- A rig is an entire male horse with no signs of external testicles so appears to be a gelding; but one or two testicles are still present, producing testosterone. Some geldings still show stallion-like behaviour despite being fully castrated; they are called “false rigs”. Find out all about it here. Likewise, how can you tell if a horse is a rig?
How can you tell if a horse is a rig?
A rig is an entire male horse with no signs of external testicles so appears to be a gelding; but one or two testicles are still present, producing testosterone. A rig behaves like a stallion and, potentially, may be fertile.
Can a rig impregnate a mare?
In normal horses, the testicles develop close to the kidneys and migrate through the abdomen, down through the inguinal canal to their normal position in the scrotum. However, rigs can produce sufficient sperm to impregnate mares, particularly if only one testicle is affected.
Can a rig horse be fixed?
This condition can be corrected by surgery to place the testicle in the correct position, but most ridglings are gelded to remove the testicle altogether. There are blood tests that can determine if a horse is producing male hormones, though these do not detect a ridgling if hormone levels are too low.
How does a horse become a rig?
A horse that has had both testes removed but still exhibits overt masculine behaviour is sometimes called a false rig. False rigs are often attributed to a horse which is “proud cut”, that is part of the epididymis is left behind at castration; however, the epididymis is unable to produce the hormone testosterone.
Does rig calm work?
This calming formula works quickly and is particularly useful for colts, stallions and geldings who display too much interest in mares. RigCalm promotes relaxed and good behaviour, assists performance and handling and helps to reduce aggressive behaviour.
Can a rig sire a foal?
it is rare for rigs to sire foals for the reasons galadriel put, but it is definitely possible.
What is a false rig?
A false rig is an aggressive gelding that displays male dominance-type behaviour, despite having both testicles removed. The stallion-like behaviour displayed by false rigs is not driven by testosterone, and can only be controlled by the correct management techniques.
What is a rig calf?
Rig is a common English word for a partially castrated male livestock animal. It is also a Scots word for the runt of a litter.
What is proud cut?
Traditionally, the term ‘proud-cut’ implies that a part of the epididymis (sperm storage site located adjacent to the testes) was left in the horse at the time of castration. Normally each testis and associated epididymis is removed during castration. Testosterone is produced by cells within the testes.
Why does my gelding get erections?
It may be that overstimulation of the dopamine pathway is causing the horses to become hyperaroused. Alternatively, spontaneous erections have been cited in the literature as a comfort behaviour, and Franzin has considered that dropping may simply be a sign of relaxation.
What do you call a stallion with one testicle?
A cryptorchid horse, or ‘rig’ as it is commonly known, has one or both testicles retained in the inguinal canal or abdominal cavity.
What do you call a female baby horse?
The gender-neutral term for a baby horse is a foal. A female is called a filly and a male is called a colt.
Is gelding a horse cruel?
Gelding them allows them to be in the general population of the rest of the horses, rather than be secluded for fear of aggression or pregnancy. People choose to geld or not geld for different reasons, but it’s not cruel.
Why do they cut horse’s balls off?
Why are horses castrated? Most male horses are castrated for convenience in order to eliminate or reduce male behaviour such as aggression and uncooperativeness in those horses that are not intended for breeding purposes.
What does gelding mean in horses?
A gelding is a castrated male horse, donkey, or mule. Unless a horse is to be used for breeding purposes, it should be castrated. Gelding can make horses more even-tempered and easier to handle. A stallion who is gelded later in life may retain more aggressive stallion-like behavior.
When is a gelding actually a rig?
