DESCRIPTION OF FEED STUFFS 



and to some extent to poultry. Fresh fish cooked in this 

 manner are greatly relished by all kinds of poultry and 

 make a splendid feed. Ducks grown as green ducks and 

 marketed when from 8 to 12 weeks of age require a con- 

 siderable amount of animal protein such as is furnished 

 by fish products or meat products, but in feeding fresh 

 fish it is advisable to eliminate the fish from the ration two 

 weeks before the birds are to be marketed to avoid any 

 possible taste in the flesh due to the use of this fresh fish. 



A considerable number of the dried fish products are 

 now on the market for poultry feeding and come from 

 many sources. The fish scrap made from whole fish is 

 usually a much better feed than the fish meals which are 

 residue products. The high prices of meat scrap during 

 the war period greatly stimulated the trade in fish meal 

 and fish scrap. These products, like meat scrap and other 

 high animal protein products, should be bought on their 

 protein analysis and their value based on the analysis as 

 compared to similar grades of meat scrap. Some grades 

 of fish scrap cost just as much as the same grades of 

 meat scrap, in which case the meat scrap is usually 

 selected. In some sections and under certain conditions a 

 good quality of fish scrap can be purchased much cheaper 

 than meat scrap, making it a very good feed. 



The oil content of the fish meals varies greatly but a 

 moderate variation in the oil content does not appear to 

 be in any way injurious to the fowls, although fish meal 

 containing a high fat content is apt to spoil more quickly. 

 Fish meal with a quite high oil content has been fed in
