Includes structural, behavioral, food, and auditory enrichment.
There is strong evidence that sensory experience in early life has a profound influence on the development of sensory circuits. Very little is known, however, about the role of experience in the early development of...
This column discusses the use of novel dietary supplements as environmental enrichment for rodents and rabbits. Items are commercially available from lab animal supply companies. The purpose of enrichment is to encourage behaviors that are...
At the California National Primate Research Center, one key to long-term success of macaque breeding colonies is to develop effective infant-rearing strategies that minimize the emergence of behavioral pathologies, which can be one indicator of...
The cotton rat (Sigmodon hispidus) presents a unique susceptibility towards human pathogens and is currently used in studies of human respiratory syncytial virus, adenovirus, and parainfluenza virus. Though valuable, this animal model has earned a...
The minipig is an increasingly popular species for use in behavioral and toxicologic studies. As a result, quantification of environmental enrichment preferences for this species is especially important. We exposed 6 individually housed prepubertal female...
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...
Comparative studies on neural plasticity in non-mammalian vertebrates are increasingly promoted as an important complement to mammalian models. In teleost fishes the number of brain cells increases with age, body weight, and body length throughout...
Stereotypic behaviours are common in animals in impoverished housing, arising from two complementary processes: (1) thwarted attempts to perform motivated behaviours; (2) forebrain dysfunction impeding normal behavioural inhibition. When enriched animals are moved to impoverished...
To do justice to the diverse approaches to enrichment and behavioral management around the world would entail a discussion beyond the limits of this publication. Therefore, guidelines and regulations in a representative sample of countries...
Positive reinforcement training is one component of behavioural management employed to improve psychological well-being. There has been regulatory promotion to compensate for restricted social housing in part by providing human interaction to singly caged primates...
