Nov. i5 ,1925 Net Energy Values of Alfalfa Hay and Alfalfa Meal 995 
Treatment A exhibits considerable diversity in the net energy 
values for both feeds, but especially for the alfalfa meal—a diversity 
which does not permit of a distinction between the values of the two 
feeds; while treatment B gives very closely concordant values and 
virtually identical figures for the hay and for the meal. 
This indication that there is no difference in the nutritive values 
of the two feeds is in harmony with the conclusion of Fries and Kriss, 5 
that the heat production due to the increased muscular activity dur¬ 
ing the intake of feed and water is normally less in amount than that 
required to bring the temperature of the ingested feed and water up 
to that of the body. 
SUMMARY 
The net-energy value of alfalfa hay of excellent quality is essentially 
the same when coarsely cut, in a silage cutter, as when finely ground 
into a meal. 
Probably due to difference in the course of digestion, especially 
with reference to rumination, the finely ground hay was 2.2 per cent 
less digestible, on a dry-matter basis, than was the coarsely cut hay.
