New York AGRICULTURAL EXPERIMENT STATION 93 1: 
age a little over five years at the time of this feeding trial and 
had been in milk on the average about 5.6 months. 
During the first period mixed clover hay was fed morning and 
night and oat-and-pea forage at noon. The mixed grain fed, 
No. 34, consisted of five parts wheat bran, two parts ground oats, 
five parts corn meal, one part wheat middlings, one part linseed 
meal, O. P., one part cottonseed meal, one part ground flaxseed 
and four parts gluten feed. The grain represented 31.1 per cent. 
of the cost of the ration and supplied 38.4 per cent. of the total 
digestible nutrients. The forage represented 15.4 per cent. of the 
cost of the ration and supplied 24.2 per cent. of the digestible 
nutrients. During the second period alfalfa forage was fed in the 
morning, mixed hay (very little clover) was fed at noon and corn 
forage at night. No change was made in the grain. The grain 
represented 50.5 per cent. of the cost of the ration and supplied 
28.7 per cent. of the digestible nutrients. The forage repre- 
sented 32.4 per cent. of the cost of the ration and supplied 56 8 
per cent. of the total digestible nutrients. There was a small 
average gain in live weight during each period. 
The second ration, having somewhat the wider nutritive ratio, 
contained the same amount of protein as the first, but more fat, 
considerably more total nutrients, and was considerably higher in 
fuel value. The cost of the second ration was somewhat lower. 
There was considerable increase in the average milk yield for the 
second period and the milk and fat cost less — although there was 
a slight decrease in average per cent. of fat in the milk. The 
extremes in daily average milk yield for the first period were 30.2 
pounds and 12.8 pounds and in percentage of fat 6.10 and 2.80. 
The extremes for the second period were 31.9 and 16.2 pounds 
average daily milk yield, and 6.70 and 2.90 average per cent. of 
fat. The foods used showed the composition given in the 
following table:
