Two methods of social separation for paired adolescent male rhesus macaques (Macaca mulatta)

Literature-based recommendations regarding how to separate pairs of laboratory-housed NHP when required for research, veterinary, or management needs are unavailable. This study assessed 2 separation techniques—rapid and stepwise—to determine whether a period of limited social access mitigates the behavioral stress...

Evaluation of a zinc gluconate neutralized with arginine product as a nonsurgical method for sterilization of rhesus macaques (Macaca mulatta)

Because rhesus macaques (Macaca mulatta) are prolific breeders, overpopulation can be problematic in both research and feral populations. Currently, the most effective contraceptive methods are hormonal control in female macaques and vasectomies in males. These methods each come with innate...

Comparison of direct and indirect methods of measuring arterial blood pressure in healthy male rhesus macaques (Macaca mulatta)

Blood pressure is a critical parameter for evaluating cardiovascular health, assessing effects of drugs and procedures, monitoring physiologic status during anesthesia, and making clinical decisions. The placement of an arterial catheter is the most direct and accurate method for measuring...

Effect of chronic social stress on prenatal transfer of antitetanus immunity in captive breeding rhesus macaques (Macaca mulatta)

Because tetanus can cause significant morbidity and mortality in NHP, colonywide vaccination with tetanus toxoid is recommended for outdoor breeding colonies of rhesus macaques, with primary immunizations commonly given to infants at 6 mo of age followed by booster vaccines...

Porches as enrichment for singly housed cynomolgus macaques (Macaca fascicularis)

Effective environmental enrichment is used by animals, promotes species-typical behavior, and decreases abnormal behavior. Porches attached to the front of an animal's cage provide additional space, perching opportunities, and a better view of the surroundings. Here we assessed the effectiveness...

Tailored enrichment strategies and stereotypic behavior in captive individually housed macaques (Macaca spp.)

The welfare of nonhuman animals in captivity is widely dependent on the natural psychological, physical, and behavioral needs of the animals and how adequately these needs are met. Inability to engage in natural behaviors can lead to chronic stress and...

Non-invasive detection and successful treatment of a Helicobacter pylori infection in a captive rhesus macaque

Gastritis is a commonly diagnosed condition in non-human primates used in biomedical research. As in humans, Helicobacter pylori infection may cause gastritis. The following report presents a method of non-invasive detection and a successful treatment protocol for this common pathogen.

Does mirror enrichment improve primate well-being? Animal Welfare 25(2), 163-170

Primates are highly social animals and appropriate enrichment is required to ensure their psychological well-being. Mirrors are sometimes used as social or sensory environmental enrichment. In this paper we investigate the suitability of mirrors as enrichment for captive primates, by...

Assessment of stress responses in rhesus macaques (Macaca mulatta) to daily routine procedures in system neuroscience based on salivary cortisol concentrations

Non-human primates participating in neurophysiological research are exposed to potentially stressful experimental procedures, such as dietary control protocols, surgical implants and their maintenance, or social separation during training and experimental session. Here, we investigated the effect of controlled access to...
