Oai feed is a by-product from the milling of oats, and contains oat hulls and 

 oat middlings. It is a component of most horse and stock feeds, and until 

 recently very little has found its way into the markets unmixed. Of late, 

 owing to an increase in output and to the scarcity of other feeding stuffs, an 

 increased amount has been sold. It is somewhat less digestible than barley 

 feed, and is usually offered at retail at a price out of proportion to its feeding 

 value or wholesale price. If sold at a reasonable price, it can be used as a 

 roughage, or not to exceed 30 per cent, as a component of a grain ration. 



Diamond Dairy Feed consisted largely of ground grain screenings. 



Holstein Feed and Bine Grass Valley Feed were mixtures of wheat products 

 and cob meal. 



Poultry Mashes and Meals were of the usual quality. Those containing 

 over 10 per cent, of ash usually had some inorganic substance, such as phos- 

 phate of lime or calcium carbonate, which, while probably necessary to the 

 fowl, could be purchased where needed much cheaper than as a part of the 

 mash mixture. 



Animal Products. Meat and Meat and Bone. — These products are classi- 

 fied in accordance with the following definitions as adopted by the Association 

 of Feed Control Officials : — 



"Meat Scrap and Meat Meal are the ground residues from animal tissues, 

 exclusive of hoof and horn. If they contain more than 10 per cent, of phos- 

 phoric acid they must be designated Meat and Bone Scrap, and Meat and 

 Bone Meal. If they bear a name descriptive of their kind, composition or 

 origin, they must correspond thereto. 



"Digester Tankage is the residue from animal tissue, exclusive of hoof 

 and horn, specially prepared for feeding purposes by tanking under live 

 steam, drying under high heat, and suitable grinding. If it contains more than 

 10 per cent, of phosphoric acid it must be designated Digester Meat and 

 Bone Tankage." 



The Poultry Scraps put out by the Greene Chicken Feed Company, being 

 a mixture of fish, meat, bone and lime, were decidedly inferior, as were the 

 Old Fashioned Meat Scraps sold by the same company. Prosecutions on 

 account of improper guarantee were entered for the sale of these goods and 

 the manufacturer found guilty. 



Fish scraps or meal, of which three varieties were found, form satisfactory 

 feeds for poultry, provided they can be purchased at a reasonable figure.
