A spring green-up that was 10 to 14 days ahead of schedule fueled demand that pushed average prices $3 to $12 higher during March. Steer calves weighing 400 to 500 pounds saw average bids of $199.16 per hundredweight, $12.69 higher than February. Yearling steers weighing 600 to 700 pounds increased $4 per hundredweight to average $160.35. Heifer calves sold for an average of $171.05 per hundredweight, a gain of $5.04. Yearling heifers weighing more than 600 pounds saw average bids of $141.63 per hundredweight, an increase of $3.29. Prices for all classes of cattle are up 20 percent over last year.
