+ ~ Good Plus, 80% to 84% of the ideal

# Daughters ~ Number of daughters that actually contributed to a genetic evaluation

# Fat ~ DHIR reported pounds of fat produced

# Herds ~ Number of herds containing daughters that have contributed to a genetic evaluation

# Milk ~ DHIR reported pounds of milk produced

# Pro ~ DHIR reported pounds of protein produced

% Fat ~ DHIR reported percent butterfat produced

% Pro ~ DHIR reported percent protein produced

A ~ Acceptable, 70% to 79% of the ideal

Age ~ Animal’s reported age for record

Avg Dau Production ~ Average lbs of milk per daughter

Avg Dau Score ~ Average score of daughters

Avg Lact per Dau ~ Average # of lactations per daughter

BA/Buck Abbreviation ~ A name abbreviation, comprised of an alpha/digit code of four characters, assigned by the consignor for use when registering the buck’s progeny.

BC ~ Body Capacity

Buck Type Evaluation ~ Evaluates individual type traits, by way of the linear appraisal system, that affect structural and functional durability. This evaluation enables a breeder to take full advantage of the potential for genetic improvement through selection.

Buck Yield Evaluation ~ Evaluate individual production traits using information from DHI milk testing as they are reported on herds with daughters of that buck.

DC ~ Dairy Character

DOB ~ Buck’s date of birth

E ~ Excellent, at least 90% of the ideal

ETA ~ (Estimated Transmitting Ability) An average of the PTI’s of the sire and dam which are used as predictors of the genetic potential of the resulting offspring. ETA’s are weighted to favor production in the ratio of 2:1, and type in the ratio of 1:2.

F ~ Fair, 60% to 69% of the ideal

FS ~ Final Score

GA ~ General Appearance

HES ~ Herd Evaluation Service score

Index # ~ Buck’s cane and straw code, to be used when placing an order

LA ~ ADGA official Linear Appraisal score

M ~ Mammary

P ~ Poor, less than 60% of the ideal

PTA/Predicted Trans Ability ~ (Predicted Transmitting Ability) The genetic evaluation for a specific trait using information from DHI milk testing and/or ADGA Linear Appraisal programs for each production/type trait based on progeny data. PTA’s are generated for each of the available components for DHI being milk production, butterfat and protein. The type components from Linear Appraisal are each of the thirteen linear traits and the final score. PTA’s compare the genetic value of animals to each other within their gender and breed.

PTI/Production Type Index ~ The genetic evaluation for production and type combined, as compared to animals of the same gender and breed. Values are derived from the PTA for Linear Appraisal final scores and energy corrected milk which is generated from the PTA’s for butterfat, protein and milk production. PTI’s are weighted to favor production in the ratio of 2:1, and type in the ratio of 1:2.

REG # ~ Buck’s registration number

% Reliability ~ The accuracy of the PTA genetic evaluation expressed as a percentage. The more female offspring evaluated per buck, and the more herds in which they reside, the higher the reliability. The higher the reliability percentage, the more accurate the proof, and the less susceptible it is to large changes when new information is added.

Straw ~ Price for a broken unit/single straw (includes a $5.00 handling charge)

Unit ~ Total Price for a unit of five straws

V ~ Very Good, 85% to 89% of the ideal

Verified Data ~ Data that has been verified with the Breed Registry or designated affiliate as true and correct.

YSA ~ ADGA official Young Stock Linear Appraisal score


In an effort to respond to the questions of ADGA members and dairy goat breeders regarding correct or “ideal” type, the American Dairy Goat Association Type Committee has adopted the following ideal ranges for the linear traits. The Committee suggests that members needing information regarding correct type, use these ranges along with the drawings in ADGA’s Linear Appraisal System Booklet as a resource in evaluating type. Animals fitting within the range of numbers listed for each of the individual traits will be considered to be approaching ideal, or are extremely correct in that trait.
