The breed was officially recognized in 1996, and a conservation program is in place to preserve this unique genetic heritage.

Feeding the Castillonnais
The Castillonnais is a hardy and economical horse, accustomed to harsh mountain conditions. Its metabolism is efficient, making it undemanding in terms of feed. It makes very good use of medium-quality roughage. Concentrates are only necessary in cases of intense work or specific needs (gestation, lactation), and should be given sparingly to avoid obesity.
Due to its economical metabolism, the Castillonnais can be prone to obesity if overfed or if it has unlimited access to overly rich grass, which can increase the risk of laminitis and Equine Metabolic Syndrome (EMS). It is therefore important to monitor its weight and adapt its diet.
With Equio, every feed, supplement or treat is read against the horse's real profile (age, weight, Body Condition Score, conditions) — useful for a Castillonnais as soon as a metabolic or digestive sensitivity is known.
Health and points to watch
The breed's hardiness limits specific health problems. Body condition should be monitored to prevent obesity and associated risks. Particular attention should be paid to hoof care, as the hooves are naturally hard but require regular trimming.
- More frequent conditions: laminitis (if overfed), age-related joint problems (like any breed)
Care and grooming
The Castillonnais' hooves are renowned for their hardness and resistance, requiring regular trimming but often less frequent than other breeds. The mane and tail are full and can be left natural or maintained according to use. The hardy coat requires no special care, and clipping is rarely necessary except for sport horses in intense work.
Did you know?
- The Castillonnais is one of the few equine breeds to predominantly exhibit the black pangaré or bay pangaré coat, characterized by lighter areas around the muzzle, eyes, belly, and inner thighs.
- It is nicknamed the 'mountain horse' due to its perfect adaptation to steep terrain and its ability to live in semi-freedom.
- The breed was saved from extinction thanks to the mobilization of passionate breeders and the creation of the National Association of the Castillon Horse (ANCC).
The Castillonnais and how to track it
The Castillonnais breed is primarily bred in its native region, the Ariège Pyrenees. Its population remains low and is subject to an active conservation program, with gradual dissemination for trekking and leisure.
Equio lets you build a complete profile for a Castillonnais: identity, weight, Body Condition Score, feeding, conditions, care reminders (vaccines, worming, trimming) and an exportable health log. The breed sets the identity; everyday decisions still depend on the real horse and your vet's advice.
- Record the activity level: rest, leisure, sport or breeding
- Add known conditions or sensitivities
- Scan feeds, plants and care products
- Keep reminders (vaccines, worming, trimming)
- Prepare a PDF export before a vet appointment
