Assessment of Food and Feeding Habit of Giraffe (Giraffa camelopardalis) in Sumu Wildlife Park of Ganjuwa Local Government Area of Bauchi State, Nigeria

The study assessed the food and feeding habit of giraffes in Sumu Wildlife Park of Ganjuwa Local Government Area of Bauchi State, Nigeria. The forage (woody plants) mostly preferred by the species and time used in consuming each food have not been ascertained despite the giraffe’s population in the study area hence, the need for this study which assessed the food and feeding habit of giraffe in the study area. The entire area was sub-divided into four (4) plots of

Use of Datura innoxia by ungulates in the Hoanib River, Namibia

The behaviour of springbok Antidorcas marsupialis feeding on the alien invasive plant Datura innoxia is described, as well as nervous symptoms possibly arising from tropane alkaloid poisoning. Dung collected from five herbivore species prior to 1989 contained no D. innoxia seeds, and other signs of use of it were rare. Feeding on this plant, principally by springbok and gemsbok, is currently limited to the vicinity of the Hoanib River floodplain. This is the first record of use of D. innoxia

Hypsodonty and tooth facet development in relation to diet and habitat in herbivorous ungulates: implications for understanding tooth wear

1. The evolution of high-crowned teeth or hypsodonty in herbivorous mammals is widely interpreted as a species specific adaptation to increasingly wear-inducing diets and environments at evolutionary time scales, with internal abrasives (such as phytoliths in grasses) and/or external abrasives (such as dust or grit) as putative causative factors. The mesowear score (MS) instead describes tooth wear experienced by individual animals during their lifetime. 2. Under the assumption that the abrasiveness that causes the MS in individuals is the same

Understanding selection for long necks in different taxa

There has been recent discussion about the evolutionary pressures underlying the long necks of extant giraffes and extinct sauropod dinosaurs. Here we summarise these debates and place them in a wider taxonomic context. We consider the evolution of long necks across a wide range of (both living and extinct) taxa and ask whether there has been a common selective factor or whether each case has a separate explanation. We conclude that in most cases long necks can be explained in

Nocturnal behavior in captive giraffe (Giraffa camelopardalis)—A pilot study

Captive giraffes (Giraffa camelopardalis) are known to perform oral and locomotor stereotypies. However, many studies do not consider the behavioral repertoire of these animals during the time when animals are confined to night quarters. At two zoological institutions, a total of six captive giraffes were observed via camera trap technology throughout six diurnal and nocturnal periods to record feeding, ruminating, and stereotypic behaviors. The effect of browse enrichment was assessed on alternate nights to determine how behaviors may be altered

Effects of dietary physical form and carbohydrate profile on captive giraffe

The effects of altering physical form and carbohydrate profile of giraffe diets were evaluated using six non-lactating adult female giraffe in a modified reversal study. Dietary treatments consisted of a supplement ration composed of commonly fed commercial concentrates (GF) and an experimental supplement (EF) containing greater concentrations of sugars and soluble fiber and lesser concentrations of starch than GF, as well as small, heavily lignified particles used to modify dietary fiber size and texture. Each study animal was housed individually

Giraffe husbandry and feeding practices in Europe results of an EEP survey

Problems of the locomotory system (like overgrown hooves, laminitis or joint problems) have been reported from the EEP giraffe population. To evaluate relevant husbandry practices and frequency of the problem, a survey was done covering EEP institutions (response to the questionnaire from 70 institutions representing 74 individually managed groups). 40 of the 74 groups reported that cases of problems of the locomotory system had occurred in their animals. Animals older than 8 years seemed to have a higher probability to

Feeding behaviour of giraffe Giraffa camelopardalis in the Willem Pretorius Game Reserve, Orange Free State

The habitat and feeding behaviour of giraffe in the Willem Pretorius Game Reserve, Orange Free State, are described. Acacia karroo, the single most important component, together with Asparagus laricinus, Rhus undulata and Ziziphus mucronata, comprises almost 90% of the giraffe’s diet. During the wet season deciduous plants of the savanna flats are preferred, but in the dry season the animals concentrate on evergreen plants in the more densely vegetated kopjies. Seasonal variation with respect to the number of plant species

Daytime activity patterns of gerenuk and giraffe in Tsavo National Park, Kenya

Individual daytime activity patterns of gerenuks (Litocranius walleri) and giraffes (Giraffa camelopardalis) varied considerably, being influenced by such factors as the social environment, reproductive status, predators, and weather conditions. In male gerenuks and female giraffes, relative feeding time per day was inversely correlated with ambient temperature at 14.00 hours; the same relationship applied to mean distance moved per hour by female giraffes. Gerenuks commonly lay down during rain; this probably serves to reduce heat loss. Most individual daily activity patterns
