[QUOTE="bigag03, post: 677537, member: 9247"] Cypress, You cannot use the across breed EPD table to make broad statements as you are doing. If you used [b]A[/b] Hereford bull whose WW EPD were 0 and [b]A[/b] Charolais bull whose WW EPD were 0 on similar cows of a third breed type (you have to eliminate heterosis inconsistencies, i.e. if you used these bulls on Hereford cows the comparison means nothing because the Hereford sired calves would have no heterosis while the calves sired by the Charolais bull would exhibit 100% hybrid vigor), then you would expect the Charolais sired calves to average 41 lbs heavier at weaning. This does NOT mean that Charolais sired calves outweigh Hereford sired calves at weaning by 41 lbs. As to the color, provided your cows are homozygous black, all calves should be light smokey. There will be some variation from off-white to almost black, but the whole should be smokey. [/QUOTE]
