In experiments of this sort care must be taken to keej^ the 

 basal ration low, so tliat when the food to be tested is added the 

 total ration shall still be below the animal's average require- 

 ment. 



The food cost of the milk produced in case of the three ex- 

 periments was 3.5 per cent, higher for the oat than for the corn 

 ration. If somewhat less of the basal ration had been fed, it 

 is thought that a still greater difference would have been brought 

 out. 



In general, it is believed that while oats are a valuable food, 

 it is not economical to feed them for milk production in Massa- 

 chusetts, and that they are inferior in nutritive value to corn.
