Assessment of Feeding Behavior of the Zoo-Housed Lesser Anteater (Tamandua tetradactyla) and Nutritional Values of Natural Prey
Very little information is available to zoo managers on the nutritional preferences of the lesser anteater, a highly specialized predator. By studying lesser anteater feeding behavior, we expect to contribute to improved management decisions and individual welfare experiences. We studied the response of zoo-housed lesser anteaters (n = 7) to feeders with live ants (Acromyrmex […]
Investigating the Effect of Disturbance on Prey Consumption in Captive Congo Caecilians Herpele squalostoma
Maintaining Gymnophiona in captivity provides opportunities to study the behaviour and life-history of this poorly known Order, and to investigate and provide species-appropriate welfare guidelines, which are currently lacking. This study focuses on the terrestrial caecilian Herpele squalostoma to investigate its sensitivity to disturbances associated with routine husbandry needed for monitoring and maintaining adequate wellbeing […]
Increasing browse and social complexity can improve zoo elephant welfare
While recent work has assessed how environmental and managerial changes influence elephant welfare across multiple zoos, few studies have addressed the effects of management changes within a single institution. In this paper, we examine how management changes related to social structure and diet affect the behavior of a group of zoo elephants over a 23‐month […]
Impacts of dietary modifications on the behaviour of captive western lowland gorillas (Gorilla gorilla gorilla)
Behavioural profiles of captive and wild Gorilla gorilla gorilla have been shown to differ greatly, with captive gorillas moving and foraging much less than their wild counterparts and often experiencing high levels of obesity and cardiovascular disease. Captive gorillas are typically fed an energy dense diet and housed in relatively small enclosures compared to wild […]
An investigation into keeper opinions of great ape diets and abnormal behaviour
Zoos are evidencing a shift in great ape diets to cultivated fruit-free to achieve a more wild-type nutritional composition (lower sugar, higher fibre). This study aimed to ascertain great ape keeper knowledge and opinions on the removal of cultivated fruit from great ape diets, to investigate feeding regimes currently in use and to understand the […]
Nutrition and husbandry conditions of Palearctic tortoises (Testudo spp.) in captivity
Mediterranean and Russian tortoises (Testudo spp.) are popular companion animals (pets), despite ongoing controversy concerning privately keeping reptiles. The arguments used during these controversial discussions have often been based on outdated facts. Therefore, a survey was developed to evaluate the current population structure, husbandry conditions, diet regime, and health status of Testudo species in captivity. […]
Growth rates of juvenile Boa constrictor under two feeding regimes
Many husbandry routines in zoo herpetology are based on tradition, authoritarianism, anecdote, or speculation. However, relatively few empirical studies underlie many very common practices. We compared growth rates among littermates of Boa constrictor raised under two feeding regimes that were identical in terms of the mass of food ingested, but differed in weekly versus bi-weekly […]
Dietary-induced modulation of the hindgut microbiota is related to behavioral responses during stressful events in horses
The bidirectional communication between the central and the enteric nervous system named the gut-brain axis has been widely recognized. The gut microbiota has been implicated in a variety of stress-related conditions including anxiety, depression and irritable bowel syndrome based on rodent studies or correlative analysis in human patients. The aim of the present study was […]

Western gorilla diet: A synthesis from six sites
The objective of this paper is to collate information on western gorilla diet from six study sites throughout much of their current range, including preliminary information from two sites (Afi and Lossi), where studies of diet have begun only recently. Food lists were available from each site, derived from indirect signs of gorilla feeding (such […]
