NET AVAILABLE ENERGY—MAINTENANCE. 
427 
observed and the broken lines that computed respectively for 
standing and lying, while the points indicate the results for each 
period. As computed standing, the results are all practically at or 
below the maintenance point, and their fairly close agreement with 
each other and with those actually observed indicates that the net 
availability of the metabolizable energy of this sample of timothy 
hay was between 63 and 65 per cent. 
Summary.—The foregoing data as to availability are sum- 
marized in the following table, those experiments in which the total 
ration was less than the maintenance requirement being separated 
from those in which ‘more or less gain by the body took place:
