Abstract
The aim of this study was to provide basic information to allow improved feeding management for velvet antler production by investigating the effects of dietary protein level on production and chemical composition of velvet antler in spotted deer(Cervus nippon). Eighteen male spotted deer of 5~6 years old were assigned to 3 unreplicated groups by production record of the previous year. Deer were fed on experimental diets at different protein level of 10%(T1), 15%(T2) and 20%(T3). Dry matter intake, crude protein intake and daily gain were increased with increasing the protein level in diets and there were significant differences(P<0.05) between groups. Although not significant, mean length of main beam tended to be longer in either left or right beam with increasing the protein level, and in girth at part of base of main beam, it was a similar pattern to the result of length. The velvet antler production was affected by dietary protein level and thus that was the smallest in T1 and the largest in T3(P<0.05). The content of crude protein in velvet antler was higher in T1 than in T3, whereas the content of crude ash in velvet antler was contrast to that of crude protein, however, there were no significant differences.
