262 ELEMENTARY TREATISE ON STOCK FEEDS AND FEEDING 



9. "The ration must consist of foods which furnish the nu- 

 trients at the lowest possible cost. 



ID. "The food in the ration must not have an injurious effect 

 on the color or the flavor of the product. 



II. "It is not how much a fowl eats, but how much it can 

 digest, that determines the value of the food. Various classes 

 of animals differ in their power to digest the same kind of 

 food. Foods also vary in their digestibility when used by the 

 same animal. Unfortunately the proportion of each poultry 

 food which fowls can ordinarily digest, has not yet been deter- 

 mined, therefore we are obliged to use the standards of digesti- 

 bility which are used in compounding rations for other animals."

Use of the Table. — Rations for fowls may be figured in a simi- , 

 lar way as for farm animals by the use of Table i and this table 

 of poultry standards. In making up rations for fowls, large 

 amounts of feed may be mixed at one time, as it would not be
