[QUOTE="CattleMan1920, post: 1562067, member: 37967"] I've always noticed that animals we have in the herd with high $B values are significantly heavier at weaning than those in the lower percentile. There is an ancillary effect of a high $B animal. I cannot exactly explain why, but I've never seen big weaning weights off of the extreme $EN, DMI animals, with low percentile $B numbers. They are almost always in the 500 range no matter how much you throw at them as far as inputs. I've tested this theory with Stone Gate bulls, versus AI bulls. The AI bulls blow past 500 well before their 205 weighing. You can argue this all you want with me, but I have done the comparisons and I have seen it with my own two eyes. I've never had a son from a high CED, very high DMI and $EN, low birthweight bull ever top 700 at weaning. If others have that is great. My AI sons from SAV are a whole different ballgame, however. Here is an exact explanation from Angus, do with it what you will. [color=#0000FF]Beef Value ($B) facilitates what almost every beef breeder is already seeking - simultaneous multi-trait genetic selection for feedlot and carcass merit, based on dollars and cents. $B represents the expected average dollar-per-head difference in the progeny postweaning performance and carcass value compared to progeny of other sires. The $B value is comprised of two pieces: $F and $G. To align $B with marketplace realities and appropriately value carcass weight in Angus cattle, the following factors are incorporated into the final calculations for $B. $B is not simply the sum of $F and $G. Projected carcass weight and its value are calculated, along with production cost differences. $B takes into consideration any discount for heavyweight carcasses. Final adjustments are made to prevent double-counting weight between feedlot and carcass segments. The resulting $B value is not designed to be driven by one factor, such as quality, red meat yield or weight. Instead, it is a dynamic result of the application of commercial market values to Angus genetics for both feedlot and carcass merit. [/color] [/QUOTE]
