== Rejection Behaviour ==
* Rejection of the male usually indicates that conception may have taken place.
* Not very reliable, since a persistent corpus luteum will also cause rejection.
** A persistent corpus luteum may cause continued rejection by a non-pregnant female.
== Ultrasound Scanning ==
Ultrasound scanning is the most reliable method of diagnosing pregnancy and can be highly accurate. However, ~10% of established pregnancies fail, so a positive scan will not guarantee live cria.
* Possible only a few days after conception.
* For early scans, a rectal probe must be used.
** Rarely practiced because the procedure causes much stress to the female, which is undesirable if she is pregnant.
* More commonly scanned using a transabdominal probe from ~28 days onwards.
== Ultrasound Scanning ==
== Blood Testing ==
* Blood tests to measure progesterone concentration.
* Level of progesterone required to maintain pregnancy varies.
** Cria have been born to dams with very low plasma progesterone concentrations.
* Variability makes blood tests unreliable.
== Rectal Examination ==
== Rectal Examination ==
* Manual palpation of the [[Uterus - Anatomy & Physiology|uterus]] through the rectal wall.
* Impractical for smaller females.
* Will cause undesirable stress to the female.
== Foetal Heartbeat ==
== Foetal Heartbeat ==
* Specialist listening devices such as 'Sonicaid' can detect a foetal heartbeat from ~10 weeks of gestation.
* 80-90% accurat if used at ~10 weeks.
* Becomes more difficult as the foetus enlarges and slides down into the abdomen.
