CONFORMITY TO THE GUARANTEES 



The chemical analyses were made by the methods of the Association of 

 Official Agricultural Chemists. Of the 704 samples analyzed, 656 were mixed 

 feeds and ingredients, 23 were canned cat and/or dog foods, 22 were drawn in 

 a study of the sampling of "bulk delivery" of feeds and three were special pro- 

 blem samples. Forty-six brands were sampled at two or more different times 

 during the year. 



Of the samples reported in the 1953 inspection, the analyses of which are 

 published in this bulletin, 17.0 per cent contained less than the guaranteed 

 amount of protein, 10.2 per cent contained less than the guaranteed amount of 

 fat and 4.4 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 II. 



All states have feedingstuffs laws and publish a report. It is common 

 practice to indicate by different type those brands failing by an arbitrary toler- 

 ance to conform to the guarantee. There is no common agreement what this 

 tolerance should be. In this bulletin the analytical figures Vi per cent or more 

 below guarantee in protein, Va 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.
