DAIRY CATTLE AND MILK PRODUCTION 



This leaves 1.26 pounds of digestible protein and 6.59 

 therms of energy to be supplied by the grain. Since corn is 

 grown on the farm, we will use it as far as possible in making 

 up the grain ration. The amounts to be used can only be 

 found by trial. We will start with the following : Corn 6 

 pounds, bran 3 pounds, cottonseed meal 1 pound. This 

 would give us the following amount of protein and energy 

 values : 



This gives too much energy value and is a little low in the 

 protein. Since cottonseed meal is the highest in protein, we 

 will cut out the bran and increase the cottonseed meal by the 

 addition of another pound. We would then have the fol- 

 lowing :
