Expected progeny differences (EPD) are an evaluation of an animal’s genetic worth as a parent. They are based on animal models which combine all information known about an individual and its relatives to create a genetic profile of the animal’s merits. These profiles are then compared to other individuals of the same … See more An example of a set of EPDs looks like the following chart. Each set of letters stands for a specific measurement with an accuracy reading and percent rank below it. Each EPD is compared to the breed average of … See more EPDs are used in both scientific research and in typical farm usage. Through mathematical equations and computing power EPDs can … See more WebThe difference in the birth weight EPD value between Bull A and Bull B is 4 pounds (5 - 1 = 4). Therefore, Bull A would be expected to sire calves that average 4 pounds heavier at birth than calves sired by Bull B. It is important to recognize that EPDs predict the expected difference in performance, not the actual performance. WebExpected progeny differences are useful in comparing or ranking individ uals within a breed for traits of interest. They also are a prediction of future progeny performance for a specific trait of one individual com pared to another individual. Thus, it is the differences in EPDs that are informative. bpi talents
