In other words, accuracy is an indicator of the reliability of an EPD. AGJA Board of Directors; AGJA Ambassador Program; … Individual animal EPDs are updated weekly by the BOLT powered genetic evaluation system. For example, a three year old bull with 90 calves would have EPDs of higher accuracy than a virgin yearling bull. The table below is a display of estimated progeny equivalents. GE EPDs affect two factors in this equation: accuracy of selection and generation interval. Fat (FT): Differences for fat thickness, in inches, for a carcass over the 12th rib, smaller numbers of fat thickness are preferable as excess fat can be detrimental to yield grade. EPD Definitions. The EPDs with an asterisk (*) next to the name are available to members only. A female’s genetics also influence the performance of her calves in the feedlot and at slaughter, so traits such as feed efficiency and carcass value are also included in $Cow. *Residual feed intake (RFI): Defined as the difference between an animal’s actual daily feed intake and its predicted daily intake based on growth rate and body size. 7:30 a.m.-4:00 p.m. CT, American Gelbvieh Association A higher value of this EPD is favorable, meaning that a higher percentage of a sire’s daughters get pregnant as first calf heifers compared to other sires in his contemporary group. Efficiency profit index (EPI): An economic selection index developed to aid producers in selecting for more feed efficient cattle that still have acceptable amounts of gain. Animals with a positive RFI value are deemed more inefficient because they consume more than expected while animals with a negative RFI value are considered more efficient because they consume less than expected. 1001 S. 70th Street Junior Classic; Regional Shows; The Summit; AGJA Contests. Beginning in 2011 with the inception on the Genomic Pioneers Project, the American Gelbvieh Association starting work toward yet another tool that made the EPDs produced in the NCE even more useful to producers. Listed below are the definitions of American Gelbvieh Association EPDs and the units in which they are published. Using this genomic enhanced information as a culling tool can help breeders decrease the generation interval in their herds, thereby speeding the rate of genetic change. $Cow will serve producers in selecting bulls that will sire daughters with stayability and reproductive efficiency as well as other traits that lead to profitability in a production system, such as milk, calving ease, moderate mature weight and the ability of calves to gain. FPI™ which stands for feeder profit index: An economic selection index designed to aid producers in selecting sires whose progeny will perform in the feedlot and are sold on a grade and yield standpoint. The stayability EPD is one of the best measures currently available to compare a bull’s ability to produce females with reproductive longevity. This information includes: individual performance, pedigree, progeny and grand progeny performance, plus available genomic information. This EPD is important to a rancher’s bottom line because it predicts which animals produce daughters with a genetic pre-disposition to calve unassisted as heifers. Confidence in an animal’s EPDs earlier in life means that producers can more reliably predict the performance outcomes of using unproven animals in their breeding herd. Guide to the American Gelbvieh Association Expected Progeny Differences (EPDs) Expected progeny differences (EPDs) can be used to predict the average performance of a bull’s offspring compared to other calves in their contemporary group (a contemporary group being calves that were born in the same calving season, in the same year, herd, sex, and were managed similarly). A negative, or lesser value, is more favorable. A higher number is favorable, meaning better calving ease. Yield grade (YG): Differences in yield grade score, which is a predictor of percent retail product. EPD estimates on an animal increase in accuracy over time as observations on an animal’s own performance and that of its descendants are added to the calculation. 30-month pregnancy (Pg30): Predicts the probability that a bull’s daughters will become pregnant and calve at three years of age, given that they calved as first-calf heifers. Yearling weight (YW): Predicts the expected difference, in pounds, for yearling weight (adjusted to a standard 365 days of age). Reducing risk by reducing possible change In an EPD listing, an accuracy number is often published below its corresponding EPD. Using GE EPDs can help your operation in three ways: Providing a high density genotype allows for increased accuracy in the EPD evaluation, just as an increase in the number of progeny and their performance data increases the EPD evaluation on a given sire or dam. As a terminal index, little emphasis is put on maternal traits such as stayability and calving ease. In these challenging times in the beef business, we know that Gelbvieh breeders are always looking for more tools to make their management decisions more efficient and accurate. For example, Bull A has a DMI EPD of .15 and Bull B has a DMI EPD of -.20, so the progeny of Bull B consume, on average, .35 pound less dry matter per day than progeny from Bull A. Just a few notes The American Gelbvieh Association first incorporated genomic information into the summer 2013 genetic evaluation. For example, if Bull A has a weaning weight EPD of 80, and Bull B in the same herd has a weaning weight EPD of 70, then bull A’s calves would be expected to be 10 pounds heavier at weaning than those of bull B. Van Eenennaam, A. AGA Gelbvieh Rules & Bylaws; Strategic Plan; State and Affiliate Associations; Foundation About the Foundation; Projects ; Board of Directors; History Book; Giving to the Foundation; Juniors AGJA Events. Greater marbling numbers are preferable and are an indicator of higher carcass quality grades. Marbling (MB): Predicts the differences in the degree of marbling within the ribeye as expressed in