Genomic-enhanced expected progeny differences (EPDs) for multiple carcass traits are calculated using the American Angus Association carcass and ultrasound data
in combination with the IGENITY profile for Angus. Together, the information provides a more thorough characterization of economically relevant traits with im-
proved accuracy on young animals. Additional traits are also evaluated, and producers can access the Igenity profile scores on traits not currently expressed in EPDs
Calving Ease Direct (CED) characterizes an animal’s
genetic potential for unassisted births in first-calf
heifers, with a higher value being more favorable to
influence calving ease.
Birth Weight (BW) is an indicator of calf weight, with
a lower value characterizing lighter birth weight
calves.
Weaning Weight (WW) is an expression of genetic
potential for calf weight at weaning, with a higher
value indicating more pounds of weaning growth
Average Daily Gain (ADG) describes an animal’s
genetic potential for post weaning rate of gain.
Directed toward the feedlot period, a higher value
indicates more average daily gain.
Yearling Weight (YW) describes an animal’s potential
for post weaning gain measured near one year of age,
with a higher value reflecting more total pounds.
Residual Feed Intake (RFI) describes an animal’s feed
intake above or below its predicted need for mainte-
nance and growth. Lower scores indicate less intake
Dry Matter Intake (DMI) is an expression of feed
intake on a dry matter basis. A higher value
characterizes more feed consumed by the animal,
while a lower value indicates the animal has potential
to eat less feed.
Yearling Height (YH) characterizes an animal’s
genetic potential for height or frame, with a higher
value indicating more yearling size measured at the
hip.
Scrotal (SC) characterizes an animal’s genetic
potential for scrotal circumference, with a higher
value indicating more yearling scrotal size.
Docility (DOC) is the animal’s genetic potential to be
extremely calm, or to have calm offspring. Higher
values indicate an improvement in cattle
temperament.
Heifer Pregnancy (HP) is used as a tool to increase
the chance of a sire’s daughters becoming pregnant
during a normal breeding season. Higher scores are
considered more favorable.
Maternal Calving Ease (CEM) characterizes an
animal’s genetic potential for unassisted births in
first-calf daughters. A higher value would indicate
more favorable genetics for the ease with which
daughters calve as first-calf heifers
Maternal Milk (MILK) is an indicator of milk and
mothering ability as expressed in daughters. A higher
value characterizes more milk expressed in pounds of
weaning weight in a daughter’s calves.
Mature Weight (MW) is an expression of genetic
potential for mature cow weight at six years of age,
with a higher value indicating larger cow size in
pounds.
Carcass Weight (CW) is a genetic predictor of hot
carcass weight as measured at harvest time. A higher
value characterizes more pounds expressed.
Marbling (MARB) is an expression of the potential to
improve the USDA marbling score, which is used to
predict Quality Grade in beef cattle. A higher value
indicates a higher marbling score.
Ribeye Area (RE) is a predictor of ribeye area in a
carcass of a sire’s progeny compared to progeny of
other sires. A higher value indicates a larger ribeye
area.
Fat Thickness (FAT) is a predictor of the differences in
external fat thickness as measured between the 12th
and 13th carcass ribs. Lower scores indicate less
external fat.
Tenderness (TEND) represents the genetic potential
for tenderness as measured by the Warner Bratzler
shear force test, with the higher profile scores being
more tender than lower scores.
