96 STORRS AGRICULTURAL EXPERIMENT STATION. 
PERCENTAGE COMPOSITION OF THE FEEDING STUFFS USED. 
Samples of the grain and hay fed in the experiment were 
selected from time to time for the purpose of learning the com- 
position of the feeds used. These were taken in connection 
with the digestion experiments, two of which were made on the 
“narrow” and two onthe “wide” ration. The uneaten residues 
of each animal were also kept separate, the residue of grain 
being separated from the hay as far as possible. 
The composition of the feeds used, and of the residues, is 
shown in Table 17, which precedes. 
DIGESTIBILITY\ OF THE RATIONS: 
In the sheep-feeding experiment of the winter of 1892-93 the 
digestibility of the rations was calculated from average coeff- 
cients of digestibility of the different fodders, taken largely from 
the results of American experiments, and in a few cases from 
German experiments. The digestibility of the fodder is one of 
the most important factors which bear upon its effect on the 
animal, whether fed for growth, fattening, or milk. Any one 
fodder is liable to vary widely in digestibility from the average 
given in tables of compilations, so that even if the feeds used are 
analyzed, a source of error is introduced unless the digestibility 
of the particular ration is also known. 
Two digestion experiments were made on both the narrow and 
the wide ration, two sheep being used in each case. The details 
of these digestion experiments are given in the papers on diges- 
tion experiments with sheep which follows this article. 
The percentage digested of each of the constituents of the 
rations is shown in the following tables: —
