New Research EPDs Released from American Angus Association®
Expanding the suite of maternal expected progeny differences (EPD), the American Angus Association® released three EPDs currently in the research format: functional Longevity (FL), teat size (TEAT) and udder suspension (UDDR).
The research phase of an EPD enables the membership to provide feedback and submit more records, and it gives the research team the opportunity to further investigate and to finetune models before the release of the production EPD. Research EPDs are updated periodically as additional data is received or updates to the models are released.
Functional Longevity (FL)
Profitability and sustainability of beef cattle production depend on many factors and cow longevity is certainly one of them. Angus breeders have ranked cow longevity as a priority.
Functional longevity is a selection tool that predicts, on average, the number of calves a sire’s daughters are expected to produce by six years of age compared with other sires’ daughters in the population. The trait is expressed in the number of calves produced with a higher EPD meaning that, on average, sires’ daughters are predicted to produce more calves by 6 years of age, compared with a lower EPD.
For example, if comparing two sires and sire A has a FL EPD of +1.5 and sire B has a FL EPD of +0.5, on average, the daughters of sire A are expected to produce one more calf by age six compared with the daughters of sire B.
Functional longevity, like other longevity or stayability traits, is lowly heritable (h2 = 0.09) and while the individual cow record is valuable in the evaluation, the bigger aggregate of information from sires’ daughters across the population helps building the accuracy of the EPD.
Data supporting FL includes more than 8.3 million production records from approximately 1.9 million females from both the American Angus Association members and Canadian Angus, as well as 1.5 million genotypes.
Teat Size (TEAT) and Udder Suspension (UDDR)
Good udder structure has an important role in beef production. Even though milk is not the end product from the beef production system, good udder structure is related to cow longevity and health, as well as calf survival and growth from birth to weaning.
To characterize udder structure, Angus females are scored within 24 hours of calving and can be evaluated every year they calve. The visual assessment of teat size and udder suspension is evaluated on the combined weakest quarter for both traits on scales of 1-9. A score of one represents a very large misshapen teat or a very pendulous udder, while a nine indicates a very small teat or a very tight udder.
Both TEAT and UDDR are moderately heritable traits, 0.32 and 0.28, respectively. The correlation between the two traits is 0.77, indicating they tend to move in the same direction (i.e., smaller teat and smaller udder), but they are not the same trait.
Teat size (TEAT) is expressed in units of teat size score, with a higher EPD indicating smaller teats. The teat size scores range from 9 (very small) to 1 (very large, balloon shaped). Longer, thicker teats inhibit calf suckling which could decrease the intake of colostrum and increase the risk of preweaning mortality.
Udder suspension (UDDR) is expressed in units of udder suspension score with a higher EPD indicating tighter udder suspension. The udder suspension scores range from 9 (very tight) to 1 (very pendulous). Weak suspension (low scores) indicates lack of support of the ligament that ties the udder to the cow’s body wall allowing the udder to hang low subjecting the udder to increased injury or other issues.
While overall smaller teats and tighter udders tend to result in fewer problems, breeders need to consider making breeding decisions to avoid extremes. In this context, while a higher EPD would lead to smaller teats and tighter udders over generations, caution is needed not to push the herd towards an undesirable extreme. A negative correlation exists between teat size and weaning weight direct (-0.14) and maternal (-0.17); this relationship is similar between udder suspension and weaning weight direct (-0.11) and maternal (-0.24). Weaning weight maternal is often referred to as the milk EPD and it is expressed as pounds of weaning weight.
Looking Ahead
The three research EPDs are planned to be released into weekly production EPDs during the annual updates that take place in late spring 2025. In addition, these three traits are undergoing research for inclusion in Maternal Weaned Calf Value ($M).
We take your genetic progress to heart.
That’s why we offer Cow Sense & Science – a blend of generational wisdom, phenotype, EPDs and genomics – to provide you with cattle that exhibit real‑world worthiness.
