We have also shown that dry antler material has a lower impact energy absorption than that of wet antler, a property which, in a fight, is probably very important in the first clashing of antlers. However, dry antler has a much higher(More)
Ungulates select diets with high energy, protein, and sodium contents. However, it is scarcely known the influence of essential minerals other than Na in diet preferences.
