Behavioral analysis of tiger night housing practices

Area of Science:

• Animal behavior and welfare science.
• Veterinary and zoological management.
• Comparative psychology.

Background:

• Ensuring optimal animal welfare necessitates evaluating changes in management practices.
• Aging animals may require specialized care, potentially disrupting established social housing.
• Tigers, typically social, present a unique case for assessing welfare impacts of temporary individual housing.

Purpose of the Study:

• To investigate the behavioral effects of intermittent individual overnight housing on adult female tigers previously housed socially.
• To identify behavioral indicators of positive or negative welfare changes associated with this housing shift.
• To assess the feasibility of temporary individual housing for aged tigers requiring specialized care.

Main Methods:

• Monitoring of specific behaviors including sleep duration and position, awake body posture, pacing, door pounding, self-grooming, roaring, and chuffing.
• Comparison of behavioral data between social housing and overnight individual housing conditions.
• Observation of six adult female tigers accustomed to social living.

Main Results:

• No significant differences were observed in time spent asleep, sleeping positions, or preferred awake body positions between housing conditions.
• Pacing, door pounding, and roaring behaviors were infrequent and unaffected by housing status.
• Self-grooming increased in individual housing, but without signs of over-grooming; chuffing, a social vocalization, was more frequent in social housing.

Conclusions:

• Intermittent individual overnight housing is a viable management strategy for social tigers requiring specialized care.
• The observed behavioral changes, such as increased self-grooming, did not indicate compromised welfare.
• Tiger welfare can be maintained during temporary transitions from social to individual housing arrangements.
