Fish scrap corresponds to meat scrap in many respects, and 

 in some localities it is extensively used. The great difficulty 

 with it is that it is likely to impart a fishy flavor to the eggs and 

 flesh. This is due to the oil. In the best grades, wherein this 

 oil is practically all removed, fish scrap makes a valuable substi- 

 tute for meat scrap, and in most cases it it much cheaper than the 

 latter.

Milk albumen, a by-product from the manufacture of milk 

 sugar, is a good source of animal protein, but in the main it is 

 too expensive for general use as a poultry food. Some breeders 

 use it for their chicks. It is largely casein and lime, ground to a 

 meal, and contains no crude fiber. 



Granulated milk is another product of this kind, except that 

 it is whole milk evaporated and crystallized. Sometimes it is 

 spoken of as powdered milk. It is useful for chick feeding for 

 the first few weeks, but its cost is high, therefore prohibitive for 

 general use.
