GPFT (Productivity, Functionality and Type)

GPFT is the selection index of the Italian Holstein breed, which combines milk produc- tion, functionality and type. The official ranking is based on GPFT and ranges from 0 to 99 dividing the population in percentiles. The ranking is calculated separately for bulls and cows. The rank 99 identifies the best 1% of bulls and cows. Since December 2011, rank 98 (best 2% of the population) is the official limit for a bull to be used in A.I. The following table shows the relative weight of each trait included in GPFT.
