A STUDY OF RATIONS FED TO MILCH COWS. 29 
The studies of the third herd included tests No. 43 and No. 
45. ‘he first test, of twelve days duration, began February 8, 
1897; the second test, of equal length, began March 8. The 
cows were watered at a brook about a quarter of a mile distant. 
During the first test the grain feed was mixed in the proportion 
of four parts fine wheat feed, four parts Rockford gluten feed, 
one part corn meal, one part corn and cob meal, and one part old 
process linseed meal. ‘The corn stover was fed without cutting 
into short lengths and a large amount of butts was left uneaten. 
It was estimated that about 140 pounds of butts were removed 
from the mangers during the test, or an average of about 1.3 
pounds per cow per day. The composition of these was 
assumed from analyses of corn stover butts left in sheep feed- 
ing experiments. In calculating the results, the nutrients 
rejected in the butts were subtracted from the total nutrients 
in the feeding stuffs actually fed. 
The cows were not all fed alike. Cows 7 and g had corn and 
cob meal, and cow 8 linseed meal substituted for a portion of 
the grain mixture. In the following table the average nutrients 
fed each group of cows is shown, as well as the average amounts 
for the whole herd.
