Origin and history
The Thoroughbred originated from the crossing of native English mares with three imported Oriental foundation sires: the Darley Arabian, the Godolphin Arabian, and the Byerley Turk. These crosses were made with the aim of creating a fast and enduring horse for racing. The breed was officially recognized with the publication of the General Stud Book in 1791, which lists purebred lineages. Today, it is the most influential breed in the world of horse racing.

The quintessential sport horse, the Thoroughbred presents a slender and athletic build, with a long-lined frame and fine but strong bone structure. It exudes an impression of power and speed.
Fine and expressive head, often with a straight or slightly concave profile. The eyes are large and lively, the nostrils wide, and the ears well-shaped and mobile.
Long, fine, and well-muscled neck, harmoniously set into high and prominent withers, characteristic of the breed.
Relatively short and taut back, muscular topline. Deep and well-sprung chest, providing ample lung capacity. Long and muscular croup, often slightly sloped, conducive to propulsion.
Long, fine, and clean limbs, with well-defined joints and clean tendons. The cannons are short and the pasterns of medium length. The feet are generally small and hard. No feathering.

Feeding the Pur-sang Anglais
The Thoroughbred is a demanding athlete with a fast metabolism. It requires a rich and balanced diet to support its performance and maintain muscle mass. It does not generally tend to be overweight but requires a high caloric intake, often in the form of energy-rich concentrates (grains, compound feeds) in addition to good quality forage in sufficient quantity.
Although generally robust, the Thoroughbred can be sensitive to dietary imbalances, particularly in cases of a diet too rich in starch or sudden changes, which can lead to colic or gastric ulcers. It does not have a documented breed-specific predisposition to laminitis or EMS, but an unsuitable diet can always pose risks.
With Equio, every feed, supplement or treat is read against the horse's real profile (age, weight, Body Condition Score, conditions) — useful for a Pur-sang Anglais as soon as a metabolic or digestive sensitivity is known.
Health and points to watch
Regular monitoring of the musculoskeletal system is essential due to the stresses of racing and sport. Particular attention must be paid to digestive (ulcer prevention) and respiratory health. Regular veterinary follow-up is essential to detect and manage conditions early.
- Documented genetic disorders: Osteochondritis dissecans (OCD) - multifactorial predisposition, Exercise-induced pulmonary hemorrhage (EIPH) - genetic and environmental predisposition
- More frequent conditions: Gastric ulcers, Colic, Joint problems (osteoarthritis, tendonitis) related to training intensity, Stress fractures, Respiratory problems (EIPH, inflammatory airway diseases)
Care and grooming
The hooves, often small, require trimming and shoeing adapted to intense athletic activity. The mane and tail are generally fine and do not require special care, apart from regular brushing. The fine and shiny coat is easy to maintain, but clipping is often necessary for racehorses in winter. Good general hygiene and skin care are important to prevent skin conditions.

Equio lets you build a complete profile for a Pur-sang Anglais: 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
