Asian monkeys including rhesus, cynomolgus, and pigtailed monkeys; or African monkeys including baboons, African green monkeys, and patas monkeys.
Opaque Cages
Cages that are not transparent but receptive to changes in light, generally used to minimize animal stress levels.

- Natural opioids (i.e., opiates) include: opium and morphine
- Semisynthetic opioids include: heroine and oxycodone
- Synthetic opioids include: buprenorphine, tramadol and fentanyl
Orf
Contagious ecthyma, also known as orf or contagious pustular dermatitis, can cause crusting scabs anywhere on the body. Lesions are most frequently seen on the lips, nose, eyelids, tongue, ear, udder, and mucous membranes of sheep. In humans, the disease usually causes a firm, painful nodule on the hands or fingers. This localized lesion usually persists for 1-4 weeks.
Contagious ecthyma is transmissible to humans by direct contact with a lesion or with a contaminated fomite (e.g., bedding, equipment, manure, feed).
Outer Buildings
Buildings that are outside of Medical Campus and North Campus Research Complex such as: Pharmacy Building, East Hall, Undergraduate Science Building, Chemistry Building, School of Public Health Building, Kraus Building, Biological Science Building, Biomedical Engineering, and Natural Science Building.
Ovariohysterectomy
Surgical removal of the female reproductive organs.
Oversee
In the context of the Policy on the Authority and Responsibility of the Quality Assurance Program, oversee refers to conducting reviews of approved animal activities on behalf of the IACUC to ensure that governing standards are satisfied.
Overtime
Time spent providing services outside regular veterinary technician working hours (M-F 6 a.m.-5 p.m.), on weekends, and on holidays. Overtime charges will be calculated by business office personnel at a rate of 1.5 times the total time recorded during after hours/weekends/holidays.

Pair
Recommended breeding strategy using one adult female and one adult male resulting in a single litter. Takes advantage of postpartum estrus. Pair breeding has been proven to produce significantly more pups per female when compared to trio breeding and may be less stressful for both pups and dams than trio breeding.a,b

Pan Liner
A leak-proof pad with an absorbent paper or fabric top placed under the cage in the catch pan to collect waste product for easy disposal.
Panel Housed
Describes primates housed such that tactile contact is possible with another primate. This can be achieved via a panel with holes, mesh, grooming bars or other divider to limit access.
