Operant training differences between male and female group-housed nonhuman primates

Our study group consisted of 16 male (2.24-2.80 kg) and 16 female (1.96-2.91 kg) Chinese cynomolgus macaques (Macaca fascicularis), 2.5-3.5 years of age, that were housed in groups of 4. Our goal was to train the animals to come to...

Developing a reliable laboratory primate alopecia scoring system for interfacility collaboration and on-line training

Of the potential flags of impaired well-being in laboratory primates, alopecia has received particular regulatory focus, making it a top priority for behavioral managers. Consensus on a reliable alopecia scoring system used by multiple facilities can better determine prevalence and...

Risk factors and remediation of self-injurious and self-abuse behavior in rhesus macaques

Considered signs of decreased welfare--abnormal behaviors such as self-injury and self-abuse among nonhuman primates housed in the laboratory--may put into question the validity and reliability of scientific research using these animals as models. Providing environmental enrichment decreases the incidence of...

Grandmothers care for orphans in a provisioned troop of Japanese macaques (Macaca fuscata)

This study reports cases in which grandmothers and other closely related adult females cared for orphans in the Arashiyama E-troop, a provisioned troop of Japanese macaques (Macaca fuscata). I observed the behavioral patterns of three orphans (aged 1, 2, and...

Behavioral response of rhesus macaques (Macaca mulatta) to routine cage washing procedures

Documenting behavioral effects of routine procedures such as the cage washing process in nonhuman primate facilities is an important step in identifying procedures that may be stressful to the primates, and in determining ways to improve those procedures. Collecting 210...

Self-directed biting in male rhesus monkeys (Macaca mulatta) with self-injurious behavior (SIB) increases following acute treatment with the anxiogenic drug FG7142

A small percentage of captive macaques spontaneously exhibit self-injurious behavior (SIB), mostly in the form of self-directed biting. Several risk factors have been identified in the etiology of SIB in monkeys, including exposure to early life stressors. We hypothesize that...

Primate location preference in a double-tier cage: The effects of illumination and cage height

Across conditions, monkeys showed a strong preference for the upper row of a standard double-tier cage. If financial or spatial constraints require that some animals be housed in the lower row, we suggest providing these animals with regular access to...

Applications of positive reinforcement training in captive orangutans (Pongo pygmaeus) and Taiwanese macaques (Macaca cyclopsis)

PRT is a good way of shaping the behavior of captive animals and doing so can make the animals less stressed to promote their well being. PRT is commonly used by captive animal organizations in many countries, but not in...

Assessment of efficacy of three types of foraging enrichment in rhesus macaques (Macaca mulatta)

Rhesus macaques housed indoors in captivity commonly display abnormal behaviors that are rarely seen in their wild counterparts. These behaviors include stereotypic behaviors and self-abuse. These behaviors are often seen as signs of poor welfare, due to stressors in the...

Rate of self-injurious behavior in buspirone-treated rhesus macaques (Macaca mulatta) across different levels of human activity in the environment

This study examined the effectiveness of an anxiolytic drug, buspirone, in rhesus macaques with a history of self-injurious behavior. ... However, self-biting was more prevalent during periods of high activity. Treatment with buspirone was not associated with decreased time in...
