Suggested Feeding Rates

If feeding RacePower for the first time gradually introduce over a minimum 14 days so the horses digestive system can adjust gradually to the new diet. When in moderate/heavy work split daily total between a minimum 3 feeds per day. Provide additional good quality fiber and give open access to fresh clean drinking water and salt block if needed. Selenium testing is advisable to ensure levels meet the horses individual needs.

Should i feed RacePower for racing horse prone to tye-up?

NO. 
Many horses prone to tying up (like those with PSSM) cannot handle the high soluble starch from oats or extruded feeds. We suggest MegaBoost to avoid excessive starch uptake and reduce the risk of over-storing glycogen in sensitive horses.
Harvest Grains Vitalize is effective and provides good results when fed as part of the daily diet of horses needing a lower grain diet. Contact us for more information.

Is RacePower compliant with FEI rules and NZ Rules of Racing

✅️YES. RacePower does not contain any prohibited/illegal substance listed under FEI rules or NZ Rules of Racing.
NB : not a treatment for discomfort or disease - call your vet if animal is unwell.

When and Why to supplement with Electrolyes or Salt

🆘 For racehorses or high-performance horses, it is necessary to use electrolytes daily during peak training and add extra doses post-workout, especially in warm weather or after transport.

1️⃣ Hot/humid weather ✅ Yes.  Horses lose more fluids and electrolytes through sweat.

2️⃣ Intense or prolonged exercise ✅ Yes.  Especially important after gallops, races, or long travel.

3️⃣ Travel stress ✅ Yes.  Travel can increase fluid loss, reduce water intake.

4️⃣ Sweating heavily or visibly ✅ Yes.  Replace sodium, potassium, chloride, magnesium lost in sweat.

5️⃣ Post-race or hard training ✅ Yes.   Aids muscle recovery, hydration, and faster bounce-back.

6️⃣ Cold weather, low water intake ✅ Maybe.  Electrolytes can help encourage drinking if dehydration risk is high.

7️⃣ Rest days, minimal work, no sweat ❌ Not necessary.  Avoid excessive supplementation when not sweating.

Does my horse require extra minerals or selenium

Selenium levels in hay, pasture and water vary widely throughout New Zealand.
Testing is advised.

➡️ High-performance horses have elevated demands for:

  • Electrolytes (sodium, chloride, potassium, magnesium)

  • Macro minerals (calcium, phosphorus)

  • Trace minerals (zinc, copper, selenium, manganese, iodine, cobalt, chromium)


➡️ These minerals are essential for:

  • Muscle function and recovery

  • Bone strength and integrity

  • Red blood cell formation

  • Immune function and antioxidant defense

  • Energy metabolism and nerve transmission

⚠️ Gallops, sweating, travel and stress will deplete these nutrients faster than when horses are in steady training. 

  • ✔️ RacePower is not high in selenium. This allows safe use of additional premium quality purposeful supplements to be given.

  • Use a professional-grade mineral/vitamin balancer when required:

    • Feeding less than the recommended rate of commercial feed

    • When work-load and sweat loss increase

    • When using additional grains or unfortified mixes

    • Needing to fine-tune recovery, metabolism, or hoof/coat condition

  • Choose organic or chelated forms (e.g., selenium yeast, zinc methionine) for better absorption..

💡Feeding Tips

  • If feeding below the high rate, top up with a balanced vitamin & mineral supplement to avoid nutrient shortfalls.

  • Always provide access to clean water and quality forage.

  • Add sodium chloride (salt) or electrolytes to compensate for sweat loss in hard-working horses.

  • Seek professional guidance to ensure optimal selenium levels.
