CONFORMITY TO THE GUARANTEES 



The chemical analyses reported in this bulletin were made by the 

 methods approved by the Association of Official Agricultural Chemists. 

 Of the 707 samples analyzed, 667 were ingredients and mixed feeds, and 40 

 were canned cat and/or dog foods. Forty-three brands were sampled 

 at two or more different times during the year. In addition, 6 samples 

 were submitted for analysis in a special study of the bulk sampling prob- 

 lem. These six samples all met the guarantee. 



Table II shows the percentage of samples not conforming to guar- 

 antees over a period of years. A distinct improvement is noted in 1954. 

 Of the analyses reported in this bulletin of the 707 samples submitted, 8.8 

 percent contained less protein, 5.2 percent contained less fat and 3.8 per- 

 cent contained more fiber than was guaranteed. 



It is common practice to indicate by different type those brands fail- 

 ing to conform to the guarantee by an arbitrary amount. In this bulletin 

 the analytical figures, Vi percent or more below guarantee in protein, 14 

 percent or more below in fat, and one percent or more above guarantee in 

 crude fiber, are printed in bold face type. The brands not registered with 

 the Control Supervisor at the time of sampling are indicated by means of 

 an asterisk before the brand name.
