82 THE BEGINNER IN POULTRY 



in fat than the gluten meal given in the table. The 

 glutens are the waste of starch manufactured from corn. 

 Malt sprouts and brewers' grains are a by-product of 

 malting, as their names imply. The source of cottonseed 

 meal is also known from its name, but it is a by-product, 

 the cotton itself being the chief aim. Buckwheat 

 middlings, a good egg feed, is the refuse from manufac- 

 turing buckwheat flour, and there is a buckwheat bran, 

 coarser, containing more fiber, and of less feeding value. 

 Linseed meal is the waste from producing linseed oil. 

 The old process did not extract so much oil as the new 

 process, hence the difference in analysis. A ground 

 linseed is also to be had, but, as it contains over 30 per 

 cent of fat, is not recommended as poultry feed. 



I desire that you will give much thought to the above 

 table, because upon the proper combination of the pro- 

 teids with the other food elements may rest your ultimate 

 success. It is really primer work. Other things count 

 strongly, but this point must be emphasized. 



The fact before mentioned that protein is often more 

 costly in some one of these feeds than in the others has 

 much bearing. This feature is not constant. That is, 

 supply and demand or market manipulations may send 

 the price of the very one you like best up to such an ex- 

 tent that the protein, in which it is rich, may cost you 

 possibly twice as much as the same amount of it in some 

 other item from the table. If you cannot classify the 

 feeds, here is an excellent chance for you to stumble 

 over a pitfall. Suppose that flaxseed is very high in 

 comparative price, this year, while buckwheat is very 

 low. This may mean that the two by-products from 

 these grains will have about the same comparative actual
