What’s a Milk EPD Worth?
Mike Baker, Beef Cattle Extension Specialist, Cornell University
Use of Expected Progeny Differences (EPD’s) is a useful tool in increasing the genetic merit of the cow/calf operation. A sire’s milk EPD is the measure of the expected increase in calf weaning weight that can be expected out of his daughters due to an increase in milk production. A study was conducted in Oklahoma to determine the actual increase in milk production and weaning weight observed when using sires with high and low milk EPD’s.
