Under animal care situations that conform to compliance standards for environmental enrichment established by the Animal Welfare Act (AWA) and the Guide to the Care and Use of Laboratory Animals, at least 10% of laboratory...
Adding a few minutes of positive human interaction per animal per week to the management of captive gorillas resulted in improved well-being in several areas: the drop in abnormal behaviours, behaviours directed at the public...
Operant conditioning using positive reinforcement techniques has been used extensively in the management of nonhuman primates in both zoological and laboratory settings. This research project was intended to test the usefulness of counter-conditioning techniques in...
Of the potential flags of impaired well-being in laboratory primates, alopecia has received particular regulatory focus, making it a top priority for behavioral managers. Consensus on a reliable alopecia scoring system used by multiple facilities...
Positive reinforcement training (PRT) efficiency was examined as a function of training frequency in 33 pair- or triple-housed female rhesus macaques. The animals were trained three times a week, once a day or twice a...
Rhesus macaques housed indoors in captivity commonly display abnormal behaviors that are rarely seen in their wild counterparts. These behaviors include stereotypic behaviors and self-abuse. These behaviors are often seen as signs of poor welfare...
Bonobos are known for their pacifistic behavior and their large repertoire of behaviors that are thought to serve conflict resolution. One is an unusual form of ventro-ventral mounting that facilitates genital contacts (GC). Various hypotheses...
Advances in facility design, healthcare, and other strategies have produced an excellent quality of life for chimpanzees (Pan troglodytes) in biomedical research. Historically, many facilities housed chimpanzees individually or in small groups (2–3 animals). Laboratory...
PRT is a good way of shaping the behavior of captive animals and doing so can make the animals less stressed to promote their well being. PRT is commonly used by captive animal organizations in...
A small percentage of captive macaques spontaneously exhibit self-injurious behavior (SIB), mostly in the form of self-directed biting. Several risk factors have been identified in the etiology of SIB in monkeys, including exposure to early...
