The stress associated with transportation of non-human primates used in scientific research is an important but almost unexplored part of laboratory animal husbandry. The procedures and routines concerning transport are not only important for the animals' physical health but also for their mental health as well. The transport stress in cynomolgus monkeys (Macaca fascicularis) was studied in two experiments. In Experiment 1, 25 adult female cynomolgus monkeys were divided into five groups of five animals each that received different diets during the transport phase of the experiment. All animals were transported in conventional single animal transport cages with no visual or tactile contact with conspecifics. The animals were transported by lorry for 24 h at ambient temperatures ranging between 20°C and 35°C. Urine produced before, during and after transport was collected and analysed for cortisol by enzyme-linked immunosorbent assay (ELISA). All monkeys exhibited a significant increase in cortisol excretion per time unit during the transport and on the first day following transport. Although anecdotal reports concerning diet during transport, including the provision of fruits and/or a tranquiliser, was thought likely to influence stress responses, these were not corrobated by the present study. In Experiment 2, behavioural data were collected from 18 cynomolgus macaques before and after transfer from group cages to either single or pair housing, and also before and after a simulated transport, in which the animals were housed in transport cages. The single housed monkeys were confined to single transport cages and the pair housed monkeys were kept in their pairs in double size cages. Both pair housed and singly housed monkeys showed clear behavioural signs of stress soon after their transfer out of their group cages. However, stress-associated behaviours were more prevalent in singly housed animals than in pair housed animals, and these behaviours persisted for a longer time after the simulated transport housing event than in the pair housed monkeys. Our data confirm that the transport of cynomolgus monkeys is stressful and suggest that it would be beneficial for the cynomolgus monkeys to be housed and transported in compatible pairs from the time they leave their group cages at the source country breeding facility until they arrive at their final laboratory destination in the country of use.

Institut Pertanian Bogor (Bogor Agricultural University) has established a collaborative agreement with the Indonesian Ministry of State for Population and Environment and the United States Primate Research Consortium, consisting of the University of Washington Regional Primate Research Center (UW-RPRC), the Oregon Regional Primate Research Center (ORPRC), and the Bowman Gray School of Medicine at the Wake Forest University, to populate and manage a breeding facility of long-tailed macaques (Macaca fascicularis) on Tinjil island, a 6 km² island off the southern coast of West Java, Indonesia. Screening protocols have been established to select only simian retrovirus (SRV)-free animals for the colony. Animals originating in either West Java or Sumatra were individually caged and screened over a period of 3-5 months for the presence of SRV and tuberculosis. Whole blood specimens were taken from seronegative animals for virus isolation. Two months after the first screening, all negative animals were retested for SRV antibody and virus isolation. All animals remaining negative after this testing procedure and which have at least four consecutive negative TB tests were transported to the island. To date, 1,306 animals have been screened with 478 released to the island, and at least 750 babies were born on the island. Three batches of progeny of 45-50 juveniles each have been retrieved from the island, and are being used in AIDS-related research projects. [ABSTRACT FROM AUTHOR]
