I want to know, how this would impact selection for which mares get accepted into the stallion’s book – stud managers would have to be much more discerning about who is paired, I assume…
Which then means as everyone pointed out, it’ll bump a lot of mares down to a lower tier stallion, wouldn’t it?
Which is not always a good thing, IMHO.
We’ve gotten some good horses from some “wait, really?” pairings… Does anyone think this is a potential issue?
What about the incentive to have the stallion stand in a different hemisphere vs just shuttling for the season? I’m not a breeder, but I imagine if I had a stallion in demand that had a mandatory breeding limit, that I might consider that stallion traveling/shuttling versus staying at home…
I’m not really worried about genetic diversity now, the TB has never been particularly diverse, and the same goes for most breeds of domesticated horses – but I imagine limiting the studbook of top stallions (or any stallion) would then limit the diversity of the mares sent to that stallion, which then would impact the diversity years down the line. Especially if “top level/best tier” mares are consistently paired with “best tier” stallions, over and over (which I imagine would be the case in the matter of a limit).
