A study conducted by Adelaide University and Monarto Safari Park examined how feeding practices influence lion behavior in captivity. Researchers monitored three adult male African lions over three months using infrared cameras, comparing their behavior before and after whole animal carcasses were introduced as part of a nine-day feeding cycle that alternated between availability and fasting periods.
During carcass feeding days, the lions spent nearly three times longer eating compared to their standard feeding routine. The animals engaged in natural behaviors such as tearing, pulling, and manipulating food over extended periods. Following these intensive feeding sessions, the lions exhibited considerably longer rest and digestion periods. As the fasting interval progressed, their activity levels gradually increased again, creating a cyclical pattern resembling documented feeding rhythms in wild lion populations.
Researchers tracked additional behavioral indicators including pacing and social interactions. Pacing activity increased slightly overall but did not correlate consistently with hunger duration. Instead, larger increases occurred around predictable events such as keeper arrivals, suggesting pacing may be more strongly linked to routine expectations than to food scarcity. No significant aggression or disruption to social stability occurred during the carcass feeding events.
The findings indicate that feeding schedules influence lion behavior across extended periods beyond individual feeding events. Lead researcher Lesia Hryhorenko noted that providing whole carcasses offers lions opportunities to engage in natural feeding ecology behaviors. Associate Professor Alexandra Whittaker emphasized that comprehensive behavioral monitoring across complete feeding cycles is essential for evaluating zoo management practices. Researchers recommend combining future behavioral observations with physiological measurements to develop a more complete assessment of how different feeding strategies affect animal welfare.
