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 The arguments used during these controversial discussions have often been based on outdated facts.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 […]

Zoo Animal Feeding: A Natural History Viewpoint

In order to formulate animal feeding programs, zoos traditionally borrow knowledge and techniques, developed for domesticated animals, from livestock industry. Although livestock industry provides some of the basic components of feeding it is aimed at economic gain from animals, and the number of species it covers is extremely small. Moreover, wild animals are forced to […]

Formulating Diets for Tamandua (T. tetradactyla) in Brazilian Zoos

Diet has long been suspected to be the primary cause of Tamanduas inability to thrive in some Brazilian zoos. It is known that free ranging animals consume diets consisting of termites and ants. Unfortunately, little is known about the nutrient requirements of insectivorous species. In addition, incomplete data exist on the nutrient content of many […]

Effects of Dietary Physical Form and Carbohydrate Profile on Captive Giraffe

The effects of altering physical form and carbohydrate profile of giraffe diets were evaluated using six non-lactating adult female giraffe in a modified reversal study. Dietary treatments consisted of a supplement ration composed of commonly fed commercial concentrates (GF) and an experimental supplement (EF) containing greater concentrations of sugars and soluble fiber and lesser concentrations […]

Seasonal shifts in giant panda feeding behavior: relationships to bamboo plant part consumption

Abstract The giant panda (Ailuropoda melanoleuca) is classified as a carnivore, yet subsists on a diet comprised almost exclusively of bamboo. Wild and captive giant pandas use highly selective foraging behaviors for processing and consuming bamboo. These behaviors are for the first time quantified in captive giant pandas over a 5-year period of time showing […]

Effect of tannic acid on iron absorption in straw-colored fruit bats (Eidolon helvum)

Abstract 10.1002/zoo.20258.abs Excessive absorption and subsequent storage of dietary iron has been found in a variety of captively held birds and mammals, including fruit bats. It is thought that feeding a diet that is low in iron can prevent the onset of this disease; however, manufacturing a diet with commonly available foodstuffs that contains a […]
