*Marbling score units: 4.00 = S100; 5.00 = Sm00. Note that Brahman EPDs for marbling are reported on a scale where 400 = SI00 and 500 = Sm00• When converting sires from other breeds to a Brahman basis, the adjusted EPD should be multiplied by I00. Likewise, when Brahman EPDs are adjusted to other breeds, the EPD should be divided by 100 before adding the adjustment factor.
It is important to note that the table factors do not represent a direct comparison among the different breeds because of base differences between the breeds. They should only be used to compare the EPDs (AB-EPDs) of animals in different breeds. To reduce confusion, breed of sire means (i.e., one half of full breed effect; breed of sire means predict differences when bulls from two different breeds are mated to cows of a third, unrelated breed) for animals born in 2023 under conditions similar to USMARC.
AUXILIARY INFORMATION
Expected Progeny Difference (EPD) – The prediction of how future progeny are expected to perform relative to progeny of other animals within the same database. EPDs are expressed in units of measure for the trait, plus or minus.
Accuracy (Acc) – The reliability that can be placed on the EPD. An accuracy of close to 1.0 indicates higher reliability. Accuracy is impacted by the number of progeny and ancestral records in the analysis.
$Value Index ($Value) – An economic selection index allowing for directional change in multiple traits at once pertaining to a specific breeding goal. The $Value is a collection of EPDs weighted by their economic value such that traits with greater impacts on the production goals have a larger economic weight associated with them.
PRODUCTION EPDS
Calving Ease Direct EPD (CED) – Expressed as a difference in percentage of unassisted births, with a higher value indicating greater calving ease in firstcalf heifers.
Birth Weight EPD (BW) – Expressed in pounds, is a predictor of a sire’s ability to transmit birth weight to his progeny compared to that of other sires.
Weaning Weight EPD (WW) – Expressed in pounds, is a predictor of a sire’s ability to transmit weaning growth to his progeny compared to that of other sires.
Yearling Weight EPD (YW) – Expressed in pounds, is a predictor of a sire’s ability to transmit yearling growth to his progeny compared to that of other sires.
Residual Average Daily Gain EPD (RADG) –Expressed in pounds per day, is a predictor of a sire’s genetic ability for postweaning gain in future progeny to that of other sires, given a constant amount of feed consumed.
Dry Matter Intake EPD (DMI) – Expressed in pounds per day, is a predictor of difference in transmitting ability for feed intake during the postweaning phase, compared to that of other sires.
Yearling Height EPD (YH) – Predictor of a sire’s ability to transmit yearling height, expressed in inches, compared to that of other sires.
Scrotal Circumference EPD (SC) – Expressed in centimeters, is a predictor of the difference in transmitting ability for scrotal size compared to that of other sires.
MATERNAL EPDS
Heifer Pregnancy EPD (HP) – A selection tool to increase the probability of a sire’s daughters becoming pregnant as first-calf heifers during a normal breeding season. A higher EPD is the more favorable direction and the EPD is reported in percentage units.
Calving Ease Maternal EPD (CEM) – Expressed as a difference in percentage of unassisted births with a higher value indicating greater calving ease in firstcalf daughters.
Maternal Milk EPD (Milk) – A predictor of a sire’s genetic merit for milk and mothering ability as expressed in his daughters compared to daughters of other sires. In other words, it is the part of the calf’s weaning weight attributed to milk and mothering ability.
Teat Size EPD (Teat) – Expressed in units of teat score size, with a higher EPD indicating a sire will produce daughters with smaller teat size compared to that of other sires’ daughters.
Udder Suspension EPD (UDDR) – Expressed in units of udder suspension score, with a higher EPD indicating a sire will produce daughters with tighter udder suspension compared to that of other sires’ daughters.
Functional Longevity EPD (FL) – Expressed in number of calves, is a predictor of the number of calves a sire’s daughters are predicted to produce by 6 years of age compared to that of other sires’ daughters. A higher EPD is the more favorable direction indicating more calves produced on average.
Mature Weight EPD (MW) – Expressed in pounds, is a predictor of the difference in mature weight of a daughters of a sire compared to the daughters of other sires.
Mature Height EPD (MH) – Expressed in inches, is a predictor of the difference in mature height of a sire’s daughters compared to daughters of other sires.
Cow Energy Value ($EN) – Expressed in dollar savings per cow per year, assesses differences in cow energy requirements as an expected dollar savings difference in daughters of sires. A larger value is more favorable when comparing two animals (more dollars saved on feed energy expenses). Components for computing the cow $EN savings difference include lactation energy requirements and energy costs associated with difference in mature cow size.
