Foot pressure distribution in White Rhinoceroses (Ceratotherium simum) during walking

Area of Science:

• Veterinary Science
• Biomechanics
• Zoology

Background:

• White rhinoceroses (Ceratotherium simum) are large ungulates facing foot diseases in captivity.
• Understanding locomotor biomechanics is crucial for managing foot health in these animals.
• Limited in vivo data exists on rhinoceros foot pressures during locomotion.

Purpose of the Study:

• To characterize peak pressures and center of pressure trajectories in white rhinoceroses during walking.
• To investigate if peak pressures are lowest around the fat pad, similar to elephants.
• To determine if peak pressures correlate with areas of high pathology incidence.

Main Methods:

• In vivo measurement of foot pressures and center of pressure trajectories during walking in white rhinoceroses.
• Analysis of pressure distribution across the foot, including the fat pad and digits.
• Descriptive analysis of locomotion patterns.

Main Results:

• Reduced peak pressures were observed around the fat pad and its lobes.
• Pressures were evenly and gradually distributed across all digits.
• Locomotion involved a more horizontal foot roll-off during the stance phase.

Conclusions:

• The findings suggest potential protective mechanisms of the fat pad and a gait adapted for even pressure distribution.
• This data provides a foundation for future research into rhinoceros locomotion and foot health.
• Impetus for improved care strategies for captive and managed rhinoceros populations is provided.
