Abstract
The relationship between lens weights and age was determined using 322 farm minks of known age. Twenty-seven of these animals were used in the histological study of the mandibular bone, the femoral diaphysis, the cementum and dentine of M1 and the canine tooth. The weight of the lenses represents a good age indicator until 1.5 years. In older animals counting the resting or adhesive line (L.A.C., ligne d'arrêt de croissance) of the acellular cementum in the region of the M1 constitutes the best criterion for determining the individual age. The period of L.A.C. deposition is indicated more accurately.
