THE CONNECTICUT AGRICULTURAL 



The composition thus found diifers somewhat from the composi- 

 tion of the hay and corn fodder as fed, and indicates a greater 

 digestibility. The following digestion coefficients may be as- 

 sumed to represent fairly the digestibility of the various feeding- 

 stiiffs here used. Those for the maize fodder are not those given 

 under that head in the tables, but are the average coefficients for 

 Wolff's " Inferior" meadow hay, with which this sample of corn 

 fodder agrees approximately in composition. The only coeffi- 

 cients which we have for maize fodder are the resiilts of but a 

 single experiment on fodder of unusually excellent quality and. 

 hence are much too large for a sample of this sort.

The dry matter of our fodders, then, contains the following 

 percentages of digestible nutrients : —

 The ration per day and head was, therefore, thus constituted: — 



The average yield of milk per day and head by the whole herd 

 for the week previous to these observations was 7.7 quarts.
