The treatment used in this research was in injection of hCG with defferent doses is : P0: Control using NaCl 0,9% as much 0,2 ml/kg body weight, P1: Injection of hCG with dose 300 IU/kg body weight, P2: Injection of hCG with dose 500 IU/kg body weight, P3: Injection of hCG with dose 700 IU/kg body weight. The result showed that hCG dose of 500 IU/kg of body weight was the best in turn of latent time obtained 7 hours 54 minutes, number of eggs resulted 323stripping, increase in egg diameter 0,09 mm, increase egg maturity 18% and ovisomatic index value 14%.
