Ylva,
Dobney et al (apologies to the other authors for not having their
names to hand!) in their paper in the international journal of
osteoarchaeology in 2001 determined that it's unlikely to be
caused by use of yokes on cattle as the condition was found in a
prehistoric wild individual. I'm inclined to agree and think it's more
likely to be a non-metric trait. I was just interested if it's a non-
metric trait associated with the animal having horns.
