The rations 

 At the beginning of each year, three rations were computed which 

 were followed as closely as possible in the feeding operations. The amount 

 of product and size of the individual animal were taken into account, 

 so that some cows were fed more than others; but, in general, the rations 

 were followed rather closely. In all the tables, the amounts of feed 

 recorded for each cow were the amounts actually eaten by that animal. 

 Ration I, first year 



10 pounds hay 1 Fed check Group A and alternated with rations 

 35 " silage V II and III with Groups B, C, and D. 



8 " grain j 

 The grain mixture for ration I was mixed, 200 pounds at a time, in the 

 following proportions: 



ist grain T 100 pounds Ajax flakes, 



mixture, 1907-8 < 60 " corn-meal, 



( 40 " cottonseed-meal. 

 After this mixture had been fed for about four weeks, it was considered 

 to be too heavy and the amounts were changed to 



!ioo pounds Ajax flakes, 

 30 " corn-meal, 



30 " wheat-bran, 



40 " cottonseed-meal. 

 One of the check cows, Glista Iota, when put on official test in 1907-8, 

 was fed the following mixture for a short time: 100 pounds Ajax flakes, 

 60 pounds corn-meal, 20 pounds wheat-bran, 10 pounds wheat-middlings, 

 10 pounds cottonseed-meal. 



Grain mixtures i and 2 were fed in the other rations but in different 

 amounts.
