This document discusses animal welfare for 4th year DVM students. It introduces animal welfare as how an animal copes with its living conditions, and defines a state of good welfare as being healthy, comfortable, safe, and able to express natural behaviors without suffering. Good animal welfare requires disease prevention, appropriate shelter, nutrition, and humane treatment including handling and slaughter. The "Five Freedoms" are introduced as a framework to assess welfare, including freedom from hunger and thirst, discomfort, pain and disease, fear and distress, and freedom to express normal behaviors. The document emphasizes that animals experience feelings like sensations and emotions, and discusses whether animals can be considered moral agents.
