Training pair-housed rhesus males to cooperate during blood collection

In many laboratory studies, venipuncture (blood collection) is a routine activity. Some animal care managers assume that blood collection requires single-housing and squeezing (and stressing) the primate subjects. Not true!Here, we show a simple training procedure that is based on...

Utilization of training techniques to minimize distress and facilitate the treatment of a chronically ill macaque

In order to permit the more frequent measurement of blood glucose, at times up to eight measurements a day, with minimal or no distress to the animal, we trained the monkey [long-tailed macaque with unspecified gender] to voluntarily present the...

The impossible housing and handling conditions of monkeys in research laboratories

The prevailing housing and handling conditions of monkeys in research institutions is described. The present situation in primate research laboratories strongly suggests that professional judgment is no guarantee that the inhumane housing and handling conditions of laboratory monkeys will ever...

Long-term proximity relationships in a captive social group of western lowland gorillas (Gorilla gorilla gorilla)

To visualize long-term social relationships among 12 gorillas in a captive breeding group at the San Diego Wild Animal Park, San Diego, CA, the multidimensional scaling (MDS) procedure was applied to proximity (within 5 m) values collected in five different...

Effective feeding enrichment for caged and pen-housed macaques at no cost

Using already existing structures of the cage, food puzzles can readily be 'constructed' to entice the animals to work for the retrieval of their daily rations of monkey chow.There are two options of 'constructing' such puzzles.

Psychological Well-Being of Laboratory Primates at Oregon Regional Primate Research Center

I was exposed to no protocols that required social isolation during my visit to the ORPRC. Rather, investigators were not giving priority to the social needs of the monkeys. For example, monkeys in virus studies at other institutions are housed...

Ideas of improving living conditions of non-human primates by improving cage design

Refinement in cage design are described that improve personnelsafety and routine husbandry procedures. It is difficult to observe animals in the bottom cages due to insufficient lighting. Flashlights can increase visualization in this situation. New cage specifications are designed to...

Successful formation of a large chimpanzee group out of two preexisting subgroups

Nineteen chimpanzees from preexisting subgroups were introduced into a social group [two adult males, six adult females along with six dependent infants, and five unrelated juveniles, four of whom had been hand-raised in a nursery unit]. ... The introduction process...

Paper 4: Welfare considerations in the use of marmosets and macaques for scientific research and testing: A comparison

Basic housing needs are outlined. Cages should be high enough to allow the animal to flee upward, preferably above human eye level. Marmosets do not like being caught, handled or restrained. They can be trained (by giving food rewards) to...

Seasonal and daily variation in stereotypic behavior in two species of zoo-housed lemur

Stereotypic behavior increased across time of day and was higher during the breeding season than any other time of year. It was not correlated with the number of zoo visitors.