- According to the USDA, “In general, alfalfa has more energy than other grass hays, which is why it has a negative reputation.” Having too many calories is a waste of resources. The lack of sufficient physical activity for your horse might, in certain cases affect his behavior and cause him to become hyperactive. The same impact would be achieved if Cubitt gave him too much grain and didn’t exercise him, he added. For a hard keeper, Alfalfa is especially beneficial because of its great palatability—horses adore the taste of the plant. A horse’s diet can be supplemented with alfalfa instead of excessive concentrates in order to increase the number of calories available. According to the USDA, “Alfalfa hay is often lower in fiber and higher in calories than grass hay, as well as richer in protein and calcium.” According to Lawrence, because alfalfa is stronger in calories and protein than most other crops, “consuming alfalfa makes it simpler to achieve those demands with minimum, or at least reduced doses of supplementation.” With its high calcium content, alfalfa must be provided with consideration for the calcium-to-phosphorus ratio in the diet. In contrast to grass hay, feed concentrates (particularly rice bran) have lesser quantities of calcium and phosphorus whereas grass hay has larger amounts of calcium and phosphorus. The optimal calcium to phosphorus ratio in horses is a 2:1 ratio, however in adult horses, the ratio can safely be increased to as high as 5:1 without causing any negative consequences. Visit the website of Susan Evans Garlinghouse, DVM, for further information on the calcium-phosphorus ratio. For my horse, what type of Alfalfa is best. A large number of farms on the West Coast of the United States feed just alfalfa without encountering any difficulties. It is preferable to combine alfalfa with high-quality grass hay and fodder from healthy pastures, though. It is possible to get mixed hay with great nutritional quality in both the alfalfa and grass, but because alfalfa grows sooner in the spring than grass hay, it is more difficult to locate mixed hay with excellent nutritional quality in both the grass and the alfalfa. If you’re considering using alfalfa in your forage feeding program, Cubitt recommends starting with the highest quality grass hay you can get and supplementing with alfalfa at meal times to get the most nutritional value. Instead of hay, if you can’t get excellent quality baled alfalfa, alfalfa pellets or cubes can be used instead—1 pound of pellets or cubes is the equal as 1 pound of hay in terms of nutritional value. Although late-cut alfalfa, which is harvested when the plant is budding but before it blooms, is the most nutritious because the amount of protein and total digestible nutrition in mature alfalfa decreases as the plant grows. It is also more palatable than late-cut alfalfa because it is green and has less fibrous stems than late-cut alfalfa. In the case of a horse that does not require the high quantities of protein and energy provided by alfalfa, feeding a late maturity cut of alfalfa is the most appropriate option to consider. Any circumstance necessitates arranging your horse’s forage ration with a careful eye on his overall ration, calculating his protein and energy requirements, and then supplying those requirements with suitable grain and forage. Stomachs are also soothed by this remedy. Alfalfa hay has been demonstrated in new studies to have the potential to buffer stomach acid, which can reduce the severity and occurrence of ulcers in addition to being a good calorie and protein source. Twelve horses were fed a pelleted concentrate and Bermuda grass hay in one trial, whereas twelve other horses were fed the same pelleted concentrate and alfalfa hay in another study conducted by Texas A&M University As a consequence of a stomach endoscopy, each horse in the trial was awarded a gastric ulcer score before to the study’s start. The ulcer severity ratings of the horses fed alfalfa had decreased overall by the conclusion of the research, but the ulcer severity scores of the horses given Bermuda grass hay had increased. It is estimated that more than 80% of all performance horses suffer from ulceration to varied degrees. According to Cubitt, “alfalfa is abundant in calcium, which has a buffering effect on acid in the stomach.” “Incorporating a small amount of alfalfa into your diet, especially before exercise, can significantly reduce stomach acid production.” A horse who would not normally require alfalfa in his diet (for example, an easy keeper) but who has a history of ulcer issues can benefit from alfalfa supplementation. It doesn’t hurt to give him a little alfalfa in his hay net before a stressful circumstance, whether it’s trailering or competing. If you give him a handful of alfalfa around 30 minutes before riding or trailering, he will be less acidic in the future. “If cubes or pellets are more convenient for you, that’s OK,” Cubitt said. ” The Legends of Alfalfa So, what is it about alfalfa that has such a terrible reputation among horse enthusiasts? Some people are concerned that feeding alfalfa increases the risk of colic in infants and children. Lawrence, on the other hand, is not of this opinion. In addition, she noted that “rapid diet changes have been linked to colic,” so it’s probable that switching from grass hay to alfalfa hay all at once, or bringing in alfalfa hay all at once, will raise the risk of colic. Also, when excellent grade alfalfa is fed ad libitum, horses may overindulge, which may raise the risk of colic in the horses.” “For example, if a landowner want to plant alfalfa, he or she may follow the following two guidelines:” 2. Limit or at the very least monitor consumption to avoid overeating.” 1. Make the switch to it gradually. 2. Because of its high protein content, there is also a widespread belief that alfalfa might cause renal disease. An ancient wives’ tale, most likely based on the fact that horses with a high protein intake tend to drink more water and pee more frequently than their counterparts. Nitrogen is produced as a consequence of the body’s process of converting protein into energy, and it is filtered out of the body by the horse’s kidneys. In order to help in the filtration process, a horse that is converting surplus protein to calories will drink more water, which will result in urine that has a strong ammonia smell, since the nitrogen is expelled in the form of urea. The extra protein, on the other hand, has no negative impact on renal function. There is a popular belief that alfalfa hay would make a horse hot and agitated or even insane. In addition, this isn’t correct. Alfalfa, on the other hand, has a substantial quantity of calories, and an excess of calories in any form, whether from alfalfa, grain, or oil, combined with a lack of activity can result in an overly active horse, according to the American Horse Council. Alfalfa given with a careful eye to the proportions of the entire diet as well as the energy requirements of the horse will not provide surplus energy for the animal. Take a look at Part 1: You Don’t Need a Ph.D. to Solve the Protein Puzzle for more information. To continue reading, go to Part 2: Feeding a Hard Keeper Requires Extra Calories and Patience.
Ridgling – Wikipedia
“In general, alfalfa has more energy than other grass hays, which is why it has such a terrible reputation. Excess calories are converted into energy. Yes, if you don’t give your horse enough exercise, it might affect his demeanor and cause him to become a little hyper. “However, if I overfed him and didn’t exercise him, it would have the same impact,” Cubitt explained. Alfalfa is particularly beneficial for a difficult keeper because of its excellent palatability—horses adore it. Giving alfalfa is a great alternative to feeding excessive concentrates to a horse in order to increase the amount of calories in his diet.
