DESCRIPTION OF FEED STUFFS 



mash for poultry contains from 5 to 30 per cent of meat 

 scrap, making 25^ to 15 per cent of the total ration of 

 meat scrap. These meat scraps, however, are also used 

 extensively in commercial mixed mashes. Commercial 

 dried meat scrap prepared in this form will keep in good 

 condition for many months if kept in a moderately cool 

 and dry place. Meat scrap or some product of this nature 

 which furnishes protein of animal origin has been found 

 to be essential in securing the best results both in growing 

 poultry and in the production of eggs. 



Feeding tests with laying hens indicate that a mash con- 

 taining from 18 to 20 per cent of a good grade of meat 

 scrap is most economical. Slightly better production 

 may perhaps be secured by a higher per cent of meat scrap 

 but the extra meat scrap does not produce the efficiency 

 that is secured by smaller percentages. Some of the 

 heavier breeds of fowls, especially Brahmas or Plymouth 

 Rocks, which tend to become too fat, may be kept in good 

 condition by feeding a mash containing a lower percent- 

 age of meat scrap, about 15 to 18 per cent. 



The quality of meat scrap should be carefully deter- 

 mined by its appearance and odor and a more careful test 

 can be made by pouring boiling water on a small amount 

 of meat scrap and noticing the odor of the steaming 

 product which should be like fresh scorched meat. Meat 

 scrap and all of the animal protein feeds should be bought 

 strictly on their protein analysis, the protein content in- 

 dicating the value of the product. Oftentimes the high 

 protein meat feeds are cheaper considering their protein
