[QUOTE="simme, post: 1850684, member: 40418"] It don't work that way. The epd numbers do not define a hard weight number. Actual weight is defined by environment (nutrition) as well as genetics (epd). The epd number is more about comparing two animal's expected performance in the same environment. Put a purebred angus calf on a dairy nurse cow and the actual weight at weaning will be way more than if the calf nursed his dam only. Independent of epd's. Put two angus calves on the same nurse cow - the one with the higher ww epd would be expected to weigh more at weaning, on average. Average weights will vary by herd, location, environment, management, etc. The epd's predict how animals will perform [B]relative to each other in the same environment[/B] - whether the average weaning weight is 350 # or 750 pounds in that environment.
