What to know about Zoo-housed lions show wild-style behaviors when fed whole carcasses

A study by Adelaide University and Monarto Safari Park found that feeding zoo-housed lions whole carcasses on a feast-and-fast schedule encourages behaviors similar to those of wild lions. Researchers observed increased feeding time and resting periods that mirrored natural cycles, while noting that pacing behavior was linked to routine cues rather than hunger.

Zoo-housed lions show wild-style behaviors when fed whole carcasses Sadie Harley Scientific Editor Robert Egan Senior Editor A new Australian study has found that feeding zoo-housed lions whole-animal carcasses on a feast-and-fast schedule encourages…

Why it matters

Published in Applied Animal Behaviour Science, the research from Adelaide University and Monarto Safari Park in South Australia examined how African lions responded when animal care staff introduced whole-animal carcasses every nine days, building on an…

Common ground

Using around-the-clock video monitoring over three months, researchers found the lions spent significantly longer feeding, rested more after meals and displayed activity patterns that mirrored the natural cycles of wild lions.
