[QUOTE="Brandonm2, post: 156379, member: 2095"] EPDs are the "expected" progeny differences. It does not say that every calf out of a bull is going to weigh 75 pounds. A proven low birthweight Angus bull could still throw a 110 pound calf and a high birthweight Charolais bull could throw a 70 pound calf; that is just not what we would expect based on their history. Obviously a mature large framed cow on a high plane of nutrition in mild weather is going to be more likely to throw a high birthweight calf than a 22 month old Jersey heifer eating poor hay with a hurricane hitting at 275 days into the gestation even if that does not gibe with the EPD data.
