76 STORRS AGRICULTURAL EXPERIMENT STATION. 
herd was again studied December 22, 1895—-January 2, 1896. 
There were eleven animals in each test, the cows being the 
same in both. Five of the animals were grade Jerseys, and 
the rest were natives. ‘The average estimated weight was 775 
pounds, and the average age nine years. At the date of the 
first test the average time since last calf was four months. ‘The 
rations fed are shown in the table herewith. The main change 
made in the second ration was the substitution of clover hay and 
Chicago gluten meal for the oat hay and corn meal fed in the 
first ration. ‘This narrowed the nutritive ratio from 1:9 to about 
1:5, and,.of course, increased the proportion of protein.

The total cost of the ration remained practically the same, 
but the net cost was greatly reduced in-the second test, owing 
to the higher value of the manure. ‘The average daily yield 
of milk was increased during the second test seven-tenths of a 
pound and the butter five-hundredths of a pound over that 
obtained in the first test. The total cost of feed to produce 
100 pounds of milk was reduced four cents, and the cost of feed 
for a pound of butter was reduced two cents, in the second test.
