Improving the efficiency of positive reinforcement training by testing food item preference

Positive reinforcement training relies on identifying an effective reinforcing consequence, often food, to be presented contingent on the performance of the desired behavior. Prior to training sessions, we used a multiple stimulus without replacement (MSWO) preference test to identify the...

Preventing boredom in NHPs using fleece fabric and food treats

Recently, I devised yet another way to use this fleece material to enhance the environments of our animals. To this end, I sought out a way to present food enrichment to our animals so that they would have to solve...

A European Union-compliant housing environment for nonhuman primates in a toxicology laboratory

As a global company, our institution made the decision to install European Union (EU) Appendix A-compliant nonhuman primate cages at one of its facilities. This investment represented a substantial evolution of standards commonly employed within a North American contract research...

Effects of caging on bone metabolism in cynomolgus monkeys (Macaca mulatta)

Juvenile cynomolgus monkeys are frequently used in drug pharmacokinetic and toxicology testing where they are cage housed for extendeded periods of time. In this study measures of body mass, bone metabolism, and turn over were compared between 2 groups of...

Laser lixit training: An alternative form of target training that can be utilized in the daily husbandry care of rhesus macaques (Macaca mulatta) and cynomolgus macaques (Macaca fascicularis)

Rhesus and cynomolgus macaques are some of the most frequently utilized laboratory nonhuman primates, and it is common for one facility to have a significantly large colony of either or both species. Daily care needs to be efficient and effective,...

Operant training differences between male and female group-housed nonhuman primates

Operant training of animals is a widely accepted practice for training or conditioning animals to cooperate with technical procedures or perform certain tasks in a laboratory setting. This type of training has been proven to reduce stress on the animal...

A novel approach for utilizing large group-housing style cages for nonhuman primates in toxicology studies

The ability to provide permanent group-housed caging for nonhuman primates involved in toxicology research is quickly becoming an important step in improving the overall quality of life for these animals. This type of caging offers increased vertical space allowing animals...

Factors affecting aggression among females in captive groups of rhesus macaques (Macaca mulatta)

Captive groups of primates often exhibit higher rates of aggression than wild, free-ranging groups. It is important to determine which factors influence aggression in captivity because aggression, particularly intense aggression, can be harmful to animal health and well-being. In this...

Behavior of female pairs vary between protected contact and full contact pair housing in rhesus macaques but not longtailed macaques

However, tactile contact can also be provided by means of barred or perforated panels that permit physical interaction but prevent entry into pair-mates' cages. Behavioral outcomesmay differ between these housing configurations and between species. To explore the interaction between these...

Separating cage-mates temporarily ? A LAREF discussion

The question was asked: “Research protocols sometimes require that compatible macaque pairs be physically separated for a limited time period (e.g., controlled food-intake studies; sample collection from chair-restrained subjects). Obviously – and as documented in the literature – partner separation...
