Abstract:

The Common eland (Taurotragus oryx), a species of African spiral-horned antelopes, remains a popular game species, yet many aspects of its biology and behaviour remain unexplored. This research investigates the mother-calf bond in common elands, a crucial factor for calf survival and reproductive success. Despite its significance, this bond has received limited attention in research. Key factors influencing the mother-calf bond were examined, including age, weight, initiation, and termination dynamics of suckling, and affiliative social interactions. The study was conducted on captive common elands within a research facility. Data was collected through direct observations and video recordings. Data analysis was done by using IBM SPSS and generalized linear regression models. Results indicate that calf age negatively affects suckling duration, contrary to some previous findings. Calf weight is positively associated with nursing, likely due to increased nutritional needs. Initiation by the calf leads to more rigorous suckling, while social interactions such as licking, grooming, and head-butting impact suckling duration. Naso-anal contact (sniffing) before suckling contributes to mother-calf bonding and longer nursing sessions. This study enhances our understanding of common eland behaviour and provides insights for captive management and conservation efforts. By examining various factors influencing suckling behaviour, this research contributes to optimizing conditions for calf growth and development.
