Giraffes reach sexual maturity at 3-4 years of age, although, in the wild, males may not breed until ages 6 or 7, due to a system of hierarchy among bulls. Breeding can occur at any time of the year. Gestation is usually 13-15 months.
However, infant mortality is high among giraffes. Approximately 50 percent of giraffe calves do not survive past six months.Although giraffes can live up to 30 years in captivity, the normal life span in that type of setting is approximately 13 years for bulls and 17 years for cows.
