The estrous cycle is the cycle of a non-pregnant female mammal that goes through a luteal phase and a follicular phase. Estrus is the period in which an animal will stand to be bred, and is part of the follicular phase of the estrous cycle. An easy way to remember it is that estrous is an adjective and estrus is a noun. Thus, estrous refers to the entire cycle, whereas estrus just refers to the phase in which the animal can get pregnant. Usage: The female chimpanzee can get pregnant because she is in estrus. The female chimpanzee can get pregnant in this phase of her estrous cycle.

Which animal? They're all different.
The estrous cycle of pigs is 21 days. Humans have a menstrual cycle which can last from 21-35 days.
Endometrial bleeding occurs during the menstrual cycle. The endometrium is reabsorbed by the uterus during the estrous cycle.
Estrous cycle
no rats have an estrous cycle, not a mestrual cycle.
The length of estrous for cattle is approximately 21 days. The estrus period last about 18 hours.
Usually 21 days, more or less.
No, they have an estrous cycle rather than a menstrual cycle where the endometrium is absorbed rather than expelled.
The typical menstrual cycle length is around 28 days, but everyone is different. It's also perfectly normal for there to be a few days variation from one cycle to the next cycle.
Humans and chimpanzees are the only animals that have "periods" or menstrual cycles. Other animals of the animal kingdom undergo Estrus, or heat periods (spikes in Estrogen output) during their Estrous cycle.
