Obesity Epidemic Hits Zoo Animals
The News & Observer reports on a recent symposium at North Carolina State University dealing with overweight zoo animals:
Gorillas in the wild live on a bulky, low-calorie diet of such things as leaves, shoots and bark, but in zoos are often fed specially formulated biscuits.
The biscuits offer nutrition, but aren't bulky and don't fill up a peckish gorilla. That stresses out the primates and can lead to neurotic behavior. That also means that zoo gorillas -- who spend much of the day foraging in the wild -- have little to do, except sit around and look bored, the gorilla equivalent of hanging out on the sofa watching TV all day.