At GENEX, we appreciate cattle for their phenotype and know the importance of hard‑to‑measure traits. We believe that behind every good bull is an even better cow. At the same time, we must embrace today’s data‑backed technologies, utilizing EPDs and genomics to ensure our bull lineup is second‑to none.
At times, it may seem that Cow Sense & Science are at odds, but one without the other is not complete – because the whole that defines us is greater than the parts that make us. That is Cow Sense & Science.

Fertility: The Key to Unlocking Increased Profits
Breeding strategies vary from operation to operation, but there’s one critical question that directly impacts the profitability of every herd: How quickly can you get your cows pregnant?
Fertility is the foundation of a successful cow-calf operation. Every day a cow stays open costs money – whether from the missed opportunities of an earlier-born calf, lost potential of improved genetics or additional expenses of an extended breeding season. In a market where maximizing production is key to profitability, achieving earlier pregnancies is the first step toward improving efficiency – and putting more dollars in your pocket. Let’s break it down:
Earlier Calves = Bigger Calves.
A calf born earlier has more time to grow, resulting in weaning weights that can be 20 to 60 pounds heavier, directly translating to more revenue at sale time.
Fewer Days Open = More Efficient
Herd. The faster your cows are bred back means fewer open days, resulting in more productive cows per breeding season. This can dramatically reduce herd turnover and improve profitability.
Healthy Cows = More Pregnancies. Your mama cows are expected to calve early, breed back quickly, maintain body condition and raise big calves year after year. Keep them healthy and productive longer with sires proven to boost pregnancies.
The solution to improving pregnancy rates and profitability is simple. Use GENEX PregCheck™ fertility rankings to select bulls with superior fertility!
Data-Driven Results.
Based on millions of breeding observations gathered through GENEX’s on-farm database, PregCheck™ rankings offer the most accurate and reliable fertility data in the industry.
Proven Performance. The PregCheck™ ranking system is built on real-world data. It takes the guesswork out of sire selection and allows you to choose bulls with a higher probability of getting cows pregnant.
Financial Impact.
Using sires with superior semen fertility leads to better pregnancy rates, shorter calving intervals and higher weaning weights – all of which boost your profitability.
Fertility First, Profits Follow
Maximizing breeding success is about using the right genetics and tools that will pay off in both the short and long term. Choose sires with top PregCheck™ rankings to create a more efficient and profitable herd with greater overall returns.
PregCheck™ fertility rankings are set to a 100-base system, meaning the fertility rankings are calculated as an index with 100 being average. Every one-point difference above or below 100 represents a 1% difference in conception rate.

Driving Profitability & Innovation in Beef Production
In 2023, GENEX welcomed Leachman Cattle into our greater URUS family of ag companies. At Leachman Cattle, their philosophy centers on creating “cows that work and steers that pay.” Central to their approach is the $Profit® index—a comprehensive index that combines economic factors, genomic predictions and traits that are key to your bottom line.
How $Profit® Works
$Profit® assumes that the average commercial bull will have 100 progeny over its lifetime. The model assumes you keep 30% of your heifers as replacements and that you retain ownership on the remainder of the calves through finishing and sell on a grid. Maybe you are not a rancher who maintains ownership, but doesn’t it make the most sense to select from birth all the way to slaughter? Feedlots have already proven their willingness to pay premiums for superior calves. The model then factors in the effects on both income and expense to come up with a net profit figure for each bull.
$Profit® allows you to compare any two bulls and calculate the difference in profit that they are expected to generate in your herd. For example, let’s compare a $10,000 $Profit® bull to $6,000 $Profit® bull (the average for an Angus bull born in 2008). The predicted difference between these two bulls is $4,000 or about $40 per calf.
Traits Included in $Profit®
$Profit® includes nearly every trait that impacts profitability. The effect of most traits on profit is fairly simple to understand. Here is the list of what is included and its effect:
Revenue
Traits
• Calving Ease = more calves
• Weaning and Yearling EPD = more weight
• Cow Fertility = more calves at weaning
• Carcass Weight = worth more up to 1,050 lbs.
