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.

* 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.

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.
