Help with DP, DI, and CD

Question
I have a Thoroughbred Mare that I got 5 years ago. Her previous Information is vague and I know nearly nothing about what she has done. I have her Papers and I would like to know what The DP, DI and CD stands for. Her numbers are

Dp:7-4-13-0-6
Di:1.40
CD 0.20

Thank you very much.

Answer
Hi Haley:

The Dosage Index (DI) is simply a mathematical formula that predicts a horse's stamina based on its pedigree.  The numbers in the first two categories, if high, [Brilliant (7) and Intermediate (4)] are supposed to be representative of a speed pedigree, as compared to the last two [Solid (0) and Professional (6)], which, if high, would be indicative of ancestry blessed with stamina.

Your mare's numbers (DI 1.40, CD .20) are basically average, an indication that she, and her relatives and/or progeny, probably negotiated sprints and distance races with equal success (in actuality, 1.00 is average for DI, while 0.00 would be the average for CD).  

I wouldn't put too much stock in these calculations, though.  While certainly useful and informative, they should only be used as a guide in determining the attributes of a racehorse.
