I think I get hurt with birth weights with small contempory groups. Older cows in small groups with higher birthweights get crucified as well.jscunn said:I figured someone would have commented about the BW Ratios. This is a real slick cow in the summer time, I think that usually ends up adding some BW because she will be out eating when some of the others are still in the shade. the actual weights are weighed with a scale not a tape and they aren't terrible, well maybe 90# out of a heifer is a bit much, but she had it without help..
