[QUOTE="robert, post: 819761, member: 9171"] $EN is an index I personally have no use for, it is only a measure of input, it's like saying your gas tank holds 10 gallons, how many miles can you go with that? no fricking clue! Could be 100, 500 or somewhere in the middle, it has proven to be a useful bragging tool for zero growth, zero milk cattle though.... If any of the $indexes are worth a hoot in the real world then $W comes closest, it contrasts inputs ($EN) with output (growth to weaning) to create a balance. I know from my own herd records if I rank my cows on $EN the least productive, least milky cows rise to the top, if I rank on $W you will pretty well see the Pathfinders and everything else after that.