MANAGEMENT EPDS
Docility EPD (Doc) – Expressed as a difference in yearling cattle temperament, with a higher value indicating more favorable docility.
Claw Set EPD (Claw) – Expressed in units of clawset score, with a lower EPD being more favorable indicating a sire will produce progeny with a more ideal claw set. The ideal claw set is toes that are symmetrical, even, and appropriately spaced.
Foot Angle EPD (Angle) – Expressed in units of foot-angle score, with a lower EPD being more favorable indicating a sire will produce progeny with more ideal foot angle. The ideal is a 45-degree angle at the pastern joint with appropriate toe length and hell depth.
Pulmonary Arterial Pressure EPD (PAP) –Expressed in millimeters of Mercury (mmHg), with a lower EPD being more favorable indicating a sire should produce progeny with a lower PAP score. PAP score is an indicator of susceptibility to high altitude disease commonly experienced at elevations greater that 5,500 feet. Selection for this trait aims to improve genetic potential for a sire’s progeny to have lower PAP scores, thus a lower chance of contracting high altitude disease increasing the environmental adaptability of cattle living in mountain areas.
Hair Shed EPD (HS) – Expressed in units of hair shed score, with a lower EPD being more favorable indicating a sire should produce progeny who shed their winter coat earlier in the spring. Selection for this trait should improve the genetic potential for a sire’s progeny to shed off earlier increasing the environmental adaptability of cattle living in heat stressed areas and producers grazing endophyteinfected (hot) fescue).
CARCASS EPDS
Carcass Weight EPD (CW) – Expressed in pounds is a predictor of the difference in hot carcass weight of a sire’s progeny compared to progeny of other sires.
Marbling EPD (Marb) – Expressed as a fraction of the difference in USDA marbling score of a sire’s progeny compared to progeny of other sires.
Ribeye Area EPD (RE) – Expressed in square inches, is a predictor of the difference in ribeye area of a sire’s progeny compared to progeny of other sires.
Fat Thickness EPD (Fat) – Expressed in inches, is a predictor of the differences in external fat thickness at the 12th rib (as measured between the 12th and 13th ribs) of a sire’s progeny compared to progeny of other sires.
ANGUS ON DAIRY $VALUE INDEXES
Angus-On-Dairy $Value Indexes – Bioeconomic selection indexes that allow multiple change in several different traits at once pertaining to a dairy-beef crossbreeding objective. These values are terminal crossbreeding indexes to estimate how future beef-on-dairy progeny of each Angus sire are expected to perform, on average, compared to beef-on-dairy progeny of other Angus sires if the sires were randomly mated and beef-on-dairy calves were exposed to the same environment.
Angus-On-Holstein Index ($AxH) – A terminal index, expressed in dollars per head, to predict profitability differences in progeny due to genetic traits weighted by appropriated economics of each Angus sire when mated to Holstein females. The underlying breeding objective assumes Angus bulls will be mated to Holstein females to produce Angusdairy crossbred calves to be fed and marketed on a quality-based grid. Traits included are as follows: calving ease, growth from birth through the feeding phase, feed intake, dressing percent, yield grade, quality grade, muscling, and height.
Angus-On-Jersey Index ($AxJ) – A terminal index, expressed in dollars per head, to predict profitability differences in progeny due to genetic traits weighted by appropriated economics of each Angus sire when mated to Jersey females. The underlying breeding objective assumes Angus bulls will be mated to Jersey females to produce Angus-dairy crossbred calves to be fed and marketed on a quality-based grid. Traits included are as follows: calving ease, growth from birth through the feeding phase, feed intake, dressing percent, yield grade, quality grade, and muscling.
ANGUS $VALUE INDEXES
Maternal Weaned Calf Value Index ($M) –Expressed in dollars per head, predicts profitability differences from conception to weaning with the underlying breeding objective assuming that individuals retain their own replacement females within herd and sell the rest of the cull female and all male progeny as feeder calves. The model assumes commercial producers will replace 25% of their breeding females in the first generation and 20% of their breeding females in each subsequent generation. Traits included are as follows: calving ease direct, calving ease maternal, weaning weight, milk, heifer pregnancy, teat size, udder suspension, functional longevity, docility, mature cow weight, claw set, and foot angle.
Weaned Calf Value Index ($W) – Expressed in dollars per head, to predict profitability differences in progeny due to genetics from birth to weaning. The underlying objective being producers will retain 20% of the female progeny as replacements and sell the rest of the cull females and their male counterparts as feeder calves. Traits included are as follows: birth weight, weaning weight, milk and mature cow weight.
