450 MILCH-KINE. 



9th EXPERIMENT. 



35 DAYS AFTER CALVING. 



The same cow, upon green clover, was now producmg 21.2 

 pints of milk a-day, and of the following composition : 



Caseum 8.1 \

This milk evidently presents a larger quantity of butter than ap- 

 pears in any of the preceding analyses. But no hasty conclusion 

 must be drawn from this ; for the succeeding experiments will ex- 

 hibH a change equally sudden in the proportion of the fatty element, 

 but in a different way. 



In a second series of experiments I set myself the task of ascer- 

 taining whether green fodder had any such remarkable influence on 

 the production of milk, and especially of its fatty element, or butter. 



1st EXPERIMENT. 



BEGUN 176 DAYS AFTER THE CALVING. 



The ration here consisted of winter fodder : 



Potatoes equivalent to 16.5 lbs. of hay.

 measured during the last six days. The quantity was 16.3 pints a 

 day, and consisted of ;
