New York AGRICULTURAL EXPERIMENT STATION. 933 
The results of a feeding trial during May, 1894, are given in 
table X. Nine cows were used of the average age of 4.7 years. 
The average time they had been in milk by May 1 was 4.4 months. 
With one kind of grain fed throughout, there was a change from 
corn silage and hay to more of alfalfa forage and less hay, with 
an interval of five days in which both silage and forage were fed 
with the hay. For some weeks preceding this trial the ration 
had been very similar to that fed for the first period here reported. 
For the first period corn silage was fed at noon, clover hay 
morning and night and a mixed grain, No. 38, consisting of five 
parts wheat bran, two parts corn meal, one part wheat middlings, 
one part cotton-seed meal and one part gluten feed. The grain 
cost 41.6 per cent. of the cost of the ration and supplied 33.9 per 
cent, of the total digestible nutrients. The silage represented 
21.4 per cent. of the cost of the ration and supplied 24.7 per cent. 
of the total digestible nutrients. 
For the second short period corn silage was fed in the morning, 
alfalfa forage at noon and clover hay at night. The grain cost 
44.1 per cent. of the cost of the ration and supplied 34.3 per cent. 
of the total digestible nutrients. The silage and forage repre- 
sented 33.3 per cent. of the cost and supplied 42.6 per cent. of the 
digestible nutrients. For the third period alfalfa forage was fed 
morning and noon, clover hay at night and the same grain, No. 38, 
was fed. The grain represented 43.5 per cent. of the cost of the 
ration and supplied 30.3 per cent. of the total digestible nutrients. 
The forage represented 33.7 per cent. of the cost of the ration and 
supplied 48.0 per cent. of the total digestible nutrients. There 
was considerable average loss in weight during each period, the 
average loss in weight per cow for the month being 38.7 pounds. 
The ration for the last period had a much narrower ratio than 
that of the first. There was an increase in the amount of digesti- 
ble protein, fat and total nutrients, and the fuel value was higher. 
_ The cost of the ration was somewhat lower. The milk yield for 

_ the last period was about the same, with a slight improvement in 
- quality. The cost of milk and fat was less. The results in the 
short intermediate period were somewhat better than in the first 
or last. For the first period the greatest daily average milk 
yield was 34.9 pounds and the smallest 19.2 pounds. The highest 
average per cent. of fat was 7.00 and the lowest 3.05. For
