The Use of Eye-Lens Weights for Aging Wild Rabbits, Oryctolagus cuniculus (L.), in Australia

Abstract

Eye-lens weight-age relationships were determined for rabbits from a wild population and from an enclosed population (of the same stock) in south-western Australia. Previously published curves of lens weight v. age for rabbits in eastern Australia are not entirely satisfactory models for the western Australian data. However, the differences, though obvious, are minor, and for general aging any of the published curves are adequate. For accurate aging, regional curves may have to be determined.
