DAIRY CATTLE AND MILK PRODUCTION 



77.3 pounds of water, while the one producing one half that 

 amount of milk consumed 40.3 pounds of water. The con- 

 sumption of water was in practically the same ratio as the 

 production of milk. The ration consisted of grain, alfalfa 

 hay, and corn silage, fed in the ratio of 1 : 1 : 4, and was identi- 

 cal for the two animals, except it varied in quantity to meet 

 their individual needs. The temperature of the barn and of 

 the water used varied from 45 to 55 F. 



The table below shows the enormous quantity of water 

 consumed by a cow producing over 100 pounds of milk per 

 day. This animal was fed a ration of alfalfa hay and grain 

 with a small feed of silage. The water was given three times 

 daily at a temperature of about 80 F. 



WATER CONSUMED BY MISSOURI CHIEF JOSEPHINE 



This cow produced approximately 4 pounds of milk to 1 by 

 No. 27 as given in the preceding table, and the consumption of 

 water was in about the same ratio. When cow No. 27 was 

 producing milk, the consumption of water was 77.3 pounds per 

 day, while on maintenance she consumed only 14.7 pounds.
