Optimising Mineral Supplementation In Racehorses: Achieving Excellence Through Strategic Nutrition
The Science Of Precision Mineral Management
Achieving optimal mineral balance in racehorses represents one of the most sophisticated challenges facing modern equine nutritionists, where precise supplementation programmes determine the difference between elite performance and career-limiting deficiencies. Contemporary racehorse management demands an increasingly scientific understanding of mineral requirements, extending far beyond basic nutritional guidelines as horses face extreme environmental conditions and intensive training regimens.
Successful mineral supplementation recognises minerals function as interconnected systems rather than isolated nutrients. Dr Sujeet Bhaskar Suryawanshi, a veteran Equine Veterinary Surgeon with over 20 years of experience at Sharjah Equestrian and Racing Club and overall 28 years of experience over the globe in the industry, exemplifies this advanced approach: "My first priority other than the essentials is the gut. I focus also on micro minerals and trace minerals. Of course, they are important, but the horse's whole feeding and gut absorption capacity are more important."
Dr Suryawanshi's distinguished career spans multiple continents, beginning with post-graduation from the Indian Veterinary Research Institute and early training in the Indian Thoroughbred Industry, Saudi Arabia & Ireland, "The house of Thoroughbreds."
His journey to the UAE started over 20 years ago at Sharjah Equestrian and Racing Club, which has evolved from ‘hardly 200 boxes’ to become ‘the biggest facility in the whole Middle East’ with ‘more than 1,000 permanent and air-conditioned boxes.’ The club represents "the oldest organised equine activity in the country," maintaining its traditional importance whilst embracing cutting-edge veterinary technologies.
Understanding Essential Mineral Requirements
Calcium and phosphorus form the cornerstone of equine skeletal health, comprising approximately 70% of the mineral content in a horse's body. Maintaining the optimal calcium-to-phosphorus ratio of 1.5:1 to 2:1 for racehorses is critical for bone development and maintenance. Research indicates that racehorses require calcium levels 15-20% above basic maintenance requirements due to the intense bone renovation during training.
The importance of this is becoming particularly acute in young racehorses beginning training. "Young horses, of course, are different because of how they grow - they still have scope for growth & development. We start breaking them at two and a half years of age, when the bone is still green, and not mature enough," Dr Suryawanshi explains. This developmental challenge means "the training challenges bring them essential mineral requirements for bones and the whole skeletal system," he notes.
Electrolyte management represents one of the most dynamic aspects of mineral supplementation in racehorses. Under normal training conditions, horses require approximately 1.6-1.8 grams of salt per kilogram of feed dry matter. However, intensive exercise dramatically increases these requirements, with horses capable of losing over 30 grams of salt in just 1-2 hours of hard work.
Copper and zinc are critical partners in racehorse nutrition, competing for the same absorption pathways and requiring careful ratio management. The optimal zinc-to-copper ratio of 4:1 ensures proper absorption of both minerals while supporting their diverse physiological functions. Daily requirements for a 500kg racehorse include 100-125mg of copper and 400-500mg of zinc. These requirements increase significantly during intense training due to substantial sweat losses—up to 21 mg/l of zinc and 4 mg/l of copper.
Selenium works synergistically with vitamin E to provide powerful antioxidant protection, which is particularly important for horses under intense exercise stress. However, selenium supplementation requires exceptional precision due to its narrow safety margin. The optimal supplementation level of 0.1mg/kg of feed dry matter must be carefully monitored to avoid toxicity and ensure adequate antioxidant protection.
Iron requirements vary dramatically based on exercise intensity, ranging from 500mg/day for light work to 1200mg/day for heavy exercise. Manganese supports bone formation and energy metabolism, with requirements ranging from 350mg/day for light work to 500mg/day for intense exercise.
Implementing Advanced Management Strategies
Modern approaches to mineral supplementation recognise that absorption capacity determines effectiveness more than absolute quantities provided. This philosophy emphasises that providing minerals is meaningless without optimal digestive function. "I've been very successful with and gotten beautiful results from herbal supplements, which are purely organic, prebiotics, and probiotics," Dr Suryawanshi notes.
This approach integrates biological supplements to optimise digestive function before addressing specific mineral deficiencies. "The gut has become a vast area of focus. The good factor goes to the horse, and everything shows in its behaviour," Dr Suryawanshi observes. Maintaining optimal gut health is critical under environmental stress, where extreme conditions compromise digestive function and mineral absorption.
Effective mineral management requires comprehensive monitoring beyond traditional visual assessments. "The best thing I do is regularly check their haematology and blood biochemistry at set intervals, which is very common for us with fresh blood samples. It's the number one priority," Dr Suryawanshi emphasises.
Advanced diagnostic approaches now include DEXA scans for bone density assessment, (support of MRI & CT Scans), enabling precise adjustment of supplementation protocols. "Now, having more than a year of DEXA scans on bone density and body composition, we base our decisions on scientific data," he explains. This scientific approach enables targeted interventions based on measurable data rather than empirical observations.