Feedlot Value Index ($F) – Expressed in dollars per head, to predict profitability differences in progeny due to genetics for postweaning feedlot merit compared to the progeny of other sires. The underlying objective assumes producers will retain ownership of cattle through the feedlot phase and sell fed cattle on a carcass weight basis, but with no consideration of premiums or discounts for quality and yield grade. Traits contributing directly to the index are as follows: yearling weight (gain), carcass weight, and dry-matter intake.
Grid Value Index ($G) – Expressed in dollars per carcass, to predict profitability differences in progeny due to genetics for carcass grid merit compared to progeny of other sires. The underlying objective assumes producers will market cattle on an aboveindustry-average carcass grid. Traits included in the index are as follows: carcass weight, marbling, ribeye area, and fat.
Beef Value Index ($B) – A terminal index, expressed in dollars per carcass, to predict profitability differences in progeny due to genetics for postweaning and carcass traits. This terminal index assumes commercial producers wean all male and female progeny, retain ownership of these animals through the feedlot phase, and market these animals on a carcass grid. Traits included in the index are as follows: yearling weight, dry-matter intake, marbling, carcass weight, ribeye area, and fat.
Combined Value Index ($C) – Expressed in dollars per head, which includes all traits that make up both Maternal Weaned Calf Value ($M) and Beef Value ($B) with the objective that commercial producers will replace 20% of their breeding females per year with replacement heifers retained within their own herd. The remaining cull heifer and steer progeny are then assumed to be sent to the feedlot where the producers retain ownership of those cattle and sell them on a quality-based carcass merit grid. Expected progeny differences directly influencing this index are: calving ease direct, functional longevity, docility, mature cow weight, foot angle, claw set, dry matter intake, marbling, carcass weight, ribeye area, and fat thickness.

Total Maternal EPD (TM) – A value to predict the weaning weight performance of calves from an animal’s daughters due to genetics for growth and maternal ability. Total Maternal is calculated by adding ½ the WW EPD to the Maternal Milk EPD.
Residual Feed Intake EPD (RFI) – Expressed in pounds, predicts the differences in residual feed intake.
Age at First Calving EPD (ACF) – Expressed in days, predicts differences in age at when an animals’ daughters will calve.
Stayability EPD (ST) – Expressed as a percentage, predicts the differences of an animals’ daughters to remain in the herd through 5 years of age, and have a calf each year.
Terminal Index (TI) – An index used in the selection of terminal sires. It is designed to balance growth and carcass traits to maximize the value of animals that are marketed on a grid basis. The value is expressed on a per head basis. The traits that comprise the index are: YW, REA, IMF and Fat.
Maternal Index (MI) – An index used for selection of animals to produce replacement females. It is designed to balance weaning weight with cow maintenance and fertility. It is expressed as profit per cow exposed based on economically relevant traits. The traits that comprise the index are: BW, WW, Milk, YW, and SC.
Feed Efficiency Index (FEI) – An index used to select for feed efficient animals. It is designed to balance residual feed intake with post weaning growth. It is expressed on a per head basis and the traits that comprise the index are: RFI, WW, and YW.
CHAROLAIS INDEX & EPD
Total Maternal EPD (MTL) – A value to predict the weaning weight performance of calves from an animal’s daughters due to genetics for growth and maternal ability. Total Maternal is calculated by adding ½ the WW EPD to the Maternal Milk EPD.
Terminal Sire Index (TSI) – Is a formal method of combining Expected Progeny Differences (EPD) – BW, WW, YW, REA, CW, MARB, and FAT – into one single value on which to base selection decisions. The TSI uses estimates of the genetic relationships between traits with an economic default value based on three year rolling USDA data.
LIMOUSIN INDEXES & EPDS
Gestation EPD (GEST) – An evaluation of the gestation length of a sire’s progeny in days.
Total Maternal EPD (TM) – An index that combines growth and milk information as a prediction of the weaning weight performance of calves from a sire’s daughters. A greater TM value means a mother that returns comparatively higher weaning weights on her calves. TM = MK EPD + ½ WW EPD.
Stayability EPD (STAY) – Predicts the genetic difference, in terms of percent probability, that a bull’s daughters will stay productive within a herd to at least six years of age.
Yield Grade EPD (YG) – Differences in yield grade score, which is a predictor of percent retail cuts. Smaller values suggest that progeny will have a better lean to fat ratio.
