Googling is getting me nowhere with this question, so I hope someone here can help me!
So I started wondering about the origins of using “xx” and the others in some horses names. When did this start and what was the idea behind it? Is it only a way to spot the arabians and thoroughbreds in pedigrees? Sometimes I see these used in horse names too, not just in pedigrees so what’s up with this?
Any info would be appreciated!
X is used to indicate an outcross of non registered stock in registries that are/were open book
I was taught xx is full TB, x is Anglo, and xo is Arabian. You see these a lot in the TRAK registry.
I have seen xx a lot (TB and WB lover here). Puzzled is right… although it is ox not xo for Arabian. Here is some reading material on it, may give you more on why this is done and some other pedigree tid bits:
xx is TB, x is Anglo Arab, ox is Arab when looking at warmblood/sport horse pedigrees. (If you’re looking at a TB pedigree, for example, since everything is a full TB, you will not see any designated as such with the xx.)
I know what xx, x and ox mean, that was not my question. To quote my first post: “When did this start and what was the idea behind it? Is it only a way to spot the arabians and thoroughbreds in pedigrees? Sometimes I see these used in horse names too, not just in pedigrees so what’s up with this?”
rockonxox, thank you for the link. The text makes it seem that xx and others are indeed used to spot these breeds in the pedigree just by looking that name.
I don’t think the xx for example is used as part of the horses registered name. Some show programs list breeding of the horses showing and will put xx, x, etc after the sire or dam if it applies