Managing Environmental Challenges
Extreme environmental conditions create unique challenges for mineral management, requiring specialised protocols. The concept of thermal shock, where temperatures rapidly increase from comfortable conditions to extreme heat, creates physiological stress that dramatically alters mineral requirements.
"In the last two to three years, we've had temperatures that cross 50 degrees some days, and humidity that crosses 85%. That's where the real challenge lies," Dr Suryawanshi notes. This extreme environment necessitates completely different approaches. "Everything in horses is related to stress and temperature variations, and they show it on their body," he explains.
The challenge extends beyond daytime heat. "Even at night, the temperature is sometimes 40-42 degrees. It's very hot. It's 70-75% humidity at three o'clock," Dr Suryawanshi notes. These conditions require constant attention to mineral balance and hydration status.
Environmental factors significantly amplifies electrolyte losses, particularly in extreme climates. Advanced electrolyte management requires sophisticated approaches. "We go with specific channels for water uptake. There are good products available which we put in the feed, and for some horses that need to retain more moisture and water in their body, we add supplements to their water as well," Dr Suryawanshi explains.
Effective mineral management recognises seasonal variation requirements. "We have a completely different programme for them to maintain them in summer," Dr Suryawanshi explains. The off-season is crucial for targeted intervention. "Summer is the time when we work on these individual needs. It's a balancing act. We go horse by horse with customised approaches," he notes.
Maintaining muscle mass during reduced training periods is becoming particularly challenging. "For four to five months, two to three months, they won't be worked out that much, so you need an optimum ration including hay. Once horses cross 6-7-8 years of age, maintaining that muscle mass is a big challenge," Dr Suryawanshi observes.

Addressing Individual Horse Requirements
Different breeds demonstrate varying tolerance to environmental stress and mineral requirements. "Thoroughbreds definitely, because 99% of them are coming from abroad. A Thoroughbred is like a pampered child. You must give them that attention and care. They get most of the thermal shock during summer," Dr Suryawanshi explains.
In contrast, Arabian horses show greater environmental tolerance. "The Arabians are a little bit stronger and sturdier. The ration for them, the caretaking for them, is different," he notes.
Horses demonstrate exceptional sensitivity to changes in mineral supplementation. "Even if you want to change the hay, we will not do it abruptly. Even if you want to change the feed, we will not abruptly change it. The changes got to be gradually introduced," Dr Suryawanshi explains. This sensitivity extends to all care aspects, requiring careful transition protocols that maintain mineral balance while adapting to changing demands.
Effective mineral management requires recognition that behavioural changes (mood swings / bucking / kicking / early exhaustion / not concentrating properly / etc.) often precede clinical manifestations of mineral imbalances. "The first thing would be behavioural changes. They will show signs, and when it goes above a threshold, it shows on the horse's body / system," Dr Suryawanshi emphasises.
Early detection is proving critical. "The good thing is that many times the PRs involved (Trainers / Assistant Trainers / Riders / Handlers / grooms) would sense it before it manifests clinically, because any affection or infection going on would be manifested clinically only when it reaches above a threshold level," Dr Suryawanshi explains. This emphasises the importance of integrating observational data with scientific monitoring.
Establishing Monitoring And Integration Protocols
Advanced monitoring protocols require detailed individualised evaluation. "You do blood /urine / specific tests, you go with analysis. Which horse needs extra support? Maybe some horses need the optimum level of electrolytes, but some horses need more. Some need to retain more moisture and water because they urinate more or have more paste-like droppings," Dr Suryawanshi details.
The monitoring frequency reflects the dynamic nature of mineral requirements. "That weekly or bi-weekly monitoring is essential," Dr Suryawanshi emphasises.
Modern mineral supplementation programmes benefit from integration with advanced veterinary diagnostics and treatments. However, the foundation remains consistent, avoiding excessive chemical intervention while supporting natural processes. "I don't push them with more chemicals because it corrupts the liver, then the kidney, then other systems if you're giving them heavy doses very regularly," Dr Suryawanshi cautions.
Advancement in veterinary medicine allows sophisticated treatment integration. "It started with PRP (Platelet-Rich Plasma). It started with IRAP (Interleukin-1 Receptor Antagonist Protein). Now they have stem cells and bone marrow treatments," Dr Suryawanshi notes, highlighting how modern facilities support comprehensive care approaches that complement proper mineral supplementation.
The emphasis remains on supporting the horse's natural capacity for mineral utilisation through optimised absorption and carefully balanced supplementation protocols.
Optimal mineral supplementation in racehorses requires a sophisticated understanding of mineral interactions, environmental influences, and individual horse physiology. The evolution towards gut-health-focused, scientifically monitored, and individually customised approaches represents the future of equine mineral management.
Success depends on recognising that effective supplementation requires comprehensive management systems rather than simple nutrient provision. Integrating scientific monitoring, environmental adaptation, and individualised care provides the foundation for achieving optimal mineral balance in performance horses, ensuring that supplementation supports immediate performance needs and long-term health in elite equine athletes.
