It is a percentile ranking of the animal’s Jersey Production Index™, displayed as P0 through P9. P-level is based upon Parent Average JPI, or genomic JPI when available. The P-level indicates how one animal ranks compared to all other registered Jerseys of the same sex born in the same year. To interpret, insert the P-level in the blank in the following statement: “This heifer (bull) has a higher PA JPI than __0 percent of the registered Jersey heifers (bulls) born in the same year.” Example: A P8 heifer born in 2020 has a higher PA JPI than 80 percent of the Registered Jersey heifers born in 2020. The tables show means and minimum values for percentile ranking levels based on Parent Average JPI for the birth years 2017 to 2021 and projected for 2022 and 2023. P-levels are printed on Official Performance Pedigrees for heifers, but not for bulls. Table 1.
