If all feeder cattle were identical and if all relative prices were constant the feedlot manager would still have an important and difficult decision to make. The decision involves selecting the time at which to replace a pen of cattle on feed with a new pen of feeder cattle such that profit is maximized, over time, to the feeding operation as a whole. Of course, all cattle are far from identical and prices, even relative prices, are never constant. The decision that is not simple with identical cattle and constant prices becomes most difficult with consideration of different types of replacement cattle and varying prices.
