    A BUCK, +*B , will have some of the above lines and a line that looks like:
    D/AV 2574 91 68 79

    *B Stars on bucks are earned by virtue of parents with production records meeting ADGA minimums

    +B Plusses on bucks are earned by virtue of offspring meeting ADGA requirements

    2*M Two Star Milker - Second successive generation of a doe line that has earned a star based on minimums set forth by ADGA

    PTA Predicted Transmitting Ability – Computed by USDA AIPL, incorporating data from production and type data of the doe, ancestors, collateral relatives and progeny. The first three numbers are the estimates of the pounds of milk to expect from each lactation of a parents' future daughter when compared to a herdmate of breed average genetic merit. The last is the PTA of change to the Type score. PTA expresses the level of genetic superiority that an animal transmits to its offspring for a given production or type trait. This value is used to rank animals based on their genetic merit.

    DEV Standard Deviation that can be expected in pounds.

    P(redicted) T(ransmitting) A(bility) $(dollars) is an economic index that combines relative values of milk and components. Estimates the extra income a dairyman would receive in each lactation based on values supplied by USDA for fat and protein differentials. The first number is fat; the second is protein.

    15 13 32R(eliabity) in % -

    Reliability measures confidence in the PTA Values - 99 is highest. An animal's reliability is based on the information available in the evaluation. The R in this area is for TYPE.

    PTA% P(redicted) T(ransmitting) A(bility) %(percentage). Milk fat (.07) and milk protein (.04). Dates are of last calculations; the first is production and the second is type.

    PTI P(roduction) T(ype) I(ndexes) – genetic indexes that combine production and type genetic evaluations into one score. First number emphasizes production over type and second emphasizes type. Zero would be no change.

    133 (2:1) 134 (1:2)

    ETA E(stimated) T(ransmitting) A(bility) – Estimate of a buck’s future PTA’s (as an index) for production and type. Production is first; type is second. Zero is no change.
