He then has no recourse under the feedingstuffs law if the feed which 

 he purchases is of inferior quality. The dealer who offers for sale a 

 feedingstuff which has not been registered and which is not guaranteed 

 in compliance with the law is probably indifferent to his customer's 

 interests in other respects. He does not merit either the confidence 

 or the patronage of the consumer. The purchaser's cooperation in re- 

 fusing to buy a feed which does not conform to the law in every respect 

 will not only help in the enforcement of the law but will at the same 

 time afford the purchaser himself the protection of the law. If the 

 buyer fails to assure himself that the legal requirements have been met, 

 he accepts the feedingstuff at his own risk. The terms used in reporting 

 the chemical analysis of a feedingstuff are briefly defined as follows: 



Protein is a collective term for a considerable group of compounds, 

 all of which contain nitrogen. Ingredients high in protein are usually 

 more expensive than the other ingredients, making protein the most 

 important nutrient for consideration in determining the commercial 

 value of a feedingstuff. The nutritional value of the proteins varies 

 widely; therefore a feedingstuff should contain protein from several 

 sources to insure inclusion of all essential types. 



Fat is separated from the other components of a feedingstuff by 

 extracting the moisture-free sample with anhydrous ether. In such 

 ingredients as the cereals, the seed-meals and animal products, the ex- 

 tract is nearly pure fat. A few ingredients such as alfalfa meal contain 

 some ether-soluble material which is not fat. 



Fiber is composed of cellulose and related compoimds. Since crude 

 fibre has little feeding value, the law requires that the maximum fiber 

 be guaranteed rather than the minimum as in protein and fat.
