A survey of the nutrient content and intake of the dry season diet consumed by captive Grand Cayman iguanas (Cyclura lewisi)

Nutrient concentrations were determined in foods consumed by both free ranging and captive Grand Cayman iguanas (Cyclura lewisi). Plant collection and nutrient intake was measured during the dry season, when mating is known to occur. Fourteen species of plants known to be consumed by free ranging iguanas, or thought to be historically consumed when their distribution was not limited, were...

So your director wants a farm in the zoo

It seems that humans have always craved animal contact. Even at a zoo, a place designed for wild animals, visitors want and even expect to be able to touch an animal. Petting corrals, touch tanks, feeding stations, etc. are the most popular exhibits at a zoo, especially for families with young children. Contact areas can provide a valuable educational experience...

Survey of nutrient concentrations in the diet, serum, and urine of giraffe maintained in North American zoos

In order to elucidate the causes of urolithiasis in giraffe, a comprehensive survey was initiated in September 2004 of giraffe within North American zoological institutions. Giraffe feeding practices and medical histories were examined, and holding institutions were recruited to submit samples of feeds, water, serum, urine and feces, and asked to participate in a feeding trial.

Medical considerations when exhibiting multiple taxa in large aquarium systems

Large multi-taxa aquatic systems are often challenging for both husbandry and veterinary personnel. A wide variety of diseases can afflict entire systems with potential medical considerations for all exposed taxa. Largely for logistic reasons, the most common method of disease treatment is the addition of chemotherapeutics directly to the aquatic environment. However, the potential for species-specific toxicoses associated with some...

Polar bears: aspects of handrearing

Zoos faced with the issue of handrearing polar bear cubs have found success with various formulas. Despite many common ingredients in zoos’ polar bear milk replacers, adjustments were made to accommodate specific medical or nutritional needs of the cub(s), and consequently there were differences in solids/energy offered and weaning age. Cubs from three institutions (San Francisco, Brookfield, and San Diego...

Nutritional and bacteriologic evaluation as part of a raw meat quality control program

Six lots of raw horsemeat diet (Zoo Carnivore Diet, Dallas Crown, Inc., Kaufman, TX 75142 USA) were analyzed in triplicate for selected nutritional and bacteriologic components. Aliquots of frozen meat were submitted to a commercial laboratory (Dairy One, Inc., Ithaca, NY 14850 USA) to determine proximate composition, mineral levels, and gross energy. Additional aliquots were thawed at 10°C for 44...

Cholesterol concentrations in free-ranging gorillas (Gorilla gorilla gorilla) and (Gorilla beringei) and Bornean orangutans (Pongo pygmaeus)

Cholesterol concentrations in captive gorillas and orangutans vary widely within species and average approximately 244 mg/dl for gorillas and 169 mg/dl for orangutans as previously published. The International Species Inventory System reports higher concentrations of 275 and 199 mg/dl for gorillas and orangutans, respectively. It is unknown if these values were typical and/or were influenced by captive management. To answer...

A retrospective study evaluating vitamin E supplementation in pelicans and plasma alpha-tocopherol concentrations in pelicans, storks, and flamingos

A retrospective study was conducted to evaluate the effectiveness of two vitamin E supplement forms in pink-backed pelicans (Pelecanus rufescens). The forms were a paste supplying 100 IU vitamin E daily or a capsule supplying 10.5 IU vitamin E daily. Baseline blood alpha-tocopherol concentrations were 7.15 ug/ml in 1998. After 10 months receiving vitamin E in the capsule form, the...
