Animal Welfare in Conservation Breeding: Applications and Challenges

Area of Science:

• Zoological Husbandry
• Conservation Biology
• Animal Welfare Science

Background:

• Animal welfare and conservation breeding share goals but can diverge.
• Conservation breeding requires preparing animals for potential release, necessitating a balance between welfare and minimizing captivity effects.
• Endangered Hawaiian bird species are housed in captive breeding facilities.

Purpose of the Study:

• To outline an outcome-based welfare strategy for conservation breeding facilities.
• To detail management inputs and evidence-based evaluation methods for improving welfare.
• To address challenges in enhancing welfare within conservation breeding contexts.

Main Methods:

• Implementing "Opportunities to Thrive" guiding principles.
• Utilizing husbandry, nutrition, behavior-based enrichment, and integrated veterinary practices.
• Monitoring welfare and input effectiveness through an evidence-based approach, including remote veterinary exams and parental rearing transitions.

Main Results:

• Development of species-typical behaviors in captive animals.
• Improved captive animal welfare through targeted management strategies.
• Establishment of an outcome-based welfare strategy for conservation breeding.

Conclusions:

• Balancing high welfare with minimized captivity effects is crucial for population sustainability.
• An evidence-based approach is essential for evaluating and improving welfare outcomes in conservation breeding.
• Future steps are outlined for enhancing and evaluating welfare that aligns with conservation objectives.
