Rhesus and cynomolgus macaques are some of the most frequently utilized laboratory nonhuman primates, and it is common for one facility to have a significantly large colony of either or both species. Daily care needs...
Positive reinforcement training relies on identifying an effective reinforcing consequence, often food, to be presented contingent on the performance of the desired behavior. Prior to training sessions, we used a multiple stimulus without replacement (MSWO)...
The pole and collar method enables safe transfer of a monkey from their home environment to a restraint chair without sedation. The ability to conduct procedures with a conscious and cooperative subject is cost effective...
The quality of human-animal interactions can be an indicator of well-being in laboratory primates and increased anxiety-related behavior, such as aggression, may compromise an animal’s ability to provide research outcomes reflective of normal function. The...
The discussion was started by the following questions: "Is the squeeze-back mechanism more or less stressful than the pole and collar system for removing a macaque from his cage for an IM (intramuscular) injection?" and...
Studies have shown chimpanzees can learn to perform tasks by watching live or videotaped demonstrators. The present study assessed whether female chimpanzees exposed to a videotaped demonstrator would learn a husbandry-related task, urinating into a...
At the Oregon National Primate Research Center, we train animals to enter transfer boxes using positive reinforcement training (PRT), a type of training in which the trainer reinforces desired behaviors (such asentering the transfer box)...
Clicker training minipigs provides a significant improvement in the dermal dosing procedures.
The use of dogs in research has been under increasing public scrutiny and criticism over the past several years, and our institution has been no exception. Of particular concern is the use of Class B...
Recently a researcher approached our large animal facility manager about housing 19, 2-mo-old piglets and assisting with data collection. Part of the protocol required that the piglets be fed an individually measured high-sugar/high-fat diet over...
