Preference for Heights of Feeding Troughs in Mares: A Pilot Study

Preferences for the height of feeding troughs of seven mares were evaluated and, as awareness of surroundings when feeding is adaptive for horses, the relationship between preference responses and attention behaviours was also assessed. First, feeding troughs at four heights (0, 25, 50, and 75 cm) were provided for 16 days, and the amount of […]

Activity budgets and the relationship between feeding and stereotypic behaviors in Asian elephants (Elephas maximus) in a Zoo

Activity budgets were studied in eight Asian elephants (Elephas maximus) at Chester Zoo (UK) for 35 days, between January and November 1999. Recordings were made between 10:00 and 16:00 hr (with most behavior frequencies calculated between 10:00 and 14:00 hr). The elephants exhibited variation in activity depending on their age, sex, the time of day […]

Giraffe husbandry and feeding practices in Europe: Results of an EEP survey

Problems of the locomotory system (like overgrown hooves, laminitis or joint problems) have been reported from the EEP giraffe population. To evaluate relevant husbandry practices and frequency of the problem, a survey was done covering EEP institutions (response to the questionnaire from 70 institutions representing 74 individually managed groups). 40 of the 74 groups reported […]

Short-term benefits of play behavior and conflict prevention in Pan paniscus

Most theories on the function of play have focused on ultimate rather than proximate benefits. Play peaks during juvenility but, in some species, it is present in adulthood as well. In primates, social play and grooming often show a matched pattern because they bring individuals into close contact and favor social cohesion. In Pan, researchers […]

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 […]

Diet composition, food intake, body condition, and fecal consistency in captive tapirs (Tapirus spp.) in UK collections

Abstract 10.1002/zoo.20225.abs Intake measurements were carried out in 22 tapirs from seven UK zoological collections. Dry matter intake (DMI) ranged from 48 to 86 g/kg0.75/d. Across collections, the highest proportion of the ingested diet consisted of pelleted feeds (including grains and bread) at 46±17% DMI, followed by commercial produce at 26±12% DMI, roughage (excluding browse) at […]

Response of hatchling Komodo Dragons (Varanus komodoensis) at Denver Zoo to visual and chemical cues arising from prey

Abstract 10.1002/zoo.20219.abs Five hatchling Komodo Dragons (Varanus komodoensis) at Denver Zoo were observed in two experiments that studied the effects of visual and chemical cues arising from prey. Rate of tongue flicking was recorded in Experiment 1, and amount of time the lizards spent interacting with stimuli was recorded in Experiment 2. Our hypothesis was […]

Comparative digestion studies in wild suids at Rotterdam Zoo

Abstract 10.1002/zoo.20191.abs Among the artiodactyla, the suids are a group whose digestive physiology has hardly been investigated. The apparent digestibilities (aD) of macronutrients were measured in captive specimens of warthog (Phacochoerus africanus), red river hog (Potamochoerus porcus), and Visayan warty pigs (Sus cebifrons), and compared with those reported for babirusa (Babyrousa babyrussa) from the same […]
