What is the estrus or heat cycle of an elephant?

The estrus cycle in elephants is 13 – 18 weeks and each estrus or heat lasts for 2 to 6 days. The meaning is that a mature cow (a female elephant) will only allow a bull (a male elephant) to mount on her within the 2 to 6 days of heat. If there is no conception, the female elephant will allow the male again until after 13 to 18 weeks when she comes on another heat.
