sale in this state must have affixed in a conspicuous place the fol- 

 lowing statement : * 



Name of feed stuff, 

 Name of manufacturer. 

 Address of manufacturer, 

 Net weight of package, 

 Guaranteed percentage of protein. 

 Guaranteed percentage of fat. 



In case of adulteration the true composition of the mixture must 

 be plainly marked upon the package. In case foreign material is 

 added to standard grains or by-products, the mixture must bear a 

 distinctive name or brand, and the true character of the admixture 

 must be stated upon the label. 



As a guarantee of protein and fat are required by 

 How a feed law these determinations are, with but few excep- 

 stuff is tions, made upon all feed stuffs collected. The 



examined. protein guarantee is required because protein is the 

 most valuable component and the one most neces- 

 sary to supplement the home grown coarse fodders and cereals. 

 The fat guarantee is required since it serves to a certain extent as 

 an index of the quality of a feed. A fiber determination is often of 

 great value in detecting adulteration with oat hulls, ground corn cobs 

 and other low grade material. A fiber guarantee would be desir- 

 able and is required in many states. 



The microscope is used to detect adulteration and also to deter- 

 mine the ingredients used in making up a compounded feed. 

 Microscopic observations are also valuable in corroborating the 

 evidence obtained by chemical analysis. Ash determinations are 

 made on poultry feeds, first because a high ash content in a mash or 

 scratch grain indicates an excessive amount of added grit, and sec- 

 ond, because in case of beef scraps and meat and bone meals the 

 ash content is indicative of the amount of bone incorporated, or 

 contained in the product. 



*Hays and straws, the wliole seeds or the unmixed meals made directly from the entire 

 grains of wheat, rye, barley, oats, Indian corn, buckwheat and broom corn, wheat bran, 

 wheat middlings, wheat mixed feed, and the pure grains ground together and unmixed with 

 other substances are exempt from the provisions of this Act.
