[QUOTE="Katpau, post: 1258273, member: 9933"] I was actually referring to CED, which is an estimate of the calving ease of his own direct offspring. CEM is the ease with which his daughters give birth. That is a very important number if you plan to keep daughters. I have never used 7229 and had not noticed his CEM had dropped. I see his CED is +4 today and his CEM is only a +3. and has an 81% accuracy. Apparently the data reported indicated that more of his heifer daughters required some assistance calving. The breed average CEM is between +8 and +9. I consider CEM much more important than CED when using a bull in hopes of getting replacements. A CED of +4 should be perfectly fine to use on cows and even most heifers. Most of us keep an eye on the heifers anyway. It is usually necessary to give up a little BW in order to get good growth and most older cows can handle more size and birth weight, so they don't need an extreme calving ease bull. The CEM of +3 tells me I might have more than average amounts of dystocia on his daughters. Why bring in that trouble? Black Granites CEM is +13 right now with a 19% accuracy. It is based on his two genetic profiles, and his parents numbers. I hope the numbers are right, because in a couple of years I plan to be calving out my own Black Granite daughter. [/QUOTE]
