[QUOTE="Brandonm22, post: 640959, member: 7645"] Nobody ever suggested for a second that there aren't cattle out there with mediocre EPDs who don't have good phenotype. The genes for improving production (and/or improving phenotype) exist in the genetic diversity of most large populations of cattle whatever their current level of production as a group is. Likewise not ever production trait leader is the most pleasing animal too look at. EPDs are not about winning a ribbon they are about a statisticial system to measure production. You can use the numbers to increase the desired production traits. There is no reason (in theory) that your Murray Greys can't average 70 lb birth weights, 650 lb weaning weights, gain 4.2 lbs a day in the feed lot eating 9 lbs a day, and hang a 2 yield grade, high choice quality grade, 14.2" ribeye area carcass that is tender and tasty without losing that eye pleasing phenotype. To get there, you need to have some way to measure data for the traits that matter, and some way to measure the statistical probability that an animal possesses for thos traits. That is all the EPDs are. They are just a predictor of differences in progeny. [/QUOTE]
