108 STORRS AGRICULTURAL EXPERIMENT STATION. 
here reported indicate that the narrow rations tended to increase 
the percentages of total solids and of fat in the milk to a slight 
degree. A rise of from .2 to .6 in the average percentages of 
fat in milk in favor of the narrow rations is seen in at least four 
of the experiments recorded. ‘The individuality of the cow, 
however, seemed to be an important factor. While in the 
case of some cows a considerable change in the per cent. of 
solids and of fat was noticed, in other cases there seemed to 
be little or no change. 
The percentages of fat in the total solids of the milk was 
larger in at least four of the experiments where the narrow 
rations were fed—that is, the proportion of fat to solids not 
fat seemed to be increased in these instances by the use of 
narrow rations. 2 
With regard to the relative profit from the use of the narrow 
and the wide rations, there seems to be a diversity of opinion, 
but the general verdict of the experiments here recorded is in 
favor of the liberal use of nitrogenous feeding stuffs from the 
standpoint of profit, especially in the Eastern States. Whether 
under different conditions these feeds will prove profitable or 
not depends much upon their relative market values as com- 
pared with other feeding stuffs, such as corn and wheat feeds, 
which contain much less nitrogen. In the Eastern parts of this 
country nitrogenous feeding stuffs are relatively cheaper than 
in the West, and for this reason they can doubtless be used 
here to greater advantage. ‘The soils of the East also are gen- 
erally lacking in nitrogen, and the use of nitrogenous feeding 
stuffs tends to increase soil fertility by furnishing a manure 
rich in nitrogen. 
Experiments by the Storrs Station.—Thesé have been dis- 
cussed in detail in the previous chapter. ‘The especial object 
was the study of the feeding practice of Connecticut farmers. 
The experiments were made at a distance from the Station, and 
without the requisite facilities for complete analyses of the 
milk, and only the percentage of fat was determined. ‘The 
results, therefore, throw comparatively little light on the effect 
of the feed upon the percentage of total solids in the milk, or 
the ratio of fats to total solids, but they emphasize very 
strongly the importance of protein for large yields of milk and
