=== Oestrous Behaviour ===

=== Oestrous Behaviour ===

The proportion of females displaying strong oestrus behaviour is usually small and not all the females will show all these signs, despite the presence of a [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|mature follicle]]. Also, receptivity to the male can be displayed by females with no [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicles]] in the [[Camelids_%28LLamas_%26_Alpacas%29_-_Female_Anatomy_-_Anatomy_%26_Physiology#Ovary|ovaries]] and for up to 7 days after [[The_Ovary_-_Ovulation_-_Anatomy_%26_Physiology|ovulation]] or when pregnant and progesterone levels are high. Oestrous behaviour therefore cannot be used reliably to decide the timing of breeding.

* Unless she had an [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|immature follicle]] at mating, thus did not [[The_Ovary_-_Ovulation_-_Anatomy_%26_Physiology|ovulate]], this process will happen for at least 5-6 days.
