POULTRY FEEDS AND FEEDING 



mineral matter without the addition of any extra bone 

 meal. Ground rock phosphate is usually a cheap source 

 of mineral matter and may be used in place of ground 

 bone. Freshly ground bone, fed at the rate of from one- 

 half to three-fourths of an ounce per hen daily will take 

 the place of meat scrap in the mash for laying hens and is 

 greatly relished by them. Too much of this fresh bone 

 will cause diarrhoea and looseness of the bowels. As a 

 rule the use of this green-cut bone involves too much 

 labor, time and expense to make its use advisable where 

 any considerable number of fowls are kept. 



FISH MEAL 



Fish meal is made from the waste parts of fish products 

 as a by-product from fish canneries and from the manu- 

 facture of glue and similar products. In some cases fresh 

 fish not suitable or adapted for use as a human food is also 

 made into fish scrap. Fish meal and scrap give good re- 

 sults as a poultry feed and may be used to replace all or 

 part of the meat scrap to advantage. From experiments 

 reported by the U. S. Department of Agriculture, fish 

 meal appears to be equal to meat scrap of the same protein 

 content. It is considerably higher in mineral matter than 

 most meat scrap, a fact which helps to make it a good 

 poultry feed and also of special value in the mash for 

 baby and growing chickens. 



Along the seashore, especially in sections where ducks 

 are produced extensively as on Long Island, fish are 

 caught, boiled up, and used extensively in feeding ducks
