[QUOTE="Aero, post: 255335, member: 2076"] Scotty: ET calves can be factored in if out of a registered recip. the basic process is: 1. average out the parental EPDs (BW EPD: 3.9 + -.2 = 3.7 / 2 = [b]+1.9[/b]) Accuracy will be .05 2. if the calf has a high or low ratio, the EPD will move that direction (he must have ratioed pretty low for birth weight, so his EPD came down quite a bit to [b]+.3[/b] Accuracy will be in the .25 - .36 range unless he is an ET calf out of a comm recip 3. with his first calf crop, the ratio of his calf crop compared to others will move his EPDs up or down. 50 calves will get Acc up to .50 - .70 *this isnt very precise and there are some other small factors, but it is basically right [/QUOTE]