According to Lawrence, because alfalfa is stronger in calories and protein than most other crops, “consuming alfalfa makes it simpler to achieve those demands with minimum or at least reduced doses of supplementation.” Given its high calcium content, alfalfa must be provided with consideration for the calcium-to-phosphorus ratio in the diet.
- (See also: The optimal calcium to phosphorus ratio in horses is a 2:1 ratio, however in adult horses, the ratio can safely go as high as 5:1 without causing any detrimental effects.
- The Best Alfalfa for My Horse – Which One Should I Choose?
- The optimum condition, on the other hand, is to combine alfalfa with high-quality grass hay and excellent pasture fodder.
- If you’re considering using alfalfa in your forage feeding program, Cubitt recommends starting with the highest quality grass hay you can get and supplementing with alfalfa at meal times to achieve the greatest results.
- Early-cut alfalfa, harvested when the plant is in the process of budding and before it blooms, is the most nutritious since the amount of protein and total digestible nutrition in the plant decreases as the plant grows.
- In the case of a horse that does not require the high quantities of protein and energy provided by alfalfa, feeding a late maturity cut of alfalfa is recommended.
- It also has stomach-soothing properties.
A research conducted by Texas A&M University compared the performance of 12 horses fed a pelleted concentrate and Bermuda grass hay to 12 horses fed the same pelleted concentrate and alfalfa hay.
At the conclusion of the trial, the ulcer severity ratings of the horses given alfalfa had decreased overall, but the ulcer severity scores of the horses fed Bermuda grass hay had increased.
According to Cubitt, alfalfa is abundant in calcium, which has a buffering effect on the acid in the stomach.
If you have a horse that would not normally require alfalfa in his diet (for example, a horse who is easy to keep), but who has a history of ulcer issues, alfalfa may be useful.
A quarter-hour or so before he’s ridden or trailered can assist keep his stomach acid from being too acidic.
Alfalfa and Its Legends So, why has alfalfa received such a poor rap among horse owners?
Lawrence, on the other hand, does not believe this.
“As a result, if a landowner wishes to plant alfalfa, he or she should follow two rules: 1.) Introduce it gradually, and 2.) restrict or at the very least monitor intake to avoid overeating.” There is also the misconception that alfalfa, because of its high protein content, can cause kidney damage.
Nitrogen is produced as a byproduct of the body’s process of converting protein into calories, and it is filtered out of the body by the horse’s kidneys.
The excess protein, on the other hand, has no negative effect on the kidneys.
This is also untrue.
Alfalfa fed with a careful eye to the proportions of the entire diet as well as the energy requirements of the horse will not produce excess energy. Part 1: You Don’t Need a Ph.D. to Solve the Protein Puzzle Continue reading Part 2: Feeding A Hard Keeper Requires Extra Calories and Patience.
When it comes to dogs, the toy and small varieties are regarded to be the most vulnerable. A puppy’s testicles typically drop by the time the puppy reaches the age of 40 days.
The rate at which testicles descend varies between individual horses, but horses over the age of three years with the condition are generally castrated (or removed). To remove the retained testicle, a treatment known as a cryptorchidectomy is performed; however, multiple methods are employed depending on where the testicle is located within the body cavity. In most cases, an undescended testicle does not pose a major or life-threatening hazard to the animal, however it may cause pain at times.
- Cryptorchidism is suspected when an otherwise healthy male horse shows aggressive or sexual behavior while being regarded as a gelding.
- A horse that has been partly castrated is an alternative definition of ridgling.
- As a result of the castration treatment, such animals may display sexual behavior that is comparable to that of intact males, either because the undescended testicle finally sank into the scrotum or because the retained testicle may still generate some hormones.
- There are blood tests that may be used to assess whether or not a horse is generating male hormones; however, if the horse’s hormone levels are sufficiently low, these tests will not detect a ridgling.
- Occasionally, true geldings will display aggressive or stallion-like behavior, which is referred to as “false rigging,” but this behavior is not caused by hormones and can horse addressed with proper training and discipline in some situations.
- Ridgelings can affect horses of any type, however Quarter Horses, Saddlebreds, Percherons, and pony breeds appear to be more susceptible to the problem than other breeds.
- Upon reaching puberty in a young male animal, the testicles, which were initially located within the abdominal cavity, are transported down theinguinal canal and into the scrotum.
- When a horse is 16 months old, both testicles have usually dropped, but as many as 15% of all male horses between the ages of two and three years may have a retained testicle, according to the American Horse Society.
While the horse was gelded because the undescended testicle was causing him noticeable discomfort and his manners improved as a result of castration, his success in horse racing has sparked considerable debate about whether it would have been better to opt for surgical correction of the condition rather than castration.
