 Animal Products (Meat and Meat and Bone) 



Meat Scraps and Meat and Bone Meals have been classified in 

 accordance with the following definitions, as advocated by the 

 Association of Feed Control Officials. It is hoped that manu- 

 facturers will in the future be guided by these definitions in naming 

 their products. 



" 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 phosphoric 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 tank- 

 ing 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." 



If this definition is followed a large number of the samples col- 

 lected cannot be considered as meat products, although many 

 were sold as such. 



Fish Meal. The Red Star Brand, manufactured by the Inter- 

 national Glue Co., and the Chic-Chuk, manufactured by the 

 Russia Cement Co., are residues after the extraction of glue from 

 fish. Chic-Chuk is derived from fish skins and back bones, together 

 with such flesh as is not removed in making boneless fish products 

 from salted and cured cod and hake. This material is first thor- 

 oughly washed to remove the greater part of the salt, the glue is 

 then extracted by cooking and pressing, and the residue dried and 

 ground to be used either as Chic-Chuk or fertilizer, depending 

 upon the quality of the original stock, the better grades being used 

 for poultry food. It must of necessity contain a high percentage 

 of bone. The manufacturers claim that it does not taint eggs and 

 poultry, as does meal made from the waste of mackerel and herring 

 and other oil-bearing fish.
