Responses to Reduced Feeding Frequency in Captive-Born Cheetahs (Acinonyx jubatus): Implications for Behavioural and Physiological Stress and Gastrointestinal Health

SIMPLE SUMMARY: This study examined how offering larger quantities of food less frequently to better replicate their natural feeding pattern could affect the health of captive-born cheetahs. For three weeks, six hand-reared cheetahs were fed four once-daily meals per week, followed by three weeks in which they were fed two daily rations six days a week for the same duration while maintaining their total weekly food intake. The studied cheetahs showed higher faecal consistency scores and activity levels when fed less frequently. The results indicate that reducing feeding frequency could benefit captive cheetahs’ gastrointestinal health without causing significant stress. ABSTRACT: Unnatural diet composition and frequent feeding regimes may play an aetiological role in the multiple diseases prevalent in captive cheetahs. This study investigated the responses of captive-born (hand-reared) cheetahs (n = 6) to a reduced feeding frequency schedule distinguished by offering larger quantities of food less frequently. The study cheetahs were fed four once-daily meals per week during the 3-week treatment period, followed by a 3-week control period in which they were fed two daily rations six days a week. Total weekly food intake was maintained throughout the study. Variations in behaviour, faecal consistency score (FCS), and faecal glucocorticoid metabolite concentration were measured. Less frequent feeding resulted in higher FCS (p < 0.01) and locomotory behaviour (p < 0.05) among the studied cheetahs. Faecal glucocorticoid metabolite concentration demonstrated an initial acute stress response to the change in feeding frequency (p < 0.05) and subsequent adaptation. The results of the FCS analysis suggest that the more natural feeding pattern could have benefited the studied cheetahs’ gastrointestinal health without a significant behavioural or physiological stress response overall to the change in feeding frequency.
