WHAT CROPS FOR FEEDING 51 



Thus one side of the feeding problem is settled. 

 The other side, the protein side, remains unsettled, 

 and is the real necessity for the purchase of grains 

 and store feeds. And right here is where most 

 men pay too much for their whistles. They get 

 the wrong feed ; they select one without due regard 

 as to what it contains. Now, mind you, it is pro- 

 tein that you want. Why will you buy a food, a 

 grain food though it be, and rich in starch, when 

 your silo, your haymows, and your corn shocks are 

 just fairly bulging out with this constituent already? 

 When you do this, you simply haul home what you 

 have already in abundance; you are buying a 

 whistle for which you have no need. 



But your real problem is to get protein, to select 

 a feed that analyzes high in digestible protein es- 

 pecially, and relatively low in all other constituents ; 

 and you can do this most wisely only by comparing 

 the several feeds on the market and judging them in 

 reference to the protein content and the cost of each 

 protein unit in the feed. 



Corn and Cottonseed Meal. Let me use corn 

 as an example. You know how excellent corn 

 is as a hog food, a horse food, a food for fat- 

 tening cattle; it is superior for these purposes, 

 because it is rich in starch and fat, and in being so 

 makes heat, fat and energy cheaply and abundantly. 

 As a milk producer, however, it is inferior, because 

 it is deficient in protein, the very constituent so 

 needed in dairy rations. Why buy it for dairy 

 cows, therefore, if it does not possess the one con- 

 stituent you need and are seeking? Is it not better 

 to choose another feed, some kind that carries pro- 

 tein abundantly? I think so. Indeed, we have 

 many foods far superior for milk cows than corn. We
