COMMERCIAL FEEDS 



J. M. PicKEL, Feed Chemist.* 



The analyses of concentrated commercial Feeding Stuffs published in 

 this Bulletin comprise all those made during the year ending midsum- 

 mer, 1914. The total number of samples analyzed is 375, of which 287 

 samples are official, that is, were drawn by our official inspector; the 

 remainder, 88, are unofficial, that is, were sent in by citizens of the State. 



There were in all 954 guarantees; in 270 cases (28 per cent) the feeds 

 were below guarantee; the remainder (72 per cent) up to, or above 

 guarantee. The discrepancy below or above guarantee was usually 

 insignificant. If only cases in which protein and fat were respectively 

 1 or more per cent and 0.5 or more per cent below guaranteed, and fiber 

 1 or more per cent above, or taken into account, then of the total 954 

 guarantees only 11 per cent were not as good as guaranteed. 



The following table gives a general summary of the different classes 

 of feeds analyzed, the number of each, the number of guarantees on 

 protein, fat and fiber; the number of cases, and their percentage, that 

 fell below guarantee : 



•Assisted by J. Q. Jackson, E. S. Dewar, W. H. Stroud. Only a small fraction of the time — as 

 much as is implied by the making of the protein determinations — ^of these gentlemen was given to 

 the work of this bulletin. In addition to the duties of feed chemist, Dr. Pickel has charge of the 

 toxicological and water work of the Department.
