This study carried out to investigate the effect of cutting stimulation on time of cutting, yield and length of antler in Sika deer. There was no significance between surgical stimulation and length of antler, but length was the longest in one side cutting group and the shortest in both side cutting group. Development of point was increased as the number of wounds in the second year (P<0.05). Time of casting was 2 weeks earlier in one side cutting group (P<0.05) than in both sides cutting group. Yields of velvet antler were 148±23g when pedicle was not cut, and 126±61g, 179±63g, 170g, and 48±25g when pedicle was cut by 0.3cm, 0.4cm, 0.5cm and 0.6cm thickness, respectively. In case of 0.6cm, yield was significantly smaller than others (P<0.05). The most desirable thickness of pedicle cut was 0.4～0.5mm. Yield of antler was increased as the size of wound in the first year, and 588, 790 and 657g in control, one-cut and both-cut, respectively. Yields of antler in one-cut is significantly high (P<0.05).
