The idea of feeding zoo-housed animals in a way that mimics their natural behaviors is an intriguing one, and a recent study from Australia has shed light on this concept with its focus on lions. The research, published in Applied Animal Behaviour Science, reveals that feeding lions whole animal carcasses on a feast-and-fast schedule can significantly impact their behavior, making it more wild-like.
The study, conducted by Adelaide University and Monarto Safari Park, involved monitoring three adult male lions over three months using around-the-clock video surveillance. The lions were fed whole carcasses every nine days, mimicking the natural hunting and feasting patterns of wild lions. The results were fascinating, to say the least.
Firstly, the lions spent significantly more time feeding on carcass days, almost three times longer than their normal feeding duration. This extended feeding time allowed them to engage in a wider range of natural feeding behaviors, such as tearing and manipulating the carcasses. After meals, the lions rested more, and as the fasting period progressed, their activity levels gradually increased, creating a behavioral rhythm that closely resembled the natural feast-and-fast cycles of wild lions.
This study highlights the importance of feeding schedules in shaping the behavior of carnivores in human care. Lesia Hryhorenko, the lead author, emphasizes that wild lions don't eat at the same time every day and that their feeding patterns are influenced by hunting success. By introducing a feeding routine that mirrors these natural patterns, the lions in the study exhibited more natural behaviors.
One interesting finding was the impact of pacing, a repetitive behavior often associated with anticipation in carnivores. While pacing increased slightly, it was not directly linked to hunger but rather to predictable feeding routines. This suggests that pacing in these lions was more of a response to the routine of their caregivers rather than an indication of hunger.
The study also found no increase in aggression or social instability around carcass feeding events, which is a positive outcome for the lions' overall well-being. This is crucial information for zoo management, as it indicates that this feeding method can be implemented without causing undue stress or disruption within the lion community.
The researchers emphasize the value of long-term, continuous monitoring in assessing animal behavior and management practices. Many zoo studies focus on immediate post-feeding behaviors, but this research shows that feeding schedules can influence behavior for days afterward. Therefore, it is essential to consider the entire feeding cycle when studying animal behavior.
In conclusion, this study provides valuable insights into how feeding schedules can shape the behavior of zoo-housed animals, particularly carnivores. By mimicking natural hunting and feeding patterns, we can enhance the well-being and natural behaviors of these animals, which is a significant finding for the field of animal care and conservation.
