Breeding Balancers

Supporting Optimal Nutrition for Breeding & Pregnant Mares

Providing the best start for a foal begins with the health of the mare—even before conception.

A well-balanced diet, aligned with the forage-focused™ approach, ensures essential vitamins and minerals are available throughout pregnancy and lactation, supporting both the mare and her developing foal.

At Forageplus, our breeding mare horse feed balancers are scientifically formulated to match the natural diet of horses, delivering the precise nutrition needed to promote strong foetal development, optimal milk quality, and overall reproductive health.

What Feed Does a Breeding Mare Need?

Throughout pregnancy and lactation, a mare’s nutritional needs change significantly:

Early Pregnancy (First Two Trimesters)

✔️ Feed a high-quality balancer with key minerals and vitamins—our Hoof & Skin Health Balancer supports foundational nutrition.
✔️ Begin supplementation at least 6 months before conception to build mineral reserves essential for foetal development.
✔️ For mares with limited access to spring or summer grazing, add micronised linseed to provide adequate omega-3 fatty acids.

It is only in the last trimester that things need to change and cater for the increased growth of the foetus.

Last Trimester – Preparing for Foaling

Ideally, as you approach the last trimester you need to carry out a forage analysis test of the grass or hay the mare will be eating.

This means accurate feeding requirements can be determined and a breeding horse feed balancer matched to forage so that both the mare and foal can be provided with optimal nutrition throughout the pregnancy and beyond.

Deficiencies of certain nutrients and excesses of others mean that foal health can be compromised not just in the short term but into adulthood too so really knowing what is contained in the pregnant mare’s diet is crucial.

✔️ Forage Testing – Where possible, test the grass or hay to identify deficiencies and tailor supplementation.
✔️ Balanced Nutrition – If forage testing isn’t possible, we recommend feeding:

• Working Young Horse Winter Balancer (400-600kg mare: 250g/day)
• Additional essentials:
  • 10g salt (table, sea, or rock salt)
  • 2 x 15ml scoops Magnesium Oxide
  • 1 x 10ml scoop L-Lysine
    ✔ Protein Boost – Protein demands rise significantly; consider adding 50-100g whey, pea protein, or Topline Plus daily.

By the time many pregnant horses get to the last trimester, they may be on spring grazing. So, as long as the mare has more than 6 hours of good grazing, then feed the Working Young Horse Summer version with the above additions included as well.

Lactating Mares – Supporting Milk Production

Continue with the above recommended balancer and additional nutrients if forage testing isn’t available.

If feeding on older, less nutritious hay, supplement with:

• 30,000 IU Vitamin A per day (available in human-grade soft gel capsules).
• Vitamin E-rich winter balancer for antioxidant support.
• Micronised Linseed (42g per 220kg body weight) to maintain omega-3 balance.
