[QUOTE="dun, post: 30775, member: 34"] I don't have all of the stuff anymore but it was the UofNM, OKSU, and a couple of other universities. The way the arrived at this was over a number of years. The straightbred calves from straighbred cows were compared to crossbred calves from straighbred cows, and straightbred calves from crossbred cows and crossbred calves from crossbred cows were used. I saw the article a couple of months ago in the Midwest Cattleman. I'm just curious how they got straighbred calves from crossbred calves without using ET which would skew BWs. Basicly all calves from crossbred calves were heavier at weaning then those from straighbreds. And crossbred calves outweighed the straighbred calves. dun [/QUOTE]
