CONFORMITY TO THE GUARANTEES 



The chemical analyses reported in this bulletin were made by methods 

 approved by the Association of Official Agricultural Chemists. 



Of the 710 samples analyzed, 61 were dry or canned cat and/or dog 

 foods and 649 were ingredients and mixed feeds. Fifty-one brands were 

 sampled two or more times during the year. Table T shows the per- 

 centage of samples analyzed in the thirty-year period 1926-1955 not con- 

 forming to guarantees. It is noted that the percentage is a little higher in 

 1955 than in the year previous. This is due to the selection of brands for 

 sampling which was made with the intention of trying to clear up cases of 

 previous deficiencies. 



The percentage of samples not conforming to the guarantee is 10.3 

 per cent below guarantee in protein, 6.9 per cent below guarantee in fat, 

 and 5.9 per cent exceeded the guarantee in crude fiber. 



Table II lists the analyses of the brands of ingredients and mixed 

 feeds other than the cat and dog foods which are listed in Table III. 



A total of 94 samples represented brands that were not registei'ed with 

 the State Department of Agriculture at the time of sampling. This fact is 

 indicated in the table. 



Eighteen lots of feeds delivered in bulk were officially sampled. These 

 are identified in the table.
