The Stroh symbol serves as the age indicator of the young hare. Young hares up to about 6 to 8 months of age have a thickening of the ulna above the wrist joint . After slightly buckling the paw in the joint , it can be felt through the fur . The thickening is the epiphyseal plate . This is where the length of the bone grows. The body growth of the brown hare is completed in about 9 months and the thickening disappears again.
This sign was named after its presumed discoverer G. Stroh, who published his findings in 1931 in the Tierärztliche Wochenschrift (12) under the title “Two safe age features in rabbits”. The French hunting literature suggests that this feature was already known to hunters in the Middle Ages, but was forgotten.
