Young horse feeding tips spotlight steady growth over speed

A new sponsored article from The Horse is putting the spotlight back on a familiar but clinically important topic: how to feed young, growing horses without pushing them into nutritional imbalance. Published March 11, 2026, “10 Tips for Feeding Young, Growing Horses” frames the issue around weanlings through early training, stressing that the goal is not maximum growth, but steady, well-supported development. An Equus Magazine version of the piece appears to exist as well, though it is currently protected. (thehorse.com)

The timing makes sense. Young horse nutrition has been a recurring concern in equine practice because rapid skeletal development leaves little room for feeding mistakes. AAEP guidance notes that from birth to age two, a young horse can reach 90% or more of adult size, and that mare’s milk may no longer fully meet nutritional needs by 8 to 10 weeks of age. That transition period, from milk to forage and concentrate, is where feeding programs often become more consequential and more complicated. (aaep.org)

While the new Horse article is presented as a practical tip sheet, its core themes match longer-running evidence-based recommendations. The publication says young horses depend entirely on forage and concentrate after weaning, and that diets must balance protein, energy, vitamins, and minerals to support strong growth without oversupplying nutrients that could contribute to developmental orthopedic disease, or DOD. In related 2025 coverage, The Horse reported that DOD is multifactorial, influenced by genetics, management, and nutrition, and warned that erratic concentrate changes, free-choice feeding, or sudden increases in ration size can create the uneven growth curves associated with orthopedic problems.

Other authoritative guidance fills in the practical details. AAEP recommends providing high-quality roughage free choice, supplementing with a properly balanced grain concentrate at weaning or earlier if needed, starting around 1% of body weight per day, dividing the ration into two to three feedings, removing uneaten feed, avoiding overfeeding, and ensuring unlimited fresh water and exercise. Clemson Cooperative Extension similarly advises close attention to mineral balance in young horses, especially calcium and phosphorus, with a target ratio as close to 2:1 as possible and never inverted. It also notes that young horses may need additional calcium, phosphorus, copper, and zinc during the first two years. (aaep.org)

Industry and expert-style commentary in the available sources is less about controversy than reinforcement. The Horse’s 2025 sponsored nutrition article, posted by Purina, pushes back on a common misconception that calories or protein alone cause DOD, arguing instead that imbalance across energy, amino acids, vitamins, and minerals is the more relevant risk. That article specifically highlights calcium:phosphorus balance of no less than 1:1, with 2:1 described as optimal, and a zinc:copper balance around 4:1 in the complete diet. Because the newly published 2026 piece is also sponsored content, veterinary readers may want to treat it as educational marketing rather than independent reporting, even though its basic recommendations are consistent with AAEP and extension guidance.

Why it matters: For equine veterinarians, nutrition consults around weaning and yearling development remain a meaningful preventive care opportunity. The main clinical takeaway is that “more” is rarely better in young horses. Overconditioning, abrupt ration changes, and poorly balanced homemade feeding plans can all undermine musculoskeletal development, while forage quality, concentrate formulation, mineral ratios, and growth monitoring all need to be considered together. That’s especially relevant in conversations with pet parents and breeders who may focus on topline or size gains without appreciating the orthopedic tradeoffs. (thehorse.com)

The new article itself doesn’t appear to announce a product launch, regulatory action, or new study. Instead, it reflects a broader trend: equine media and feed companies continue to invest in educational content around developmental risk reduction, likely because feeding decisions in the first two years have long-term implications for soundness, performance, and veterinary cost. For practices, that may be a cue to revisit client handouts, weaning protocols, and ration-review workflows, particularly for farms managing multiple young horses. This last point is an inference based on the recurring emphasis across the sources on early-life nutrition and long-term soundness. (thehorse.com)

What to watch: Watch for whether The Horse or Equus expands this into a broader series on foal and yearling nutrition, and for continued emphasis on ration balancing, forage analysis, and DOD prevention as young horses move from weaning into early training. (thehorse.com)
