generally upon their estimates rather than upon actual weigh- 
ings of the amounts fed each day to the cows. The quantities of 
digestible nutrients were calculated from average analyses and 
from assumed figures for digestibility of each class of nutrients. 
The average of these rations indicates the use of less protein 
and more fuel ingredients of food by these intelligent farmers 
and breeders than the commonly quoted feeding standards call 
for. ‘This, however, is not at all unnatural. 
The relative abundance and cheapness of feeding stuffs con- 
taining the fats, and especially carbohydrates, has doubtless 
led to their very extensive use in this country, but the fact 
that intelligent men feed them liberally does not imply, and 
much less does it prove, that we are using them wisely. 
The second average in the table is that of twenty-nine studies 
of the feeding practice of Connecticut dairymen, here reported. 
It will be observed that they are, on the whole, more liberal 
and, especially, that they contain considerably larger propor- 
tions of protein than the average of the larger number of rations 
compiled by the Wisconsin Station. 
The next ration represents the average of nine which were 
suggested by the Station to farmers as the result of observa- 
tions upon their actual feeding practice. In each of these 
cases, a study was first made of the materials fed and the milk 
produced. A change in the ration was then suggested by the 
Station and adopted by the owner of the herd. This change 
consisted partly in using more nitrogenous feeding stuffs and 
partly in replacing the finer and more valuable kinds of hay by 
coarser and cheaper fodder, as explained in detail in the accounts 
of the experiments. In general the new rations with the 
larger amounts of protein and narrower nutritive ratios were 
found decidedly advantageous, as will be explained beyond. 
The next is a feeding standard tentatively suggested by the 
Station. ‘This, it will be observed, contains the same amount of 
protein as is called for in the German standard by Wolff, which 
follows next in the table. ‘The amounts of fuel ingredients 
are, however, a little larger, so that the fuel value is 31,000 
calories as compared with 29,600 in the German standard ration. 
While the German figures probably come nearer to the physio- 
logical demand for the average milch cow, especially if the 
amount of milk is to be at all considered, this more liberal
