Expected Progeny Differences ‘EPD’ Definitions The American Gelbvieh Association transitioned to the BOLT system for EPD calculations in the fall of 2018. The American Angus Association had already been using this system for the previous year. There are 12 beef breed Associations in collaboration to form IGS (International Genetic Solutions) which brings a new, streamlined method for incorporating genomic results into the EPDs. This incorporates data and updates EPDs on a weekly basis. EPD Definitions: CE : Calving Ease – A number that predicts the average difference in ease with which a sire’s calves will be born when he is bred to first calf heifers – higher numbers indicate greater calving-ease . BW : Birth Weight, WW : Weaning Weight & YW : Yearling Weight – All are expressed in pounds, this shows the expected number of pounds a bull or female will add or subtract from their progeny’s birthweight, weaning weight and yearling weight respectively. MK : Milk: expressed in pounds of weaning weight that a female will add/subtract or that a bull’s daughters will have. CM : Calving Ease Maternal: this EPD predicts how well an animal’s daughters will calve with a higher number being easier calving. NEW! MW : Mature Weight: Body weight of cows adjusted to six years of age at body condition score 5. MWT is reported in pounds and is computed from a genetic model that leverages information from weaning weight, post-weaning gain, and mature weights of cows. Reported weights are adjusted for both age at observation and for body condition. ST : Stayability: Predicts the genetic difference, in terms of percent probability, that a bull’s daughters will stay productive within a herd to at least six year of age. DOC : is expressed as a difference in yearling cattle temperament, with a higher value indicating more favorable docility. It predicts the average difference of progeny from a sire in comparison with another sire’s calves. In herds where temperament problems are not an issue, this expected difference would not be realized. RE : Rib Eye Area: expressed in square inches of rib eye muscle area adjusted to a constant fat endpoint. MB : Marbling: expressed in degrees of marbling score, a determinant of USDA Quality Grade. Value is adjusted to a constant fat endpoint. MPI, FPI, TPI: SEE INDEX DEFINITIONS ON FACING PAGE NEW! $G : $GAIN: reports the difference in expected marginal value of gain less the cost of feed to achieve that gain. Reported in dollars of marginal profit with more positive values representing increased efficiency and profit.
