To insure the proper amount of protein in the ration, 

 about one-half of the feed should 1)e chosen from among 

 those containing a high amount of protein. The following 

 mixture is suggested, taking all of these things into account : 



500 lbs. hominy $7.50 



500 lbs. distillers' dried grains 8.19 



500 lbs. mixed feed 6.69 



300 lbs. gluten feed 5.03 



200 lbs. oil meal 3.70 



2000 lbs. (one ton) $31.11 



It is seen that looo pounds of this mixture is made up of 

 distillers' grains, gluten feed and oil meal. The oil meal 

 was not chosen as yielding total nutrients very cheaply, but 

 because the writer wishes particularly to have a little oil 

 meal in his ration. All the others in the suggested mixtures 

 will be found to yield total digestible nutrients the cheapest. 

 The author has found this method of great assistance in 

 studying the relative value of feeds and in forming a basis 

 for the choice of feeds. In using this method current prices 

 of feeds should be substituted for those given and the table 

 calculated over. Your farm bureau agent usually has the 

 prices. 



The above mixture is advised with practically any rough- 

 age. It would go particularly well with clover hay and corn 

 silage. If no silage is available it will be noticed in the table 

 that dried beet pulp and malt sprouts are relatively cheap 

 feeds. They make excellent succulent feeds if soaked eight 

 or ten hours before feeding. Not as much other grain would 

 be needed with these soaked grains.
