'How do you select a breed worthy colt? The potential show and breeding stallion'
As others have said, I don't think the two go necessarily hand-in-hand. In showing, a horse might do extremely well under some judges, but not others. It is purely how the judge interprets how he/she thinks the breed should look and the horse on a given day.
But lets face it, most of the time we would purchase a colt for future possible breeding. While many on all-breed forums, darn those who breed for colour, I think there is nothing wrong with it. If one has a herd of mostly solid mares and wants colour, of course we would look for a stallion/colt of colour. Hopefully he might be homozygous. Some might want frame, others might not and prefer a homozygous tobiano. Some might wish to add silver or the many other colours found in the breed. Nothing wrong with breeding for colour, if everything else is in place. Of course, seeking a colt of a particular colour, will limit the the buyer somewhat. That said, in Minis, there are superb examples of the breed in every colour.
After that I think, one has to consider what one is breeding for. Do we want a very modern Araby type or a colt with more substance and bone? This lessens the possibilities even further. We must also decide what faults we abhor in the breed. If a possible purchase has everything we like, but has that thing we detest most, then we keep on looking. For me personally, it's straight rears and low tail sets, which we see so often. I want angulation. Targetsmom's Max, is the kind of colt I'd want to see. Super angulation, short back, wonderful shoulder, correct tail set, correct neck set and a pretty head. If we find such a colt who might not be for sale, we could wait and breed to him later, if the owner agrees. If not, we look to his sire and dam and wait for the next one. If none were to be available in the future, then we might consider looking into that line/pedigree, to see others out there.
I like pedigrees! I like to (hopefully) be able to see horses in the background of a colt I was considering. Is the colt linebred or inbred? If so, on what horse? What did he look like? What has he produced? If a colt is linebred/inbred on a horse I particularly like, then I'm more interested. He has the propensity to produce horses much like the horse which appears several times in his pedigree. Anything past the 4th generation, won't mean much. It's certainly those first three and maybe fourth generations, which mean the most. This is where one's knowledge of pedigrees and the horses therein, become important. And lets not forget the mares, in those up-front pedigrees. They mean as much and maybe even more, than the sire of the colt we are considering. I think I wrote this elsewhere, but will post it here if not....
For generations, breeders of all kinds of animals, have often relied upon the knowledge of the male, when considering breeding. ie. His quality, get, pedigree etc. Many in the past, bred mares of poor or iffy quality, to superior stallions, with the thought that he was bound to produce always, quality offspring. Modern thinking and knowledge however, has told us that the mare used, is just as important as the sire. In some ways, even much more important.
Genetisists tell us that the fact is, that certain qualities inherited from DNA on the x-chromosome can ONLY be inherited from a mare. So down the line, the maternal granddam, grandsire and their quality, cannot and should not, be ignored.
We all know, that very horse has 2 chromosomes that determine gender.
A mare has two X-chromosomes, therefore a female.
A stallion (XY) has one X-chromosome and one Y-chromosome, therefore a male. When a foal is conceived, if the Y-chromosome fertilizes the egg, the foal will be male (XY) because it will then have an "X" from the dam and a "Y" from the sire.
If the sperm fertilizing the egg carries the stallion's X-chromosome, the resulting foal will be female - XX.
A mare, contributes one of her two X-chromosomes to her foals, both male and female but when a stallion gives an "X" to his daughters, it is the X-chromosome he inherited from his own dam.
His sons NEVER receive his X-chromosome, because he has given them (obviously) his Y-chromosome instead. However, his sons DO receive an X-chromosome - one of the X-chromosomes contributed by their dam.
And this gets even more interesting. One of those would have been inherited via the dam's dam, and the other came down the "X-trail" from her sire's dam.
Geneticists have determined that certain genetic material is carried on the X-chromosome, including that for the large heart, and intelligence. Most probably, there are many other genes passed down on the X-chromosome, many of which we probably don't even know about at the moment.
So now, understanding that certain superior qualities can ONLY be inherited from a mare, her expressed qualities and that of the maternal granddam and grandsire suddenly become incredibly import.
Anyway, just a few personal thoughts on how one might decide upon purchasing a colt.
