FISH WASTES FOR FEEDING ANIMALS 

 J. M. Bartlett 



The increasing demand for animal foods together with the 

 high price and scarcity of beef scraps (which has been the chief 

 supply in the past) has forced dealers and consumers of these 

 materials to look to other sources for a supply. Fish waste or 

 fish of any kind has been known always to be highly relished by 

 meat eating animals and to produce excellent results in growth 

 or egg production. The great objection to its use in large quan- 

 tities has been the tendency to give the flesh or eggs a fishy flavor 

 which is known to be very pronounced in water fowl that live 

 largely on fish. Late investigations have shown that the fishy 

 flavor is due largely to fish oil and when that is quite completely 

 removed as it is now in some fish meals that have appeared on 

 the market the material can be used in much larger quantities 

 without imparting a disagreeable flavor to the product. In Eu- 

 rope waste fish products have been used for feeding animals 

 for several years. Spier of Scotland reports no bad influence 

 on milk when reasonable quantities of dried fish are fed to dairy 

 cows, and in Germany, the better grades of dried fish waste have 

 been used for feeding hogs, cattle and poultry for many years. 

 Experiments conducted at the Experiment Station in Harlis- 

 hausen, indicate that fish meal forms a desirable supplementary 

 feeding stuff for farm animals especially for pigs. It was found 

 that if fed in too large quantities or contained too high per- 

 centages of oil it would produce a fishy taste to the meat prod- 

 uct, but meal containing only 2 percent to 4 percent of oil could 

 l)e safely fed. The phosphate of lime found in the meal is 

 deemed a valuable ajunct in feeding animals. The fish waste 

 should not contain more than 3 percent of salt. It is recom- 

 mended to feed as high as 2 pounds to 1000 lb. cows and one 

 fourth to one half pound to pigs, depending on their size. 



Large quantities of fish wastes are produced along the 

 Maine Coast every year and these, in the main, have been sold 

 to fertilizer companies in the raw condition. Much of this
