Zoo Nutrition Myth: A fruit is a fruit

Vitamin D metabolites 25(OH)D and 1,25(OH)2D and Kidney function indices and the relationship to diet in Goeldi’s monkeys (Callimico goeldii)

In Brookfield Zoo’s Goeldi’s monkey colony, a large number of deaths related to renal disease has been documented. Review of post-mortem results from Goeldi’s monkeys in the past 20 years revealed that in deaths of animals over 18 months of age, renal disease was a primary pathologic diagnosis. Although the nutrient requirements of Goeldi’s monkeys have not been described, these...

Exhibiting animals in large naturalistic exhibit: without prey or predator

Modern zoos are increasingly inclined to exhibit animals in more naturalistic surroundings, often in large mixed species exhibits, and the Biodôme de Montréal is no exception. The Biodôme is subdivided into four sections representing specific ecosystems. The First ecosystem, the tropical rainforest, represents Amazonia and all species of trees and animals are from South America. The Laurentian forest, the St....

Influence of diet transition on serum calcium and phosphorus in captive giraffe

Pathology in captive giraffe is relatively common and has often been attributed to nutritional causes. It was hypothesized that reducing dietary starch and phosphorus (P) would change serum mineral concentrations to be more in line with typical mammalian values. Captive giraffe (n=6, Henry Doorly Zoo, Omaha NE), previously fed a commercially available diet, were transitioned to a reduced starch diet...

The effect of fish analog diet on beluga whale (Delpinapterus leucas) health and body condition

In zoos and aquariums the staple diet for marine mammals is freshly thawed, previously frozen fish and squid. Feeding a variety of fish to captive piscivores can be a major challenge to institutions, due to cost and availability thereby making a readily available prepared fish analogbased diet very appealing. Past studies feeding the Mazuri® fish analog product (PMI IntI, St....

Feeding frenzy: turning the science of zoo nutrition into a game for kids

In 2012, Busch Gardens opened the Animal Care Center to the public to share general information about the techniques and science involved in preventative and emergency care of the 12,000 animal residents of the zoo as well as local injured wildlife. Zoo educators teamed up with the veterinary and nutrition staff to develop demonstrations and interpretive elements that would share...

Development of a rumen fluid preservation technique and application to an in vitro dry matter digestibility assay

The objective of this study was to develop a rumen-fluid freezing and thawing protocol to be used with a two-stage in vitro dry matter digestibility (IVDMD) assay. Rumen fluid was collected on three different days (one week apart) from a domestic steer (Bos taurus) and preserved via freezing, freezing with 5% glycerol (GLY) or freezing with 5% glycerol plus a...

Normal urinary mineral excretion levels in African elephants (Loxodonta africana)

Metabolic bone disease has occurred in several incidences of elephant neonates hand-reared on milk replacement formula. Monitoring for metabolic bone disease historically has been done through serum calcium and phosphorus concentrations. Serum concentrations are tightly regulated and changes in concentration are typically not evident until skeletal changes have already occurred. Urinary calcium and phosphorus excretion levels may provide earlier evidence...