• Marbling = valued based on grid premiums
• Ribeye Area = valued as impacts yield grade
• % Retail Product = more yield is more meat
Cost Traits
• Cow Mature Size = in general, bigger cows eat more
• Cow Intake = more intake costs more
• Feedlot Feed Efficiency = cost of gain
Some traits are not so easily characterized for $Profit®. Milk, for example, is a good thing until you get too much. When over +25, milk EPD has more negative effect on fertility than it has a positive effect on weaning weight. There are a few traits not yet included in $Profit®: udder, structure and disposition. These traits are important but difficult to express in dollars.
Leachman Financial Indexes
There are two financial indexes that together make up $Profit®.
$Ranch®: Profit from birth through weaning.
Includes: fertility, milk, growth, cow feed intake and mature size
$Feeder®: Profit from weaning to harvest.
Includes: feed conversion, carcass value and carcass weight
$Profit®: Puts it all together into one number that predicts your bottom line! $Ranch® + $Feeder® = $Profit® % Rank

TERMINOLOGY
EPD: Expected Progeny Difference – The expected differences in performance of a sire’s progeny when compared to the average progeny of all sires evaluated within the breed. Based on actual performance, progeny performance and relatives’ performance.
ACC: Accuracy – The reliability placed on the EPD.
CE, CED: Calving Ease Direct – The difference in percentage of unassisted births, with a higher value indicating greater calving ease in first–calf heifers.
BW: Birth Weight – The birth weights of a bull’s progeny when compared to the breed average, in pounds.
WW: Weaning Weight – The adjusted weaning weights of a bull’s progeny when compared to the breed average, in pounds.
YW: Yearling Weight – The adjusted yearling weights of a bull’s progeny when compared to breed average, in pounds.
UDDR: Udder Suspension (Hereford, Charolais) – Differences in sire EPDs predict the difference expected in the sires’ daughters udder characteristics when managed in the same environment. Weak udder suspension results in pendulous udders that make it difficult for a calf to nurse.
TEAT: Teat Size (Hereford, Charolais) – Differences in sire EPDs predict the difference expected in the sires’ daughters udder characteristics when managed in the same environment. Oversized teats are difficult for newborn calves to nurse and the calf may not receive adequate colostrum.
DMI: Dry Matter Intake (Hereford) – Predicts the daily consumption of pounds of feed.
RADG: Residual Average Daily Gain (Angus) – The adjusted amount of post weaning gain in future progeny, in pounds, given a constant amount of feed consumed.
ADG: Average Daily Gain (Simmental) – The difference in pounds of daily gain expected between animals' progeny during the post weaning feeding period.
SCR, SC: Scrotal Circumference (Angus, Charolais, Hereford) – The adjusted yearling scrotal circumferences of a bull’s progeny when compared to breed average, in centimeters.
SCF: Sustained Cow Fertility (Hereford) – A prediction of a cow’s ability to continue to calve from three years of age through twelve years of age, given she calved as a two-year-old. Expressed as a deviation in the proportion of the ten-possible calvings to twelve years old expressed as a probability.
DOC: (Angus, Simmental) – The difference in yearling cattle temperament, with a higher value indicating more favorable docility.
CLAW: Claw Set (Angus) – Expressed in units of claw-set score, with a lower EPD being more favorable indicating a sire will produce progeny with more ideal claw set. The ideal target for claw set being toes are symmetrical, evenly and appropriately spaced.
ANGLE: Foot Angle (Angus) – 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 targeting animals with a 45-degree angle at the pastern joint with appropriate length and heel depth.
PAP: (Angus) – PAP is an indicator for animals with lower risk of developing high altitude disease. A lower PAP EPD predicts a sire should produce progeny with lower pulmonary arterial pressures, decreasing the risk of contracting high altitude disease, which is desirable.
