Preliminary investigations into circulating vitamin E concentrations in captive okapi (Okapia johnstoni)

Normal circulating vitamin E levels have not been established for okapi (Okapi johnstoni) on a captive diet. Blood samples were obtained in 1996 by the Okapi SSP for free-ranging okapi in Zaire (Lukas, 1996). In 2009, vitamin E levels were acquired for animals housed at the Epulu Station in the Democratic Republic of the Congo fed an all leaf diet...

Does B vitamin supplementation increase survival or weight gain stranded California sea lions

When pinnipeds enter a rehabilitation facility, they have often fasted for an unknown period of time and are nutritionally deficient. They often are then fed dead fish. Certain species of fish are deficient in vitamin B1, or thiamine, as they contain thiaminases, enzymes which break down this vitamin after the fish have died. Deficiencies in these vitamins can result in...

Serum Magnesium and Zinc Status of Wild Ungulates in the Swaziland Lowveld

Serum magnesium (Mg) and zinc (Zn) were measured in 179 impala (Aepyceros melampus), 13 warthog (Phacochoerus aethiopicus), 6 kudu (Tragelaphu strepsiceros), 4 grey duiker (Sylvicapra grimmia) and 3 blue wildebeest (Connochaetes taurinus) from the Mlawula-Mbuluzi-Simunye Nature Reserve and Protected Area complex in the northeastern Swaziland lowveld from October 1985 to September 1986. Serum Mg was higher in the small concentrate...

Survey of circulating retinol (Vitamin A) and tocopheral (Vitamin E) concentrations in nesting marine turtles

Although marine turtles are relatively well-studied endangered and threatened species, critical discontinuities exist in the literature regarding numerous significant blood values, especially those of free-ranging populations. Gaining a better understanding of marine turtle ecological physiology is an urgent priority, considering the impact such information could have on conservation management plans and population health assessments [Bolten and Bjorndal, 1992; Raphael et...

Association of enterolith formation relative to water source pH consumed by wild equids under captive conditions

Intestinal disorders associated with enteroliths in domestic and wild equids have perpetuated folklore feeding practices in the western U.S. Enteroliths are stones formed in the large intestine, consisting primarily of magnesium ammonium phosphate [Mg(NH4)(PO4) – 6H20]. The frequency of enteroliths reported in clinical cases and necropsy reports among captive equids at the Zoological Society of San Diego appears to be...

Comparison of parathyroid hormone, calcium, phosphorus, and magnesium in serum and urine of nyala (Tragelaphus angassi) on concentrates or a forage only diet

The nyala (Tragelaphus angasii) herd at Busch Gardens Tampa has historically had one of the highest incidences of Johne’s disease (Mycobacterium avium paratuberculosis, Mptb) within the collection. A 10-yr epidemiologic review at Busch Gardens Tampa Bay revealed 27/83 (32.5%) Mptb culture positive individuals. At the time of this trial, 20/21 positive animals were also noted to be hypocalcemia. It was...

Nutritional physiology of duikers: a synthesis

Duikers (Cephalophus and Sylvicapra spp) form a guild of small antelope inhabiting the forests of sub-Saharan Africa. Local duiker communities are diverse, with 17 species ranging 10-fold in body mass (3 – 80 kg). Duikers can be adversely affected by forest management and hunting, thus 15 species are listed in the International Union for the Conservation of Nature red list...

Application of a Near Infrared Reflectance Spectroscopy (NIR) to measure protein, fat and moisture in fish samples

Quality control programs need methods for simple and rapid analysis of feeds and ingredients. Near Infrared Reflectance (NIR) and Transmission (NIT) Spectroscopy have been previously used for the analyses of fish carcasses (Gjerde and Mathias. 1987; Valdes et al.. 1989 and Downey. 1995). NIR was applied to measure percent fat, protein and moisture in fish samples used for food in...

