geny are sold as feeder calves. Increased selection pressure on $M aims to decrease overall mature cow size and improve t structure and fertility while maintaining weaning weights consistent with today’s production. aned Calf Value ($W) , an index expressed in dollars per head, provides the expected difference in future progeny weaning performance from birth to weaning. $W assumes that producers retain 20% of their female progeny for lacements and sell the rest of their cull female and male progeny as feeder calves. Over time, increased selection pressure $W will increase weaning and maternal milk traits while also continuing to increase mature cow size. What are $Value Indexes?
You are not alone if you find it overwhelming to understand all the EPDs in the angus breed. A helpful tool that simplifies the process are the $Value Indexes. The $Value Indexes summarize EPDs into categories. See the adjacent chart to find the $Value Index that contains the highest number of EPDs that are important to your selection process, and use that Index as another tool for making your decisions. For a more detailed explanation of the $Value Indexes, go to angus.org. mbined Value ($C) , an index expressed in dollars per ad, includes all traits that make up both $M and $B with the ective that commercial producers will replace 20% of their eding females per year with replacement heifers retained hin their own herd. The remaining cull heifer and steer geny are then assumed to be sent to the feedlot where the ducers retain ownership of those cattle and eventually sell m on a quality-based carcass merit grid. edlot Value ($F) , an index expressed in dollars per head, is expected average difference in future progeny performance post-weaning merit compared to progeny of other sires. The derlying objective assumes commercial producers will retain nership of cattle through the feedlot phase and sell fed cattle a carcass weight basis with no considerations of premiums discounts for quality and yield grade. d Value ($G) , an index expressed in dollars per carcass, is expected average difference in future progeny performance carcass grid merit, including quality and yield grade ibutes, compared to progeny of other sires. ef Value ($B) , an index expressed in dollars per carcass, ilitates simultaneous multi-trait genetic selection for feedlot d carcass merit. $B represents the expected average erences in the progeny postweaning performance and cass value compared to progeny of other sires. This index umes commercial producers wean all male and female geny, retain ownership of these animals through the feedlot ase and market these animals on a quality-based carcass d.
