Consequently, all bulls listed in the current USDA-DHIA Active Al Sire Summary should be readily av' through established A! marketing systems. The Predicted Differences (PD's) for milk (POM) and fat (PDF) yields and fat percentage (PD%) are expressed relative to t genetic bases for those traits. Therefore, the PD's from the July Sire Summary run, especially those for milk and fat yields a different magnitude from those from runs prior to January Dairy producers are encouraged to pay close attention percentile ranking of each bull to help interpret the genetic superiority represented by the PD's for yield traits relative to ti genetic bases.
