Abstract: Although environmental enhancement plans for nonhuman primates vary between facilities, feeding enrichment represents a component of most programs. As part of a facility's feeding enrichment program, offering hand-fed food items by trained staff provides an opportunity for positive human interaction. We hypothesized that increased implementation of such enrichment would be associated with increased likelihood of a monkey accepting a hand-fed treat from a stranger. Several species of monkeys were tested at the Tulane National Primate Research Center. In 2002 and 2005, we recorded the number of caged monkeys that accepted a treat tablet from an unfamiliar person within 10 s. We compared the frequency of caretaker-implemented feeding enrichment documented for each animal room during the month proceeding data collection with the proportion of animals within the room that accepted the treat from the stranger. In 2002, 29.8% of the 500 subjects accepted the treat from the unfamiliar person. The proportion of animals that accepted the treat was significantly correlated with the number of days during which feeding enrichment had been implemented. In 2005, feeding enrichment frequency had increased by 76%, and 53.4% of the 676 subjects accepted the treat. These findings suggest that this simple form of enrichment may improve monkeys' responses to unfamiliar people, and that it holds promise as a method for mediating the stress imposed by human activity in animal rooms. In addition, a stranger's treat-feeding attempts may be a useful indicator of an institution's implementation of their environmental enrichment program.

Abstract: An important component of nonhuman primate environmental enrichment programs is affording the animals the opportunity to manipulate objects. Although these objects and various bulky food items enrich the quality of life for nonhuman primates, they complicate the duties of facility maintenance personnel. A prime example of these sometimes costly complications is a seemingly never-ending series of floor drain obstructions. We devised a simple, inexpensive modified drain cover that prevents large items from entering the drain. The total cost of materials for this device was 1.12 dollars, and it required only 15 min of labor for assembly. The design and implementation of this modified drain cover illustrate why the interaction between physical-plant personnel and animal-care personnel is key to the operation of a successful animal care and use program and proper maintenance of laboratory animal facilities.

Abstract: The Division of Laboratory Animal Resources (DLAR) at the University of Pittsburgh proactively instituted a nonhuman enrichment plan that is founded on the United States Department of Agriculture (USDA) Final Report on the Environmental Enhancement to Promote the Psychological Well-being of Nonhuman Primates (July 1999). This document is a draft policy of the USDA that has not yet been enacted. In anticipation of the these standards becoming policy, the DLAR, and our Institutional Animal Care and Use Committee (IACUC), primate user groups, and Enrichment Specialist compared these new standards to our previous IACUC-approved plan. Our goal was to be "proactively compliant" to anticipated policy changes described in The Final Report. We established a program that was consistent with the five "critical" elements of The Final Report and our goal to have a revitalized enrichment plan that applied internal evaluation for continued improvement. A task force was implemented to review current literature and regulations on enrichment. Then a subcommittee consisting of veterinarians, investigators whose research would be affected by the anticipated policy changes, and IACUC members was formed. They established criteria for dispensation from plan elements, brought current protocols into compliance, shared enrichment and documentation techniques, and considered research methods in decision-making. In addition, a primate Enrichment Specialist position was developed and recruited. The Enrichment Specialist worked with investigators to evaluate enrichment and documentation needs and organized and implemented plan structure. The DLAR staff provided animal care and veterinary insight and reported to the IACUC. Investigators discussed how research and enrichment affected each other. The IACUC considered these issues before approving the plan. Our revitalized plan is running smoothly. The Enrichment Specialist oversees plan implementation and documentation. The DLAR assists enrichment and animal assessment. Investigators assist with assessment, provide enhanced enrichment, and document their progress. The IACUC addresses dispensation requests through designated review on the large-animal subcommittee.

