Variation in behavioral reactivity is associated with cooperative restraint training efficiency

Training techniques that prepare laboratory animals to participate in testing via cooperation are useful tools that have the potential to benefit animal wellbeing. Understanding how animals systematically vary in their cooperative training trajectories will help trainers to design effective and...

Intermittent pair-housing, pair relationship qualities, and HPA activity in adult female rhesus macaques

Laboratory rhesus macaques are often housed in pairs and may be temporarily or permanently separated for research, health, or management reasons. While both long‐term social separations and introductions can stimulate a stress response that impacts inflammation and immune function, the...

Infrared thermal imaging: Positive and negative emotions modify the skin temperatures of monkey and ape faces

Facial thermography has enabled researchers to noninvasively and continuously measure the changes of a range of emotional states in humans. The present work used this novel technology to study the effect of positive and negative emotions in nonhuman primates by...

Social hair pulling in captive rhesus macaques (Macaca mulatta)

Alopecia is common among captive populations of nonhuman primates. There are many potential causes of alopecia, including physiological conditions such as hormonal imbalance and infection, features of the captive environment such as housing type, ground substrate, and group density, as...

Higher levels of submissive behaviors at the onset of the pairing process of rhesus macaques (Macaca mulatta) are associated with lower risk of wounding following introduction

Social housing of rhesus macaques (Macaca mulatta) is considered to be the cornerstone of behavioral management programs in biomedical facilities. However, it also involves the risk of socially inflicted trauma. The ability to avoid such trauma would contribute to the...

Effects of human management events on conspecific aggression in captive rhesus macaques (Macaca mulatta)

Conspecific aggression in outdoor-housed rhesus macaques (Macaca mulatta) at primate research facilities is a leading source of trauma and can potentially influence animal wellbeing and research quality. Although aggression between macaques is a normal part of daily social interactions, human...

Comparison of saliva collection methods for the determination of salivary cortisol levels in rhesus macaques (Macaca mulatta), cynomolgus macaques (Macaca fascicularis), and African green monkeys (Chlorocebus aethiops)

The ability to quickly and accurately determine cortisol as a biomarker for stress is a valuable tool in assessing the wellbeing of NHP. In this study, 2 methods of collecting saliva (a commercial collection device and passive drool) and the...

Using a cageside device for testing glycosylated hemoglobin in cynomolgus macaques (Macaca fascicularis)

Recording an accurate body temperature is important to assess an animal's health status. We compared temperature data from sedated cynomolgus macaques (Macaca fascicularis) to evaluate differences between rectal, infrared (inguinal and chest), and implanted telemetry techniques with the objective of...

Pharmacokinetics of a novel, transdermal fentanyl solution in rhesus macaques (Macaca mulatta)

Rhesus macaques (Macaca mulatta) are the most commonly used NHP biomedical model and experience both research and clinical procedures requiring analgesia. Opioids are a mainstay of analgesic therapy. A novel, transdermal fentanyl solution (TFS) has been developed as a long-acting,...

Physiologic correlates of interactions between adult male and immature long-tailed macaques (Macaca fascicularis)

Interactions between adult males and immature members of the same species are rare in most mammals; in contrast, an estimated 40% of primate species are characterized by an involvement of males in the social life of infants and juveniles. The...
