Welfare science

Animal welfare refers to an animal's collective physical, mental, and emotional states, measured from poor to excellent. By monitoring an animal's behavior, body condition and reproductive and stress hormones, we can form a clearer picture of its physical and psychological state. That information helps us better care for animals and improve their quality of life.