Indy, and Slew o’ Gold, were ridglings during the time.
There is disagreement about whether or not to remove an astallion’s undescended testicle; some individuals feel it causes discomfort to the animal, while others disagree with this.
The removal of the non-functional testicle has been shown to improve the disposition and athletic performance of some stallions. Due to the fact that they only have one testicle, these animals are frequently referred to as monorchids, yet they are normally fertile.

- A rig is a complete male horse that seems to be a gelding since there are no evidence of external testicles
- Yet, one or two testicles are still intact and generating testosterone, resulting in the appearance of a gelding. A rig acts similarly to a stallion and, in some cases, may be fruitful. It is necessary to castrate them because of their unpredictable behavior and the threat they might provide to anybody handling them. Although they have been castrated, some geldings nevertheless exhibit stallion-like behavior, which is referred to as “false rigging.” In these situations, behavioral therapy is the only available therapeutic option.

Rigs, Ridglings or Cryptorchidism in Horses And Why It’s a Problem
You may have heard the phrase ‘rig’ or ‘ridgling’ when someone is talking about a horse that behaves like a stallion but is actually a gelding, which is referred to as a rig. Cryptorchidism is thought to be the source of this behavior. Cryptorchidism refers to the fact that, despite the fact that a horse cannot procreate, it still produces testosterone, and as a result, the horse will behave as if it were a stallion. One of the finest pieces of advise for anybody purchasing their first horse is to avoid buying a ridgling since the horse’s stallion-like temperament may necessitate management that is beyond the ability of an inexperienced rider or owner.
Afoal’s growing testicles exit the abdominal cavity and pass via the inguinal canal, which is a tunnel in the abdominal wall through which blood vessels, tubes, and ligaments flow, to reach the scrotum throughout the foal’s prenatal development and development. Normally, both testicles drop and everything is well, however in rare occasions, one or both testicles may not descend. As the vaginal rings at the base of the inguinal canal close, the inguinal canal becomes constrictive (usually about two weeks after birth).
The testicles may remain high in the abdominal cavity or within the inguinal canal, depending on the situation.
It is possible that this will occur for a variety of reasons, which are discussed in detail below.
A rig or a ridgling will behave in a stallion-like manner while they are young. Beginners will find them inappropriate, while experienced riders will find them to be a challenge in some cases. The horse may be significantly more temperamental than a stallion, some believe, due to the fact that descended testes do not operate in the same manner as regular testes do. The horse may alternatively be gentle and aggressive, some believe.
Cryptorchidism is frequently overlooked until it is too late to geld an acolt. Because the testicles might be confused for other tissues within the scrotum, it may be necessary to consult with a veterinarian to confirm a diagnosis. In most cases, all that is necessary is palpation of the scrotum externally and internally via the rectum. It is possible that the horse will need to be tranquilized for this extremely invasive interior examination.
When a ridgling has two undescended testes, he may be mistaken for a gelding if the testes cannot be found by palpitation, which is rare. If this is the case, a blood test can be performed to determine whether or not testosterone is present.
Cryptorchidism is a condition in which a horse exhibits stallion-like behavior. The undescended testicles only seldom generate viable sperm, although they do continue to produce testosterone in little amounts. The stallion-like demeanor of some ridglings makes it tough to cope with the youngster. A ridgling may not be the greatest choice if you are seeking for an all-around pleasure horse. Some ridglings are capable of reproducing and are thus retained for the purpose of breeding. There is a great deal of debate around this since many people believe that if there is a hereditary component to the disorder, it should not be passed on to future generations.

It can be expensive to have surgery to remove or “geld” a ridgling due to the fact that it entails more complicated operations than gelding. However, rather than costing roughly $250 to geld your horse, the cost might go as high as $1000, depending on where the testicles are kept in the abdominal cavity of your horse. If the testicles are located in a difficult-to-reach location in the belly, the examination and operation will be quite expensive. The laparoscopy procedure has been the most often performed type of surgery.
Despite the fact that the procedure itself is not particularly invasive, it does necessitate the use of specific equipment and training.
Because of this, many rigs are not gelded, or if they do, they are just partly gelded if they have only one testicle descending.
Aside from avoiding cryptorchidism, there is nothing that can be done. Because many people believe — though there is no substantial evidence to support this — that it is inherited. Furthermore, many people think that cryptorchids that are capable of reproducing should not be utilized for breeding reasons. Although there are a variety of reasons why cryptorchidism arises, the argument goes, unless there is evidence that it is genuinely genetic, it is permissible to utilize them as breeding material until there is proof that it is genetic.
Always consult your veterinarian for health-related inquiries, since they have evaluated your pet and are familiar with the pet’s medical history, and they can provide the most appropriate suggestions for your pet.
What Is A Rig Horse?
What Is a Rig Horse and How Do I Use One? Is it possible for a rig horse to get a mare pregnant? The rigs are completely sterile. So, unless she has had access to a stallion, it is possible that she should be examined by a veterinarian. Just though she is passing a lot of feces does not rule out colic as a possibility. In horse racing, what exactly is a rig? A rig is a male horse that has a testicle that has not descended into the scrotum and is therefore considered to be healthy.
