The thoroughbred sire Brave Mansonnien, a rare genetic
The three founding stallions of the English thoroughbred breed are of foreign origin: Darley Arabian comes from Syria where he was acquired by an English merchant named Thomas Darley; Godolphin Arabian came from Morocco and had been offered to Louis XV by the caliph, he was then bought by the Englishman Edward Coke, while he was used to pull carts; Byerley Turk was a horse used by the Ottoman army, captured by an English soldier ...

The legend of Byerley Turk
The dark bay stallion was captured by the English captain Robert Byerley in 1687 during the siege of Buda (Hungary) by the Ottomans - hence its original name: Byerley's Turk. The soldier had noticed this very beautiful and very fast little horse. According to the legend, the stallion was also so fast and fiery that it took several days of tracking to succeed in capturing him. Captain Byerley used it during other campaigns in Ireland

Dangers of inbreeding and the necessity to preserve male lines in thoroughbreds. Dr B. Stoffel
This subject was presented at the recent 2023 general assembly of the EFTBA (European Federation of Thoroughbreds breeders Associations).
Inbreeding - a concern of many breeders - is the proportion of genes carried by the chromosomes inherited identically from both parents.
Situation of inbreeding in the Thoroughbred breed
The Thoroughbred breed has low genetic diversity compared to most other horse breeds, given its low population numbers and a trend of increasing inbreeding. This trend in the global Thoroughbred population has been reported for the past few decades and is unlikely to stop due to current breeding practices. 97% of the pedigrees of the horses included in a recent study include the paternal ancestor, Northern Dancer (1961) and 35% and 55% contain Saddler's Wells (1981) and Danehill (1986), respectively in Europe and Oceania.

Hyaluronic acid
Sodium hyaluronate has been found present in the synovial fluid of all species studied. In humans it is also found in other soft connective tissues such as skin, umbilical cord, and vitreous humour as well as being present in lung, kidney, brain, and muscle tissues. Scientific understanding of the underlying properties of sodium hyaluronate started in 1934, when it was isolated from bovine vitreous humour Since the 1950s, the litterature concerning the potential therapeutic use of sodium hyaluronate in humans has grown.
The viscoelastic properties of synovial fluid in the joint are known to due to its sodium hyaluronate content. Changes in the lubricating properties of synovial fluid, lead to significant pain and loss of function.
In pathological conditions, due to acute and chronic inflammation, the synovial fluid no longer exhibits its normal rheological properties that protect the synovial tissue and cartilage from mechanical stress.
