Water Soluble Protein in Meat Scraps and Fish Meal. 



Experimental work at the Indiana Experiment Station^ has indicated that 

 the water insoluble protein of meat scraps is a more accurate index of their food 

 value than the total protein, although rations containing scrap of high water 

 soluble protein content can be so balanced by the addition of the proper supple- 

 mentary feeds as to compensate for certain deficiencies. 



As a result of this work in Indiana, all samples of meat scraps officially col- 

 lected in Massachusetts during the season of 1932-33 were analyzed for water 

 soluble protein. The amount of water soluble protein in meat scraps is dependent 

 upon the character of the material rendered. Material high in connective tissue 

 is also high in water soluble protein. Factory inspection has not been at- 

 tempted; consequently we have no record of the kind of material used, and the 

 results are appended simply to indicate the nature of the meat scraps sold in 

 Massachusetts in relation to their water soluble and water insoluble protein.
