CALCULATION OF COMPONENTS OF FEED 

 RATIONS. 



Let us suppose that we have at our disposal the following 

 common feeding stuffs : Fodder corn, clover hay, and wheat 

 bran, and that we want to know how much is required to keep a 

 milch cow of 1000 lbs. live weight in good condition and to 

 secure a maximum yield of milk. We will feed 14 lbs. of 

 fodder corn, 6 lbs. of clover hay, and 10 lbs. of wheat bran. 

 According to the table these quantities contain the following 

 number of pounds of digestible matter : 



This ration falls somewhat short of the feeding standard in 

 total organic matter and digestible substances. To bring it 

 nearer to the standard, we add a couple of pounds of some con- 

 centrated feed. In selecting the foods and deciding the quan- 

 tities to be given in each case, the market prices of the feeds 

 must be considered. We will suppose that a lot of corn-meal is 

 available in this case, and will add two pounds of this feed to 

 the above ration.
