Like many young couples starting out, we were full of hope for the future. Hope that one day we would have a family with two, maybe even three, children. Like many couples we also waited until the time was right to start our family.

We had been married three years and my husband left halfway through a three-year tertiary course to go back to work so that I could stop work to look after a baby. We were pleasantly surprised when I fell pregnant after only one month of trying. Being a teacher, the timing was great as I could finish out the year with the baby born close to the Christmas holidays. I knew the first 12 weeks were crucial but remained quietly confident because miscarriage happens to other people, not me.
Desperately I wanted to see my baby on the week scan but had decided not to go for the pre-screening tests. My husband and I are practising Christians and had decided that we would love any child. I said those words to my midwife so flippantly that I never knew the next few months would test those words and our faith to the core. My midwife recommended a dating scan.

Generally the view is that the sooner you know about something, the easier it will be to treat and the better the outcome. However, there is also evidence that for all the good they can potentially do, ultrasounds could possibly be harmful to the growing fetus, being linked in recent years to various neurological problems, intra-uterine growth restriction, and other health problems, and the scans may not even make any significant difference to the outcomes for those infants in whom a congenital abnormality is detected.

Foetal ageing is the assignment of an estimated age of a foetus in days at the time of ultrasound scanning within the first trimester within the first months of pregnancy. During this period the foetus undergoes a uniform growth and development pathway that can be easily visualised through real-time ultrasonography. With practice and regular calibration, ultrasound scanners can assess foetal age from the real-time images of the foetus and associated tissues of pregnancy.
An assessment of foetal age at time of scanning provides a valuable piece of information on the hind: an estimate of the date she conceived. This is calculated simply by subtracting the foetal age in days from the date of scanning. In the case of commercial herds, this information can be used by producers to manage calving groups by assigning hinds to groups based on expected calving date. It is therefore possible to select our breeding herds for an earlier calving season to better match pasture growth with feed demand by deer.
The only reliable phenotypic measure of this trait is conception date based on foetal ageing for each breeding hind. This requires that hinds are joined early i. Where a birth date is estimated without reference to a conception date for a progeny crop, calculated growth rates related to weaning date favourably bias the calves born earlier than the estimated date and unfavourably bias the calves born later than the estimated birthing date. Conception date profiling of hinds by foetal ageing will provide a more reliable proxy birth date for each calf, such that other DEERSelect data on the calf will be more reliable as a whole.
