In this study, the antler producing performance of the Northeast Sika Deer was analyzed. The results showed that the antler production of Changsha Experimental Deer Farm remained in a stable level. There was a curve relationship between antler production and deer age. No relationship was doundin antler output between the first harvest and the second harvest. However, antler production was significantly related to deer's live weight. These results provided a reference evidence for the development of deer farming in southern China.
