Animal Welfare Committee

Providing for good animal welfare encompasses both ethical and scientific responsibilities. AZA-accredited institutions have an ethical responsibility to ensure the well-being of the animals in their care. In addition, AZA-accredited institutions have a scientific responsibility to gain a greater understanding of the well-being of the animals in their care by advancing animal welfare science.

Animal Welfare Committee's Definition of Animal Welfare

Animal Welfare refers to an animal’s collective physical, mental, and emotional states over a period of time, and is measured on a continuum from good to poor.

Explanation: An animal typically experiences good welfare when healthy, comfortable, well-nourished, safe, able to develop and express species-typical relationships, behaviors, and cognitive abilities, and not suffering from unpleasant states such as pain, fear, or distress. Because physical, mental, and emotional states may be dependent on one another and can vary from day to day, it is important to consider these states in combination with one another over time to provide an assessment of an animal’s overall welfare status.

Animal Welfare Committee's Mission Statement

The AZA Animal Welfare committee promotes good welfare for animals in AZA-accredited zoos and aquariums, by assisting member institutions in identifying and applying best practices in animal welfare and through promoting advances in animal welfare science.

  • Encouraging the development of research projects and assessment tools to advance and monitor animal welfare.
  • Educating and engaging AZA zoos and aquariums in applying assessment tools.
