3. ANIMAL CATEGORIES

Per federal regulations, experimental procedures are categorized according to their potential for causing pain or distress to animal subjects. You must designate categories for all study animals.

USDA Category Definition
C Animals upon which teaching, research, experiments, or test were conducted involving no pain, distress, or use of pain-relieving drugs.
D Animals upon which experiments, teaching, research, surgery, or tests were conducted involving accompanying pain or distress to the animals and for which appropriate anesthetic, analgesic, or tranquilizing drugs were used.
E
Animals upon which teaching, experiments, research, surgery or tests were conducted involving accompanying pain or distress to the animals and for which the use of appropriate anesthetic, analgesic, or tranquilizing drugs would have adversely affected the procedures, results, or interpretation of the teaching, research, experiments, surgery, or tests. (An explanation of the procedures producing pain or distress in these animals and the reasons such drugs were not used must be attached to the USDA Annual Report).
An animal is counted:
* only once per year, even if it was used in more than one Protocol
* in the most painful/distressful Category, if used in more than one category
