find that in feeding a liberal allowance of roughness the grain can be reduced. Hence, the importance of providing roughness rich in protein, like alfalfa.” SELLING FARM PRODUCTS THROUGH THE COW No other branch of agriculture presents more advantages than dairying--disposing of the products of the farm as milk and butterfat. When the latter may be sold to creamery stations and the skim milk fed to calves and pigs along with alfalfa the profits are greater than from almost any other form of agriculture. No other business tends so rapidly to build up the fertility of the farm, and, when judiciously conducted, no other branch of farming yields more satisfactory financial returns. Raising and feeding alfalfa will add from 15 to 30 per cent to the profits of dairying over the use of any other feedstuff that may be raised or bought. The profit problem for the dairyman is constantly to find the feed that will decrease the cost of his production. The diagram below, prepared by the editor of the _Nebraska Farmer_, is to “represent the digestible protein or milk property contained in different kinds of roughness. Points represent the decimals of a pound, and the bars are an exact representation of the superiority of one kind of food over another for the production of milk. Each bar represents 10 pounds of roughness. The approximate yield is also given per acre:” Approximate Yield Per Acre.
