To investigate the effects of CaCl2 on artificial induction of antlerogenesis in female deer, various CaCl2 conditions with different concentrations, dosages and times were treated to five female Elk(Cervua Canadensis). After injection of CaCl2 solution to the putative region of antlerogenesis, rate of induction, yield of antler, length of antler, number of point were examined. In regard to the effect of concentration of CaCl2 solution on the induction of antlerogenesis in the female deer, generation of pedicle and antler has not induced under treatment of 2ml and 3ml of 15％ solution, but only pedicle has generated with 4ml of 15％ solution, otherwise generation of pedicle and antler has induced under treatment of 1.5ml, 2ml and 3ml of 30％ solution and 1ml and 2ml of 50％ solution. The yields of antler were 319g in 4ml of 15％ solution, and 1,290g, 513g and 295g in 1.5ml, 2ml and 3ml of 30％ solution, respectively, and 800g and 443g in 1ml and 2ml of 50％ solution, respectively. The yields of antler of 30％ solution and 50％ solution were decreased with increase the dosage volume. The maximum yield of antler was 1,290g at 30％ 1.5ml treatment. The length of antler were 25cm in 15％ 4ml treatment, and 55cm, 51cm and 35㎝ in 1.5ml, 2ml and 3ml of 30％ solution, respectively, and 60cm and 35cm in 1ml and 2ml 50％ solution, respectively. There was a tendency that length of antler became longer as yield of antler were grew. The numbers of point were 2 in 15％ 4ml treatment, and 5, 2.3 and 1 in 1.5ml, 2ml and 3ml of 30％ solution, respectively, and 3 and 1 in 1ml and 2ml of 50％ solution, respectively. The number of point was not related to concentration and dosage of CaCl2 solution, but related to the shape of wound due to the time and method of injection. Consequently, the optimum concentration of CaCl2 solution for artificial induction of antlerogenesis in female elk is 30%.
