Consisting of Timothy Hay 

 or Corn Silage or Corn 

 Stover or any two or 

 three of them, make a

 clover or alfalfa hay. 



When feeding one pound of 

 grain for each four pounds 

 of milk per day 



For cows producing less than 

 15 lbs. of milk per day, make 

 a mixture containing l:ti.5 of 

 net energy. 



If producing over 15 lbs. milk 

 per day, make a mixture 

 containing 1:4 of net energy. 



For cows producing milk test- 

 ing 3 to 3.5% fat. Protein 

 1 to 5 net energy. 



For cows producing milk test- 

 ing 3.5 to 4.5% tat, Protein 

 1 to 5.5 net energy.

 20 lbs. of milk per day, make 

 a mixture containing 1:4.5 of 

 net energy. 



If producing over 20 lbs. milk 

 per day, make a mixture con- 

 taining 1:5 of net energy.
