The rhythmic relation between antler and bone porosity in Danish deer
Bone
|January 1, 1987
Summary
Danish Roe deer antlers and bones show an inverse relationship in porosity. Bone calcium is mobilized for antler growth, and decreasing antler porosity may cause shedding.
Area of Science:
- Zoology
- Veterinary Science
- Bone Physiology
Background:
- Annual physiological osteopenia affects mature male Roe deer.
- Antler growth requires significant calcium deposition.
Purpose of the Study:
- To investigate the relationship between antler and metacarpal bone porosity in Roe deer.
- To explore the role of bone calcium in antler mineralization.
- To understand the mechanism behind antler shedding.
Main Methods:
- Analysis of antler and metacarpal bone porosity in mature Danish male Roe deer.
- Statistical correlation analysis between bone and antler porosity.
- Observation of porosity changes throughout the antler cycle.
Main Results:
- A highly significant inverse correlation was found between antler and metacarpal bone porosity.
- Calcium mobilization from bones to antlers is indicated.
- Antler porosity significantly decreases towards the end of the antler period.
Conclusions:
- Bone porosity decreases as antler mineralization progresses, supporting calcium transfer.
- Reduced antler porosity is a potential cause for antler shedding in Roe deer.
