=== Oestrus ===
=== Oestrus ===
* The period where the female will accept the male for [[Reproductive_Behaviour_-_Copulatory_Behaviour_- Anatomy & Physiology|copulation]].
* The period where the female will accept the male for [[Copulatory Behaviour - Anatomy & Physiology|copulation]].
* The onset and end of oestrus are the only stages of the oetrous cycle that can be accurately measured. They are therefore used to determine cycle length.

* Female seeks out the male and 'stands' to be mounted.

* [[The_Ovary_-_Ovulation_- Anatomy & Physiology|Ovulation]] occurs during this phase in all domestic species except the cow.
* [[The_Ovary_-_Ovulation_- Anatomy & Physiology|Ovulation]] occurs during this phase in all domestic species except the cow.
** The cow [[The_Ovary_-_Ovulation_- Anatomy & Physiology|ovulates]] ~12 hours after the end of oestrus.
** The cow [[The_Ovary_-_Ovulation_- Anatomy & Physiology|ovulates]] ~12 hours after the end of oestrus.
* [[The_Ovary_-_Ovulation_- Anatomy & Physiology|Ovulation]] is spontaneous in all domestic species except the cat, rabbit and camelids. In these species it is induced by the act of [[Reproductive_Behaviour_-_Copulatory_Behaviour_- Anatomy & Physiology|copulation]].

* During pro-oestrous and oestrus there is [[Ovary - Anatomy & Physiology#Folliculogenesis|follicular growth]] with no functional [[Corpus Luteum - Anatomy & Physiology|corpora lutea]] present on the [[Ovary - Anatomy & Physiology|ovary]] (aka follicular phase).

* The main ovarian hormone production is Oestrogen.
