Sexual maturity of the female is at 48-60 months, the male is at 42 months. The giraffe mate at any time of the year with the gestation period being between 453 - 464 days. There is usually only one calf, very rarely twins. A giraffe cow in season attracts males from all around, but is soon won by a dominant bull. The male signals his readiness to mate by tapping on the female's hind leg with his foreleg or resting his chin on her back. He usually follows her, sometimes for hours, until she allows him to mount her

Giraffes don't have a set mating season. Instead they have an estrous cycle, which is a lot like the human menstrual cycle (but with less blood and slightly different hormones). The male giraffes don't just mate with the ladies all the time, so they generally try to find a way to determine is the lady is fertile.www.interiorsafarisea.com
