Just always remember that the E in EPD stands for estimated. Theoretically, they help you sort out each individual's genetic potential, but ultimately differences in environment and management and how they mesh with the genetics you already have mean there are big differences in the effect they have on your herd vs how they look on paper. EPD's are a tool that can be very useful in making a final decision, but always look at phenotype first. If you have enough cattle to sell uniform pot loads of calves at a time, you might get a little premium for good growth or carcass epd's (or maternals for a load of females), or it might matter if you're selling them one at a time private treaty or in your own or a special consignment sale. But if you're taking a few or even a gooseneck load or two to a sale barn, like most of us do, phenotype is what sells most calves for most people.