Evaluation and Reformulation of Diets for Captive Aye-Aye (Daubentonia madagascariensis)

The feeding choices of wild aye-aye (Daubentonia madagascariensis) have been studied recently and found to include insects, insect larvae, nuts, bark, fungi, and fruits. Proximate analyses, some mineral, and some fat-soluble vitamin analyses of commonly consumed food items have been performed on these choices but there are no published data available which have quantified nutrient intake in captivity in relation...

Milk composition of the bongo antelope (Tragelaphus eurycerus) through lactation

Bongo antelopes (Tragelaphus eurycerus) are a species of antelope that originate from Africa. The gestation length is about 285 days. Bongo antelope calves weigh about 20 kg when born. Adult females weigh between 210-230 kg, while adult males weigh 240-270 kg. Young reach sexual maturity when approximately two years old. The milk samples used in this study were part of...

Evolution of a browse database- a global application

Browse – the new “buzzword” within zoological communities. Browse can include shrubs, trees, woody vines and stems, including various plant parts like berries and flowers. Browse is used for nutrient supplementation, behavioral enrichment and for some animal species it is life. Browse can also mean death to animals if a wrong plant or part is fed. With all of these...

METABOLIC CONSEQUENCES OF THE EARLY ONSET OF OBESITY IN COMMON MARMOSET MONKEYS.

We examined the patterns of fat mass gain from birth to 12 months in common marmosets (Callithrix jacchus), and tested the hypotheses that juvenile marmosets with excess adipose tissue will display higher fasting glucose, decreased insulin sensitivity, and decreased ability to clear glucose from the blood stream. Lean and fat mass was measured by quantitative magnetic resonance at 1, 2,...

Nutritional evaluation of a hand-rearing protocol for the San Clemente Island Loggerhead Shrike (Lanius ludovicianus mearnsi)

The San Clemente Island (SCI) Loggerhead Shrike, a subspecies found only on SCI, 80 km off the coast of San Diego, was federally listed as endangered in 1977. The wild population has numbered 12-18 birds for the last 10 years making this one of the most endangered birds in North America. As part of an ongoing, federally funded captive recovery...

A streamlined procedure for the determination of trace elements in foods

Considerable analytical challenges were imposed on food chemists when Congress passed the Nutrition Labeling and Education Act of 1990 (NLEA). When this law was ratified, labeling of fourteen food nutrients became mandatory, and thirty-four others voluntary. Many Association of Official Analytical Chemists (AOAC) validated methods for foods are matrix or analyte specific. Developing rugged, generic methodology for all foods became...

Possible Dietary Influence on Hepatobiliary Cancer in Sloth Bears (Melursus ursinus)

Compared with other bear species, sloth bears have an unusually high incidence of hepatobiliary neoplasms in captivity. Due to their highly specialized diet in the wild, there is a possibility that in captivity their diet may cause or promote hepatobiliary carcinogenesis and/or may lack certain food components which may inhibit carcinogenesis. A survey among zoos keeping sloth bears shows that...

Biochemical and physiological observations in meerkats (Suricata suricatta) at two zoos during dietary transition to a diet designed for insectivores

These studies assess the short-term and long-term effects of a commercially available manufactured diet (Mazuri® Insectivore, PMI Nutrition International, P.O. Box 66812, St. Louis, MO 63166-6812) intended for the feeding of insectivorous animals. The initial study evaluated palatability of the diet and the maintenance of health in captive meerkats over a 6-week period.

Metabolomics has great potential for clinical and nutritional care and research with exotic animals

This essay explores the potential of metabolomics for exotic animal research in a zoological setting. Metabolomics is a suite of analytical tools aimed at gaining a holistic understanding of animal metabolism without prior knowledge of the compounds to be measured. These metabolic fingerprints can be used to define normal metabolism for an unstudied species, to characterize the metabolic deviation of...

