Which group of animals is primarily covered by the USDA/AWA?

The group of animals primarily covered by the USDA/AWA (Animal Welfare Act) includes most warm-blooded animals, which typically refers to mammals and birds. The USDA/AWA is designed to ensure humane treatment and welfare standards for animals used in research, exhibition, and as pets.

This legislation covers animals that are domesticated or have a significant history of association with humans, mainly focusing on those that are warm-blooded, because they typically require more stringent welfare considerations due to their physiological and behavioral complexities.

While the Act does include some provisions for certain species of birds and mammals, it notably excludes many cold-blooded animals, such as reptiles, amphibians, and fish, from its primary coverage. Therefore, the correct identification of the group regulated primarily under the USDA/AWA is warm-blooded animals.
