The three cows were designated as A, R, and L. T. The two 

 rations compared were as follows : 



Ration 1. 



Timothy hay ad lib. 



Corn meal 2 pounds. 



Cotton-seed meal 2 pounds. 



Gluten meal 2 pounds. 



Ration 2. 



Timothy hay ad lib. 



Corn meal 6 pounds. 



Ration 1 was fed to A during the first and third periods, and to 

 R and L. S. during the second or middle period. Rxtion 2 was 

 fed to A in the middle period and to R and L. S. in the first and 

 third periods. 



A record was made of the food consumed and of the weights of 

 milk produced. During the last five days of each period the milk 

 was analyzed. The butter was also submitted to tests for melting 

 points, the percentages of volatile acids and for the iodine absorp- 

 tion equivalent. 



The data are all given in the subsequent tables.
