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 2 ml and 3 ml of 15％ solution, but only pedicle has generated with 4 ml of 15% solution, otherwise generation of pedicle and antler has induced under treatment of 1.5 ml, 2 ml and 3 ml of 30% solution and 1 ml and 2 ml of 50% solution. The yields of antler were 319g in 4 ml of 15% solution, and 1,290g, 513g and 295g in 1.5 ml, 2 ml and 3 ml of 30% solution, respectively, and 800g and 443g in 1 ml and 2 ml 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% 1.5 ml treatment. The length of antler were 25 cm in 15% 4 ml treatment, and 55 cm, 51 cm and 35 cm in 1.5 ml, 2 ml and 3 ml of 30% solution, respectively, and 60 cm and 35 cm in 1 ml and 2 ml 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% 4 ml treatment, and 5, 2.3 and 1 in 1.5 ml, 2 ml and 3 ml of 30% solution, respectively, and 3 and 1 in 1 ml and 2 ml 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%.