A surgical procedure is required for the gelding of a rig. What is the name of a horse that has no balls? a cryptorchid, often known as a ridgling, is a male horse whose testicles do not descend into the scrotum, or one or both of them do not.
What Is A Rig Horse – Related Questions
According to tradition, the phrase ‘proud-cut’ refers to the fact that a portion of the epididymis (a sperm storage location located near to the testicles) was left in the horse after castration was completed. During castration, the testicles and related epididymis are typically removed one at a time.
What is the usual lifespan of a horse?
Horses have a long life expectancy. Horses have a life expectancy of 25 to 30 years on average.
Can a gelded horse still get hard?
Many totally castrated geldings will still be able to erection, mount, insert, thrust, and ejaculate after being castrated, especially if they are allowed access to females in estrus on a pasture-free basis.
Do geldings still mount mares?
Unusually in veterinary practice, the complaint of the male who behaves like a stallion is rather often. In addition to mounting mares and acting possessive of mares in a band, these geldings are capable of having an erection and pursuing mares even when being ridden. The horse should not become pregnant after having been properly castrated.
How many mares can a stallion breed in one day?
In a single day, how many times can a stallion reproduce? While let out with mares for pasture breeding purposes, a stallion will mate considerably more than twice or three times each day on average. Successful breedings for a stud that is at least 2 years old and has had a few breeding seasons will be able to cove 2 to 4 mares in a single day if the stud is of mature age.
What do you call a female race horse?
In most circumstances, a mare is a female horse older than three years of age, while a filly is a female horse three years of age or younger in most cases. The term “mare” refers to a female horse that is more than four years old while competing in Thoroughbred horse racing. A stallion is a male horse that has not been castrated, whereas a gelding is a male horse that has been castrated.
What’s the name of a female horse?
Form and function are intertwined. The male horse is referred to as a stallion, and the female horse is referred to as a mare.
What does it mean when a horse gets gelded?
In the case of a male horse, castration is a surgical process that is done by a veterinarian and is defined as the removal of the horse’s testicles. When the horse is resting on its side, the treatment can be performed under general anesthesia with sedation and local anesthetic (lateral recumbency).
What is H in horse gender?
What does H stand for in horse gender? Quora is a question and answer website. It actually stands for “horse,” believe it or not. In Thoroughbred racing, a horse is defined as a male that is five years old or older and who is in good health. If he is younger than two years old, he is a colt. A mare is a female horse that is 5 years old or older; a filly is a female horse that is younger than 5 years old.
Why do they cut horse’s balls off?
Keeping stallions among other horses, particularly mares and other stallions, may be a challenging task. So much so that some stables don’t even allow stallions, or if they do, they are kept apart from the rest of the horses. This is why many male horses are gelded (had their tests removed) to avoid these behavior concerns from developing.
How do I know if my horse is proud cut?
When a horse has been gelded yet continues to behave like a stallion, it is referred to as a “proud cut.”
How long after gelding can you ride?
Although horses may and should be trained starting the day following castration, it is not recommended to plan anything rigorous until the surgical site has healed completely.
Aside from regaining his power and vigor, the horse will also entirely recover during the healing process, which will take around two weeks.
What age should you geld a horse?
Horses attain sexual maturity, often known as puberty, between the ages of 18 and 24 months. Most people wish to geld their horses before that time if they know they are not going to maintain them as stallions. I’d guess a year at the most. Most veterinarians would recommend six to twelve months since it is actually much easier to treat patients when they are younger.
What breed of horses live the longest?
The Arabian, Appaloosa, Haflinger, and American Paint Horses are the horse breeds that appear to live the longest, however it is the care that the horse receives that is more significant than the horse’s breed.
What is the oldest horse ever?
One of the oldest horses ever was named Old Billy; he was born in Woolston, Lancashire in 1760 and died at the age of 62, making him the world’s oldest horse.
Is gelding cruel?
In no way, shape, or form. In fact, in many circumstances, it helps to rid the horse of a great deal of stress. Gelding them permits them to be included in the main population of the other horses, rather than being separated from the rest of the herd due to fears of hostility or pregnancy. Grooming is done for several purposes, and it is not considered harsh in any way by any means.
Why do horses fall after mating?
Horses are prone to syncope. This is most likely a fault in the cardiovascular system. It also has the potential to cause cardiac arrest. Some stallions that are gelded late may also have this condition, which is most likely connected to their heart in the majority of cases. The same is true for fainting after mating with a mare, which is ascribed to cardiac difficulties.
Do horses run better after being gelded?
The gelding of a horse has no effect on the horse’s highest possible speed. It is impossible to modify a horse’s genetic composition in terms of how fast it is capable of running. A horse’s speed may be increased simply by boosting its ability to concentrate, which allows the horse to reach its maximum speed more rapidly.
