Effects of play caging on the behavior and enrichment use of singly-housed rhesus macaques

This study examined whether allowing 10 singly-housed adult male rhesus macaques (Macaca mulatta) 2-week access to a larger play cage would increase their species-typical behavior and decrease anxiety and abnormal behavior. The play cage consisted of four interconnected cages equipped...

Efficacy of 3 types of foraging enrichment for rhesus macaques (Macaca mulatta)

The 3 enrichment devices had different effects on individual expression of stereotypy: supertubes decreased it, shakers increased it, and puzzle balls led to a decrease followed by an increase. We present potential reasons for the changes in stereotypy and postulate...

Going back to nature: The benefits of wood enrichment

Environmental enrichment can be defined as altering the living environment of captive animals in order to provide them with opportunities to express more of their natural behavioral repertoire. The challenge of providing effective enrichment in laboratory species is to ensure...

Refinement of a macaque transplantation model: Application of a subcutaneous port as a means for long-term enteral drug administration and nutritional supplementation

A new application of a device enabling the long-term enteral administration of drugs or nutritional supplementation was developed for implementing in research entailing the use of macaques (Macaca fascicularis). After implanting a subcutaneous port, a surgically-placed gastrostomy (SPG) was completed...

Improving the efficiency of positive reinforcement training for non-human primates

There are many benefits of positive reinforcement training (PRT). PRT reduces stress for subjects and as such is a significant refinement to animal care practices. However, training can be time intensive, and not all animals easily learn tasks, which may...

Enrichment object preferences in laboratory rhesus monkeys (Macaca mulatta)

To promote the psychological well-being of captive non-human primates, facilities develop and implement an environmental enhancement plan (Animal Welfare Act, Section 3.81). Enrichment options described in the plan should be selected to demonstrably promote species-typical behaviors. Too often, enrichment choices...

Training time required to collect a variety of biological samples using primarily positive reinforcement training methods

Positive reinforcement training (PRT) methods can be applied to gain the voluntary cooperation of laboratory primates with the collection of biological samples. Information will be provided on training techniques used and the amount of training time required for various sample...

Efficient cooperative chair training

Traditional procedures for training nonhuman primates to be restrained in chairs typically involve very little use of positive reinforcement. In this talk, we detail a refined chair training procedure which uses a mix of positive and mild negative reinforcement to...

Effect of short-term pair housing of juvenile rhesus macaques (Macaca mulatta) on immunologic parameters

Social housing of nonhuman primates (NHP) in an infectious disease setting presents unique challenges, and individual housing is often scientifically justified. At our institute, we recognized an opportunity to limit individual housing to the minimal period necessary by pair-housing NHP...
