A rational approach to enriched nutrition for nonhuman primates

Obesity is a concern with nonhuman primates (NHPs) housed in captivity for extended periods of time, mostly due to overfeeding and lack of exercise. This is often compounded by environmental enrichment programs that include different types of food. That is...

Effects of positive reinforcement training on infant behavioral development in nursery-reared rhesus macaques (Macaca mulatta)

At the California National Primate Research Center, one key to long-term success of macaque breeding colonies is to develop effective infant-rearing strategies that minimize the emergence of behavioral pathologies, which can be one indicator of welfare. Positive reinforcement training (PRT)...

Stereotypic behaviors in singly housed rhesus macaques are significantly reduced during aquarium viewing

There was no habituation to the fish tank [1 hour per day for five days per week] during the 4-week exposure. We suggest that viewing aquaria containing fish can reduce stereotypic behavior in rhesus macaques.

Wood as an enrichment device for primates

Our facility houses approximately 300 cynomolgus macaques. Providing stimulating environmental enrichment for them without unreasonably increasing staff time can be challenging. Our current enrichment program includes multiple toys, mirrors, forage trays, sound machines, music, videos, and a variety of fruits,...

Acclimation and positive human interaction as methods to facilitate handling and reduce stress in captive cynomolgus monkeys (Macaca fascicularis)

Positive human interactions acclimated these 8 female cynomolgus macaques to standard handling and restraint techniques while reducing signs of distress.

Positive reinforcement training in rhesus macaques – training progress as a result of training frequency

Positive reinforcement training (PRT) efficiency was examined as a function of training frequency in 33 pair- or triple-housed female rhesus macaques. The animals were trained three times a week, once a day or twice a day, using PRT and a...

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)
