In regards to the article on the negative effect of using polled genetics on a herd's NM$ (Net Merit), I might suggest the investigators recalculate using the findings presented last year by John Cole of AIPL and Purdue University. That study showed polled animals carry a NM$ gain of $30 for reduced costs associated with dehorning. This calculation may one day be incorporated into the Net Merit formula.
