Factors affecting the selling price of feeder cattle sold at Arkansas livestock auctions in 2005.

Data were collected from 15 Arkansas livestock auctions to determine factors affecting selling price. Data included how calves were sold (single or groups), sex, breed or breed type, color, muscle thickness, horn status, frame score, fill, body condition, age, health, BW, and price. Data were randomly collected on 52,401 lots consisting of 105,542 calves. Selling prices for steers ($124.20 +/- 0.07), bulls ($117.93 +/- 0.12), and heifers ($112.81 +/- 0.07) were different from each other (P <0.001). Hereford x Charolais feeder calves sold for the highest price ($122.66 +/- 0.14) and Longhorns sold for the lowest price ($74.52 +/- 0.46). Yellow feeder cattle received the highest selling price ($96.47 +/- 0.12), and spotted or striped feeder cattle received the lowest price ($83.84 +/- 0.23). The selling price of singles was lower than the price for calves sold in groups of 6 or more ($117.26 +/- 0.06 vs. $122.61 +/- 0.21; P <0.001). For cattle classified as having muscle scores of 1, 2, 3, and 4, selling prices were $120.45 +/- 0.05, $111.31 +/- 0.09, $96.28 +/- 0.44, and $82.21 +/- 1.87, respectively. Polled feeder cattle sold for $118.57 +/- 0.05, and horned feeder cattle sold for $114.87 +/- 0.14 (P <0.001). Interactions (P <0.001) were detected between frame score and BW groups, and muscle score and BW groups on the selling price of cattle. A number of management and genetic factors affected the selling price of feeder cattle.
