Can someone please give me information on what exactly a roarer is?

Roaring is also referred to as Laryngeal Hemiplegia. It is the damage or disease of a nerve called the recurrent laryngeal nerve that supplies the muscles that control movement of the arytenoid cartilages when the horse breathes. This results in the partial or complete paralysis of one of the arytenoid catrilages, leading to an obstruction of the airflow when the horse takes a breath. It usually effects effects the left side. The exact cause of this condition is unknown, although larger horses appear to be more at risk.

Treatment is often unnecessary. Even with complete paralysis of one aryteniod cartilage, horse continue to preform in many disciplines without compromise. However, it may interfere with high intensity sports due to the limits of oxygen intake.

The noise can be extremely distracting and becomes more pronounced in disciplines such as dressage where neck flexion is required.

Surgery for roaring involves placement of large structures to hold the cartilage open (called a tie back). Sometimes this can be combined with a secondary procedure called a ventriculectomy which involves removing the small sac that sits next to the cartilage which scars down and helps hold the cartilage out of the way.

In severe cases removal oft the affected cartilage may be recommended.

Roaring can be caused by a few things, most commonly nerve paralysis and obstruction. A horses' laryngeal nerve, the one that opens and closes it's larynx is extremely long- it actually loops around one of the branches of the heart when the foal is developing in the womb, and as the fetus grows, the heart and brain get farther and farther apart, resulting in a nerve that is twice as long as the adult horses neck. In horses, this nerve is soooo long that sometimes it has trouble carrying the message to "OPEN LARYNX" all the way across it. The result is a horse that can't breathe properly because it's windpipe is partially blocked by the pharynx.

I've personally known one horse that was a roarer. He was retired racing TB and needed surgery to correct his breathing when he was about 8 years old. As far as I know, there is no other treatment for it, excepting if the roaring is caused by inflammation or an obstruction that can be removed. This horse went on to do dressage after surgery, but still had a slight wheeze at anything faster/more strenuous than a canter. Obviously some horses do "cope" with it, as this horse was 8 before his owner fixed it, but horses are incredibly stoic and if it's something the horse has dealt with for most of it's life, he probably wont tell how much it hinders him. As you can imagine, roaring really affects how much activity a horse can do. You might as well put a plug in one nostril and a straw in the other and expect a horse to work with that much oxygen. My advice would be that unless you plan on fairly expensive surgery, and his price reflects that cost, not to buy this horse. There are plenty of healthy, talented horses out there today, at bargin prices due to the economy.

Good luck!

ill give my advice dont ever buy a roarer there is no such point in it!!!

grade three is the worst a horse can get

a horse has two flaps the over lap each other in the throat which helps direct food and air down into the right parts of the body with hard work and excersize it causes the flap to overlap the wrong way which in turn causes the roaring sound as the flap not where it should be most horses will cough as it feels uncomfortable and some if they have had it for a while will put up with this!!! sometimes its causes by a bad infection the horse may have had and sometimes its to do with breeding having an unaturally small trachea which enables it to overlap the wrong way......

dont buy i can assure you its not a good choice at all!!!

buy something fit and healthy as this horse will be very hard to keep in top physical peak due to his condition.....

there is evasive surgery that can be done but it may not work or be the same and there will be strict limits to work and excersize for many months .....

i would look for another suitible horse

IP's can be traced to your ISP (Cox, AOL, etc.) and your city (or at least the city where your ISP is located.) This can be done by entering the IP into numerous free on line services that do this. There are ways (part of sending cookies to a computer ) that can give the sender the type of computer (Mac, Windows, etc.) and what browser, etc. These can be defeated by only accepting cookies from the actual site visited, unless they are coming from the site. (Another reason to KNOW the sites you are visiting. A legitimate site will NOT want this type of info. BTW: Windows does this for MS, so that MS can determine "user preferences". A total invasion of a purchaser of Windows' privacy.) There are also some virii that "phone home". That means they send all of your info to the location specified by the virus sender. A good anti-virus, anti-phishing software program will stop this. The last way is for someone to actually hack into your network and then into your computer. Very rare and difficult if everything is properly protected and firewalls are in place. (It is much more fun and rewarding to hack into a major site rather than some common Joe Shmoe.) Beyond that requires very specialized software that is legally only available to law enforcement and the like.

RE:

I am thinking about purchasing a gorgeous talented horse that has been scoped and diagnosed as a grade three roarer. Can anyone tell me what this is and how it will affect the horse? Also anyone out there who has owned a roarer before can you tell me how you dealt with it, and what kind of vet...

Its a term that describes horses which make an abnormal respiratory noise during exercise. Its because they have something wrong in their respiratory tract, and their trachea narrows with exercise making it difficult for them to breath. The only real treatment is invasive surgery, and sometimes it gets worse and worse with age.

If you only plan to ride him lightly, and you really love him then perhaps you should buy him.. but if you want to compete and do high energy riding then perhaps he's not the one for you. Ask a vet! :)

Grade 4&5 are considered to be servere for racing.

just ask them. I can't find it on google anywhere. so, just ask the people you are thinking about purchasing from what it is.

EDIT

I just found it. That might not be good for the horse your looking at:

EDIT

you will have to do surgery if the horse has it bad. It is a respritory disease. not sure what grade 3 is,though.

From what I read a roarer has a problem with the larynx and will not be able to do much of anything but walk.
