50 STORRS AGRICULTURAL EXPERIMENT STATION. ~ 
The following discussion includes only the 15 animals entering 
into both tests. These included ro Guernseys, 4 Jerseys, and 1 
Ayrshire. The average estimated weight. was 825 pounds each. 
The average age was five years. At date of first test.the average 
time since last calf was dropped was five months. None of the 
cows were within four months of calving. The statistics of 
the rations fed are summarized in the following table. , 
The German standard and the ration tentatively suggested on 
page 46 of this Report and calculated for animals of 825 pounds, 
live weight, are appended for comparison.

The second ration as fed was larger and hence more expensive 
than was intended; nevertheless the total cost of the second 
ration was 5 cents less per head and the net cost was 5% cents 
less than the first. The use of cotton seed meal reduces the net 
cost of the second ration very materially, for the estimated value 
of the manure obtainable from cotton seed meal equals its cost.
