Feeding the Cheval Yonaguni
The Yonaguni Horse is a very thrifty breed, accustomed to limited resources. Its metabolism is adapted to a poor diet, and it tends to become overweight if the intake is too rich. It primarily subsists on coarse forage such as grass and hay. Concentrates are generally not necessary, except in cases of intense work or specific needs, and should be introduced sparingly.
Due to its thrifty metabolism, the Yonaguni Horse can be predisposed to Equine Metabolic Syndrome (EMS) and laminitis if overfed or exposed to pastures too rich in sugars. Careful monitoring of its weight and diet is essential to prevent these conditions.
With Equio, every feed, supplement or treat is read against the horse's real profile (age, weight, Body Condition Score, conditions) — useful for a Cheval Yonaguni as soon as a metabolic or digestive sensitivity is known.
Health and points to watch
It is important to monitor its weight and adapt its diet to avoid obesity and associated metabolic problems. Particular attention must be paid to the condition of its hooves, which are naturally very resilient but require regular trimming to maintain their integrity.
- More frequent conditions: laminitis, Equine Metabolic Syndrome (EMS)
Care and grooming
The Yonaguni Horse's hooves are naturally hard and resilient, requiring regular but often less intensive trimming than other breeds. Its mane and tail are thick and may require occasional detangling. Its hardy coat does not require special care, and clipping is rarely necessary.
