Feeding Dairji Cattle 



that this feed supplies this and that feed supplies some other 

 necessary thing, but in the present state of our knowledge 

 we can only urge variety and legume hays. 

 THE COST OP THE RATION 



The other important factor on which the selection of feeds 

 as based is cost. The proper way to select concentrates to 

 supplement roughage is to start with the selection of the 

 five or six feeds that are truly the cheapest on the market 

 and then make up a proper mixture taking into considera- 

 tion all the other factors. 



To make this lesson clear and concrete we will take 

 typical quotations and select the six feeds that are truly the 

 cheapest. Those feeds are truly the cheapest which give us 

 the most digestible material for one dollar. 



The following table has been prepared to show which 

 feeds at typical quotations give us the most digestible 

 material for one dollar. This table has been computed both 

 before the manurial value has been taken out and after on a 

 Tiet basis :

The pounds of total digestible nutrients in one ton in the 

 third column of this table are found by adding the pounds of 

 digestible protein, the pounds of digestible carbohydrates, 

 and the pounds of digestible fat after the fat has been multi- 

 plied by 2.25. This is the digestible material which we pay 

 for. The rest, from the standpoint of the feeder, is waste. 

 Then it is reasonable to select those feeds for the mixture of 

 concentrates which will give the most digestible material for 

 one dollar. To make this selection easy the .fourth column 

 is given. This column gives us the cost of loo pounds of