marbling score units. Marker Assisted Selection. Heifer pregnancy (HP): Predicts the probability that a bull’s daughters will become pregnant as first-calf heifers in a regular breeding season, expressed as a percent. AGA members are encouraged to call the AGA office at 303-465-2333 with any questions you may have regarding EPDs. Milk (Milk): The genetic ability of a sire’s daughters to produce milk expressed in pounds of weaning weight. Lincoln, NE 68510, ©2019 - American Gelbvieh Association | Managed by EDJE |, https://gelbvieh.org/wp/wp-content/uploads/2019/04/AGALogo1.png, Midwest Beef Cattle Consultants Education Seminar & Production Sale, Warner Beef Genetics ‘Genetic Opportunities’ Female Sale, Butler Creek Farm Power in the Blood V Online Female Sale, Chimney Butte Ranch Female Production Sale. Accuracy is improved by the number of records reported for an animal and with genomic information. Increasing accuracy Prentice Hall. Indexes are tools that allow producers to select for several EPDs at once, making selections more efficient than selecting on one trait at a time. GE EPDs help to reduce the amount of error between the difference in an animal’s true genetic merit and its predicted genetic merit (in other words, an EPD). Genomic Enhanced EPDs: Add Reliability to Your Tools for Genetic Improvement. The addition of genomic data to an EPD calculation is comparable to adding another source of information, like progeny or pedigree records. Possible change is another measure of accuracy that indicates the amount of future change in an EPD prediction (Bourdon, 2000). Increasing rate of genetic change Increasing rate of genetic change Accuracy is defined as the strength of the relationship between a prediction (EPD) and a sire’s true genetic value. References Lincoln, NE 68510, ©2019 - American Gelbvieh Association | Managed by EDJE |. Expected progeny differences (EPDs) can be used to predict the average performance of a bull’s offspring compared to other calves in their contemporary group (a contemporary group being calves that were born in the same calving season, in the same year, herd, sex, and were managed similarly). Suite 215 The EPDs with an asterisk (*) next to the name are available to members only. Greater ribeye areas are preferable. Phenotypes such as birth weight, weaning weight, and calving ease are still needed to make the equation we use to predict GE EPDs as accurate as possible. Breed Average EPD Value Breed Birth Weight Weaning Weight Yearling Weight Milk Akaushi 0.1 +26 +46 +27 Angus +1.2 +49 +87 +24 Beefmaster +0.5 +23 +42 +9 Black Hereford +2.8 +45 +76 +22 Braford +1.1 +14 +21 +4 Brahman +1.9 +17 +27 +6 Brangus +1.1 +26 +48 +9 Braunvieh +2.5 +44 +68 +35 Charolais +0.4 +27 +49 +9 Chianina +2.2 +40 +57 +16 Gelbvieh +0.5 +69 +100 +28 Hereford +323 … The combination of database information and genomic data resulted in EPDs that roll the accuracy of a DNA test and the information of individual, pedigree, and progeny performance into one, easy to use number. Increasing accuracy $Cow: Represents the genetic value in dollars of profit of an animal when retained as a replacement female relative to other animals in the herd. 1001 S. 70th Street Indexes are a good way to put selection emphasis on traits that are economically relevant. TM Index = MK EPD + ½ WW EPD. Total maternal (TM): An index that combines growth and milk information as a prediction of the weaning weight performance of calves from a sire’s daughters. For more information on GE EPDs, call the office at 303-465-2333. 4. generation interval. 1. Well ranking sires for FPI have higher marbling and carcass weight than their contemporaries. The rate of genetic change in an operation is dependent on four factors: All this information is combined into one easy to use number for selected traits that helps breeders make genetic improvement in their herd. Calving ease direct (CED): Percent of unassisted births of a bull’s calves when he is used on heifers. Lincoln, NE 68510, ©2019 - American Gelbvieh Association | Managed by EDJE |. We have already discussed how genomic data improves accuracy by adding another piece of information to EPD calculations. Listed below are the definitions of American Gelbvieh Association EPDs and the units in which they are published. The EPI provides slight negative pressure on intake, while keeping gain at a constant value. Understanding Animal Breeding. EPD breed averages updated four times a year. DNA information is also valuable because it can be collected at birth or soon after and added to an animal’s EPD calculation right away, which gives producers a better idea about that animal’s genetic merit at a younger age. Calving ease maternal (CEM): Represented as percent of unassisted births in a sire’s first-calving daughters. On young animals without individual or progeny performance records, genetic merit is estimated in the form of an EPD calculated by taking the average breeding value of its parents (VanEenennaam, 2009). By selecting on this index, producers will be able to find those animals that gain the same amount as their contemporaries while eating less. A higher number represents more favorable calving ease. *Average daily gain (ADG): Difference in average daily gain in pounds based on an animal’s performance during a feed intake test period. A higher number is favorable, meaning better calving ease. Braunvieh +2.8 +39 +62 +33 Charolais +0.5 +26 +46 +8 Chianina +3.7 +38 +71 +10 Gelbvieh +0.8 +64 +93 +28 Hereford +3.5 +46 +76 +19 Limousin +1.7 +46 +83 +23 MaineAnjou +1.7 … Maternal traits. This being said, an EPD is by far the most reliable indicator of an animal’s genetic merit due to the amount of information incorporated into the calculation. 7:30 a.m.-4:00 p.m. CT, American Gelbvieh Association Suite 215 A higher number represents more profitable genetics for maternal productivity. 2009. This results in an EPD with a low accuracy calculation. 3. Below you will find this information from their website, www.gelbvieh.org.
