Sale Information ProS – Profitability and Sustainability is an all-purpose index that predicts average economic differences in all segments in the beef supply chain. This index is a combination of the breeding objectives modeled in the HerdBuilder and GridMaster selection indexes. In this index, replacement heifers are retained from within the herd and all remaining progeny are fed out to slaughter and sold on a quality-based grid. Traits included in this index include CED, ADG, HPG, STAY, MW, DMI, CW, MARB, REA and Fat. Index | Dollars per Head | Higher Value
Red Angus Guide to EPDS and Indexes
GM – GridMaster is a selection index that predicts the average economic difference of non-replacement calves through the post-weaning phase of production. GM places selection pressure on growth, feed yard performance and carcass traits. GM is calculated based on the scenario that progeny are fed out to slaughter and marketed on a quality-based carcass grid. This index is a combination of ADG, CW, DMI, MARB, Fat and REA. Index | Dollars per Head | Higher Value
HB – HerdBuilder is a maternal selection index that predicts the economic differences of animals for traits that are important from conception through weaning. HB is calculated based on the scenario that bulls are mated to heifers and cows, replacement heifers are retained and all remaining progeny are marketed at weaning. This index is a combination of CED, CEM, WW, Milk, MW, HPG and STAY. Index | Dollars per Head | Higher Value
CED – Calving Ease Direct predicts differences in the percent of calves born unassisted out of 2-year-old dams. Percent | Higher Value BW – Birth Weight predicts differences in actual birth weight of progeny. Pounds | Lower Value WW – Weaning Weight predicts differences in 205-day weaning weight. Pounds | Higher Value YW – Yearling Weight predicts differences in 365-day yearling weight. Pounds | Higher Value ADG – Average Daily Gain predicts differences in weight gain between 205 and 365 days of age. Pounds | Higher Value DMI – Dry Matter Intake predicts differences in daily feed intake as measured in a feedlot during the post-weaning period. Pounds | Lower Value MILK – Milk predicts differences in weaning weight attributed to the milking ability of the animal’s daughters. Pounds | Higher Value ME – Maintenance Energy predicts the difference in maintence energy requirements. Mcals per Month | Lower Value HPG – Heifer Pregnancy predicts differences in the percent of daughters who are able to conceive and calve at 2 years of age following exposure to breeding. Percent | Higher Value
CEM – Calving Ease Maternal predicts differences in the percent of daughters who are able to calve unassisted as 2-year-old heifers. Percent | Higher Value STAY – Stayability predicts differences in the ability of an animals’ retained daughters to remain productive in the herd – calve every year – through 6 years of age. Percent | Higher Value MARB – Marbling predicts differences in marbling score – amount of intramuscular fat measured at the 13th rib. Marbling Score Units | Higher Value YG – Yield Grade predicts differences in USDA Yield Grade, which is calculated using CW, REA and Fat. Yield Grade Units | Lower Value CW – Carcass Weight predicts differences in actual hot carcass weight. Pounds | Higher Value REA – Ribeye Area predicts differences in square inches of ribeye area measured at the 13th rib. Square Inches | Higher Value FAT – Fat predicts differences in the depth of backfat measured between the 12th and 13th ribs. Inches | Lower Value
