Serum concentrations of amino acids, fatty acids, lipoproteins, vitamins A and E, and minerals in apparently healthy, free-ranging Southern Giraffe (Giraffa camelopardalis giraffe)

This pilot project began establishing a nutritional profile for free-ranging giraffe. The results will be used as a tool to begin assessing the nutritional status of captive giraffe. In October 2004 serum samples were collected opportunistically from seven adult and 17 sub-adult giraffe being anesthetized for different studies. Seventeen animals were from Double Drift Game Reserve and seven animals were from Kariega Private Game Reserve. The serum samples were analyzed for circulating concentrations of amino acids, fatty acids, lipoproteins, vitamins,

Seasonal changes in social networks of giraffes

Fission-fusion social societies allow animals to respond in a flexible manner to environmental changes by adapting the size and composition of a group. Although group members change frequently in these systems, associations with preferred partners may be found. In this study, we examined the grouping patterns of a population of 80 individual giraffes in a fenced South African game reserve over a 12-month period. Using social network analyses as a tool to evaluate observed associations, we subsequently analysed both sex-

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
