366 THE ESSENTIALS OF AGRICULTURE 



480. How much grain to feed. The grain ration should be 

 regulated by the amount of milk produced. The rule of feeding 

 i pound of grain for each 3 or 4 pounds of milk produced is 

 fairly safe. A cow giving rich milk should be fed i pound of 

 grain to 3 pounds of milk produced, while a cow giving low- 

 testing milk should have only i pound of grain to 4 pounds 

 of milk. 



The dairy ration should be home grown in so far as possible. 

 The rest of the protein needed for balancing the ration is usu- 

 ally supplied in the mill feeds, such as bran, cottonseed meal, 

 and linseed meal, which must be purchased. 



481. Rations for cows. The following rations contain enough 

 nutrients for a cow weighing 1000 pounds and producing 

 25 pounds of 4-per-cent milk daily. Cowpea hay can be replaced 

 by alfalfa, clover, or soy-bean hay. Corn can be replaced by 

 barley. Linseed meal can be replaced by cottonseed meal 

 or gluten meal. Silage is considered a roughage and, when 

 added to any of the rations, 3 pounds of silage is equivalent to 

 i pound of hay in supplying bulk to the ration.
