What is Anoestrus?

Explanation:
Anoestrus is a period of reproductive quiescence when the animal has no regular oestrous cycles and the ovaries are inactive. During this time the hormonal signals driving the cycle are suppressed, ovarian follicles don’t mature, and there is no ovulation or heat behavior. It can occur in seasonal breeders, after parturition with lactational anestrus, or due to illness or stress that suppresses cycling. This makes it distinct from being pregnant, from being in perpetual heat, or from high fertility.
