The Activity Budgets of Captive Javan Gibbons (<i>Hylobates moloch</i>) and their Response to Visitor Presence or Absence
… stress can negatively impact the health of captive animals. Visitors may be a source of stress to captive animals in zoos and sanctuaries. Javan gibbons (<em>Hylobates moloch</em>) are endangered, and healthy captive populations are important to the species’ conservation. The purpose of this …

An attempt to advance seasonal reproductive activity in stoats (Mustela erminea) by use of an artifical photoperiod: A dissertation submitted in partial fulfilment of the requirements of the Degree of Bachelor of Science with Honours at Lincoln University
… is a requirement for year-round breeding in captive animals. This study tested the hypothesis that a long-day photoperiod applied to stoats during winter months would stimulate reproduction in these animals. Adult stoats (12 males and 12 females) were captured from the wild during summer and …

The effect of ketamine on stereotypic behavior in pregnant crated sows
Stereotypic behaviors expressed by captive animals are assumed to be abnormal and are believed to be a symptom of inadequate welfare. Common stereotypies of pregnant sows housed in gestation crates include the oral/nasal/facial (ONF) behaviors of rooting, bar-biting, and vacuum chewing. One …

Digestibility of Common Forage Plants and Energetic Requirements of the Black-Tailed Prairie Dog
… The higher AE in the wild population than in captive animals fed grasses is due to the presence of highly digestible forbs. The estimated Resting Metabolic Rate (RMR) of 0.056 kcal · g-1 day-l is relatively low; 85 percent of the Basal Metabolic Rate as predicted by a metabolic body size …

Competition Between Fox (Sciurus Niger) and Gray (S. Carolinensis) Squirrels (Illinois, Habitat Selection, Behavior)
… these two sympatric species were evaluated using captive animals. The presence of mange and an index of internal parasite loads were used to evaluate the effects of parasites on natural squirrel populations. The results of a multivariate analysis of habitat selection suggested that neither species …

Using feeding ecology to influence captive Slow Loris (Nycticebus spp.) nutrition and husbandry
… field, specifically production and domestic animals, exotic animal nutrition is very little studied. Some species are so understudied or shrouded in routine and anecdotes that both zoos and rescue centres manage them the same way, the wrong way. The slow lorises Nycticebus spp. are one of …

The ecology of venom use in the Javan Slow Loris (Nycticebus Javanicus) and its implications for conservation
… remains and parasites, and regularly checked animals for ectoparasites. I also captured arthropods over five months. I monitored the coexistence with potential predator species using camera traps and by conducting forest surveys throughout Java. Venom may be sequestered from secondary plant …

Solitary, reproductive, and parental behavior of maned wolves (Chrysocyon brachyurus)
… to preserve the species in the wild and through captive breeding programs have been hampered by a lack of information on its natural history. The maned wolf is a member of the family Canidae, which is known for extensive paternal care. Thus, the maned wolf is an interesting species for studying …

Engaging in effectiveness: the role of challenge in well-being and welfare
… have been investigating this question in captive animals for nearly half a century. It has also attracted the attention of academics in other fields because this line of inquiry may improve how we not only manage animals in our care but also think about our own well-being. Concurrently, …

The Social Behavior of Rehabilitated Spider Monkeys (<i>Ateles geoffroyi</i>)
<p>The welfare of captive primates in laboratories, sanctuaries, and zoos is affected by various aspects of their environments. Although space restrictions increase aggression and stress-related behaviors in most captive animals, primates show diverse mechanisms for displacing stress and mitigating …

Fitness for the Ark : are zoo bred amphibians ready to go back to the wild?
… endangered species through the reintroduction of captive-bred animals into the wild. Reintroduction is becoming a high-profile management tool for many threatened species, but it is unknown how many generations of captive breeding can influence a species’ physical and behavioural characteristics. …

Functional analysis and elimination of SIB in an olive baboon (Papio hamadryas anubis).
… been reported to occur in approximately 10% of captive, individually housed primates (Novak, Kinsely, Jorgensen, and Hazen, 1998). Accounts of the causes of SIB range from environmental to physiological. However, to date, no researchers have investigated the possible influence of social …