Comparative crop milk composition in grantivorous and frugivorous Columbidae

Crop milk, a glandular secretion produced by doves, pigeons, and some species of penguins and flamingoes, was collected from five different species of dove squabs at the Memphis Zoo between day 0 and 14 post-hatching. These species (Ptilinopus jambu, Ptilinopus magnificus, Gallicolumba luzonica, Gallicolumba rufigula, and Streptopelia decaocto), range from primarily frugivorous to primarily granivorous representatives of Columbidae. The samples...

A comparative study of blood lipids, electrolytes, and stress levels between captive and semi-captive orangutans (Pongo pygmaeus) under tropical conditions

Blood samples were collected from 27 orangutans (Pongo pygmaeus) (14 captive and 13 semicaptive) and were analyzed for triglycerides, total cholesterol, high density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDLC), sodium, potassium, chloride, calcium, phosphate, glucose, Cortisol levels, total white blood cells (WBC) and WBC differential count. There were significant differences (P<0.05) in total cholesterol and HDLC level between...

Dietary husbandry of captive white-tailed deer (Odocoileus virginianus) in the Northern USA and Canada must consider effects of daylength, age, and gender on tissue energy reserves

The effects of age, season, and gender on live body weights, lipogenesis and lipolysis in subcutaneous and perirenal adipose tissues, and weight and fat (ether extract) concentrations of skeletal muscles and viscera were studied in 48 captive white-tailed deer (Odocoileus virginianus) fed a complete diet ad libitum. Food intake, rates of lipogenesis, and accumulation of fat in skeletal muscle and...

Implementing “green business” practices at the Santa Barbara Zoo

The Santa Barbara Zoo has a long history of community involvement and paving the way for environmentally friendly practices in the Santa Barbara area. The Zoo initiated the first community recycling program more than 20 years ago. In 2007 The Zoo created an in house peer-committee “Sustainable Operations Committee (Green Team)” to review and establish responsible environmentally responsible practices. The...

Effect of Vitamin D3/ Ascorbic Acid Supplementation on Growth and Tibia Characteristics of Green Water Dragons (Physignathus cocincinus, Cuvier 1829)

A preliminary experiment was conducted to investigate the interactive effect of one level of a combined dose of vitamin D3/ascorbic acid (C) supplementation on growth performance and bone development in green water dragons (Physignathus cocincinus, Cuvier 1829) .Ten forty- seven day old female green water dragons obtained from one clutch of eggs were selected for this study. From birth to...

Effect of dietary nutrient level and source on feeder mouse nutrient composition

Whole prey items may contain lower nutrient levels than desired for feeding exotic carnivores. The purpose of this trial was to gather preliminary data on the effect of different dietary treatments on the nutrient composition of mice at various ages. Dietary enrichment with vitamin E and chelated minerals in general did not improve total body levels of most nutrients, but...

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...

Commentary- Skepticism and science: responsibilities of the comparative nutritionist

Comparative nutritionists are asked to formulate diets for over 3,000 species of animals,including mammals, birds, reptiles, amphibians, fish, and invertebrates. Little research has been conducted to provide an information base for this task, and both popular and scientific publications contain factual errors and irrational concepts that confuse the user. When data are suspect and theories do not make sense, they...

A summary of the role of The American Registry Professional Animal Scientists

The American Registry of Professional Animal Scientists (ARPAS) is a body that promotes the professionalism of its animal scientists members. Workers in several fields can apply to have their credentials and experience recognized by their peers. After 10 years of different embodiments and halting progress, ARPAS was launched in 1984, operating without a loss in any year since. Sustaining societies...

Food safety training for keepers in decentralized zoo kitchens

A food safety program was developed for training keepers in a decentralized zoo kitchen system. Instruction covered food safety standards of the state of Illinois; reviewed information regarding USDA and AZA food safety standards; and provided keepers with action-based steps they could take to prevent food safety concerns. In addition, lead keepers had separate sessions to ensure food safety standards...
