The estrus cycle consists of four main stages: proestrus, estrus, metestrus, and diestrus. Proestrus is the period before ovulation, characterized by the growth of follicles. Estrus is the mating period when the female is receptive to males. Metestrus is a transition stage after ovulation, and diestrus is a period of sexual inactivity if fertilization did not occur.
Vaginal epithelial cells in the estrous cycle are most commonly observed during the proestrus stage. This is when the cells undergo changes in preparation for estrus, such as an increase in the number of cornified epithelial cells. Dinoflagellate cells are also sometimes seen during this stage.

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.

Anestrus or Diestrus. Proestrus is when the female is about to go into estrus, and Metestrus is the period before Diestrus and after Estrus which the female goes out of heat and ovulation ends.
The length of estrous for cattle is approximately 21 days. The estrus period last about 18 hours.
A female dog's heat cycle or estrus typically lasts around 2-4 weeks. This cycle is divided into four stages: proestrus, estrus, diestrus, and anestrus. During the estrus stage, which is when she is fertile, the female dog may actively seek out males for breeding.
She will bleed a little a couple days after estrus.
Most female does have their first estrus cycle between six and twelve months.
because it does When she is in her estrus cycle the scent attracts the male.
Estrogen is the hormone responsible for the occurrence of estrus in female mammals. It helps regulate the reproductive cycle and brings about the physical and behavioral changes associated with being in heat.
A cow's estrous cycle typically lasts about 21 days. This is the period of time between one heat (or estrus) and the next.
Rabbits do not have a typical estrus cycle as other mammals. Rabbits are stimulated to ovulate by the mating act, and as such, can be ready to mate and conceive again as soon as they drop each litter -- approximately every 30 days.