Can a gelding bring a mare into season?
Absolutely not — it is a common misconception that a stallion or gelding can “bring” a mare into season, which is just untrue. When humans interfere pharmacologically or there is anything unusual going on, such as an illness or prolonged CL, mares will do their own thing and cycle at their own rate.
How many times should you serve a mare?
I personally like to follicle test, and serve once. Others do not do a follicle test and instead serve once everyday for at least two days, followed by a day off before serving one more if the mare agrees. Alternatively, one breeder serves TWICE a day for three days (poor mare!) in another setting.
How long does sperm live in a mare?
When sperm is supplied through a live cover, we should anticipate it to remain in the mare’s uterus for up to 72 hours. In contrast, with artificial insemination, we may anticipate sperm to survive in the mare for just around 24 hours.
An Equine Rig, Cryptorchid. What is it and How to Manage it
Dr. Peter Gillespie, BVSc, MACVS, is a veterinarian. One or both of the cryptorchid horse’s testicles are kept in the inguinal canal or abdominal cavity, as is the case with a rig, as is the case with a rig (Fig 1). Often, the problem stays undiscovered until the horse is castrated, at which point it becomes obvious. It is believed that the testicles are positioned in the abdominal cavity, just below the kidneys, during early foetal development. As the foetus develops, it begins to descend towards the inguinal canal, where it finally passes through and into the scrotum during the last weeks of pregnancy.
- Cryptorchids are classified as either abdominal or inguinal cryptorchids, depending on where the retained testicle is located in the body.
- Let’s take them one at a time and examine them.
- It can also be classified as either a temporary or a permanent retention depending on the circumstances.
- This ailment normally involves just one testicle and in 75 percent of instances, it is the right side.
- If the horse is allowed to develop normally, the retained testicle will eventually descend into the scrotum by the time it reaches the age of three.
- When a horse exhibits this form of retention, it is sometimes referred to as a “high flanker.” Once again, this illness normally affects just one testicle, although both the right and left testicles are afflicted equally.
- When the testicle remains in the abdominal cavity, this condition is referred to as abdominal retention.
When both the testicle and the epididymus are kept within the abdomen, this is referred to as complete abdominal retention.
As a result, they are tough to track down.
Part of the epididymus is found in the inguinal canal in partial abdominal retention, while the testicle itself stays in the abdominal cavity.
Most horses dislike being touched between their back legs unless they have received appropriate sedative.
The scrotum of a newborn foal might be difficult to palpate because it is so soft.
If just the epididymus is present in the scrotum, it might easily be misidentified as a testicle due to its size and shape.
To determine whether or not testicular tissue is present in the abdomen, blood tests might be performed in certain situations.
A single blood sample may be collected from horses three years and older to test for the presence of a hormone known as oestrone sulphate.
Cryptorchids have levels that are four to five times greater than those of geldings.
Obtaining a greater amount of HCG in a second blood sample (taken 60 minutes after the delivery of HCG) demonstrates the existence of testicular tissue compared to the first blood sample given before the injection.
Because the problem is hereditary, the only situation in which a cryptorchid should not be castrated is when it is thought that the patient is suffering from transient inguinal retention.
If it has not emerged in the scrotum by the time the horse reaches the age of three, it should be considered a case of permanent retention and castrated as a result.
Unless the horse is completely calm and lying down on its back, it is usually impossible to determine where the retained testicle is located in the body. The veterinarian will be able to detect the location of the inguinal canal after performing a thorough dissection over it.
Rigging up a rig op
Peter Gillespie, BVSc, MACVS, is a veterinarian who practices in the United Kingdom. A cryptorchid horse, or rig, as it is more often known, is a horse that has one or both of its testicles retained in its inguinal canal or abdominal cavity throughout development (Fig 1). Most of the time, the issue stays unnoticed until the horse is castrated, at which point it becomes critical. The testicles are positioned in the abdominal cavity, behind the kidneys, during the early stages of foetal development.
- Retention can occur at any point along the path of the descending sphere.
- Among the two types of retention, inguinal retention is by far the most prevalent.
- When a retained testicle is positioned in the inguinal canal, this is referred to as inguinal retention.
- Small testicles weighing less than forty grams are the hallmark of temporary retention, which affects mostly ponies.
- The retained testicle can occasionally be felt in the inguinal canal, but more often than not, the horse must be sedated in order to obtain confirmation of the testicle’s placement.
- When a horse’s testicles weigh more than forty grams, he is said to have permanent inguinal retention, which can affect any breed.
- The right and left sides of the testicles are both damaged equally in this disorder, which occurs most commonly in one testicle.
When the testicle remains in the abdominal cavity, it is referred to as abdominal retention.
When both the testicle and the epididymus are maintained within the abdomen, this is referred to as “complete abdominal retention.” In most cases, these testicles are fairly little since they have not been able to properly mature as a result of the effects of elevated abdominal temperatures.
The coils of intestine might become entangled with them because they are rather mobile in the belly.
