NUMBER OF SAMPLES FAILING TO COMPLY WITH 



THE LAW. 



Of the 360 brands analyzed only 135 complied with the law 

 in every respect. The 225 which did not fully comply with the 

 law violated it on 295 counts. Eighty-nine brands or 24.7 per 

 cent were deficient in protein, 59 of these or 16.4 per cent were 

 deficient one-half per cent or more. Seventy brands or 19.4 per 

 cent were deficient in fat, 49 of these or 13.6 per cent were de- 

 ficient one-fourth per cent or more. Twenty-one brands con- 

 tained an excessive amount of crude fiber. Sixth-three brands 

 were deficient in carbohydrates. Fifty-two brands were offered 

 for sale without the carbohydrate guarantee. On four brands the 

 sliding scale guarantee was used. The use of the double guar- 

 antee does not meet the requirements of the law and in the fol- 

 lowing pages only the maximum guarantee is published. In the 

 tabulation of the analytical data deficiencies of one-half per cent 

 or more of protein and of one-fourth per cent or moreof fat are 

 shown in italics : 



G. P. Percival and A. W. Petre assisted in making the protein 

 determinations. F. S. Schlenker and W. A. Westgate ass-isted 

 in making the ash determinations. 



REQUESTS FOR ANALYSIS OF FEEDING-STUFFS 



BY CONSUMERS 



The Department is frequently asked to make an analysis of 

 feeding-stulTs for individuals. This service is gladly rendered 

 when the circumstances warrant it. Such samples should be 

 drawn from at least five bags, preferably ten, in a manner to in- 

 sure that the small lot sent for analysis is accurately representa- 

 tive of the large lot from which it is taken. A one-pound sample 

 is sufficient for the analysis. It should be sent in a glass jar or 

 tin box to prevent the loss of fine particles and a change in the 

 moisture content. In order that the Department may know 

 whether or not the manufacturer and the dealer are complying 

 with all the requirements of the law, we request the following 

 information be submitted concerning each sample:
