These are modern breeds - not anywhere near the size and strength of the medieval breeds. And may I add that the British did much to bring new bloodlines.
Sir ,with all due respect I beg to defer from your argument.
I must say that :
1) the marwadi horse is an old breed, the ears are it's speciality.
The ears are turned inwards, the British considered it as a sigh of inferiority.
When a marwari horse and a horse from another breed mate, the turned ear in the offspring are not present . They are only present in pure breed native horses .
2) the fact of introduction of new blood lines by the British aforementioned is true, but they are a altogether different breed sir, called the English throughbred horse used by the army.
They don't have inwards curve ears, their endurance is not great either and they are more suitable to play equestrian sports , specifically polo which popularized them India.
The marwari is an ancient breed, atleast 1000 years old if not more, various legends about them are present in rajput folklore.
The marwari suffered a tremendous disaster after independence as many Royal houses became unable to maintain these horses,they sold them away and thus many were slaughtered for leather and at times even food by the poor. Who bought them at throw away prices.
The government being alarmed by the possible extinction of marwari has thus banned it's export Since independence.
Today this breed is being revived in rajasthan and punjab, average cost being 10 to 12 lakh for a average marwari, many are even sold for more than a crore at cattle fairs.
