The behaviour and dietary preferences of southern giraffe (giraffa camelopardalis giraffa) on the umphafa private nature reserve, kwa-zulu natal
The giraffe (Giraffa camelopardalis) has been severely neglected among the scientific community in terms of research. This investigation explores their behavioural patterns with focus on feeding behaviours and dietary preferences under influencing factors, which provides vital information for conservation in situ and population management ex situ. The behaviour and dietary composition of nine Southern Giraffe […]
Preliminary Report on Forage Availability and Resource Use by Reticulated Giraffe at Mugie Conservancy, Laikipia, Kenya
Main Findings To compare resource availability and animal diets, we conducted vegetation surveys and collected giraffe dung samples for diet analyses on the east and west sides of primary road C77 at Mugie Conservancy. The availability of tree resources differed on the east versus west sides of C77, where the more abundant species that we […]
Ancestral feeding state of ruminants reconsidered: earliest grazing adaptation claims a mixed condition for Cervidae
Background: Specialised leaf-eating is almost universally regarded as the ancestral state of all ruminants, yet little evidence can be cited in support of this assumption, apart from the fact that all early ruminants had low crowned cheek teeth. Instead, recent years have seen the emergence evidence contradicting the conventional view that low tooth crowns always […]
Higher masseter muscle mass in grazing than in browsing ruminants.
Using cranioskeletal measurements, several studies have generated evidence that grazing ruminants have a more pronounced mastication apparatus, in terms of muscle insertion areas and protuberances, than browsing ruminants, with the resulting hypothesis that grazers should have larger, heavier chewing muscles than browsers. However, the only investigation of this so far [Axmacher and Hofmann (J Zool […]
Growth, husbandry, and diets of five successfully hand-reared orphaned giraffe calves (giraffa camelopardalis rothschildi and giraffa camelopardalis reticulata)
Giraffe in the wild are in ongoing decline because of poaching and habitat loss and fragmentation, and were recently assessed as ‘‘vulnerable’’ on the IUCN (International Union for Conservation of Nature) Red List of Threatened Species. Captive breeding and saving each individual are therefore becoming more important to save this species from extinction. This paper […]
The effects of increased hay-grain ratio on masai giraffe behavior, health indicators and fecal microflora diversity
We hypothesized that switching to a diet that provides a higher hay-to-grain ratio offered to four Masai giraffe (Giraffa camelopardalis tippelskirchi) at the Cleveland Metroparks Zoo would reduce oral stereotypies and increase time spent performing feeding behaviors, maintain or increase serum calcium-to-phosphorus ratio, decrease serum insulin-to-glucose ratio, and alter fecal microbiome community structure. The diet […]
Seasonal and post-freezing variation of crude protein content and digestibility of willow and cottonwood leaves in regard to giraffe nutrition
The nutrient content of giraffe diets has not been well established. Many diets are lacking or have excessive amounts of protein, and protein is a good indicator of overall nutrient content. Hay and alfalfa are not ideal food items, and browse or leaves are the natural food choice for wild giraffe. In climates that experience […]
Influence of ration composition on nutritive and digestive variables in captive giraffes (Giraffa camelopardalis) indicating the appropriateness of feeding practice
The nutrition of captive giraffe (Giraffa camelopardalis), a browsing ruminant, is challenging because browse availability is limited in zoos and rations need to be composed of compensatory feeds. In this study, ration composition for giraffes in 12 German zoos was documented and linked to animal variables that indicate suitability of nutrition. Rations differed in proportion […]
The effects of increased hay-to-grain ratio on behavior, metabolic health measures, and fecal bacterial communities in four Masai giraffe (Giraffa camelopardalis tippelskirchi) at Cleveland Metroparks Zoo
We evaluated whether increasing the hay-to-grain ratio offered to Masai giraffe (Giraffa camelopardalis tippelskirchi) at Cleveland Metroparks Zoo would reduce oral stereotypies and alter feeding behaviors, maintain or increase serum calcium-to-phosphorus ratio, decrease serum insulin-to-glucose ratio and salivary insulin, and alter fecal bacterial community structure. Giraffe transitioned to a ∼90:10 hay-to-grain ratio in even increments […]
Social and demographic influences on the feeding ecology of giraffe in the Luangwa Valley, Zambia: 1973–2014
Body size influences metabolic rate, which impacts feeding ecology. Body mass differs by sex in size-dimorphic species, such as giraffes, and also by age. Giraffes reside in a fission–fusion social system, which influences feeding ecology due to frequent changes in group size and composition. We analysed 40 years of feeding records collected from a population […]
