But farmer Dave Joyce used Viagra to help enhance Boris' sex drive at Heronsbrook Farm, Solihull, West Midlands.
Boris was given a diet of herbal Viagra for a week and just two days before the French Limousin was to be sent to the slaughterhouse he regained his sexual vigour.
"He just couldn't perform and we just thought - he's got to go. He was destined for the slaughterhouse," the Sun quoted Dave, as saying.
He went on: "But he is such a nice bull and we didn't really want to get rid of him so we started looking into alternative solutions.
"Since the herbal treatment we have never seen him so rampant. hen the cows come out - he's the first in there.
"Now he is totally on the straight and narrow and calves are back on the agenda.
"It means we don't have to turn him into burgers. He is on a rigid regime of the herb formula in his daily feed."
Dave's assistant Rob Smith, 52, came across the product on the Internet. The capsules are mixture of Horny Goat Weed, Cordyceps, Damiana, Avena Sativa and Muira Puama, all of which claim to revive one's sex life.
Dave, 41, added: "Boris couldn't finish off what he started with the cows. For some reason his tackle would veer off at 45 per cent at the vital moment and all was lost. But after a few days of the treatment Boris was back to his randy old self." (ANI)