HS: Hair Shedding (Angus) – An indicator trait for heat tolerance and tolerance to fescue toxicosis. 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 endophyte-infected (hot) fescue.
CETM, CEM, MCE: Calving Ease Total Maternal, Calving Ease Maternal, Maternal Calving Ease – The difference in percentage of unassisted births with a higher value indicating greater calving ease in first-calf daughters.
Milk, MM: Maternal Milk – The amount of pre–weaning performance gained by calves which can be attributed to the milking ability of a bull’s daughters, expressed in pounds of calf.
MTL, MWW: Total Maternal, Maternal Weaning Weight (Simmental, Charolais) – Measure of a sire’s ability to transmit milk production and growth rate through his daughters. Predicts the weaning weight of a sire’s daughters’ calves. Equal to his milk EPD plus half his WW EPD.
MG: Maternal Milk & Growth (Hereford) – The Milk EPD plus half the WW EPD. A sire’s M&G EPD reflects what he is expected to transmit to his daughters for a combination of growth genetics and maternal production.
ME: Maintenance Energy (Red Angus) – Differences in mature cow maintenance energy requirements. Expressed as megacalories per month.
HPG, HP: Heifer Pregnancy (Red Angus, Angus) – Differences in percent probability of female progeny conceiving to calve as 2-yearolds; a more accurate measurement than her sire’s or paternal brothers’ scrotal circumference.
MkH: Milking Herds (Angus) – Indicates the number of herds from which daughters are reported.
MkD: Milking Daughters (Angus) – Reflects the number of daughters having progeny weaning weight records included in the analysis.
MW: Mature Weight (Angus) – A predictor of the difference in mature weight of a sire’s daughters compared to the daughters of other sires, expressed in pounds.
MH: Mature Height (Angus) – A predictor of the difference in mature height of a sire’s daughters compared to daughters of other sires, expressed in inches.
STAY: Stayability (Red Angus, Simmental) – Differences in percent probability of daughters staying productive past the age of six.
CW: Carcass Weight – The adjusted carcass weights of a sire’s progeny, expressed in pounds.
MB, MARB, IMF: Marbling – A predictor of the difference in a sire’s progeny for percent marbling score or percent intramuscular fat in the ribeye muscle compared to other sires.
YG: Yield Grade (Simmental, Red Angus) – Expressed as a deviation of Yield Grade units where negative values are desirable.
REA, RE: Ribeye Area – Adjusted ribeye area of a sire’s progeny, measured in square inches.
FAT, BF: Back Fat – The adjusted twelfth rib fat thickness of a sire’s progeny, expressed in inches.
Carc H/P and Ult H/P: Group/progeny (Angus) – Reflects the number of contemporary groups and the number of carcass and ultrasound progeny included in the analysis.
I: Interim – The EPD is based on performance information of a bull’s sire, dam and relatives.
P: Pedigree estimate.
$EN: Cow Energy Value (Angus) – Assesses differences in cow energy requirements as an expected dollar savings difference in daughters of sires, expressed in dollar savings/cow/year. A larger value is more favorable when comparing two animals. $EN savings include lactation energy requirements and energy costs associated with differences in mature cow size.
$M: Maternal Weaned Calf Value (Angus) – Expressed in dollars per head, $M predicts profitability differences in progeny due to genetics from conception to weaning. $M is built off a self-replacing herd model where commercial cattlemen replace 25% of their breeding females in the first generation and 20% in subsequent generations. Remaining cull females and all male progeny are sold as feeder calves.
$W: Weaned Calf Value (Angus) – Provides the expected dollar-perhead difference in future progeny preweaning performance from birth to weaning, expressed in $/head. $W assumes producers retain 20% of their female progeny for replacements and sell the rest of their cull female and male progeny as feeder calves.
$F: Feedlot Value (Angus) – Calculates a $/head difference in expected progeny performance for post weaning merit. $F uses WW and YW EPDs along with trait inter-relationships. Typical feedlot gain value, feed consumption and cost differences are accounted for in the final calculations.
