CHAPTER XII 

 CONCENTRATED FEEDS 



A concentrated feed, as one would naturally suppose, is 

 just the opposite of a roughage. The two most common 

 forms are seen in the grains of cereals and some other agri- 

 cultural plants, and in the by-products of mills, where the 

 cereals are converted mto flour, breakfast foods, starch, etc. 

 There are some other concentrates, that are products of such 

 large manufacturing industries as the Unseed and cotton- 

 seed oil mills, and the packing houses. In addition are also 

 what are commonly known as "commercial feeds," these being 

 combinations of various grains and concentrate by-products, 

 and are sold under trade names on the market. These are 

 all called concentrates, because, as a rule, they lack in coarse, 

 fibrous structure, and contain larger percentages of protein 

 and starchy matter than forage plants. For example, the 

 grain of corn is a concentrate, one hundred pounds of which 

 contains fully three times as much digestible protein and 

 twice as much digestible carbohydrates as are found in corn 

 fodder. Using another illustration, gluten feed, which is 

 made as a by-product in the manufacturing of starch from 

 corn, contains three times as much protein as the same 

 weight of corn. 



The cost of concentrated feeds is always much greater 

 than that of roughages. In fact, the cost of most feeds sold 

 on the market increases as the amount of protein in them 

 increases. Feeds like cottonseed meal and tankage, con- 

 taining large amounts of this nutrient, are usually high- 

 priced, although that fact does not mean that they are 

 expensive feeds to use. Sometimes the price of a certain con- 

 centrate is low on account of a glutted market or high because
