If Predicted Producing Ability (PPA) is the most important line of the pedigree when buying milking animals, then the P-level may be the most important guide on the pedigree when buying heifers.

The P-level is a percentile ranking of the Parent Average (PA) Jersey Production Index™ (JPI) and/or PA Protein. Click here for the current tables (April 2008).

The percentile rankings P0 through P9 are displayed. Percentile rankings are based on registered animals born within a given year. The P-level indicated of how this individual ranks compared to others born in the same year.

To interpret, insert the P-level in the blank in the following statement: “This heifer has a higher PA JPI (Protein) than __0 percent of the registered Jersey heifers born in the same year.” A P9 heifer born in 2006 has a higher PA JPI and/or PA Protein than 90 percent of the Registered Jersey heifers born in 2006.
