918 Report oF THE First AssISTANT OF THE 
The results obtained in a feeding trial from May 17 to July 15, 
1893, are shown in table VII. There was a change from corn 
silage to rye and alfalfa forage, then to alfalfa forage and finally 
to oat-and-pea forage. Ten cows were used of the average age 
June 1 of 4.8 years. They had been in milk at that date about 
4.5 months. 
From May 17 to May 31, inclusive, corn silage was fed morning 
and noon, and hay at night. The grain fed, No. 31, consisted of 
six parts of wheat bran, one part ground oats, two parts corn 
meal, two parts wheat middlings, one part linseed meal, O. P., 
and one part cottonseed meal. This same ration had been fed 
for several weeks preceding. The cost of grain was 45.4 per 
cent. of the cost of the ration and the grain supplied 40.2 per 
cent. of the digestible nutrients. The silage represented 35.6 per 
cent. of the cost of the ration and supplied 35.5 per cent of the 
digestible nutrients. 
From June 1 to June 10 alfalfa forage was fed in the morn- 
ing, rye forage at noon, and hay at night. The mixed grain, No. 
32, consisted of five parts wheat bran, one part ground oats, 
four parts corn meal, one part wheat middlings and one part 
linseed meal, N. P. The grain represented 50.6 per cent. of the 
cost of the ration and the forage 27.3 per cent. The grain sup- 
plied 34.5 per cent. of the total digestible nutrients and the 
forage, 45.2 per cent. 
From June 11 to June 30, inclusive, alfalfa forage was fed in 
the morning and at noon, and hay at night. The same mixed 
grain, No. 32, was fed. The grain represented 47.5 per cent. of 
the cost of the ration and the forage 33.7 per cent. The grain 
supplied 32.7 per cent. of the total digestible nutrients and the 
forage supplied 49.8 per cent. 
From July 1 to 15 oat-and-pea forage was fed in the morn- 
ing and at noon, and a mixed hay atnight. Mixed grain, No. 32, 
was again fed. The grain represented 48.4 per cent. of the cost 
of the ration and the forage 35.3 per cent. The grain supplied 
36.7 per cent. of the total digestible nutrients and the forage 46.2 
per cent. There was an average loss in weight during the first 
period of 16.5 pounds and a slight average gain during each of 
the other three periods of a little over one pound.