Abstract: Investigators have an obligation to promote the psychological well-being of nonhuman primates used in research. Considerable emphasis has been placed on providing nonhuman primates with enriched environments as a means to achieve this objective. A framework is provided that consists of a set of hypotheses about well-being, and the extent to which exposure to various enrichment devices and procedures actually promotes well-being is evaluated. Two hypotheses are concerned with fostering species-typical behavior: use (versus nonuse) of the enrichment, and whether use of enrichment helps normalize other aspects of the behavioral repertoire. Two additional hypotheses are concerned with abnormal behavior: whether currently existing enrichment lowers levels of abnormal behavior, and whether it prevents the behavior. This framework is applied to various enrichment strategies ranging from toys and foraging devices to social interaction. Most devices are used by nonhuman primates and thus constitute an important way to enrich the captive environment. However, enrichment devices vary as to their effectiveness in normalizing the behavioral repertoire and eliminating abnormal behavior. Only social contact satisfies the goal of promoting a wide variety of species-typical activities while at the same time reducing or preventing the development of abnormal behavior.

Abstract: Both to meet the regulatory requirements of the Animal Welfare Act and the increasing body of evidence supporting that most species of nonhuman primates (NHP) should be group-housed whenever possible, modifications to nonhuman primate caging are described. Perches and cage-connecting tunnels were fabricated for existing macaque caging. These are semi-permanent, easily sanitizable, and allow for all cage functions to operate as designed. All NHP housed in these cages were part of experimental studies approved by the institutional animal care and use committee.

Abstract: Serendipity is discussed as a form of controlled chaos, a phenomenon in a class with synchronicity and other actions affecting research in terms of theory versus observation (e.g., "optional stopping"). Serendipity is a fundamental aspect of basic research, a profitable and normal outcome in the context of "informed observation." The serendipitous finding fits into the following pattern: it is unanticipated, anomalous, and strategic. All observations that have meaning must fit into some context in the observer's mind or suggest a revolutionary new context. It is critically important to maintain access to the resources provided by established primate centers and similar laboratories to capitalize in a timely way on serendipitous findings and to benefit from valuable discoveries made in more directly targeted development investments. Examples are given of serendipitous insights gained in experimentation and observation relative to nonhuman primate research, including both broad and narrow topics. Genomics, which uses comparison-based strategies and capitalizes on the DNA sequences of genetic information, presents what might seem the basis for endless serendipity because nonhuman primates are likely to share most genes present in the human genome. Other topics discussed include infant behavior, birth periodicity, leprosy, cystic fibrosis, environmental enrichment, endocrinology, drug development, and the rapidly expanding study of infectious diseases and pathogen-based bioterrorism.

Abstract: During the last two decades an increasing amount of attention has been paid to the housing and care of monkeys and apes in laboratories, as has been done with the housing and care of other categories of captive animals. The purpose of this review is to develop recommendations for adaptations of housing and care from our knowledge of the daily behavioural activity of monkeys and apes in natural conditions and in enriched laboratory conditions. This review deals mainly with adaptations of daily housing and care with respect to behaviour, and it is restricted to commonly-used species: Callitrichidae (Callitrix jacchus, Saguinus oedipus); Cebidae (Aotus trivirgatus, Saimiri sciureus, Cebus apella); Cercopithecidae (Macaca fascicularis, M. mulatta, M. nemestrina, M. arctoides, Chlorocebus aethiops, Papio hamadryas, P. cynocephalus); Pongidae (Pan troglodytes).

Abstract: There has been in recent years a substantial increase in the variety of enhancement devices available for nonhuman primates in captivity, and the task of properly outfitting a housing unit can be daunting. Researchers continue to investigate the specific impact and importance of environmental enrichment, but it is generally accepted that increasing the complexity of the environment for the mental and physical stimulation of nonhuman primates is beneficial to their health and contentment, and enrichment is now a standard component of primate husbandry.

Abstract: As contact with caretakers is likely to make up the majority of human-primate interactions in laboratories, caretakers represent an important influence in the lives of captive primates. The aim of this study was to determine how caretaker-primate relationships affected the behavior of primates in the laboratory. We examined whether stump-tailed macaques (Macaca arctoides) who were evaluated by caretakers as being either friendly or unfriendly differed in the quality and quantity of interactions with their caretakers during husbandry procedures and in their behavior at times of high and low levels of caretaker activity. Results revealed that animals who had friendly relationships with caretakers were less disturbed by routine husbandry procedures, approached caretakers more often, and were willing to accept food offered by caretakers compared with animals considered unfriendly toward their caretakers. The study concluded that the quality of the primate-caretaker relationship may have an important impact on behavior and may have implications for the well-being of animals and caretakers, as both can benefit from positive feedback from one another.
