Table IV. — Average Daily Rations for Each Cow (Pounds). 



Table III. shows the total feed consumption of each animal 

 in the two herds. Table IV. shows the average daily consump- 

 tion of each cow in both herds. In the first period the cows 

 in Herd I. consumed daily from 6 to 8 pounds of grain and 

 those in Herd II. from 5 to 10 pounds, the average being the 

 same in both herds. The cows in Herd 11. consumed rather 

 more hay than those in Herd I. In the second period Herd I. 

 continued to consume the same amount of grain as in the first 

 period and substantially the same amount of hay. In the case 

 of Herd 11. it became necessary to cut down the amount of grain 

 for two of the cows, so that the daily total average was i/o 

 pound less than in the first period. The soy bean meal replaced 

 the normal ration in amounts varying from II/2 to 3 pounds 

 per diem, with a daily average of 2.3 pounds. The amount of 

 hay was about the same as that consumed in the first period. 

 In the third period Herd I. continued to consume the same 

 kinds and amounts of food as in the previous two periods. 

 With Herd II. the soy bean meal was replaced by an equal 

 amount of the normal grain ration, and to this was added for 

 each cow from .25 to .83 of a pound of soy bean oil, with an 

 average daily consumption of .6 of a pound. This amount 

 of oil did not seem to in any way interfere with the normal
