Alcalde, a hulking black bull, is quite the stud. He sires up to 40 calves a year, most of them top-grade fighters, even though in human terms he'd be almost 80 years old and is nearing the end of his life.
Victoriano del Rio, a fifth-generation breeder of fighting bulls, cringes at the thought of losing a creature with such good genes. So he is going to clone him - an unprecedented marriage of technology and the Spanish-speaking world's ancient, beloved pastime.
"I am extremely fond of this bull," Del Rio said at his ranch in this town outside Madrid, watching 16-year-old Alcalde graze with some of his latest offspring - mere toys next to their prolific, half-tonne father. "He has given us tremendous satisfaction."
Del Rio is not alone in the adventure. Rancher Jose Manuel Fernandez in Mexico plans to replicate Zalamero, another revered, aging bull that achieved the rare feat of dodging death in the ring: In 1994 Zalamero put up such a relentless fight one autumn day that judges spared his life. Since then Zalamero, too, has been a priceless stud.
Fernandez is so bullish on cloning he envisions a future in which an afternoon at the arena - usually three matadors taking on two bulls each - might involve six genetically identical twins created from the same beast.
"What I am looking for is a path toward innovation in bullfighting," Fernandez said from Mexico City. "We are trying to give the show greater quality."
If all goes as planned, Zalamero II - or several of them, because Fernandez is trying for four or five - will be born in November or December of this year. Alcalde's clone would be born in May or June of next year.
Both breeders have hired ViaGen, a cloning company based in Austin, Texas, to do the job. The technique is essentially the same one used in 1996 to copy the sheep Dolly, the world's first cloned mammal.
A ViaGen spokesman, speaking on condition of anonymity, confirmed the orders from Del Rio and Fernandez, but would not comment on pregnancies or expected birth dates. He said the breeders would pay standard cattle cloning prices: US$17,500 for the first calf, US$15,000 for the second, US$12,500 for the third and US$10,000 for the fourth and beyond.
ViaGen has cloned about 300 mammals, including show pigs, rodeo horses and bucking broncos, since its founding in 2002. But this is the world's first go at cloning the breed that takes on matadors in the deadly minuet of bullfighting.
"It is a new field that is opening up before us," said Eduardo Miura, veteran breeder of a line of Spanish bulls so fierce the very word Miura has become part of the language (to "act like a Miura" is to become furious). He said breeders in Spain are generally supportive of Del Rio's cloning plans.
But question marks abound. It's one thing to pass on a carbon copy of a fighting or stud bull's DNA, quite another to expect the new animal to mimic its template.
Only as much as 40 percent of an animal's behavior is attributable to its genes, said Javier Canon, a geneticist at Madrid's Complutense University who specializes in fighting bulls.
External factors account for the rest.
And even if the sons of a great fighting bull were always great fighting bulls themselves there are much cheaper and more effective ways to harvest those valuable genes, such as using the father's semen for artificial insemination.