A cryptorchid’s diagnosis is the responsibility of your veterinarian.
Especially under the impact of anxiety, chilly weather, or icy hands, they are capable of retracting their testicles upwards in rapid succession, making the determination of the kind of retention difficult.
A testicle can grow to be bigger than the epididymus at this age because the tail of the epididymus is longer.
In situations when both testicles are retained in the abdomen, it might be difficult to determine whether the horse is a cryptorchid or a gelding, especially if the horse’s history is unclear at the time of diagnosis.
Two tests are available; whether one is utilized will depend on the patient’s age.
Grooming levels are four to five times greater in cryptorchids than in geldings.
Testicular tissue can be confirmed if the amount of HCG in a second blood sample (taken 60 minutes after delivery of HCG) is higher than the level in the first blood sample collected before the injection.
Because the disease is hereditary, the only time a cryptorchid should not be castrated is if it is thought to be a case of transient inguinal retention, which is a rare occurrence in this setting.
If it has not emerged in the scrotum by the time the horse reaches the age of three, it should be viewed as a case of permanent retention and castrated as a result of this.
Unless the horse is completely calm and resting on its back, it is usually impossible to determine the location of the retained testicle. The veterinarian will be able to pinpoint its position after performing a thorough dissection over the inguinal canal.
Behaviour of the false rig: causes and treatments
The fake rig is a castrated horse that exhibits some form of macho behavior in one form or another, depending on the situation. The author discusses the behavior patterns described to him by owners of such animals, as well as the likely reasons of these behaviors. Some of these horses may exhibit all of the behaviors associated with the entire species, including erection and intromission. Evidence is offered to demonstrate that the behavior is neither driven by hormones or dependent on hormones.

Could I tell if he’s a rig without a vet?
To determine whether a horse is a rig, your veterinarian would need to do a blood test to check for elevated amounts of testosterone. If excessive amounts of testosterone are observed in a horse, this does not always imply that the horse is a rigged horse. In addition to testicles, testosterone can be generated by other tissues, such as some types of tumors or the dermis. The testosterone is produced by the tube that used to lead to the testicle. If too much of this is left behind after the horse has been gelded, the horse may exhibit rig-like behavior, and a testosterone level higher than that of a gelding horse may be detected in the horse’s blood.
Gipsies frequently utilize this method because they want horses with a lot of movement and personality (the Gypsies I know are not fond of geldings since they are dull).
It might take up to a year after a horse has been gelded for the testosterone levels to return to normal.
gelding a horse too late is that the horse will have gotten used to stallion-like behavior.
What to do with a rig?
I understand how you feel because I had a small gray part for a year. He was a gelding, and he mounted everything, behaved worse than a stallion, and was a complete terror. I couldn’t see allowing a youngster to ride him in case another horse or pony got into touch with him. Despite the fact that the former owner said he had previously been tested, I chose to get him looked out. When the findings came back, it was discovered that he still had a testicle inside him and had not been cut wrongly in the first place.
- He was particularly terrible because of this, but I’ve heard that rigs are frequently worse than stallions.
- Alternatively, if he has no testicles remaining inside him, you may get a supplement from worldwide herbs that may assist to calm him down.
- Also, I have a horse that is incredibly head shy and who has had a rough background, and it has taken me a year to finally persuade him to accept a bridle, and not in the conventional sense.
- To put it on, he has to wear it like a head collar, with the bit on last.
The point I’m trying to make is that given enough time, you will find ways to overcome his problems. Don’t get me wrong, I’ve been this close to giving up on him, but three years later, we have a wonderful relationship. My fingers are crossed that you will find a way.
Vintage horse rig, chic and functional?
Around 1914, my father is shown in the attached photograph cultivating a field of corn on the family farm near Rokeby, Nebraska. What is the function of the ropes that dangle down the flanks of horses? A:Fly cords, similar to fly sheets, are employed as fly protection or deterrents in the same way that they are used today. Because flies enjoy the hot, slightly humid environment of the cornfields, when the crew pulled through the fields, all of the flies were agitated and spread over the area.

Cryptorchidism (Undescended Testicles) in Horses
Terms that are associated with it: Undescended Testicle, Retained Testicle, Rib Ridgling, Proud Cut, High Flanker, Undescended Testicle, Undescended Testicle The term “ACVS Diplomate” refers to a veterinarian who has received board certification in veterinary surgery from the American College of Veterinary Surgery. Only veterinarians who have successfully completed the certification requirements of the American College of Veterinary Surgeons (ACVS) are entitled to use the title “specialist in veterinary surgery.” Diplomates of the American College of Veterinary Surgeons (DACVS) are the only ones who have earned the right to use the title “specialist in veterinary surgery.” Your board-certified veterinary surgeon from the American College of Veterinary Surgeons (ACVS) completed a three-year residency program, met specified training and caseload criteria, conducted research, and had that study published.
- This procedure was overseen by ACVS Diplomates, who ensured that the training was consistent and that the high standards were adhered to.
