The average digestion coefficients, e. g. the amount of 
each component digested, out of 100 parts consumed, are: 
Hay from Iwashiro. Hay from Shimosa, 
Total dry matter. 
... 48.7 
47.5 
Organic matter . 
... 52.7 
49.5 
Crude protein. 
... 41.0 
23.5 
Fat. . 
... 43.3 
40.9 
Fibre . 
... 64.6 
63.3 
1ST itrogenfree extract . . . 
... 43.7 
41.2 
Not regarding that 25 and 35 pet. respectively of the 
hay were left uneaten in our experiments, and that coarse 
fodders of such quality will hardly be totally consumed by 
farm animals, the contents of the two specimens in digestible 
nutrients, calculated with the help of the coefficients, are 
found to be as follows : — 
Iwashiro. Shimosa. 
Digestible crude protein . 3.63 0 0 1.64 % 
„ carbohydrates and fat... 47.25 „ 46.36 „ 
Compared with the contents of meadow hay as given 
in Wolff’s tables (p. 13) we are hardly justified in attributing 
the name of “hay ” to these fodders; they properly deserve 
to be designated as “straw” with regard to their nutritive 
value, as well as to their utilization on the farm.
