How many healthy animals do {European} zoos put down?

When Copenhagen Zoo put down a healthy male giraffe earlier this month, much of the world was horrified. But those in the know say it's quite normal - a fate that befalls thousands of zoo animals across Europe every year.
"This is not a thing that should go anywhere outside Denmark," says Copenhagen Zoo's Scientific Director Bengt Holst, responding to the barrage of critical news coverage. "We all know it's done every day."
Every day? It's not actually quite that often, but Holst says it's difficult to give a precise number.
"We do it when it's necessary," he says. "If I should take an average over 10 years - it could be probably something like 20, 30 [per year]."
