March, 1915] analysis of feeding-stuffs. 9 



crude fibre and nitrogen-free extract. A feeding-stuff 

 which contains small amounts of moisture, ash and crude 

 fibre must be classed as high grade, if digestible. When 

 these constituents are present in small amounts the total 

 amount of the valuable constituents — protein, fat and 

 nitrogen-free extract — must be high. 



THE VALUE OF A CHEMICAL EXAMINATION OF 

 COMMERCIAL FEEDING-STUFFS. 



The chemical analysis of feeding-stuffs is valuable in 

 many ways, chief of which are the following : 



1. It shows whether or not the guarantees of the manu- 

 facturer are correct. 



2. It protects the buyer against the unscrupulous manu- 

 facturer or retailer. 



3. It aids the buyer in deciding mone}^ values in pur- 

 chasing feed. 



4. It affords a clue as to the nature of the constituents 

 of the feed. 



5. It furnishes data for making up any desired feeding 

 ration. 



6. It enables the consumer to decide whether it is a 

 useful feed for his particular purpose. 



7. It protects the manufacturer of good products. 



The following definitions are given for the use of the 

 consumer and represent the terms used for the particular 

 feeding-stuffs bj^ the general trade :

 lint, and bj' analysis must contain fortj'-nine per cent of
