POINTS OF INTEREST TO PURCHASERS. 



Consult the annual bulletin and find out what companies are most con- 

 sistently meeting their guarantees. 



Do not buy a feed simply because it is cheap without comparing the 

 guaranteed analysis with that of other feeds that may be available and 

 also examine it carefully to determine, if possible, the ingredients of 

 which it is composed. In these times of high prices, one should consider 

 these points carefully. 



Do not send samples for analysis without first writing for instructions 

 on how to secure a representative sample. A sample from one bag or a 

 small handful taken from the top of several bags is not representative 

 and an analysis of such a sample would be of no value. The cost of mak- 

 ing an analysis is considerable and we cannot take the time to analyze 

 samples that are not representative of the lot from which they were 

 taken. Our inspectors are continually collecting samples of feeding 

 stuffs and in many cases we can furnish information concerning a 

 particular brand of feed without making another analysis. 



When i)urchasing feed in car lots, an inspector will be sent to draw 

 samples if the office of the chemist in charge is notified upon arrival of 

 the car. 



Do not accept feed in untagged or unlabeled bags except such feeds 

 as are exempt from license as heretofore mentioned. An untagged pack- 

 age gives the purchaser no guarantee as to analysis or ingredients and 

 furthermore the product is sold in violation of the feeding stuffs law. 

 Such cases should be brought to the attention of the office of the chemist. 



When buying bulk feeds that are subject to license, demand of the 

 seller a printed guarantee giving the chemical analysis and ingredients — • 

 the law provides that the purchaser may have this information. 



CO-OPERATION WITH U. S. DEPARTMENT OP AGRICULTURE. 



Through a plan of cooperation devised by the U. S. Department of 

 Agriculture the State inspectors are empowered to collect samples from 

 interstate shipment of feed stuffs found in Michigan under the Food 

 & Drugs Act. In this cooperative work fifteen cases were referred 

 to the laboratory of the central inspection district in Chicago; eleven 

 of the samples were collected on account of deficiencies in ]»rotein, and 

 four were taken at the suggestion of the Chief Inspector of the central 

 inspection district.
