Most breeds use a fixed base. This means that the breed average EPD changes from year to year. Put simply, a positive EPD doesn't always mean above average. Be aware of what the current breed average EPD is for each trait. Current EPD values for a number of breeds are shown in the table.
Most breeds update their EPDs twice per year.
Comparing Enigma's EPDs to the breed average is very informative. He is near the breed average for birth weight, milk and weaning weight, but is far below average for yearling weight. Average or below average EPDs are not necessarily bad . This is a moderate bull, and will likely produce moderate sized replacement cows that do not have excessive feed requirements. But he is probably not an ideal terminal sire due to his below average yearling weight.
