COST OF NUTRIENTS IIQ 



a necktie always must b<j purchased with a collar. 

 One may never wear a necktie, or he may have all 

 the ties he needs at home, yet every time he buys a 

 collar he is obliged to pay for a necktie as well. If 

 a necktie is not needed, but only a collar, it is likely 

 the rule would be to get the collar having the least 

 necktie about it and the value of the purchase depend 

 wholly upon the collar and nothing on the necktie. 



If the farmer raises on his farm all he needs of the 

 carbohydrates and fat which have a low commercial 

 value, he cannot afford to buy more of the same con- 

 stituents at a price many times higher than he can 

 raise them himself. Yet the feeder is obliged to do 

 this very thing when he purchases protein. It can- 

 not be helped and it is no one's fault. 



There is a point of practical bearing, however, in 

 this matter. If you have to take carbohydrates and 

 fat along with protein and pay for them, get as lit- 

 tle of the carbohydrates and fat in the feeding stuff 

 as possible and just as much protein as you can. 

 The aim should be to buy the feeding stuff having 

 the highest quantity of digestible protein that costs 

 the least for a pound of protein. 



Expressed in a few words, a good rule to follow 

 is this : Grow all the carbohydrates and fat on the 

 farm; never be placed in a position that requires 

 you to purchase any. Then grow the protein rough- 

 ages, like clover, cowpeas and alfalfa, and little 

 protein will need to be bought. This is economical 

 and practical feeding. It is good farming. 



Purchase of Protein. It is not always practical 

 or possible under ordinary methods of farm practice
