阿德莱德大学与Monarto Safari Park合作进行的研究发现，为圈养非洲狮提供整只动物尸体并实施间歇性饲养制度，能够显著改变其进食行为，使其更加接近野生狮的自然模式1。这项研究在南澳大利亚的Monarto Safari Park进行，对三只成年雄性非洲狮进行了为期三个月的连续监测1。
研究使用八台红外摄像机记录了采用新饲养方式前后狮子的行为变化1。结果显示，当采用整只尸体饲养时，狮子的进食时间增加了近三倍，同时更多地进行撕扯和操控食物的行为，进食后的休息时间也显著延长1。禁食期间狮子的活动逐渐增加，整体节律与野生狮的进食周期相符1。研究中，三只狮子每九天获得约200公斤的整只动物尸体1。
首席作者Lesia Hryhorenko表示："野生狮不会每天在同一时间进食。它们会经历自然的进食和禁食周期，这取决于狩猎的成功。"1副教授Alexandra Whittaker补充道："许多动物园研究仅关注提供食物后立即发生的情况。我们的结果表明饲养计划可以影响其后数天的行为。"1
该研究已发表在《Applied Animal Behaviour Science》期刊2026年第301卷第107041页1。
Researchers from the University of Adelaide partnered with Monarto Safari Park in South Australia to investigate how feeding practices shape the behavior of captive African lions.1 The study involved three adult male lions that were provided with whole animal carcasses weighing approximately 200 kilograms every nine days, combined with an intermittent feeding schedule designed to mimic natural hunting cycles.1 Over three months of continuous 24-hour monitoring using eight infrared cameras, scientists observed significant behavioral shifts that brought the lions' routines closer to those of their wild counterparts.1
When fed whole carcasses on an intermittent schedule, the lions spent nearly three times longer eating than under standard feeding protocols.1 The animals engaged more frequently in tearing and manipulating their food, and they rested longer after consumption.1 During fasting periods, activity levels gradually increased, creating a rhythm aligned with wild lions' natural feeding cycles.1 According to lead researcher Lesia Hryhorenko, "Wild lions don't eat at the same time every day. They experience natural periods of feasting and fasting depending on hunting success."1 Associate Professor Alexandra Whittaker noted that previous zoo studies typically focus only on immediate post-feeding behavior, adding that "our results show that feeding schedules can influence behavior for days afterwards."1 The findings were published in Applied Animal Behaviour Science, volume 301, article 107041.1
