3. Introduction Large variation in carcass quality Challenge to meet consumer demand, especially in small businesses that can not “sort” Cow/calf producers do not have access to data on the carcass quality or retail value of their beef. Objective: Determine which carcass measurements affect retail value

4. Procedures Cattle fed and slaughtered at Wilson Beef Farms, Canaseraga, NY Feeder calves on feed ~700 lb. Corn silage, corn, soybean meal ration Formulated 2.5-3.0 lb. ADG 4-6 head/wk slaughtered (6 miles from feedlot)

5. Procedures Carcasses chilled 7 or 14 days Carcass data collected every 2 weeks: HCW, BF, REA, Marbling, KPH Two sides are processed into retail cuts Developed regression equation to predict Total Retail Value.

8. Results Based on the current data and statistical analysis, the results can be summarized by the following regression equation (101 observations). Total Retail Value (side) = -23.93 + 1.67*HCW - 120.03*BF - 22.43*KPH + 8.62*REA HCW For every pound increase in HCW, Retail Value increases $3.34 BF For every inch increase in BF, Retail Value decreases $240.06 REA For every square inch increase in REA, Retail Value increases $17.24 KPH For every percent increase in KPH, Retail Value decreases $44.86
