Ultrasound scans are an important component of the yearling measures collected. These records on your registered animals can be used to generate carcass expected progeny differences (EPDs). It is important to know the requirements for ultrasound scans to be eligible for use in EPD calculations. Otherwise, missed age windows and improper contemporary grouping can negate the use of the scan in genetic predictions. Fig. 1 illustrates the chain of events from the time you wean your calves, submit weaning information, and ultimately receive ultrasound reports from the Association.
