POULTRY MEAT 217 



quantities of hair, horn and hoof, it is not desirable. Particles 

 of horn and hoof resemble bits of brown glass. 



Tankage, dried blood and kindred packing-house by-products, 

 though suitable for hog feeding, are not relished by poultry. 

 They are rich in nitrogen, but not capable of digestion by fowls. 

 Shun them. 



Green cut bone is one of the most palatable foods of animal 

 origin, and also one of the most forcing foods for egg production. 

 It must be fed sweet by all means, which renders it a difficult 

 food to handle on a large scale, especially in the summer time. 

 The practice is to collect the bones, together with meat trimmings, 

 from nearby butcher shops, and grind them at home by means of 

 a power bone cutter. The ground bone and mangled bits of 

 meat which cling to the bone are then fed separately or mixed 

 with a little dry mash. 



Green cut bone heats and spoils very quickly, even in cold 

 weather, unless it is spread out so that the air can circulate freely 

 through it. If fed in a heated condition it is almost certain to 

 develop diarrhea and kindred troubles. It is laxative at best, 

 therefore it is not a good food for young chickens. When given 

 to laying stock to assist egg production, green bone should not 

 comprise more than ten per cent of the ration. Excessive use of 

 such stimulating food is a serious tax on the liver, and brings 

 about symptoms similar to gout in man. Very few egg farms of 

 any size have the facilities to feed green bone, consequently they 

 depend upon the commercial forms of meat scrap, which can be 

 kept indefinitely in any climate, providing they are stored in a 

 dry place, and are not allowed to heat. 



Granulated bone, or bone meal, which is a finer grinding of 

 the bones, are both excellent foods for poultry, and especially 

 for young stock, since they are valuable sources of both protein 

 and mineral substances. This product is free from meat. The 

 raw bones are dried, then ground to a meal. The best way to 

 feed it is in the mash. It has no laxative properties to speak of, 

 and fowls relish it. From five to ten per cent of bone meal 

 should enter all mashes for chicks of all ages.
