I4fi MAKING POULTRY FAY 



Not all the protein and carbohydrates in the 

 feeding stuffs are digestible. A certain per cent is 

 wasted and voided in the process of digestion. For 

 fowls the per cent of waste is not known, nearly all 

 digestion tests having been made with cattle, sheep 

 and horses. It seems very probable that the powerful 

 apparatus of crop and gizzard enables the fowl to ex- 

 tract more of the food value than in the case of ani- 

 mals. 



In computing a ration for laying fowls or for 

 growing chicks the most satisfactory and economical 

 ratio will be about one to six ; that is, the substances 

 fed should average about that ratio, while the potential 

 energy should be about lOO. For fattening a better 

 ratio is one to eight, with a potential energy of io8.
