* The first ovulation is usually not accompanied by behavioural [[Reproductive_Behaviour_-_Oestrus_Behaviour_-_Anatomy_%26_Physiology|oestrus]] in heifers and ewes and is hence termed 'silent ovulation'. Thus, the age at first [[Reproductive_Behaviour_-_Oestrus_Behaviour_-_Anatomy_%26_Physiology|oestrus]] may not accurately reflect acquisition of puberty.
