Brown V Board Of Education EPD’s Expected progeny differences are valuable tools for use in replacement bull and female selection. EPD’s can and should be used by purebred and commercial cattlemen alike since research has shown that they represent the most effective means to make progress through selection. An EPD is an estimate of what a bull or cow will transmit to their opffspring. They are calculated by breed associations for any animal that has sufficient performance data. The breed associations use pedigree information, the animal’s own performance, and eventually progeny data to calculate EPD’s. EPD’s are calculated for several traits including birth weight BW, weaning weight WW, yearling weight YW, Milking ability MA, total maternal, direct calving ease, hip height, scrotal circumference, ribeye area, fat thickness and marbeling. BW, WW, YW, and MA, the other traits are reported only by some breeds. For growth traits, EPD’s are expressed in pounds of live weight, epd’s, weight, traits, epd, data, carcass, breed, yw, ww, ultrasound, selection, ribeye, progeny, performance, means, ma, fat, expressed, express, estimate, effective, ease, calving, calculated, bw, bull, birth, been, associations, area, yearling, weights, weaning, way, very
