This criteria removes stock that probably won't cover their costs and does so while the stock still have a decent salvage value. Culling cows and keeping heifers can also provide some different dimensions to your overall management strategy. In addition, heifers can mean an improved genetic base. A base that will position your operation to perform better as the markets turn around. Bred heifers will be in demand when cattle prices improve.
Cattle use farm resources.
Changing the way these resources are used on the farm or the product that these resources produce may bring additional revenue to the farming operation. If you sold a part of your cow herd, resources would be released for other potential uses. For example, suppose a producer sells half of his cow herd, then utilizes his grass and other resources to runs stocker calves. Stocker programs are likely to be more profitable than running cows during the next several years. But, don't just think calves as stockers.
