These mares could potentially benefit from such intervention.
Thursday, March 07, 2013Your foal has finally arrived, and he and mom appear healthy and happy. But don't let your guard down just yet: The mare's continued health dictates her milk production and whether the foal will not only grow but also thrive during his first few months. Supporting her overall and nutritional health becomes especially crucial.
Wednesday, February 20, 2013Breeders spend a substantial amount of time contemplating the logistics of breeding, such as choosing the stallion and where and who will be performing the reproductive work. But once a mare is in foal, a number of things can derail the pregnancy if veterinarians and horse owners don't keep a close eye the mare's progress. Sometimes, simply knowin...
