Nursing Mare Nutrition Calculator

Did You Know

Nursing mares have elevated nutritional needs to support the growth of their foals and their own health during lactation. The stage of lactation significantly influences a mare’s dietary requirements. Our Nursing Mare Nutrition Calculator is designed to help horse owners formulate a balanced diet that meets the increased energy, protein, and micronutrient demands of lactating mares.


Welcome to the Animal Nutrition Calculator’s Nursing Mare Nutrition Calculator. This innovative tool assists horse owners in managing their nursing mare’s nutrition effectively. By considering the mare’s current weight and stage of lactation, the calculator provides a custom feeding plan to ensure both the mare and foal receive adequate nutrition.

Getting Started: What You’ll Need

Tips for Feeding Nursing Mares

  • Energy and Protein: Mares in early lactation may require up to 75% more energy and 40% more protein compared to their maintenance needs.
  • Quality Forage: Provide access to high-quality forage to support milk production and the mare’s body condition.
  • Balanced Micronutrients: Ensure the diet is fortified with essential vitamins and minerals to support foal development and mare health. As the foal grows and starts to eat solids, it will be time to consider the nutrition transition they will need, which you can learn more about on our Weanling Nutrition Calculator page.
  • Adequate Water: Lactating mares need abundant water to maintain milk production.
