Accuracy Matters...
because not all EPDs are created equal! Mushrush Red Angus spends a lot of time and money ensuring that the EPDs we publish on our cattle are the most accurate possible. We do this by reporting “All the Data, All the Time”. This investment in accuracy is part of our commitment to our customers – so you can make the genetic progress you desire, without unpleasant surprises. For more than 20 years, the Red Angus Association of America (RAAA) has mandated Total Herd Reporting (THR), which requires annual reporting of each registered Red Angus cow’s production (or lack thereof). RAAA has also required weaning weights/dates as a registration requirement since 1954. That works for weaning weight (WW) and stayability EPDs (STAY). However, data specific to other traits is reported at each breeder’s option and expense. Due to pedigree relationships, most animals get EPDs printed for almost every trait – even when the seedstock provider hasn’t collected data for those traits. They still get to market animals with EPDs because principled breeders with related animals have collected data. When animals are registered to a known sire and dam, EPDs (albeit relatively low accuracy EPDs) are calculated. Breeders who go to the trouble to collect and submit phenotypic data (birthweights, calving ease scores, heifer pregnancy observations, ultrasound data, etc.) will further increase the accuracy of those animals’ EPDs. The magnitude of such increases in EPD accuracy is limited by the heritability of the trait and the quality of the data. More meaningful data comes when phenotypic observations are collected in accurately reported contemporary groups (CG) where all animals in it have an equal opportunity to perform. Further increases in accuracy of even yearling bulls are possible when breeders supplement pedigree and performance data with genomic data. Genomics impact the EPD and associated accuracy similar to additional progeny data. For many traits, genomic data will impact the EPDs and accuracy as much as the bull’s first natural service calf crop. It’s important to understand that more data doesn’t necessarily make the EPD more desirable; it does make the EPD more accurate. Meaning that as additional data is added, the published EPD gets closer to the animal’s true genetic merit. This is demonstrated in Table 1 using the examples of Calving Ease and Marbling.
One advantage of Genomic Data is that a single hair/blood sample can provide data and accuracy increases for up to 13 traits. However, genomics doesn’t eliminate the need for phenotypic data – which is needed to calibrate the genomic panels. Or, as Dr. Daniela Lourenco, UGA said at the 2017 BIF Conference, “Genotype without phenotype is like having a credit card but no money to pay it off at the end of the month.”

Bull A – represents a bull with only pedigree information plus required RAAA performance data Bull B – has everything Bull A has, plus at least a birth weight, calving ease score, and IMF scan (all taken within meaningful contemporary group) Bull C – has everything bull B has plus genomic data (RA50K)
We collect the following data that is used in the calculation of Red Angus EPDs and economic indices: + Birth weight + Calving Ease Score + Weaning Weight +ADG + Cow Weight & Body Condition Score + Heifer Pregnancy Observations + Stayability Observations + Ultrasound measure for %IMF, REA, and Fat thickness We further enhance the EPD accuracy for the above traits by investing in genomic data for every bull we sell. Our carcass EPDs are augmented by annual structured progeny tests, where we work with ranch and feedlot partners to collect actual harvest data on progeny of the same Mushrush reference sires that are represented in our bull sale. Additionally, we collect field data that is not currently used in EPD calculation but soon may be. This includes Dry Matter Intake (DMI), Feed Conversion (F:G), and Udder Scores While animals that falter in the above traits won’t have that reflected in an EPD – we will eliminate them from the herd, so our customers never have a chance to own them or their progeny.
If we seem a bit obsessive about “All the Data – All the Time”, we’ll take that as a compliment. We do it so our customers will be able to make the best-informed genetic investment decisions possible.