- It was only after that that your veterinary surgeon was awarded the ACVS Diplomate designation.
- This word refers to a condition in which one (unilateral) or both (bilateral) testicles do not descend normally into the scrotum, as opposed to the typical descent.
- The retained testicle can be found everywhere in the body, from the abdomen to the inguinal canal, which is the typical path by which the testicle passes into the scrotum (Figure 1).
Several variables, including genetic, hormonal, and mechanical, are thought to be involved in the development of the illness.” It is roughly equal in prevalence between left and right testicular retention, albeit retained left testes are more frequently seen in the belly, whilst a retained right testicle is more frequently found within the inguinal canal.
Considering that the issue is heritable, afflicted dogs should be gelded to assist prevent the progression of this congenital problem and to ensure their safety and behavioral stability (although a testicle is undescended, it still produces male hormones leading to characteristic stallion behavior).
Cryptorchids are also prohibited from being registered with several breed groups. Symptoms and signs include: Cryptorchid horses are distinguished by the absence of one or both scrotal testicles, which can be seen or felt on the horse’s hindquarters.
- Immature horses may go undiagnosed until they are inspected immediately before they are castrated as part of a standard castration procedure. The following conditions may be present in mature horses with no identifiable testes that behave like stallions:
- Unilateral cryptorchid with the descended testes removed
- Bilateral cryptorchid with the descended testes removed
- Geldings with stallion-like behavior (castrated later in life +/- prior breeding stallion)
- Geldings with stallion-like behavior (castrated later in life +/- previous breeding stallion)
Among horses, monorchidism (the entire absence of one testicle) is extremely unusual and should only be addressed after comprehensive testing and potentially invasive surgical exploration. Diagnostics: Your primary care veterinarian may recommend that you have the following diagnostic procedures performed:
- Testicle location is accomplished using a combination of external and rectal probing, as well as ultrasound testing, in the abdomen or inguinal canal. Performing blood tests to measure testosterone and conjugated estrogens when there is an incomplete surgical history or when there are no externally palpable testicles is recommended (about 95 percent accurate
- If one test is unclear, the other should be performed).
- HCG (human chorionic gonadotropin) levels were measured in the blood before and after delivery of the hormone (hCG).
- Stallions and cryptorchids have greater testosterone levels than other animals, and their levels of the hormone rise after being given hCG treatment. Castrated horses have low testosterone levels, which do not increase as a result of the injection of hCG.
A single measurement of conjugated estrogen levels may generally distinguish cryptorchids from other horses with testicular tissue since the levels are often greater in these animals.
- A single measurement of conjugated estrogen levels may commonly distinguish cryptorchids from other horses with testicular tissue since the levels are often greater in these animals.
Treatment:The detection and surgical excision of undescended testicles should be performed by an ACVS board-certified veterinary surgeon. In this location, the anatomy is quite complicated, and testicles are frequently smaller than usual in size and shape, and they may have an aberrant look due to their atypical formation / shape. When trained according to the criteria of the American College of Veterinary Surgeons, veterinary surgeons are equipped with particular knowledge and abilities for diagnosing and treating cryptorchidism in horses.
- Surgery is performed using a standard approach: with the horse on its back and under general anesthesia, an incision is made around the external inguinal ring of the horse’s pelvis. After being properly found, the testicular tissue is physically removed in its entirety from either the abdomen or the inguinal canal. On a normal basis, it is possible to seal the external inguinal and close the incision. The belly is distended with sterile carbon dioxide gas and a camera is placed into the abdomen by a tiny incision in the flank (if the horse is standing) or umbilicus (if the horse is lying down) using a camera and specialist equipment (on their back under general anesthesia). Once the testicle has been found, more tiny incisions are made to allow equipment to be sent into the abdomen and the testicle to be removed.
In any case, painstaking care is taken to ensure that all testicular tissue is removed and that the blood supply to the testicle is safely blocked off prior to removal in order to prevent possible bleeding during the procedure. Aftercare and a positive outcome: Depending on whatever surgical procedure was performed (open vs. laparoscopic), your ACVS board-certified surgeon will provide you with detailed postoperative care instructions, which include specific discharge instructions. When using the open technique, stall rest with hand walking is commonly used for a short amount of time, followed by a progressive increase in exercise after roughly 10 days to two weeks.
Laparoscopic surgery has a far shorter recovery period than traditional surgery, and horses can return to turnout and mild exercise after only 72 hours, with exterior suture removal taking around 10–14 days.
As is the case with any surgical operation, there is always the possibility of complications, which might include:
- When you are under general anesthesia, you may experience complications. Inadvertent injury to the gastrointestinal tract due to excessive or uncontrolled bleeding Infection of the surgical site
- Swelling that occurs after surgery
- Failure of the incisional site, which is frequently caused by infection and edema
Despite the fact that hormone levels drop nearly immediately after testicle removal, learned stallion habits frequently require time and training to modify and can last for an endless amount of time depending on the individual horse.