Terminal Profit Index ($TPI) – This index has been constructed to identify sires that produce the highest profit potential for fed cattle utilizing traits that directly impact feeding performance and superior carcass traits. The index models the use of Limousin sires on Angus based cows with all calves marketed on a value-based carcass grid. The units reported represent expected differences in profit per mating.
$Gain Index ($G) – This index is used to find cattle that are superior for Feed Efficiency. $G for feed conversion represents the marginal value of gain over feed cost. The higher the $G sub-index EPD, is reflective of superior feed conversion of feed to pounds gained.
RED ANGUS INDEXES & EPDS
Maintenance Energy EPD (ME) – Predicts the difference in maintenance energy requirements, expressed in Mcal per month with lower values desired
Stayability EPD (STAY) – Predicts differences in the ability of an animal’s retained daughters to remain productive in the herd – calve every year – through 6 years of age; with a higher value being preferred.
Yield Grade EPD (YG) – Predicts differences in USDA Yield Grade, which is calculated using CW, REA, and Fat.
HerdBuilder Index (HB) – Is a maternal selection index that predicts the economic differences of animals for traits that are important from conception through weaning. Expressed in dollars per head born, HB is calculated based on the scenario that bulls are mated to heifers and cows, replacement heifers are retained and all remaining progeny are marketed at weaning. Traits included in this index are Calving Ease Direct, Calving Ease Maternal, Weaning Weight, Milk, Mature Weight, Heifer Pregnancy, and Stayability.
GridMaster Index (GM) – Is a selection index that predicts the average economic difference of non-replacement calves through the post-weaning phase of production. GM places selection pressure on growth, feedyard performance, and carcass traits. GM is calculated based on the scenario that progeny are fed out to slaughter and marketed on a quality-based carcass grid. Traits included in this index are Average Daily Gain, Carcass Weight, Dry Matter Intake, Marbling, Back Fat, and Rib Eye Area.
Profit and Sustainability Index (Pro$) – Is an all-purpose index that predicts average economic differences in all segments of the beef supply chain. This index is a combination of the breeding objectives modeled in the HerdBuilder and GridMaster selection indexes. In this index, replacement heifers are retained from within the herd and all remaining progeny are fed out to slaughter and sold on a quality-based grid. Traits included in this index are calving ease, growth, HPG, STAY, Mature Weight, Dry Matter Intake, and carcass traits. The resulting index is expressed in dollars per head born.
SIMMENTAL INDEXES & EPDS
Warner-Bratzler Shear Force EPD (SF) – Pounds of force required to shear a steak.
Stayability EPD (STAY) – Reported as the difference in probability of a sire’s daughters staying in the herd until 6 years of age, given that they calved as a 2-year old.
Yield Grade EPD (YG) – Reported as the difference in progeny USDA Yield Grade score units (1-5). Lower values represent leaner carcasses with more saleable beef.
All-Purpose Index (API) – Evaluates sires for use on the entire cow herd (bred to both Angus first-calf heifers and mature cows) with the portion of their daughters required to maintain herd size retained and the remaining heifers and steers put on feed and sold grade and yield.
Terminal Index (TI) – Evaluates sires for use on mature Angus cows with all offspring put on feed and sold grade and yield
$Gain Index ($G) – Expressed as the dollar difference per head per day during the post-weaning period. A prediction designed to identify animals that are more economically efficient in the feedlot converting feed into weight. It is a combination of Dry Matter Intake (DMI) EPD and Average Daily Gain (ADG) EPD, where ADG is weighted by the value of a pound of gain, and DMI is negatively weighted by the cost of a pound of dry matter.
WAGYU INDEXES & EPDS
Total Maternal EPD (TM) - A value to predict the weaning weight performance of calves from an animal’s daughters due to genetics for growth and maternal ability. Total Maternal is calculated by adding ½ the WW EPD to the Maternal Milk EPD.
%IMF Index (%IMF) – An animal’s expression of fat in the muscle, also known as marbling, measured within the ribeye at eh 12th and 13th rib interface.
Stearoyl-CoA desaturase Genotype (SCD) – A genotype in Wagyu cattle that is associated with the production of fat composition. The SCD gene encodes an enzyme that changes stearic acid into oleic acid, which is the more desirable fat acid in beef. The preferred genotype for this trait is AA (two copies of the gene), which correlates with a lower melting point in the intermuscular fat (IMF), making the fat softer and more palatable. The other possible SCD genotypes are VA and VV.
Tenderness Genotype (Tend) – A scoring system that ranges from 1-10, with higher scores being desired as they indicate more tender meat.
