A note on foetal growth and development of the giraffe Girafla camelopardalis girafla

The growth of the foetus of the southern giraffe is discussed. Gestation period is calculated as 457 days being the mean of 48 observations of other workers. Birthmass is taken as 102 kg from measurements on wild giraffe. This is almost twice as great as some published figures for captive giraffe. However, subspecies also differ. Foetal growth followed a typical “J” shaped curve when plotted from the mass of 24 foetuses. The increase in vertebral column length followed a straight

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
