horse owners will have individual horses cloned to provide emotional fulfillment.
Despite the fact that horse cloning has proven successful, as has been the case with other animals, it remains a relatively inefficient procedure (3 percent success).
In some species, the inefficiency of cloning is due to a high incidence of embryonic, fetal, and/or placental developmental abnormalities, which contribute to extremely high rates of embryo The current review describes some of the ultrasonographic, endocrinological, and histopathological characteristics of successful (produced viable offspring) and unsuccessful (resulted in pregnancy failure) cloned equine (mule and horse) pregnancies that we have successfully produced in the laboratory.
Twenty-one cloned mule pregnancies were created utilizing fetal fibroblast cells, whereas seven adult cumulus cell-based cloned horse pregnancies were established using fetal cumulus cells.
When combined with other information, this information contributes to an ever-growing body of knowledge on the fate of cloned horse pregnancies that will aid in determining when, and probably why, many cloned equine pregnancies fail.

An Inside Look at Equine Cloning
Margaret Evans contributed to this article. Earlier this year, a survey on the Canadian Horse Journal website raised the question: Should horses be cloned? The results were mixed. In response to the question, 83 percent of respondents responded no, not until additional study has been done; 15 percent said maybe, in specific circumstances with stringent limitations; and just two percent said yes, and that registration of clones should be permitted. Cloning, once the darling concept of science fiction writers, made its triumphant return to the world stage on February 22, 1997, when it was announced that Dolly the sheep, a ewe cloned at the Roslin Institute in Midlothian, Scotland, had been born on July 5, 1996, after being cloned at the Roslin Institute in Scotland.
- She was a resident of the Institute until her death there in 2003.
- Along came “twins” of a variety of animals, including cats, rats, deer, cattle, fruit flies, rabbits, and other species.
- Immediately after, two cloned “siblings” were born, the first of whom was Utah Pioneer on June 9 and the second of whom was Idaho Star on July 27.
- Prometea was a Haflinger foal born on May 28, 2003, at the Laboratory of Reproductive Technology in Cremona, Italy, and was the first of its kind.
- After Scamper, a champion barrel racing gelding, was cloned and his “twin” stallion was born, he became the first cloned horse to stand as stud in the United States in 2006.
- Nevertheless, what exactly is cloning, and is the cloned horse a literal copy of the original animal?
Katrin Hinrichs, professor and Patsy Link Chair in mare reproductive research at Texas A&M University’s College of Veterinary MedicineBiomedical Sciences, “we take advantage of two factors.” ‘For starters, the nucleus of every cell in the body possesses the identical DNA, which codes for the production of the complete animal.’ Two, the oocyte (egg) is ready to be fertilized and is filled with everything that will be required for the embryo’s growth during the first three to four days after fertilization.
- The fundamental method is simply a variant on what occurs naturally during fertilization.
- The egg then begins to grow into an embryo once it has received a complete set of DNA.
- “After that, we signal to the egg to begin developing into an embryo.” A cloned embryo that has progressed to the point where it may be successfully transplanted into the uterus of a recipient mare is known as a recipient mare embryo.

“Occasionally, the placenta does not function as well as it should,” she continues, “and this might have an impact on the health of the foal at birth, causing it to be weak or to have a big umbilical chord.” However, while though cloned horses are exact replicas of their original counterparts, this does not imply that they can perform the same functions as their original counterparts, who are commonly referred to as “twins.” If the foal was born weak or with crooked legs (as can happen with any normal foal due to its position in the uterus or the pliability of the membranes around it), the foal may not have the athletic abilities of the original horse.
If the foal was born weak or with crooked legs (as can happen with any normal foal due to its position in the uterus or the pliability of the membranes around it), the foal may not have the athletic abilities In addition, the animal’s habitat, handling, management, and training all have an impact on its athletic abilities.
- According to Hinrichs, there have been no tests conducted to yet to determine how similar the cloned horse is to its original twin in terms of physical characteristics.
- That just isn’t a viable option.
- So what’s the point of cloning?
- In addition, we are reproducing bloodlines from superb, established stallions and are generating comparable numbers from each gender.
- It has been providing horse cloning services for the past 13 years.
- The most common motivation for cloning is to maintain the unique DNA of a great equestrian athlete, whether they compete in show jumping, polo, or barrel racing, as well as to improve their performance.
- While mares can be bred, geldings, on the other hand, are not allowed to reproduce.
“Cloned horses are capable of reproducing,” adds Hinrichs.
One of the most frequently cited reasons for cloning is the fact that an outstanding champion horse is a gelding.
During the first several days after Prometea was born, the researchers experimented with 841 rebuilt eggs to see what would happen.

