FEED STUFFS SUITABLE FOR POULTRY. 



The body and feathers of a fowl consist of water, ash, pro- 

 tein and fat; so it is clear that the feed supplied must con- 

 tain the compounds that will supply these. About one-half 

 of the dry matter in the body of a fowl is protein and about 

 8 per cent, is ash. Investigations made by Jenter at the New 

 York Experiment Station show that the body of a Leghorn 

 hen body, blood, bones, feathers and viscera contains 55.8 

 per cent, water, 21. G per cent, protein, 3.8 per cent, ash, and 

 17 per cent. fat. 



A fresh egg is made up of, shell, 11.4 per cent.; water, G5.7 

 per cent.; fat, 8.9 per cent.; protein, between 11 and 13 per 

 cent. Of the total dry matter in an egg, including the shell, 

 there is 35.G per cent, ash, 25.9 per cent, fat, and 33 to 38 per 

 cent, protein. 



Carbohydrates and Fats. These supply the fat forming and 

 heat producing compounds. The fats are capable of doing 

 about 2.4 times as much work as the carbohydrates. These 

 are contained in the common grains used as feed stuffs. 



Ash. This is the material from which bone and shell are 

 built up. 



Lime is the compound which enters so largely into the com- 

 position of the egg shell, and must be supplied in some other 

 way than in the ordinary feeds grain and grass. 



Animal Feeds. These consist of highly nitrogenous feed 

 stuffs made from meat scraps, blood, dried fish and skim milk. 



Waste meat, such as beef heads, scrap and other waste 

 products may be fed either cooked or raw. If cooked, the 

 juices in which the meat is cooked should be mixed in with 

 the mash. 



Dried blood is a concentrated food containing a large per- 

 centage of protein. It can be fed in mashes to growing chicks 

 or laying hens. It should be mixed 1 part to 16 of meal. 



Ground Raw Bones. If raw bones are ground up fine so 

 fowls can eat them they are much relished.
