Qiiantiti/ (ind Cost of Milk produced per Day — Continued. 



Comments on the Above Results. 



Remembering that during the entire experiment the grain 

 ration remained the same, and that the quantity of coarse 

 fodders fed was in all cases governed by the individual appe- 

 tite of the animal, the following points are wortliy of 

 notice : — 



1. That when the roots were added to the hay ration the 

 flow of milk in four cases out of six increased, in one case 

 remained constant and in one case slightly decreased. The 

 increased yield, however, was not sufficient to pay for the 

 extra cost of the roots, and the total cost of the milk per 

 quart was noticeal)ly increased in this period. 



2. The grain and hay ration produced a comparatively 

 fair yield, l)ut the average cost of production per quart in 

 the case of three cows whose record extends through the 

 three periods was above that for the corn stover and corn 

 and soja-bean ensilage rations. The co.st per quart when hay 

 was fed as the coarse fodder was 2.15 cents, with corn stover 

 but 1.7G cents and with ensilage 1.99 cents. 



3. The yield of milk decreased on an average 25 per 

 cent, during the corn-stover period ; but because of the low
