SAO PAULO, Brazil – A Brazilian artist launched a subversive protest against the popular "CowParade" travelling art exhibit, which he deemed an affront to his country's homegrown art scene.

The popular CowParade urban art display brings dozens of brightly-colored life-sized resin cows to cities around the world, installing them in public spaces.

The exhibit is now on display in Sao Paulo, with individually decorated cows spread throughout the Brazilian city's streets.

But the seemingly-harmless art project, begun in Switzerland in 1998, raised the ire of local artist Eduardo Srur, prompting him to add his own element to the display -- randy bulls mounting the cow sculptures.

Srur's guerrilla art protest has each of the bulls grinning diabolically as it has its way with the hapless bovine sculptures.

"I fail to see the relationship between a cow imported from Switzerland and our country," Srur told the media here.

The cow art exhibit, he said, "is a sterile object, and the bulls have been introduced for a 'cultural insemination' -- to generate debate," he said.

Organizers failed to see the funny side and ordered the renegade bulls to be removed.
