- Oestrus detection is important, for although the queen is an induced ovulator (thus ovulation will not be missed, the LH response to mating decreases with each day of oestrus and follicles ultimately regress.
- Proestrus is short and often unnoticed.
- Oestrus is characterized by increased vocalization,rubbing and rolling.
- Queen is more active and will seek the tom.
- Stands to be mated by lowering her front quarters and extending her hind legs.
- Demonstrates lordosis
- Tail erect and held to one side.
- Slight mucoid vulval discharge.
