Growing stocker cattle on pasture is an intermediate growing phase within the beef production system. Steers or heifers (stockers) grazed on pasture are generally a low cost way of growing light-weight cattle, 300 to 500 pounds, into feeder cattle weighing 750 to 800 pounds. Profitable stocker production requires that the producer understands the factors that impact efficient, low-cost weight gain. The three main factors that determine profitability are: price received when selling the cattle, cost of cattle, and cost of gain. For brevity’s sake we’ll focus on the cost of gain.
