The basic procedure for AI to occur is the following
- ovary scans to predict the day of ovulation (this may take multiple scan depending on where the mare is in her cycle)
- ordering the semen at the correct time to ensure enough time for collection and shipping
- Insemination of the mare
- Pregnancy scan
The ideal time to start scanning is well before the mare is on heat, if left too close to visible heat there may not be time to receive the semen for the AI.
