The Influence of Giraffe Behavior on Parasite Load: Impact of Husbandry Modifications at Busch Gardens Tampa Bay

Haemonchus contortus is a gastrointestinal parasite that lives in the abomasal mucosa of ruminants. Similar to cattle, giraffe housed in warm climates are prone to parasitism by stronglyes such as Haemonchus contortus. At Busch Gardens in Tampa, Florida a behavioral study and retrospective parasite survey was conducted to determine if a correlation exists between giraffe behavior, feeding methods, and parasite...

Birth weights and growth rates of giraffe and okapi at Disney’s Animal Kingdom

There is a lack of information available regarding the average birth weights and growth rates of many exotic animal species. This information can prove useful when evaluating the health of new born animals in a zoological setting. Within 24 to 48 hours of birth, giraffe (Giraffa camelopardis) and okapi (Okapia johnstoni) at Disney’s Animal Kingdom are weighed and health is...

Feeding behavior of a herd of Masai giraffe (Giraffa camelopardalis tippelskirchi) at the San Deigo Zoo

The objective of this study was to determine the feeding behavior of a herd of 2.5 Masai giraffe (Giraffa camelopardalis tippelskirchi) (Table 1) and compare this to feeding behavior in other zoo and free-ranging giraffe. In May 2020, 16 h of observations (0500 through 2100) were divided into four time periods (early morning, late morning, early afternoon, evening) and the...

Influence of diet on serum chemistry values in captive giraffe over four years

Over the past several years, herbivore diet formulations have transitioned toward lower starch and sugar and higher concentrations of structural carbohydrates such as neutral detergent fiber. Following the Giraffe Nutrition Workshop in 2005, recommendations were released that encouraged diets containing less than 5% starch and less than 0.5% phosphorus for captive giraffe. In December 2005, seven giraffe (Giraffa camelopardalis reticulata)...

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.

An update on giraffe (Giraffa camelopardalis) response to dietary fiber form and carbohydrate profile: implications for animal health

An experimental coarse browser supplement (EF) and a mixture of 75% Mazuri Browser Breeder and 25% Omelene 200 (GF) were used to evaluate the effects of dietary physical form and carbohydrate profile on six non-lactating adult female giraffe (Giraffa camelopardalis reticulata) in a modified reversal study using seven 21 day periods. Individually housed giraffe were fed ad libitum alfalfa hay,...

Serum fatty acids concentrations in free-ranging and captive giraffe (Giraffa Camelopardalis)

Serum concentrations of fatty acids in captive giraffes were compared to values obtained from free-ranging giraffes in an effort to identify potential nutritional differences in the captive population. Captive giraffes have a specific set of maladies, including peracute mortality, energy malnutrition, pancreatic disease, urolithiasis, hoof disease, and severe intestinal parasitism that may be nutritionally related. Serum samples from 20 captive...

The impact of nutritional factors on the development of phosphatic uroliths using meat goats as a model for captive giraffes

Obstructive urolithiasis is a documented problem in domestic ruminants, such as the meat goat, and exotic herbivores, such as captive giraffe. These two species develop phosphorus based uroliths and are considered browsing ruminants. Due to the logistical challenges of performing studies with captive giraffe, a metabolic trial was conducted using meat goats as a model. The intent of this study...

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...

Variation in voluntary intake of feeds by captive giraffe (Giraffa camelopardalis): Implications for meeting nutrient requirements

Data prompting evaluation of captive giraffe feed selection were obtained from a modified reversal study investigating the effects of dietary physical form and carbohydrate profile. Six non-lactating adult female giraffe (Giraffa camelopardalis reticulata) were used in seven 21-day periods. Supplements were: an experimental non-pelleted browser supplement (EF) and a mixture of 75% Mazuri Browser Breeder (PMI Nutrition International, LLC, Brentwood,...

Milk composition of the reticulated giraffe (Giraffa camelopardalis reticulata)

Reticulated giraffes (Giraffa camelopardalis reticulata) are the most common subspecies of giraffe maintained in zoological institutions. The gestation length for a reticulated giraffe is about 455 days (15 months). Lactation in wild giraffes has been estimated to last 12-13 months. The milk samples used in this study were part of the Smithsonian National Zoological Park’s Milk Repository and had been...
