The above feedstuflfs are divided into starchy and protein feeds. 

 The former are purchased primarily to increase the digestible matter 

 in the daily ration, while the latter are bought not alone to give more 

 digestible material but to increase the protein in the ration feed to 

 the animal. 



How to use the Key. 



It is not possible in this connection to show the relative effects of 

 the various feed stuffs on the flow of milk or the production of beef. 

 The figures are offered rather as a key to the comparative commercial 

 values of the different feeds based on the nutrients contained in 

 them. Thus if corn meal is worth 100, Quaker oat feed would be 

 worth 85 ; or if wheat bran is worth 85, cottonseed meal would be 

 worth 152. These figures can be easily converted into dollars. 

 Thus if corn meal is worth $16 per ton or 100, Quaker oat feed
