The mare may need additional vitamins and minerals in the last two to three months of gestation to support foal growth, along with energy to maintain body condition. The horse may need a protein, mineral and vitamin supplement, like Sentinel Care Equine Choice Topline 30. During the last two to three weeks before foaling, it’s recommended to switch to a feed designed for lactation and foaling, like Sentinel Safe Start or Sentinel XT Grow. (Kristyn Sturken)
