Serum concentration comparisons of amino acids, fatty acids, lipoproteins, vitamins A and E, and minerals between zoo and free-ranging giraffes (Giraffa camelopardalis)

Serum concentrations of amino acids, fatty acids, lipoproteins, vitamins A and E, and minerals in zoo giraffes (Giraffa camelopardalis) were compared to values obtained from free-ranging giraffes in an effort to identify potential nutritional differences in the zoo population. Zoo giraffes have a specific set of maladies that may be nutritionally related, including peracute mortality, energy malnutrition, pancreatic disease, urolithiasis, hoof disease, and severe intestinal parasitism. Dietary requirements for giraffes are not known; invasive studies used with domestic animals cannot

Redescription of Monodontella giraffae Yorke et Maplestone, 1926 (Nematoda, Ancylostomatidae) from a giraffe, Giraffa camelopardalis, from Zoo in China, with a discussion on the taxonomic status of Monodontella

Monodontella giraffae Yorke et Maplestone, 1926 was collected from the biliary duct of liver of a dead giraffe, Giraffa camelopardalis (Linnaeus) from the Tianjin Zoo, Tianjin, China. A redescription of this species was made using light microscopy and scanning electron microscopy (SEM). The lateral alae and the detailed structures of the spicules and genital cone were observed for the first time by SEM. The taxonomic status of the genus is discussed.

Failure of a Chemical Spray to Significantly Reduce Stereotypic Licking in a Captive Giraffe

The repetitive licking of nonfood substrates is a common stereotypic behavior in captive giraffes. In this study we attempted to reduce stereotypic licking in a Masai giraffe (Giraffa camelopardalis tippelskirchi) by applying a bitter chemical (marketed as a taste deterrent to prevent the unwanted licking and chewing of substrates) to the areas of the fence licked most frequently by the giraffe. We hypothesized that this treatment would reduce stereotypic licking. However, there were no significant overall changes in stereotypic licking

Feed Selection and Digestibility by Captive Giraffe

A digestion trial with subsequent examination of feed selection was conducted using two captive giraffe fed four feedstuffs. Apparent digestibility coefficients were relatively high, indicating that the animals were efficiently utilizing the feedstuffs. However, values could be affected by the possible ingestion of soil containing acid‐insoluble ash. A high fiber pelleted feed was eaten in a greater quantity than a low fiber feed, even though the constituents in each feed were the same. Gross energy content of residual hay was

Teaching young giraffe old tricks: Changing learned behaviors in a herd of captive giraffe

At Lion Country Safari (LCS) in Loxahatchee, FL, a sub-tropical climate and the adoption of unnatural behavior by the captive giraffe herd have collided to pose a threat to the health of the giraffe (Giraffa camelopardalis). In recent years, a resilient parasite known as Haemonchus contortus has become prevalent in the pastures where the giraffe are housed and has developed resistance to many standard de-worming drugs. H. contortus feeds on the host’s blood while residing in the abomasum of ruminants

Subspecific assessment of the North American captive giraffe population compared to extant giraffe populations across Africa

Approximately 25% of the North American captive giraffe population (n = 125) was compared to a large data set of wild-sampled giraffe from 28 national parks, refuges, and protected areas in Africa (n = 403).  The wild-sampled individuals are a part of a larger study being conducted by the International Giraffe Specialist Group (IGSG) towards the resolution of questions regarding the evolution, population genetics, ecology, behavior, census, and ranges of extant populations of giraffe throughout Sub-Saharan Africa.  The samples were

Social behaviour in captive reticulated giraffes (Giraffa camelopardalis reticulata): Analysis of enclosure use and social interactions between giraffes housed at Whipsnade Zoo

Wild giraffe (Giraffa camelopardalis) herds have been described as random associations of individuals, but recent research has suggested that giraffe do form social bonds and have a complex social structure. The aims of this investigation were to determine whether a group of three captive giraffe associated randomly or patterned their behaviour and proximity in a way that suggests social relationships. Also to analyse how the giraffe use their enclosure in order for the zoo to develop the enrichment program to

Quantitative Anatomy of the Trachea of the Giraffe (Giraffa camelopardalis rothschildi)

We described the macroscopic and quantitative anatomy of the trachea of the Giraffe (Giraffa camelopardalis rothschildi). The trachea of one juvenile male giraffe (25 months of age) weighing 754 kg was used in this study. The length of the neck was 125 cm. The trachea had 107 cm in length on its cervical part and 18 cm on its thoracic part. The total number of cartilage was 87.74 at the neck and 13 at the thorax. The general shape of
