There is no better opinion than an informed opinion, and the vet who has actually examined the mare has the most information upon which to base an opinion. Sometimes difficult decisions, i.e., euthanasia, need to be made when the quality of life of the horse has badly deteriorated. We know of no supplements that will resolve nerve damage. As far as the welfare of the foal goes, the foal can be switched to a completely pelleted creep feed, such as Equine JuniorĀ®, or a similar product, provided free choice, so that the foal can learn to consume more solid feed early, which will ease its early weaning transition.
