 The mixture contains x 100=15.95% protein.

The percentage of fat or fiber may be calculated in a like manner 

 by substituting the fat or fiber figures for those of the protein. 



CONFORMITY TO THE GUARANTEES 



The chemical analyses were made by the methods of the Associa- 

 tion of Official Agricultural Chemists. Of the 547 samples analyzed, 

 11.9 per cent contained less than the guaranteed amount of protein; 

 7.6 per cent contained less than the guaranteed amount of fat, and 

 4.0 per cent contained crude fiber in excess of the guarantee, A com- 

 parison of these figures with those of previous years is shown in 

 Table 1. 



All the states have feedingstuff laws and publish a report. It is 

 common practice to indicate by different type those brands failing by 

 an arbitrary tolerance to conform to the guarantee. There is no com- 

 mon agreement what this tolerance should be. In this bulletin the 

 analytical figures Y^ per cent or more below guarantee in protein, I/4, 

 per cent or more below guarantee in fat, and one per cent or more 

 above guarantee in crude fiber are printed in bold-face type and 

 underlined.
