THis course The path of true love never went smoothly. That’s especially true when your lover weighs 0.5 tonnes and wears steel shoes. The breeding season is in the National Stud of Newmarket, the town of Suffolk, widely known as the home of thoroughbred horse racing. The mare stands behind the stables. Her hooves are covered with leather boots to weaken the kick. Her head is embraced by the groom. Stud’s director, Tim Lane, calms her down. Horses are brushed until they shine like horse chestnuts and “must look good,” Lane explains. Look carefully at each other.
Thoroughbreds are ridiculous world aristocrats. It’s more than inbreeding, with fascinating and bizarre mating rituals. All are descendants of three Arabian stallion brought to England around 1700. According to Charles Darwin, animals with “mixed Arab, Turkish, spine” veins. They make the Habsburgs look genetically diverse.
Thoroughbreds, which are always closely related, are becoming more and more so.Recent studies published in Science report “In the last 50 years, the inbreeding of the Thoroughbred population in the world has increased significantly.” All but 3% of the 10,000 horses surveyed counted Northern dancers born in 1961 as their ancestors. Superstar bulls “cover” more than 200 mares a year, from 40 on Northern Dancer Day, as horse-like types call mating.
Initially, horse breeders did not consider the issue of inbreeding. On the contrary, like a maiden, the horse should have been purer. Within a century of the arrival of these three horses, the task of completing the horses was so successful that the pedigree register was determined to be closed to new entrants. The aristocrats cracked down on their horse parenthood and listed their dams and bulls in the Weatherbys pedigree register. With the introduction of Burke’s Peerage in 1826, aristocrats were able to do much the same for themselves. Eugenics father Francis Galton recommended that “you shouldn’t lose time” to record fitness and form, not class, when establishing a person equivalent to a pedigree certificate.
Eugenics is obsolete. I don’t have an equivalent like a horse. Thoroughbreds can make a lot more money by spreading the race than running the race. The National Stud charges a £ 25,000 ($ 35,000) fee for the cover. Galileo, one of the best stallions in the world, is rumored to order £ 600,000 per pop.
Such a fee makes the best thoroughbred semen one of the most expensive substances in the world and costs around £ 6 million per liter. The exact amount is difficult, but it’s definitely a profitable business, as it’s not sold in bottles (horses born by artificial insemination cannot be registered as thoroughbreds) and the quantity naturally fluctuates. The finest stallions can earn £ 1m a day.
Therefore, fashionable bulls are suitable for breeders. But they may be bad for the variety. As genetic mutations accumulate, health and childbirth decline. Such problems have been found in a variety of species such as dogs, humans and cattle, and it is difficult to understand why horses are unaffected by them. “We still don’t know how much inbreeding is acceptable, if we’ve reached a turning point, or when we’ll reach a turning point,” said Emmeline Hill of University College Dublin, one of the authors of a recent report. I am. Genetic problems have accumulated and may be invisible.
Return to The National Stud, the gleaming horse, the cover is complete, and return to Nikko to trot. Like Hill, Lane believes that not only appearance but also function is important. Good-looking horses may not compete well or breed well. While teasing, he reaches for similarities with another species. “Not all cool women can cook, right?” ■■
