Summary: Occasionally, antlerless red deer stags, showing complete absence of antlers or possessing only antler knobs, can be observed. In the English literature, antlerless red deer stags are referred to as hummels. In this paper we present the case of a red deer hummel shot during the ruting season of 1981, in the area of Sokolovac, Croatia. The stag was aged at 5 years and weighed approximately 200 kg (undressed). The stag possessed only small pedicles and almost completely lacked antlers. Only small knobs of antler bone were present bilaterally. Furthermore, a discrepancy in height between left (length 17 mm) and right (length 35 mm) cranial outgrowth was observed. In the literature, the occurrence of antlerless red deer stags is mainly attributed to under- or malnutrition during the first year of life when pedicle development takes place, and a resulting underdevelopment of the pedicles. Because growth of antlers (at a normal rate) only starts after the pedicles have reached a critical size, insufficient growth of pedicles will result in a completely antlerless condition or, as in the present case, in the formation of only a very small amount of antler bone. However, also other factors could result in insufficient pedicle growth. As pedicle growth depends on androgenic stimulation, low levels of circulating androgens or a low density of androgen receptors in the antlerogenic periosteum could lead to poor pedicle growth and in consequence to a complete or almost complete lack of antler growth.
Key words: antler; incomplete development; pedicle; red deer hummel |
