Dosage Figures for Kentucky Derby Winners Since 1940

The following table lists the Dosage figures, sire, broodmare sire, sire lines  and bloodline crosses for winners of the Kentucky Derby since 1940.  Since the table was initially constructed in the early 1980's, the figures are those of the horse at the time.  Therefore, some of the numbers in the table are different from the current numbers calculated using subsequent chef-de-race additions.  The current figures for all of the Derby winners can be found in the Triple Crown pedigree section.  Sire lines represent a major branch point in the direct male line.  For example, the Nasrullah line includes all Derby winners not tracing back to Nasrullah through Bold Ruler.  Similarly, the Sickle line includes all Derby winners not tracing back to Sickle through Raise a Native or Native Dancer.   Other relationships of the same kind include Hyperion-Gainsborough and Northern Dancer-Nearctic.  Bloodlines refer to Phalaris (P) or non-Phalaris (NP).
