Nov. 27,1916 Energy Values of Red-Clover Hay and Maize Meal 387 
NET ENERGY VALUES 
In computing, finally, the net energy values, by subtracting the sum 
of the losses of chemical energy and the energy expended in feed con¬ 
sumption from the gross energy Qf the feed, we have used first the values 
for the energy expended in feed consumption obtained in these experi¬ 
ments and then have made a second computation, using instead the 
average between these values and those obtained in previous experiments 
as computed in the foregoing paragraph. Table XII gives the final 
results.

SUMMARY 
Results are here reported of five feeding periods with cattle, two with 
differing amounts of clover hay alone and three with clover hay and 
maize meal in differing quantities. 
(1) The metabolizable energy per kilogram of digested organic matter 
was found to be 3.52 therms for the clover hay and 3.76 therms for the 
meize meal as compared with 3.49 therms and 3.80 therms, respectively, 
as previously reported. 
(2) The average increment in heat production caused by the con¬ 
sumption of 1 kgm. of dry matter was as follows: 
Calories 
(a) For clover hay. 954 
(b) For maize meal. 1,143 
(3) When these results are combined with those of previous experi¬ 
ments, the following corrected values for the average heat increment 
per kilogram dry matter are computed: 
Calories 
(a) For clover hay. 973 
(b) For maize meal. 1,289 
(4) The average net energy values per kilogram of dry matter ob¬ 
tained by the use of the foregoing averages were: 
Calories 
(а) For clover hay. 981 
(б) For maize meal.. 1,91
