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...

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...

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.

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...

Environmental enrichment during separtion in captive common marmosets (Callithrix jacchus): Behavioural and physiological aspects

In the social condition, the animals tended to show an increased heart rate, presumably resulting from competion over access to the foraging device.

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...

Manipulating the affiliative interactions of group-housed rhesus macaques using positive reinforcement training techniques

Social housing, whether continuous, intermittent, or partial contact, typically provides many captive primates with opportunities to express affiliative behaviors, important components of the species-typical behavioral repertoire. Positive reinforcement training techniques have been successfully employed to shape many behaviors important for...

Lower-row caging in a two-tiered housing system does not affect the behaviour of young, singly housed rhesus macaques

It has been suggested that housing of laboratory primates in two-tiered racks adversely affects the psychological well-being of those primates housed on the lower row. Excessive darkness and its consequences are among the factors suggested to account for the supposed...

Self-biting in caged macaques: Cause, effect and treatment

In the United States, there are an estimated 15,000 individually caged macaques. If 10% of these animals exhibit visible injuries resulting from self-biting and another 10% show unnoticed self-biting behavior, then about 3,000 animals (20%) are affected by this gross...
