Effect of pair housing on operant behavior task performance by rhesus monkeys

In conclusion, pair-housing monkeys is feasible for studies involving operant behavior testing as a model for a variety of complex brain functions. However, housing condition may affect some test parameters, and this effect must be taken into consideration during experimental...

Use of a telemetry system to examine recovery of the cardiovascular system after excitement induced by handling stress in a conscious cynomolgus monkey (Macaca fascicularis)

The aim of this study was to determine the time required for the cardiovascular system of a conscious cynomolgus monkey, in which a telemetry had been implanted, to recover from excitement induced by handling stress. After monkey chair restraint and...

Obtaining blood samples from awake rhesus monkeys (Macaca mulatta)

The training procedure of four pair-housed adult males is described. For the past seven months all four monkeys have continued to cooperate for blood sampling via vascular access ports without ketamine sedation. ... The sampling procedure with ketamine sedation took...

Positive reinforcement training as a technique to alter nonhuman primate behavior: Quantitative assessments of effectiveness

Empirical analyses quantified the amount of time required to train group-housed rhesus monkeys to come up, station, target, and stay. Twenty-four of the 26 monkeys who were successfully trained to station also were reliably trained to touch their targets on...

Blood chemistry and hematology of mother reared compared with nursery reared M. nemestrina from 2-10 years of age.

Research on prenatal stress and differential rearing in nonhuman primates has also shown effects on immunological and other health indices at later ages. We studied potential links between early infant experience and later biochemical factors in mother-social and nursery-peer raised...

Working with rather than against macaques during blood collection

12 adult pair-housed female, 5 adult single-housed male and 10 adult pair-housed male rhesus macaques, and 6 adult pair-housed female stump-tailed macaques were trained to cooperate during in-homecage blood collection. The total number of training sessions per animal ranged from...

Legal loophole for subminimal floor area for caged macaques

The USDA regulations pertaining to the minimum space requirements of nonhuman primates and the fitting of elevated resting surfaces are contradictory. They implicitly condone the prevailing perch design that allows maximal usage of animal room space by stacking the cages...

Utilization of toy devices by rhesus macaques

Adding toys to foraging devices may be a way to make them more attractive to the animals. This seems to work particularly well when the toy devices are filled on a rotating basis.

Social display, feeding, exploration, and program attentiveness rates for rhesus monkeys (Macaca mulatta) exposed to audio-visual programs

Ten rhesus monkeys were separated from their social groups for medical treatments lasting 3-14 days. Animals required hospitalization for conditions including fight wounds, diarrhea, and surgery. To prevent boredom, reduce isolation stress, and discourage removal of sutures and surgical wraps,...

Self-injurious behavior in rhesus monkeys: New insights into its etiology, physiology, and treatment

Self-injurious behavior (SIB) is a significant human health problem frequently associated with profound intellectual disabilities, genetic diseases, and psychiatric conditions. However, it also occurs in subclinical populations and appears to be on the rise in adolescents and young adults. SIB...