$G: Grid Value (Angus) – Combines quality grade and yield grade attributes, and is calculated for animals with carcass EPDs, ultrasound EPDs or both types of EPDs. A three-year rolling average is used to establish typical industry economic values for quality grade and yield grade schedules.
$B: Beef Value (Angus) – A terminal index representing the expected average dollar-per-carcass difference in the progeny postweaning performance and carcass value compared to progeny of other sires. This 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 quality-based carcass grid.
$C: Combined Value (Angus) – Expressed in $/head, $C includes all traits that make up both $M and $B with the objective that commercial producers will replace 20% of their breeding females per year with replacement heifers retained within their own herd. The remaining cull heifer and steer progeny are assumed to be sent to the feedlot where producers retain ownership of those cattle and will sell them on a quality-based carcass merit grid.
API: All–Purpose Index (Simmental) – Evaluates sires for use on the entire cow herd (bred to both Angus first-calf heifers and mature
cows) with daughters retained and remaining heifers and steers put on feed and sold grade and yield.
TI: Terminal Index (Simmental) – Evaluates sires for use on mature Angus cows with all offspring put on feed and sold on a grade and yield basis.
BMI$: Baldy Maternal Index (Hereford) – An index to maximize profit for commercial cow/calf producers who use Hereford bulls in rotational crossbreeding programs on Angus-based cows and heifers. Retained ownership of calves is assumed, with fed cattle marketed on a Certified Hereford Beef® (CHB) pricing grid.
BII$: Brahman Influence Index (Hereford) – This index is similar to BMI$, except Hereford bulls are used in rotational crossing with Brahman rather than Angus. Greater emphasis placed on traits deficient in Brahman-cross cattle, (fertility and age at puberty) and less on acceptable traits (growth and calving ease).
CHB$: Certified Hereford Beef Index (Hereford) – A terminal sire index where Hereford bulls are mated to British-cross cows and all offspring are sold as fed cattle on a CHB pricing grid.
ProS: (Red Angus) – The profitability and sustainability selection index is an all-purpose index that covers economically relevant traits across all aspects of the beef supply chain from conception to carcass. This updated index will be a combination of HerdBuilder, which includes traits from conception to weaning, and GridMaster, which includes postweaning through harvest traits. Expressed in $ per head born.
HB: HerdBuilder (Red Angus) – Used by producers to increase the sustainability of the cow herd and ultimately their operation. HB assumes bulls will be mated to both cows and heifers, replacement females will be retained within the herd, and the remaining progeny will be sold on a quality based carcass grid.
GM: GridMaster Index (Red Angus) – Used by producers whose primary goal is to maximize profitability of feeders in the feedyard and on the rail. GM assumes bulls will be mated to cows only, and all progeny will be sold on a quality based carcass grid.
TSI: Terminal Sire Index (Charolais) – Combines BW, WW, YW, REA, HCW, MARB and FAT into one single value. The TSI uses estimates of the genetic relationships between traits with an economic default value based on three year rolling USDA data.
PregCheck™ Rankings: An evaluation of an individual sire’s frozen semen conception rate. The model and data collection process is the first of its kind in the beef industry. PregCheck™ fertility rankings are not an evaluation of future fertility in a sire’s daughters.
Genetic Defects: In recent years several genetic defects have been identified, including Arthrogryposis Multiplex (AM), Neuropathic Hydrocephalus (NH), Contractural Arachnodactyly (CA), Developmental Duplication (DD), Osteopetrosis (OS) and Oculocutaneous Hypopigmentation (OH). It is important for A.I. companies to be vigilant concerning genetic defects as the opportunity to increase the frequency of these negative traits on the population can be significant. With bulls selling 50 to 100,000 units, a single carrier bull can widely spread a genetic problem. GENEX has worked hard to ensure this does not happen. All GENEX bulls listed in this directory have been tested or are known free by pedigree for the major genetic defects, unless otherwise stated.
