[QUOTE="smnherf, post: 818200, member: 3235"] I think that calculateing ADG based on adjusted 205 day weights and adjusted YW is a dangerous game that may very well lead to false conclusions. If the animal was weighed at 250 days, and on poor feed, his adj WW may have been adjusted down considerably from what it actually was. The way the formula is calculated, younger animals tend to get adjusted up more than what they actually gain whereas the older animal gets punished for not gaining as much as the formula thinks they should have gained. Same way on yearling data. Most guys who want to brag about their adj WW push them hard and then weigh them as young as possible. The AI company apparently has confidence in the data or they wouldn't have made the purchase. I am not saying that I agree with everything that AI companies do. [/QUOTE]
