Colorado Fodders.

DISCUSSION OF RESULTS AND RECAPITULATION 
§175. In Bulletin No. 39 of this Station, I attempted to find 
some way to examine a fodder which would give us more satisfac¬ 
tory information regarding the value of the fodder than the old 
method furnished. I designated it as ‘‘A Study of Alfalfa and 
Some Other Flays”. It is now ten years since that bulletin was 
published and I here present a brief review of the further work 
done in this line, extending it very materially to include the distri¬ 
bution of the nitrogen in the different extracts and also that of the 
pentosans. Further the determinations of the fuel value of the 
fodders and residues obtained by exhausting the fodders with dif¬ 
ferent menstrua and therewith the energy value of the extracts 
themselves have been added. 
§176. The analytical work has been supplemented by diges¬ 
tion experiments made with sheep, using three individuals in each 
experiment. When I commenced this portion of my study, I 
scarcely hoped to be able to carry it to the extent that it has been 
carried; had I foreseen the end, I would certainly have collected the 
urine and included this factor in the work, but even then the work 
would have been incomplete, though it would have been a little more 
satisfactory than it is at present. 
§177. It is not expected that everybody will find interest 
enough in this subject to lead them to read all of the analytical re¬ 
sults to see what errors have been made, and to weigh the force of 
each individual result obtained, so I may be pardoned for giving, 
in the form of a recapitulation, a general statement of the work. 
§178. The fodders studied are alfalfa hay, timothy hay, na¬ 
tive hay, saltbush hay, A triplex argen tea, corn fodder and sorghum 
fodder. 
§179. It seems superfluous to state that we used the best 
quality of these different fodders that we could obtain. The al¬ 
falfa was probably rather old when cut and the hay had been pre¬ 
served in a stack, so that some of it was not in prime condition, 
but, with these two reservations, it would be classed as A ery good 
hay. 
§180. The timothy hay was grown in the mountains and was 
as good a quality as we could obtain. The native hay was, as is 
all the hay to which this name is applied, a mixture .of grasses and 
sedges, and the results obtained with one sample of it will apply 
only in a general way to any other sample. 
§181. The saltbush, A. argentea, was included in this study 
mainly because we need a plant to use in the eastern portion of the 
State as a forage plant. Irrigation is out of the question in this
