Some bulls make the cut or miss the cut based on a combination of traits.
105's calving ease is just barely better theb breed average, for heifers I want a much better calving ease number, plus based on his evaluations, to much height, poorfeet and large teats. That pretty much eliminates him from using him for anything. MMD misses becauseo f his calving ease, height, CETM is a big killer and muscle. That makes him a throw away as far as I'm concerned.
For heifers I want CED of at least double the breed average, that usually puts them in the minus 3-5 range for BW.
If there is no way I would keep a heifer out of a particular cow I would use Cherokee Canyon again. We're really impressed by the growth, calving ease adn the vigor of the new born calves. We'll find out about carcass in a couple of months when all of his calves from last year get slaughtered, both bulls and heifers.
We're willing to give up a little in milk and some other maternal type traits if the bull has really impressive carcass AND calving ease. We're willing to give up some weight o get better carcass as long as the calving ease is there. The deal for us is, there are bulls that will provide a well balanced calf and provide the required calving ease. It all depends on what is needed, what is planned to be done with the calves, but for heifers, calving ease (CED) is paramount.
Stayability is important but unless we really plan on keeping heifers it's pretty much a moot point.
We also have available Select Sires, Genex and ABS, so we have a really good selection of bulls to choose from.
We have one Millenium daughter. Definitely not a heifer bull, but boy does she calf easy, and unfortunetly milks way too heavy. The standard joke before we wean her calf is that she's a solid red Holstein. That's the kind of body condition she carries. But she breeds back first service and after weaning she'll gain 50-75 pounds in a matter of a couple of weeks. Darn nice cow, but not an easy keeper.
Sorry, done babbling now

Dun & others --- this discussion has interested me, and I'd like to ask a few questions if I may. I've never paid much attention to many of the EPD figures due to the type of little operation I have, so these may be stupid questions and/or observations. I know a lot of times you folks select certain bulls for matings with certain cows to try to improve or correct on specific traits and physiology --- but let's say on a superficial basis if I'm just looking at the EPD figures for the Genex possible "heifer bulls" other than Chateau, Dynamics and Vacation:
Would you exclude "Make My Day" mainly because of lousy ribeye figures and despite what appears to be very good marbling figure? Or because his WW and YW are a tad low even for a heifer bull? And he has low "Stayability"? I never have seen Stayability EPD discussed much, so maybe you guys place little importance on it?
And JR 105 might be a heifer bull as to birth weight EPD but he has poor milk and total maternal, lower growth and stayability along with poor carcass? Were it not for low birthweight EPD why would anybody even consider using him?
Thanks for any thoughts you care to share.. Arnold Ziffle
