I wonder if some of the mares got one or two breeding stitches in and not a full blown caslicks? Or - you got lucky and got mares that didnt have it done
I think its barbaric to be very honest. Fine and dandy if they need it, or you are breeding them and they are tipped and in order to ensure the foal "sticks" it has to be done, but to wholesale do it to every mare whether they need it or not - insane in my eyes.
Perhaps we need to approach the (predominantly male) vets with gut and needle in hand and say "this wont hurt a bit. We are going to do this stitching up procedure on you "just because" and "just in case your anatomy changes in the next 5-10 years or so and you need it"
Uh uh ... just doesnt happen around here unless they DO need it ...
