DESCRIPTION OF FEED STUFFS 



normal temperature is low enough to keep the flesh in 

 good condition. The sterilization used in making dried 

 meat scraps kills all the disease germs which may be in 

 the fresh flesh. During cool and cold weather, fresh meat 

 products, such as injured horses and other animals not 

 commonly used for human food, are fed to poultry either 

 ground up or in whole chunks. 



Fresh green bone and some scraps are secured from 

 various markets and local butchers, and fed to poultry 

 after being run through a bone grinder. Small bone 

 grinders operated by hand power are used where only a 

 few hens are to be fed, but a power grinder is essential 

 where this product is to be ground up for any consider- 

 able number of fowls. No satisfactory method has been 

 found to preserve fresh meat to feed to poultry, other than 

 the commercial process of making meat scrap which in- 

 volves extensive and expensive machinery, making it im- 

 practical to preserve any quantity of meat in a small way 

 for this purpose. 



Bone meal and ground or crushed bone are fed to a 

 small extent to poultry either by adding from 2 to 5 per 

 cent of these products to the mash or by keeping one of 

 them before the growing chickens. These mineral prod- 

 ucts are sometimes fed to laying hens, but their use is not 

 general. Where the rations are deficient in lime (cal- 

 cium) and phosphorus the necessary mineral matter can 

 be most easily and cheaply supplied by these bone feeds. 

 The meat scraps used in feeding poultry usually contain 

 considerable bone, thus furnishing a sufficient amount of
