Quantities of grains and roughages to feed. The grain ra- 

 tion should be fed in proportion to the quantity of fat or milk 

 produced by the cow. A good rule to follow is to feed one 

 pound of grain a day for every pound of butter-fat produced 

 during the week. Another method is to feed one pound of 

 grain to each three pints, or three pounds, of milk produced 

 daily by the cow, except in case of a cow producing forty 

 pounds or more of milk, when one pound to each three and one- 

 half or four pounds, or pints, of milk is fed. Usually a cow 

 should be fed all the roughage she will eat up clean. If, how- 

 ever, she starts to become fat, the quantity should be lessened. 



These rules serve only as guides and should be modified ac- 

 cording to the capacities of the animals to convert the feed into 

 milk.

 much water. About 87 per cent of cow's milk is water. 

 The water should be pure ; stale water is distasteful to the 

 animal and she will not drink enough for a maximum milk 

 production. When cows are stabled and do not have access to 

 running water, they should be watered two or three times a day. 



More than most animals, the dairy cow requires abundant
