Evaluating physiological and behavioural responses to social changes and construction in two zoo-housed female giraffes

Exposure to external repeated or long-term stressors can alter animal behaviour and physiology. At zoos, construction of new buildings and habitats is one potential unavoidable long-term stressor. During the construction of a new exhibit near the giraffe enclosure at Lincoln Park Zoo (Chicago, IL), the Zoo’s two female giraffes, Giraffa camelopardalis rothschildi and Giraffa reticulata, were monitored for changes in behavior and faecal glucocorticoid metabolite (FGM) levels during five phases of construction and enclosure access. The FGM analysis was validated

A Multi-Institutional Assessment of Factors Influencing Locomotion and Pacing in Captive Okapis (Okapia Jonhstoni)

The okapi (Okapia johnstoni), native to the Democratic Republic of Congo, is a large, solitary, and diurnal forest-dwelling ungulate highly sensitive to captive conditions. The captive population demonstrates persistent health problems, reproductive abnormalities, and several potentially abnormal repetitive behaviors. This study reports on locomotion and pacing in adult male and female okapis. Commonly, data on repetitive behavior have been derived from surveys. Although insightful, the results are often highly generalized and provide little information about the true preponderance and nature

Analysis of stereotypic behaviour and enhanced management in captive Northern Giraffe Giraffa camelopardalis housed at Zoological Garden Alipore, Kolkata

In the wild, giraffes live complex social lives exhibiting fission-fusion social systems. They have sophisticated communication which likely forms a crucial component regulating subgroup dynamics. They spend a large part of their day browsing and travelling over large distances. In captivity, lack of continuous browsing opportunities and limited space can lead to various abnormal and stereotypic behaviours. These stereotypic behaviours can have cascading detrimental health consequences. A behavioural analysis of stereotypic behaviours in giraffes under human care was conducted to

Scientific Approaches to Enrichment and Stereotypies in Zoo Animals: What’s Been Done and Where Should We Go Next?

The zoo scientific community was among the first to focus attention on captivity induced stereotypic behaviors, their causes, and methods of eradication. Environmental enrichment has emerged recently as the main husbandry tool for tackling this problem. An increasing number of research publications have attempted to evaluate the effectiveness of enrichment in reducing stereotypic behavior and to develop further concepts to explain how effective enrichment works. A review and meta-analysis of this literature indicates that enrichment is a successful technique for

Brief chapter summaries of ‘Stereotypic Animal Behaviour – Fundamentals and Applications for Welfare’ (2nd ed.)

Repetitive, abnormal behaviour patterns are performed by tens, perhaps hundreds, of millions of animals worldwide: animals that live on farms and in laboratory animal facilities, stables, kennels, zoos, even in our homes. Our introductory chapter reviews the extent of research into this ‘stereotypic behaviour’ – traditionally defined as ‘repetitive, unvarying, with no obvious goal or function’ – since the book’s first edition was published in 1993. We illustrate the growing number of papers on captive animals, contrasting them with the

The effect of increasing dietary fibre on feeding, rumination and oral stereotypies in captive giraffes (Giraffa Camelopardalis)

Many captive giraffes perform oral stereotypies, in particular tongue-playing, licking of objects (including conspecifics) and vacuum chewing. Typically, the diet of these large ruminants in captivity consists mostly of food concentrates, which are consumed rapidly and do not provide stimulation for their long, prehensile tongues. In the wild, browsing requires extensive use of this organ but in captivity material upon which to browse is limited. Consequently, vacuum activities, such as mock leaf-feeding behaviour, and stereotypies may develop. Rumination is also

The effects of increased hay-to-grain ratio on behavior, metabolic health measures, and fecal bacterial communities in four Masai giraffe (Giraffa camelopardalis tippelskirchi) at Cleveland Metroparks Zoo

We evaluated whether increasing the hay-to-grain ratio offered to Masai giraffe (Giraffa camelopardalis tippelskirchi) at Cleveland Metroparks Zoo would reduce oral stereotypies and alter feeding behaviors, maintain or increase serum calcium-to-phosphorus ratio, decrease serum insulin-to-glucose ratio and salivary insulin, and alter fecal bacterial community structure. Giraffe transitioned to a ∼90:10 hay-to-grain ratio in even increments over 8 weeks. A ration balancer was added during the seventh week of transition to ensure proper mineral and nutrient balance. We collected (1) behavioral

Developments to the Nutrition of Captive Giraffe (Giraffa camelopardalis)

The correct feeding of captive giraffe appears to be particularly problematic and traditionally, they have been termed as one of the most difficult ruminants to cater for (nutritionally) in the zoo. Recent research has demonstrated that some of the prevailing arguments underpinning dietary formulation to be incorrect. The most notable of these being the apparent need for elevated dietary protein and the provisioning of easily digestible carbohydrates (starches and sugars) that are thought to mimic the chemical composition of wild
