RED ANGUS GUIDE TO EPDS

RedAngus.org

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 calving ease, growth, HPG, STAY, Mature Weight, Dry Matter Intake and carcass traits. The resulting index is expressed in dollars per head born (Index/High Value).

HB ....... HerdBuilder is a maternal selection index that predicts the economic differences of animals for traits that are important from conception through weaning. Expressed as dollars per head born, 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. Traits included in the HB index include Calving Ease Direct, Calving Ease Maternal, Weaning Weight, Milk, Mature Weight, Heifer Pregnancy and Stayability (Index/High Value).

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, feedyard performance and carcass traits. Expressed as dollars per head born, GM is calculated based on the scenario that progeny are fed out to slaughter and marketed on a quality-based carcass grid. Traits included in GM include Average Daily Gain, Carcass Weight, Dry Matter Intake, Marbling, Back Fat and Rib Eye Area (Index/High Value).

CED ........ Calving Ease Direct predicts differences in the percent of calves born unassisted out of 2-year-old dams. (Percent/High Value)

BW Birth Weight predicts differences in actual birth weight of progeny. (Pounds/Low Value)

WW Weaning Weight predicts differences in 205-day weaning weight. (Pounds/High Value)

Andy Albrecht • (402) 922-1000 • andy@topdollarangus.com

YW Yearling Weight predicts differences in 365-day yearling weight. (Pounds/High Value)

ADG ....... Average Daily Gain predicts differences in weight gain between 205 and 365 days of age. (Pounds/High Value)

DMI ....... Dry Matter Intake predicts differences in daily feed intake as measured in a feedlot during the post-weaning period. (Pounds/Low Value)

MILK Milk predicts differences in weaning weight attributed to the milking ability of the animal’s daughters. (Pounds/High Value)

ME Maintenance Energy predicts the difference in maintence energy requirements. (Mcal per Month/Low 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/High Value)

CEM ...... Calving Ease Maternal predicts differences in the percent of daughters who are able to calve unassisted as 2-year-old heifers. (Percent/High 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/High Value)

MARB Marbling predicts differences in marbling score – amount of intramuscular fat measured at the 13th rib. (Marbling Score Units/High Value)

YG ......... Yield Grade predicts differences in USDA Yield Grade, which is calculated using CW, REA and Fat. (Yield Grade Units/Low Value)

CW Carcass Weight predicts differences in actual hot carcass weight. (Pounds/High Value)

REA Ribeye Area predicts differences in square inches of ribeye area measured at the 13th rib.(Square Inches/High Value)

FAT Fat predicts differences in the depth of backfat measured between the 12th and 13th ribs. (Inches/Low Value)

SELLING 15 commercial open yearling heifers after the bulls.

NOTES:

Laso Red River Z128h

We selected Red River from Lautenschlager and Sons Red Angus in their 2021 Red Bull rendezvous. As thick of a Red Angus bull as I have seen anywhere. He scanned an impressive 6.13 IMF ratio 108, 13.59 REA ratio100, at 1206 lb. An upper end growth bull without a huge frame he fills all of the spaces with muscle. A flushmate sister sold at the 2020 Bet on Red sale for $16,000.

Knowing he was not a caving ease bull we put him on 2-year-old heifers and had very good success calving. We have since noticed he makes a tremendous combination with our Simmental cross cows. Let’s not overlook the maternal power in this sire as well. The Dory Jiba Cow line goes back to Leachman breeding from the early days when they produced tremendous herd Bulls. The dam is well balanced with a deep rib and capacity, very well formed udder with excellent feet and legs.

Sire to Lots 1-6x.

Geonomically Enhanced EPD’s

Each Bull has a blood sample collected at weaning time, which is sent to the DNA lab for evaluation. Markers on each individual trait for each bull are identified which in turn are entered into the red angus data base and will add to the accuracy of each individual EPD for each animal. The result, (Genomic enhanced EPDs) increases the bulls EPD accuracies to the point as if they had sired a calf crop. The lab also does a parentage test which identifies the sire and dam precisely. Any potential genetic defects are also ruled out.

Sons Of Laso Red River Z128h

Wood Selway 2321

Lot 1, The first of our Red River Sons is a top gaining, moderate frame, calving ease bull with excellent carcass scan. His dam is a dark red, moderate framed, deep-bodied, beautifully uddered, 76C daughter. High ratios in IMF with top 11% Marbling and 7% Ribeye EPD’s. The overall genetic package in this Bull will bring as much profitability to your calf crop and your future cowherd has any bull in the country. Marbling and ribeye area are antagonistic traits. We have a combination here in this breeding that excels in both without sacrificing maternal traits, fleshing ability, moderate frame size, and pounds of calf weaned, which translates to overall productivity for a given ranch land carrying capacity. The dam combines two of the most productive cow family’s in the breed, Osce and Rebalas. Her CED is 21 top 1% with -3 ME top 19.

Wood Lochsa 2345

Lot 2, 2345 is a 1/4 Simm bull with excellent carcass numbers for both Ribeye and Marbling. Good calving ease and maternal strength here. Dam is a larger frame, deep-bodied, beautifully uttered simm/angus. Highest Ribeye EPD in the sale, top 1%, highest ADG at 100 days on test.

Another highperforming Dunn Infusion A526 daughter exhibiting the same characteristics. I have yet to see a poor quality phenotype in an Infusion daughter. Her own EPD profile includes a top 22% ProS, top 17% HB, top 14% CED top 12% Stay, top 15% Marbling, actual birth weight 68 lb. Her maternal Grand sire was the high maternal, calving ease, carcass bull Lorenzen Julian 7811.
