ALFALFA AND THE DAIRY 147 



at five dollars per ton. Knowing the cost of these differ- 

 ent rough feeds and having this table before him, a feeder 

 can tell which is the most economical feed to use. It will 

 be noticed that the table is divided into two parts, the 

 first part giving the value of the total nutrients, and the 

 second one the value of the protein nutrients. It fre- 

 quently happens that we have plenty of carbohydrates 

 and fat, but that we are lacking in protein. In this case 

 we would consult the 'protein nutrients' column in order 

 to determine what feed to buy in order to furnish the 

 protein most economically. If it be carbohydrates and 

 fat as well as protein that is required, as was the condi- 

 tion in the dry year of 1901, then we should take the 

 total nutrients' column. When it is possible to get a 

 rough feed containing a large amount of protein, we 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 advan- 

 tages 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
