I'm looking to get into racing and am in the beginning stages now. (The information and learning stage...)
This mare is a blend of polish and Egyptian blood and while I know her conformation isn't very good, I was wondering if she looks like she has what it takes to produce a racehorse. Her registered name is Las Whites Dina, if you want to look up her pedigree, and she's 15 years old. If she were bred to a good quality-racing stallion, would the foal be worth the effort of training? What are your thoughts in general on this mare? (Please note, the second picture was taken before her feet were trimmed...they have been taken care of since this photo was taken.)

Where is your photo? you are talking about?

Hello,
She seems to be a really nice mare.
My friend and I just did a placement rescue on a herd of racing Arabians, Pure polish.
They seem to have the same hump on their backs.

You should e-mail my friend Melissa. She is really good on judging conformation on horses.
If she is weak in some areas, she can tell you how to make her better.

I couldn't tell you. She's not broke to ride. She doesn't seem slow, but that's just running in the pasture. When the hubby was herding them with he 4 wheeler, she sure did scoot...

If you are looking to produce a quality race horse, dont start out with something that needs help to be better conformationally. I dont mean to be harsh but I have been breeding for years(specifically barrel racing QH) and been a horseman all my life and I can tell you if you want something other than mediocre invest your money in a good colt from a reputible breeder.
If you have an OK mare conformationally and you spend top dollars to breed her to a Good proven stallion, you may very well be wasting your money. If your mare is not up to par conformationally( I cant see any pics so i am just going off your post) than alot of top breeders wont even allow it to begin with. If they do and you get a so so colt no reputible trainer is going to take it on as it has less chance of making it on the track.
So, I would suggest finding a top level racing farm and buying a prospect, it will be from proven stock, good conformation, easy to find a trainer who is willing to train it(racing) and will more than likely end up costing about the same when you ad up the vet bills, stud fee, feeding, wait time, etc...as breeding for one that will be potentially less valuable in the end.

Set aside from conformation is also comes into play any racing pedigree on the mare's side. I tried to look up her pedigree, but it never displayed for me. Aside from the fact that she never ran herself nor (I'm asuming) has any of her past family. The better racing pedigree you can get on the dam's side of the family tree is the strongest. If you want to get into racing, I would start with buying a horse that is already raced trained. That way you can get a feel for the sport and will not have to as much money on the preperation to get to the race.

With Arabians, they are not allowed to race until the age of 3. So, you have 2.5 years of letting the foal be a foal, then you have about 2-3months of breaking, then you have another 2-3 months of race training in hopes of the horse making it to a race. You have to consider ones with not enough speed, and/or injuries. Many end up racing training, but never make it to the race. Like Saben said, you have vet, farrier, trainer fees. The trainer fees alone are around $35-45 a day, farrier $120 every four weeks (racing plates are not cheap), and the vet.

If you are looking to make any kind of money you might want to consider a TB. There are very few tracks that race Arabians and the purses arn't all that great!

I agree with sabenquarterhorses its not a good idea to try and breed a so so on conf. horse and expect a really great baby no matter what the sire is. sorry so harsh.
