Feeding the Mérens
The Mérens is a hardy horse with an economical metabolism, accustomed to harsh living conditions and a poor diet. It tends to gain weight if overfed. Its diet should primarily consist of good quality forage (hay, grass) in sufficient quantities. Concentrates are only necessary in cases of intense work or specific needs (gestation, lactation), and should be given sparingly to avoid excesses.
Due to its economical metabolism, the Mérens can be predisposed to Equine Metabolic Syndrome (EMS) and laminitis if subjected to a diet too rich in sugars and starch, or if it is overweight. Careful dietary management is crucial 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 Mérens as soon as a metabolic or digestive sensitivity is known.
Health and points to watch
Carefully monitor the horse's weight and adjust the diet accordingly. Regular and appropriate hoof trimming is essential, given their crucial role on difficult terrain. Particular attention should be paid to the quality of conformation and the condition of the joints, especially in older or heavily worked horses.
- More frequent conditions: Laminitis (in case of overfeeding), Equine Metabolic Syndrome (EMS), Joint problems related to age or excessive work on hard ground
Care and grooming
The Mérens' hooves are naturally hard and resistant, requiring regular trimming but often less intensive than other breeds. The mane, tail, and feathering are abundant and thick, requiring regular detangling to prevent knots and dirt accumulation. The dense coat protects it well from the cold; clipping is generally not necessary except for sport horses in intense work. Monitoring the skin under the feathering is recommended to prevent mud fever.