“When ViaGen first began offering horse cloning services, equine embryo technology was still primarily focused on the use of fresh embryos.
We at ViaGen have been successful in developing high-quality embryo freezing technologies, and today we cryopreserve and export all of our horse embryos to one of our embryo transfer centers.
Russell claims that several of the research facilities were having difficulties with foal health in the short postpartum period.
However, success rates are now quite high, with healthy cloned foals being produced that do not require any particular attention or treatment.
It’s understandable that cloning raises some eyebrows.
But does the fact that you can do something imply that you should?
On the other hand, there is a legitimate concern that the incidence of sickness may result in genetic mutations, and that recurrent breeding for a certain line and/or discipline could result in a genetic bottleneck, putting the breed’s healthy variety at danger.
The Jockey Club will not register a cloned Thoroughbred, nor will it register any horse created by any technique other than live cover, in fact, the club will not register any horse at all.
“The owner was successful in the United States Federal Court,” adds Russell.
So the American Quarter Horse Association is permitted to maintain its prohibition against the registration of cloned Quarter Horses and their descendants.” In contrast, Russell says that most international registries have approved the registration of genetically modified horses and the offspring of genetically modified horses, and that cloning technology is simply another breeding tool that should be used responsibly by breeders to achieve their performance goals.
- “ The decision of the American Quarter Horse Association does not appear to be having much of an influence on the decisions of other registries across the world.
- Most competitions, other than horse racing, are open to foals that have been bred using cutting-edge breeding procedures.
- In the case of valuable geldings, or in the case of rare or endangered species or breeds, “the major argument I see for cloning is to maintain genetics so that you may spread the gene pool,” says Hinrichs.
- For almost 40 years, scientists at the San Diego Zoo Conservation Research Center’s Frozen Zoo have been storing genetic material from endangered animals in liquid nitrogen.
- In addition, 381 females from 177 different species have their oocytes (eggs) cryopreserved for use in fertilization and embryo transfer experiments.
- As an illustration, their researchers were able to achieve successful fertilization by injecting the oocytes of the endangered southern white rhinoceros with sperm that had been stored for more than two decades.
- Gemini was born on September 15, 2008, at the Cryozootech facility in France.

In order to conduct research studies, banked DNA and tissue samples are maintained for future use.
Genetic barcodes make it possible to identify the species that are used in the manufacture of bags, shoes, or meat that is sold at urban markets, which aids in the fight against illegal wildlife trade and poaching.
It is possible to clone horses whose DNA has been maintained for as long as 20 years, thanks to the hundreds of animals represented in our cryopreservation bank, according to the researchers.
When the frozen sperm supply is insufficient or the mare is unable to achieve a pregnancy on her own, a technique known as equine intracytoplasmic sperm injection (ICSI) can be used to supplement the mare’s sperm supply.
The cloning path, according to him, paves the way for more convenient future techniques of reproduction, such as artificial insemination (AI) or natural service.
“We find a similar situation with older, elite mares,” says the author.
Russel explains that his company is now providing their horse cloning service for $85,000.
It is possible to pick up the foal and recipient mare together at 60 days of age, and then subsequently return the recipient mare after the foal is weaned, according to ViaGen’s policies.
The foal and recipient mare will be held for up to 60 days at ViaGen’s facility for inspection, but many of our clients want to take them home sooner so that they may grow them in their own management system.” Over the previous 10 years, ViaGen has demonstrated that it has a successful track record with each cell line tested.
A simple biopsy sample collected by their doctor is the initial step for breeders who are considering cloning their animals.
Cells from the biopsy sample are grown in culture and, once they have reached maturity, they are cryopreserved for future use.
The tissue of a horse that has been euthanized, on the other hand, cannot be harvested.
How ViaGen’s technology works How Blake Russell Began His Cloning Career Vice President and Chief Operating Officer Blake Russell was raised in the Quarter Horse racing industry and spent his formative years around horses.
They collaborated with a group of experienced horsemen to compile a list of outstanding performers who possessed elite pedigrees but were unable to reproduce.
Because his owners were more interested in racing than breeding, he was gelded as a yearling to ensure a successful racing career for him.
Tailor Fit went on to win the AQHA World Racing Championship twice more, earning well over a million dollars and earning a speed index of 110 in the process.
Russell claimed that a glance at his pedigree revealed that those characteristics were not the result of chance, but were the result of a superior set of genes.
It’s a true Tailor Fit.
His athleticism is out of this world, and his charismatic personality draws everyone’s attention to him as the main attraction.
We are quite optimistic about their future since they appear to possess the characteristics that motivated us to go on this adventure in the first place.” Pure Tailor Fit is a cloned horse that is owned by Blake Russell, the President of ViaGen, a Texas-based biotechnology company.

‘Fit’ or one of his offspring confirms our decision to bring this pedigree back into production with each passing day.” People are frequently perplexed by the concept of cloning and fail to appreciate the significance of identical twins.
When it comes to breeding value, Pure Tailor Fit is exactly the same as Tailor Fit would have represented if he had been allowed to remain intact and produce offspring.
Using cloning technology, ViaGen Equine is cloning elite horses for Olympians, world-class breeders, and owners of the world’s best equine athletes.
