To optimize the diet

  • Purina recommends analyzing your hay and balancing the ration accordingly.
  • Feed clean and dust free hay in sufficient amount daily. Feeding poor quality hay or feeding inadequate amounts could cause colic and other digestive upsets.
  • Offer source of salt (NaCl) daily as well as plenty of fresh and clean water at all times.
  • Make any feed change gradually over a 7 to 10 days period.
  • Daily ration should be divided into 2 and preferably 3 separate feedings or more.
  • Use a scale to weigh your feed so you know exactly how much your horse is being fed. Do not feed by volume.
  • Purina recommends providing a maximum of 0.5% of body weight of this feed at one time.
  • These recommendations are intended as a guide. They should be adjusted to variables of management, environment and individual needs. Consult your Purina Equine Consultant if necessary.
  • Follow sound management practices along with optimal preventive veterinary medicine.
